Red and Blue Voters Live in Different Economies

Wow... if you want some graphics that powerfully describe our current political malaise, check out Edsall's Op-Ed piece in the NYTimes. Here is a graph showing how economic output and income for Democratic and Republican House districts diverged over the last decade - two different economies that are diverging rapidly:

Another Edsall piece notes that insecurity caused by rapid cultural change as well as economic insecurity has generated a class of voters who feel powerless and angry, and actually feel a need for the chaos Trump generates - that they hope might disrupt the system that disadvantages them.

Mindfulness training and attentional control of mind-wandering

Several studies have suggested that mindfulness training can strengthen the connections between the networks in our dorsolateral prefrontal cortex [DLPFC] attentional executive control network and those supporting the posterior cingulate cortex [PCC] default mode network active in mind-wandering. Davidson and his colleagues have expanded on this to see whether a Mindfulness-Based Stress Reduction (MBSR) course can increase DLPFC-PCC connectivity:

Mindfulness meditation training has been shown to increase resting state functional connectivity between nodes of the frontoparietal executive control network (dorsolateral prefrontal cortex [DLPFC]) and the default mode network (posterior cingulate cortex [PCC]). We investigated whether these effects generalized to a Mindfulness-Based Stress Reduction (MBSR) course, and tested for structural and behaviorally relevant consequences of change in connectivity. Healthy, meditationnaïve adults were randomized to either MBSR (N=48), an active (N=47) or waitlist (N=45) control group. Participants completed behavioral testing, resting state fMRI scans, and diffusion tensor scans at pre-randomization (T1), post-intervention (T2) and approximately 5.5 months later (T3). We found increased T2-T1 PCC–DLPFC resting connectivity for MBSR relative to control groups. Although these effects did not persist through long-term follow-up (T3-T1), MBSR participants showed a significantly stronger relationship between days of practice (T1 to T3) and increased PCC–DLPFC resting connectivity than participants in the active control group. Increased PCC–DLPFC resting connectivity in MBSR participants was associated with increased microstructural connectivity of a white matter tract connecting these regions, and increased self reported attention. These data show that MBSR increases PCC–DLPFC resting connectivity, which is related to increased practice time, attention, and structural connectivity.

Loving kindness meditation slows cellular aging?

I like to be generous, loving, kind and nice, but a recent PsyPost article on the slowing of cellular aging by loving-kindness meditation triggered my bullshit detector. I first pass on the summary and abstract of the work referenced in the article by Le Nguyen et al., and then get a bit into the details available only to those who have journal access (motivated readers can request a PDF of the article from me). It is a noble and complicated effort, with proper double blind controls, but with statistics compromised by a small sample size and measured changes in DNA telomere length (a proxy for aging) over a short period of time much larger than would be expected from longer terms studies. While I would like to believe the conclusions drawn by the authors, I have to remain wary of accepting them.

Highlights

•Over 12 weeks, loving-kindness meditation buffered telomere attrition.

•Telomere length decreased in the mindfulness group and the control group.

•The loving-kindness group showed less telomere attrition than the control group.

Abstract

Combinations of multiple meditation practices have been shown to reduce the attrition of telomeres, the protective caps of chromosomes (Carlson et al., Cancer, 121 (2015), pp. 476-484). Here, we probed the distinct effects on telomere length (TL) of mindfulness meditation (MM) and loving-kindness meditation (LKM). Midlife adults (N = 142) were randomized to be in a waitlist control condition or to learn either MM or LKM in a 6-week workshop. Telomere length was assessed 2 weeks before the start of the workshops and 3 weeks after their termination. After controlling for appropriate demographic covariates and baseline TL, we found TL decreased significantly in the MM group and the control group, but not in the LKM group. There was also significantly less TL attrition in the LKM group than the control group. The MM group showed changes in TL that were intermediate between the LKM and control groups yet not significantly different from either. Self-reported emotions and practice intensity (duration and frequency) did not mediate these observed group differences. This study is the first to disentangle the effects of LKM and MM on TL and suggests that LKM may buffer telomere attrition.

Fig. 1. Descriptive Mean and Standard Errors of Changes in TL per Experimental Conditions. (TL is expressed as the ratio (T/S) of telomeric (T) to single copy (S) gene product for a particular blood sample)

Apart from picking apart their statistics and the "controls for demographic covariates," the discussion paragraph that troubles me most is:

The difference in telomere length between the Control and LKM groups was .048 T/S ratio after demographic covariates were considered. Based on comparison of T/S ratios and telomere length measured by Southern blot in a series of quality control samples from the same lab, we estimated this difference of .048 T/S ratio to be 115 basepairs. This TL decrease over the 12-week period appears to be large compared to studies of TL change with much longer time periods (Müezzinler et al., Obes. Rev., 15 (2014), pp. 192-201). It is possible that this reflects short term dynamic change, or potential systematic differences in the collection and/or assay of baseline and follow-up samples. The fact that DNA extraction and assay were done as one batch (all samples from Time 1 and Time 2) argues against the latter concern, although we cannot completely rule out other potential unaccounted for systematic differences. Although it is unknown whether this effect remains longer than 3 weeks post-intervention, the current study demonstrated proof of concept for the malleability of TL changes, and that certain forms of meditation, in this case loving-kindness meditation, may buffer against telomere erosion.

After several paragraphs of other reservations and cautions on the data, the authors state:

...one should interpret the differences in TL changes here with caution, treating them as evidence for “apparent” rather than true alterations in TL.

In balance, the PsyPost article title: "Study provides evidence that loving-kindness meditation slows cellular aging" is wrong.

Gender neutral pronouns reduce bias in favor of traditional gender roles

An interesting study by Tavits and Pérez on Sweden's 2015 incorporation into the Swedish Academy Glossary (which sets norms for Sweden's language) of the gender-neutral pronoun hen. A majority of Swedes now use hen alongside the explicitly gendered hon (she) and han (he) as part of their grammatical toolkit.

Significance

Evidence from 3 survey experiments traces the effects of gender-neutral pronoun use on mass judgments of gender equality and tolerance toward lesbian, gay, bisexual, and transgender (LGBT) communities. The results establish that individual use of gender-neutral pronouns reduces the mental salience of males. This shift is associated with people expressing less bias in favor of traditional gender roles and categories, as manifested in more positive attitudes toward women and LGBT individuals in public affairs.

Abstract

To improve gender equality and tolerance toward lesbian, gay, bisexual, and transgender (LGBT) communities, several nations have promoted the use of gender-neutral pronouns and words. Do these linguistic devices actually reduce biases that favor men over women, gays, lesbians, and transgender individuals? The current article explores this question with 3 large-scale experiments in Sweden, which formally incorporated a gender-neutral pronoun into its language alongside established gendered pronouns equivalent to he and she. The evidence shows that compared with masculine pronouns, use of gender-neutral pronouns decreases the mental salience of males. This shift is associated with individuals expressing less bias in favor of traditional gender roles and categories, as reflected in more favorable attitudes toward women and LGBT individuals in public life. Additional analyses reveal similar patterns for feminine pronouns. The influence of both pronouns is more automatic than controlled.

The power of "cute"

I want to point MindBlog readers to an article by Simon May at aeon.co that encapsulates the contents of his new book "The Power of Cute" (2019), and to a Trends in Cognitive Sciences review article by Kringelbach et al. on cuteness that summarizes work on brain activities underlying survival related cuteness responses. The latter article's introduction notes that the prevailing view of cuteness...

...came from the founding fathers of ethology, Nobel prizewinners Konrad Lorenz and Niko Tinbergen. They proposed that the cute facial features of infants form a ‘Kindchenschema’ (infant schema), a prime example of an ‘innate releasing mechanism’ that unlocks instinctual behaviours...These characteristics contribute to ‘cuteness’ and propel our caregiving behaviours, which is vital because infants need our constant attention to survive and thrive. Infants attract us through all our senses, which helps make cuteness one of the most basic and powerful forces shaping our behaviour.

May considers the increasing popularity of child-like figures in popular culture and asks:

In such uncertain and uneasy times, and with so much injustice, hate and intolerance threatening the world, don’t we have more serious things to focus on than the escapades of that feline girl-figure Hello Kitty? Or Pokémon, the video-game franchise that’s hot again in 2019...The craze for all things cute is motivated, most obviously, by the urge to escape from precisely such a threatening world into a garden of innocence in which childlike qualities arouse deliciously protective feelings, and bestow contentment and solace. Cute cues include behaviours that appear helpless, harmless, charming and yielding, and anatomical features such as outsize heads, protruding foreheads, saucer-like eyes, retreating chins and clumsy gaits.

May suggests that the increasingly popularity of cuteness derives not only from the 'sweet' end of the whole spectrum of cuteness but also from moving towards the 'uncanny' and ambiguous end, a....

...faintly menacing subversion of boundaries – between the fragile and the resilient, the reassuring and the unsettling, the innocent and the knowing – when presented in cute’s frivolous, teasing idiom, is central to its immense popularity... ‘unpindownability’, as we might call it, that pervades cute – the erosion of borders between what used to be seen as distinct or discontinuous realms, such as childhood and adulthood – is also reflected in the blurred gender of many cute objects such as Balloon Dog or a lot of Pokémon. It is reflected, too, in their frequent blending of human and nonhuman forms, as in the cat-girl Hello Kitty. And in their often undefinable age...In such ways, cute is attuned to an era that is no longer so wedded to such hallowed dichotomies as masculine and feminine, sexual and nonsexual, adult and child, being and becoming, transient and eternal, body and soul, absolute and contingent, and even good and bad.

Although attraction to such cute objects as the mouthless, fingerless Hello Kitty can express a desire for power, cuteness can also parody and subvert power by playing with the viewer’s sense of her own power, now painting her into a dominant pose, now sowing uncertainty about who is really in charge...

Psychological adaptation to the apocalypse - meditate, or just be happy?

In this post, not exactly an upper, I point first to two in-your-face articles on how we ought to be afraid, very afraid, about humanity's future technological and ecological environment, and then note two pieces of writing on psychological adaptations that might dampen down the full turn on of our brains' fear machinery.

Novelist Jonathan Franzen does a screed very effective at scaring the bejesus out of us. His basic argument: “The climate apocalypse is coming. To prepare for it, we need to admit that we can’t prevent it.” A chorus of criticism has greeted Franzen's article: "Franzen is wrong on the science, on the politics, and on the psychology of human behavior as it pertains to climate change." (See also Chrobak.)

And, for alarm on our looming digital environment, The 6,000 word essay by Glenn S. Gerstell, general counsel of the National Security, and summarized by Warzel, should do the job. The first nation to crack quantum computing (China or the US) will rule the world! 

So, how do we manage to wake up cheerful in the morning? Futurist Yuval Harari offers his approach in Chapter 21 of his book "21 Lessons for the 21st century," by describing his experience of learning to meditate, starting with the initial instructions (to observe your process of breathing) in his first Vipassana meditation course. He now meditates two hours every day.

The point is that meditation is a tool for observing the mind directly...For at least two hours a day I actually observe reality as it is, while for the other twenty-two hours I get overwhelmed by emails and tweets and cute-puppy videos. Without the focus and clarity provided by this practice, I could not have written Sapiens or Homo Deus.

A glimmer of hopefulness can also be obtained by reading books in the vein of Pinker's "Enlightenment Now", which documents again and again, for many areas, how dire predictions about the future have not come to pass. The injunction here would be to be optimistic, not a bad idea, given the recent PNAS article by Lee et al. documenting that the lifespan of optimistic people, on average, is 11 to 15% longer.

Twitter is making us dumber.

Stanley-Becker points to some research providing hardly surprising evidence that communicating about complex issues using 280 character chunks of text dumbs down the understanding of twitter users. Using Twitter to teach literature has an overall negative effect on students’ average achievement, with the effect being strongest on students who usually perform better. Numerous schools have started to utilize twitter discussion among students assuming that this would enhance intellectual attainment, but in fact it undermines it.

Can we reverse our biological age? The usual media hysteria...

I must have seen at least 10 of my media inputs hyping a small study by Fahy et al. (9 white men, and lacking controls) pointed to by Abbott suggesting that the body's epigenetic clock might be reversed. The study actually had the goal of seeing whether human growth hormone could stimulates regeneration of the thymus gland and enhance immune function. Because the hormone can promote diabetes, the trial included two widely used anti-diabetic drugs, dehydroepiandrosterone (DHEA) and metformin, in the treatment cocktail. (Metformin is being evaluated as an anti-aging drug in several large scale studies).

Checking the effect of the drugs on the participants’ epigenetic clocks was an afterthought. The clinical study had finished when Fahy approached Horvath to conduct an analysis. (Epigenetic clocks are constructed by selecting sets of DNA-methylation sites across the genome. In the past few years, Horvath — a pioneer in epigenetic-clock research — has developed some of the most accurate ones)...Horvath used four different epigenetic clocks to assess each patient’s biological age, and he found significant reversal for each trial participant in all of the tests. “This told me that the biological effect of the treatment was robust,” he says. What’s more, the effect persisted in the six participants who provided a final blood sample six months after stopping the trial, he says.

The understandable excitement over this result is probably out of proportion to the probability it will be confirmed in larger experiments with proper controls.

Training to reduce cognitive biases.

Sellier et al. show that students assigned to solve a business case exercise are less likely to choose an inferior confirmatory solution when they have previously undergone a debiasing-training intervention:

The primary objection to debiasing-training interventions is a lack of evidence that they improve decision making in field settings, where reminders of bias are absent. We gave graduate students in three professional programs (N = 290) a one-shot training intervention that reduces confirmation bias in laboratory experiments. Natural variance in the training schedule assigned participants to receive training before or after solving an unannounced business case modeled on the decision to launch the Space Shuttle Challenger. We used case solutions to surreptitiously measure participants’ susceptibility to confirmation bias. Trained participants were 29% less likely to choose the inferior hypothesis-confirming solution than untrained participants. Analysis of case write-ups suggests that a reduction in confirmatory hypothesis testing accounts for their improved decision making in the case. The results provide promising evidence that debiasing-training effects transfer to field settings and can improve decision making in professional and private life.

How personal and professional conduct relate to one another.

From Griffin et al.:

Significance

The relative importance of personal traits compared with context for predicting behavior is a long-standing issue in psychology. This debate plays out in a practical way every time an employer, voter, or other decision maker has to infer expected professional conduct based on observed personal behavior. Despite its theoretical and practical importance, there is little academic consensus on this question. We fill this void with evidence connecting personal infidelity to professional behavior in 4 different settings.

Abstract

We study the connection between personal and professional behavior by introducing usage of a marital infidelity website as a measure of personal conduct. Police officers and financial advisors who use the infidelity website are significantly more likely to engage in professional misconduct. Results are similar for US Securities and Exchange Commission (SEC) defendants accused of white-collar crimes, and companies with chief executive officers (CEOs) or chief financial officers (CFOs) who use the website are more than twice as likely to engage in corporate misconduct. The relation is not explained by a wide range of regional, firm, executive, and cultural variables. These findings suggest that personal and workplace behavior are closely related.

Training wisdom - the Illeist (third person) method.

I think my most sane moments are those when I experience myself as watching, in third-person mode, rather than “being” Deric, the immersed actor. Science journalist David Robson does an essay on this perspective in Aeon, “Why speaking to yourself in the third person makes you wiser,” noting that this ancient rhetorical method, used by Julius Caesar and termed ‘illeism’ in 1809 by the poet Coleridge (latin ille meaning ‘he, that’) can clear the emotional fog of simple rumination, shifting perspective to see past biases. Robson notes the work of Igor Grossmann at the University of Waterloo in Canada, whose aim is:

...to build a strong experimental footing for the study of wisdom, which had long been considered too nebulous for scientific enquiry. In one of his earlier experiments, he established that it’s possible to measure wise reasoning and that, as with IQ, people’s scores matter. He did this by asking participants to discuss out-loud a personal or political dilemma, which he then scored on various elements of thinking long-considered crucial to wisdom, including: intellectual humility; taking the perspective of others; recognising uncertainty; and having the capacity to search for a compromise. Grossmann found that these wise-reasoning scores were far better than intelligence tests at predicting emotional wellbeing, and relationship satisfaction – supporting the idea that wisdom, as defined by these qualities, constitutes a unique construct that determines how we navigate life challenges.

The abstract from Grossmann et al.:

We tested the utility of illeism – a practice of referring to oneself in the third person – for the trainability of wisdom-related characteristics in everyday life: i) wise reasoning (intellectual humility, open-mindedness in ways a situation may unfold, perspective-taking, attempts to integrate different viewpoints) and ii) accuracy in emotional forecasts toward close others. In a month-long field experiment, people adopted either the third-person training or first-person control perspective when describing their most significant daily experiences. Assessment of spontaneous wise reasoning before and after the intervention revealed substantial growth in the training (vs. control) condition. At the end of the intervention, people forecasted their feelings toward a close other in challenging situations. A month later, these forecasted feelings were compared against their experienced feelings. Participants in the training (vs. control) condition showed greater alignment of forecasts and experiences, largely due to changes in their emotional experiences. The present research demonstrates a path to evidence-based training of wisdom-related processes via the practice of illeism.

Robson finds this work particularly fascinating,

...considering the fact that illeism is often considered to be infantile. Just think of Elmo in the children’s TV show Sesame Street, or the intensely irritating Jimmy in the sitcom Seinfeld – hardly models of sophisticated thinking. Alternatively, it can be taken to be the sign of a narcissistic personality – the very opposite of personal wisdom. After all, Coleridge believed that it was a ruse to cover up one’s own egotism: just think of the US president’s critics who point out that Donald Trump often refers to himself in the third person. Clearly, politicians might use illeism for purely rhetorical purposes but, when applied to genuine reflection, it appears to be a powerful tool for wiser reasoning.

For an example of third person usage reflecting not wisdom, but a narcissistic personality, look no further than our current president, Donald Trump, as noted in this Washington Post piece by Rieger.

Infants expect leaders to right wrongs

From Stavans and Baillargeon:

Anthropological and psychological research on direct third-party punishment suggests that adults expect the leaders of social groups to intervene in within-group transgressions. Here, we explored the developmental roots of this expectation. In violation-of-expectation experiments, we asked whether 17-mo-old infants (n = 120) would expect a leader to intervene when observing a within-group fairness transgression but would hold no particular expectation for intervention when a nonleader observed the same transgression. Infants watched a group of 3 bear puppets who served as the protagonist, wrongdoer, and victim. The protagonist brought in 2 toys for the other bears to share, but the wrongdoer seized both toys, leaving none for the victim. The protagonist then either took 1 toy away from the wrongdoer and gave it to the victim (intervention event) or approached each bear in turn without redistributing a toy (nonintervention event). Across conditions, the protagonist was either a leader (leader condition) or a nonleader equal in rank to the other bears (nonleader condition); across experiments, leadership was marked by either behavioral or physical cues. In both experiments, infants in the leader condition looked significantly longer if shown the nonintervention as opposed to the intervention event, suggesting that they expected the leader to intervene and rectify the wrongdoer’s transgression. In contrast, infants in the nonleader condition looked equally at the events, suggesting that they held no particular expectation for intervention from the nonleader. By the second year of life, infants thus already ascribe unique responsibilities to leaders, including that of righting wrongs.

Loss of control in aging cells.

Wow...experiments like those of Pereda et al. make me feel rather fatalistic and resigned to the aging process, notwithstanding all the numerous pie in the sky biotech startups that are trying to find magic bullets that will reverse human aging. They note that deterioration in learning and memory with aging is not accompanied by obvious increases in nerve cell death, and so looked for more subtle changes that might be a play. They created transgenic mice that expressed a calcium sensor specifically in presynaptic terminals of the CA1 region of the hippocampus, allowing them to measure how calcium signaling altered with age. Older animals showed increased calcium influx into the neurons and persistently increased concentration of calcium in resting neurons, most likely caused by by an age‐dependent change in the properties or numbers of presynaptic calcium channels. Higher calcium altered neuronal transmission with parallel loss of cognitive function in the animals. Interestingly, reducing extracellular calcium made old synapses behave more like younger ones, and raising extracellular calcium made young synapses act like old ones.  Here is their technical abstract:

The loss of cognitive function accompanying healthy aging is not associated with extensive or characteristic patterns of cell death, suggesting it is caused by more subtle changes in synaptic properties. In the hippocampal CA1 region, long‐term potentiation requires stronger stimulation for induction in aged rats and mice and long‐term depression becomes more prevalent. An age‐dependent impairment of postsynaptic calcium homeostasis may underpin these effects. We have examined changes in presynaptic calcium signalling in aged mice using a transgenic mouse line (SyG37) that expresses a genetically encoded calcium sensor in presynaptic terminals. SyG37 mice showed an age‐dependent decline in cognitive abilities in behavioural tasks that require hippocampal processing including the Barnes maze, T‐maze and object location but not recognition tests. The incidence of LTP was significantly impaired in animals over 18 months of age. These effects of aging were accompanied by a persistent increase in resting presynaptic calcium, an increase in the presynaptic calcium signal following Schaffer collateral fibre stimulation, an increase in postsynaptic fEPSP slope and a reduction in paired‐pulse facilitation. These effects were not caused by synapse proliferation and were of presynaptic origin since they were evident in single presynaptic boutons. Aged synapses behaved like younger ones when the extracellular calcium concentration was reduced. Raising extracellular calcium had little effect on aged synapses but altered the properties of young synapses into those of their aged counterparts. These effects can be readily explained by an age‐dependent change in the properties or numbers of presynaptic calcium channels.

Interindividual variability - rather than universality - in facial-emotion perception.

Brooks et al. do experiments suggesting that the representational structure of emotion expressions in visual face-processing regions may be shaped by idiosyncratic conceptual understanding of emotion categories:

Significance

Classic theories of emotion hold that emotion categories (e.g., Anger and Sadness) each have corresponding facial expressions that can be universally recognized. Alternative approaches emphasize that a perceiver’s unique conceptual knowledge (e.g., memories, associations, and expectations) about emotions can substantially interact with processing of facial cues, leading to interindividual variability—rather than universality—in facial-emotion perception. We find that each individual’s conceptual structure significantly predicts the brain’s representational structure, over and above the influence of facial features. Conceptual structure also predicts multiple behavioral patterns of emotion perception, including cross-cultural differences in patterns of emotion categorizations. These findings suggest that emotion perception, and the brain’s representations of face categories, can be flexibly influenced by conceptual understanding of emotions.

Abstract

Humans reliably categorize configurations of facial actions into specific emotion categories, leading some to argue that this process is invariant between individuals and cultures. However, growing behavioral evidence suggests that factors such as emotion-concept knowledge may shape the way emotions are visually perceived, leading to variability—rather than universality—in facial-emotion perception. Understanding variability in emotion perception is only emerging, and the neural basis of any impact from the structure of emotion-concept knowledge remains unknown. In a neuroimaging study, we used a representational similarity analysis (RSA) approach to measure the correspondence between the conceptual, perceptual, and neural representational structures of the six emotion categories Anger, Disgust, Fear, Happiness, Sadness, and Surprise. We found that subjects exhibited individual differences in their conceptual structure of emotions, which predicted their own unique perceptual structure. When viewing faces, the representational structure of multivoxel patterns in the right fusiform gyrus was significantly predicted by a subject’s unique conceptual structure, even when controlling for potential physical similarity in the faces themselves. Finally, cross-cultural differences in emotion perception were also observed, which could be explained by individual differences in conceptual structure. Our results suggest that the representational structure of emotion expressions in visual face-processing regions may be shaped by idiosyncratic conceptual understanding of emotion categories.

From "Love Your Enemies" - Arthur Brooks on Haidt's Moral Foundations Theory

I have read through Arthur Brooks' new book, "Love your Enemies," which addresses the many facets of our current political polarization, with the goal of suggesting some ways to ameliorate our current impasse. While I'm tempted to pass on an abstracted version of the main points of each of the book chapters, as I have done for several other books that have influenced me, I'm going to restrict myself to passing on some clips from Chapter 4 "How Can I Love my Enemies if They are Immoral," in which he does a nice summary of the ideas and work of Jonathan Haidt. At the end of the clips I attach a graphic from one of Haidt's lectures that summarizes his findings.

...“moral foundations theory,”... specifically addresses how conservatives and liberals differ in their moral views. Haidt was finding that certain ideas of morality are innate and that “the worst idea in all of psychology is the idea that the mind is a blank slate at birth.”* His research showed that we are in fact born with particular moral foundations that make it easy for us to learn certain ideas of right and wrong, and hard to learn others. Using survey data for hundreds of thousands of individuals, Haidt was finding that there are in fact five innate moral values that exist among humans of all races and cultures, which he calls the “five foundations of morality.” They are: (1) fairness, (2) care for others, (3) respect for authority, (4) loyalty to one’s group, and (5) purity or sanctity. (Later, he added liberty to the list.) Haidt’s research has shown that of these five moral foundations, the first two—fairness and care—are nearly universal. Except for sociopaths, almost everyone—conservative or liberal, young or old, religious or nonreligious—believes in fairness and compassion to others.

Conservatives look at all this and often conclude that liberals are less moral than they are, but the science shows this is not true. Liberals are not less moral; they simply have fewer moral foundations. According to Haidt’s research, “Liberals have a kind of a two-channel, or two-foundation morality” while “conservatives have more of a . . . five-channel morality.” All of us, regardless of where we sit on the political spectrum, care about social morality, treating others with fairness and compassion. By contrast, personal moral values, such as sexual purity, respect for authority, and tribal loyalty—to which conservative politicians often give greater emphasis—resonate deeply with only a part of the population. When it comes to loyalty, authority, and purity, conservatives are from Mars, and liberals are from Venus. Or vice versa, I’m not sure. I just know it’s different planets.

Even in an age that celebrates diversity, most people assiduously avoid those who hold different moral values. Indeed, people avoid those with different values more than they do people of different racial backgrounds. In one study with undergraduate students, Haidt and his colleagues found that “in fraternity admissions, fraternity brothers were happy to admit people who were demographically different from themselves, although they avoided candidates who had strong moral or political values that differed either from the group as a whole, or from themselves as individuals.” He also found that in choosing a study partner, most undergraduates did not care about racial differences, “but political/moral differences generally made a candidate less attractive.” Haidt’s work is consistent with more recent research that shows the starkest dividing line in America today is not race, religion, or economic status, but rather party affiliation. In fact, scholars at Stanford and Princeton have found that political partisans in America now take a more discriminatory view of those in the opposing party than they do of people of other races.

You may be genetically predisposed to a conservative, five-channel moral foundation, but that doesn’t mean you have to be a conservative if your intellect tells you otherwise. Think deeply. Listen to the other side. Reflect on what others are saying. Then ask yourself not just how you feel, but what you think is right. We’re not slaves. We’re not shackled to a pipe in the basement of our own built-in genetic morality. In his book The Birth of the Mind, the eminent brain scientist Gary Marcus writes, “‘Built-in’ does not mean unmalleable; it means organized in advance of experience.” When it comes to our moral outlook, Marcus says, “Nature provides a first draft, which experience then revises.” It is up to each of us to create the next drafts of our moral minds. We should constantly be evaluating whether our particular expression of our moral values is the right one, much less the only legitimate expression of those values. Doing so requires the humility to recognize that none of us has a monopoly on truth. The left favors redistribution; the right, meritocracy. But if we had a completely redistributionist society we’d be the Soviet Union; if we had a complete meritocracy, millions would be starving. There is a sweet spot between the two and we should all be searching together to find it.

What we see is biased by ongoing neural activity.

Rassi et al. (open source) show that ongoing neural activity in our brain, as in the fusiform face area, can influence what we perceive in an ambiguous sensory stimulus such as the Rubin face/vase illusion.

Significance

Ongoing neural activity influences stimulus detection—that is, whether or not an object is seen. Here, we uncover how it could influence the content of what is seen. In ambiguous situations, for instance, ongoing neural fluctuations might bias perception toward one or the other interpretation. Indeed, we show increased information flow from category-selective brain regions (here, the fusiform face area [FFA]) to the primary visual cortex before participants subsequently report seeing faces rather than a vase in the Rubin face/vase illusion. Our results identify a neural connectivity pathway that biases future perception and helps determine mental content.

Abstract

Ongoing fluctuations in neural excitability and in networkwide activity patterns before stimulus onset have been proposed to underlie variability in near-threshold stimulus detection paradigms—that is, whether or not an object is perceived. Here, we investigated the impact of prestimulus neural fluctuations on the content of perception—that is, whether one or another object is perceived. We recorded neural activity with magnetoencephalography (MEG) before and while participants briefly viewed an ambiguous image, the Rubin face/vase illusion, and required them to report their perceived interpretation in each trial. Using multivariate pattern analysis, we showed robust decoding of the perceptual report during the poststimulus period. Applying source localization to the classifier weights suggested early recruitment of primary visual cortex (V1) and ∼160-ms recruitment of the category-sensitive fusiform face area (FFA). These poststimulus effects were accompanied by stronger oscillatory power in the gamma frequency band for face vs. vase reports. In prestimulus intervals, we found no differences in oscillatory power between face vs. vase reports in V1 or in FFA, indicating similar levels of neural excitability. Despite this, we found stronger connectivity between V1 and FFA before face reports for low-frequency oscillations. Specifically, the strength of prestimulus feedback connectivity (i.e., Granger causality) from FFA to V1 predicted not only the category of the upcoming percept but also the strength of poststimulus neural activity associated with the percept. Our work shows that prestimulus network states can help shape future processing in category-sensitive brain regions and in this way bias the content of visual experiences.

More diversity in Flow-land.

I will pass on part of an email from Mr. Todd Denen occasioned by my 8/16/19 post, in which he assures me, that unlike the Flow Genome Project and Flow Collective Research Project discussed in that post, his Flow Research University is legit:

“ My name is Todd Denen and I just came across your post on the FGP guys. I just wanted to say not all Flow training programs are bullshit.....

I'm the founder of the Advanced Flow University which teaches the Flow state from the perspective of the Yogi Flow Experts.

In my book, PEAK PERFORMANCE SECRETS, I reveal the Advanced Flow Techniques which have been used by the Yogi Flow Experts for over 5,000 years. This has allowed them to achieve the highest level of Consciousness, the 7th Level of Flow.

What we see is influenced by what we can do about it

Djebbara et al. do experiments that resolve an ancient debate on the relationship between cognition, movement, and environment, showing that potential actions afforded by an architectural environment influence perception. We perceive the world not as an observer-independent reality but in the mold of potential actions, shaped by the current needs and other personal attributes of the actor–perceiver. I pass on their significance and abstract statements, and then a clip from a description of the work by Gepshtein and Snider.

Significance

Using electroencephalography and virtual reality, our research provides a unique perspective on the centuries-old open-ended debate in cognitive neuroscience and philosophy on the relationship among cognition, movement, and environment. Our results indicate that cortical potentials vary as a function of bodily affordances reflected by the physical environment. First, the results imply that cognition is inherently related to the potential movement of the body; thus, we posit that action is interrelated with perception, actively influencing the perceivable environment. Second, these results indicate that moving in space is to continuously construct a prediction of a world of affordances, suggesting that architects take up the continuity of spaces, given that the unfolding of bodily movement alters perception and experience.

Abstract

Anticipating meaningful actions in the environment is an essential function of the brain. Such predictive mechanisms originate from the motor system and allow for inferring actions from environmental affordances, and the potential to act within a specific environment. Using architecture, we provide a unique perspective on the ongoing debate in cognitive neuroscience and philosophy on whether cognition depends on movement or is decoupled from our physical structure. To investigate cognitive processes associated with architectural affordances, we used a mobile brain/body imaging approach recording brain activity synchronized to head-mounted displays. Participants perceived and acted on virtual transitions ranging from nonpassable to easily passable. We found that early sensory brain activity, on revealing the environment and before actual movement, differed as a function of affordances. In addition, movement through transitions was preceded by a motor-related negative component that also depended on affordances. Our results suggest that potential actions afforded by an environment influence perception.

And, the clip from the review by Gepshtein and Snider:

Djebbara et al. had human participants walking freely while immersed in a virtual environment. A wearable “brain/body imaging setup” included a 64-channel electroencephalographic (EEG) cap that allowed researchers to record the participants’ electrical activity of the brain. The experiment consisted of a series of trials in which participants confronted simulated doors of different widths: Narrow (0.2 m wide), medium (1 m), and wide (1.5 m). At the onset of every trial, the participant was shown 1 of the 3 doors for several seconds. Then the wall framing the door changed its color: To green, prompting the person to pass through the door (the Go condition), or to red, indicating that the person should not approach the door (NoGo). A key result from the analysis of the participants’ brain activity came from the temporal window that just followed the Go/NoGo signal. On average, the part of the brain responsible for processing visual information functioned differently in the Go and NoGo conditions. In the Go condition, brain activity depended significantly on whether the door was passable or not, but in the NoGo condition, no such difference was found.

The authors explain this result by evoking the familiar concept of affordance, introduced by the influential American psychologist James J. Gibson in 1966. Gibson coined the term “affordance” to designate action opportunities offered by objects, trying to find a substitute to the term “value” which he worried would carry “an old burden of philosophical meaning”

A Schism in Flow-land? Flow Genome Project vs. Flow Research Collective

In Nov. 2017 I did a scathing review of  the "Stealing Fire" book by Jamie Wheal and Steven Kotler - in support of expensive workshops offered by their "Flow Genome Project" - purporting to show the latest science relevant to the flow states of enhanced human performance described in Mihaly Csikszentmihalyi’s original writings on this subject. I judged the book a mess, with very little of substance to offer. A follow up post in Sept. 2018 passed on an exchange between one dissatisfied customer and a representative of the flow genome workshops.

Given this background, I can't resist passing on to MindBlog readers an email I just received indicating that there has been trouble in Flow-land... Mr. Kotler and Mr. Wheal have apparently split up and are now present competing websites, both very slick, with Mr. Kotler's (https://www.flowresearchcollective.com) radiating a bit more gravitas than Mr. Wheal's (https://www.flowgenomeproject.com.) Here is the email:

Hey there, 

I work with Steven Kotler who is featured in this article on your site. I have a critical request to change the text and link from Flow Genome Project to Flow Research Collective as this is Steven's new company. 

Currently there is traffic that is being directed from your site to the old company that Steven resigned from and so it's important that we get this updated so that the piece is accurate and up to date. 

We are not requesting that the mention of Flow Genome Project must be withdrawn in relation to Jamie, just that we need it to be clear that Steven is with the Flow Research Collective and that we're directing toward's [sic] that site. 

Please confirm that this is possible. Thanks,

Continuing in the tradition of the "Stealing Fire" book the link in the email "this article on your site" is not to either of the posts I mention above (Nov. 2017, Sept. 2018), but to all the posts done in Nov. and Dec.  of 2017.

I'm not taking the time to look further into this, but would suggest that any potential clients of these expensive purportedly transformational programs do due diligence. CAVEAT EMPTOR!

How weight training changes the brain.

Gretchen Reynolds points to work by Kelty et al. showing that weight training in rats can ameliorate mild cognitive impairment in rats induced by a injecting a lipopolysaccharide known to induce inflammation in the brain, creating a rodent form of mild cognitive impairment or early dementia. The weight training also induces chemical factors that support new nerve cell growth. How do you get rats to train with weights? Get them to climb a ladder for a Froot Loop reward with weights gently taped to their rear ends! Do three workouts a week, increasing the load as in regular resistance training. Similar experiments (inducing mild cognitive impairment) obviously can't be done in humans, but it would be useful to look more at whether and how much weight training in humans might stimulate the appearance of nerve growth factors that support new nerve cell growth. Numerous studies have shown that aerobic exercise has this effect.
