Q & A with Shanna van Trigt, Vrije Universiteit author of “Autistic Traits and Self-Conscious Emotions in Early Childhood” Child Development

Peer-Reviewed Publication

SOCIETY FOR RESEARCH IN CHILD DEVELOPMENT

Research shows that given the difficulties in navigating social relationships, children with more autistic traits might be prone to less attuned self-conscious emotions after transgression (displaying less guilt and embarrassment and more shame). A new study released in Child Development by researchers at Vrije Universiteit and the University of Amsterdam investigated for the first time the association between autistic traits and self-conscious emotions of guilt, embarrassment, and shame in young children. 

Researchers also further examined whether children with more autistic traits experience these non-attuned self-conscious emotions due to lower levels of Theory of Mind (i.e., ability to understand and reason about people’s mental states, including beliefs), which was not the case. The findings provided initial evidence that children with more autistic traits do not show less guilt and embarrassment, but they show increased shame-like avoidance), which could hinder their reparation of social relationships after transgressions. 

The Society for Research in Child Development (SRCD) had the opportunity to chat with lead author Shanna van Trigt about this important research.

SRCD: In your opinion, why is this the first time the association between autistic traits and self-conscious emotions were investigated? 

van Trigt: The association between autistic traits and self-conscious emotions has been investigated in older children and adolescents. However, this is the first time these associations were investigated in early childhood. One reason may be that, traditionally, it has been assumed that self-conscious emotions develop only later in childhood. However, more recent research shows that very young children can display rudimentary forms of self-conscious emotions, too. Another reason may be that although research on emotions is rapidly growing, most of this research examines the so-called basic emotions and much less is known about more complex self-conscious emotions. 

SRCD: Describe your hypothesis.

van Trigt: We hypothesized that young children with more autistic traits would show less guilt, less embarrassment, and more shame-like avoidance after accidentally harming another person (i.e., breaking their “favorite” toy), and that these associations would be partially explained by lower Theory of Mind. 

SRCD: Your work showed that children with more autistic traits have lower Theory of Mind and show more shame-like avoidance after a transgression in early childhood.  Expand on why this is important.

van Trigt: Shame is known to hinder the repairment of social relationships after a transgression, making it difficult for children with higher levels of autistic traits to engage with others and feel socially connected after transgressions. It is important to note that although autistic traits were related to lower Theory of Mind, this did not explain the higher levels of shame-like avoidance after transgression in our study. Children with more autistic traits seem not to show any deficits in the Theory of Mind ability that matters most for the experience of self-conscious emotions-the understanding of emotions. They show lower understanding of others’ (false) beliefs, which, importantly, did not seem to play a role in the experience of self-conscious emotions. This is why we think that the social skills training focusing on enhancing socio-cognitive skills in autism may not necessarily bring about improvements in emotional experiences and wellbeing.

SRCD: What are some implications of your research for early interventions for children with autistic traits?

Van Trigt: Our results imply that deficits in Theory of Mind, although related to more autistic traits, may not predict less attuned self-conscious emotions, at least not yet in early childhood. Previous intervention studies found that interventions for autism that focus on Theory of Mind and related socio-cognitive skills, improve socio-cognitive skills, but fail to result in wider improvements in real-life social behavior. As Theory of Mind skills do not necessarily relate to non-attuned self-conscious emotions that children with high levels of autistic traits may experience in a wide range of social situations, support efforts focusing on the regulation of self-conscious emotions may need to focus on targeting these emotions directly. For example, in the case of frequent and intense shame experiences, enhancing (self-) compassion with mindfulness interventions may be a useful option helping young children with high levels of autistic traits to regulate these emotions, thereby increasing their wellbeing and the quality of relationships with others.

SRCD: What were the limitations in your research?

van Trigt: Our study has several limitations that warrant attention when interpreting our results. First, we had a community sample of children, and we measured autistic traits with parents’ reports. Future studies may involve young children on the autism spectrum to investigate whether autism may be related to non-attuned self-conscious emotions, too. Our families came from the Netherlands – a Western country and parents were relatively highly educated. This prevents us from generalizing our results to different cultures and to families with lower socio-economic status. Also, our study was cross-sectional, which does not allow drawing any causal conclusions, for example, our mediation analyses to assess the role of Theory of Mind do not prove temporal ordering or causality. Longitudinal studies may be useful in the future to uncover bidirectional effects between autistic traits and self-conscious emotions over time.

SRCD: What are your recommendations on future work in this area? 

van Trigt: Future studies may build on our findings by inspecting the development of self-conscious emotions in children with more autistic traits from early to late childhood in a longitudinal study. Moreover, mechanisms explaining the relationship between autistic traits and self-conscious emotions other than Theory of Mind can be investigated. For example, communication deficits or elevated levels of social anxiety may play a role in less attuned self-conscious emotions in children with more autistic traits. Also, investigating these associations in young children on the autism spectrum can tell us if our findings translate to autism as well.

SRCD: If you could offer one quote or takeaway about the research, what might that be? 

van Trigt: Children with more autistic traits may show disturbances in some, but not all, self-conscious emotions after transgression, which could hinder their social engagement and the feeling of connection to others. Therefore, new support strategies to regulate self-conscious emotions through enhancing (self-)compassion, such as mindfulness interventions, may be considered when targeting young children with more autistic traits.

Doctors more extroverted, but also more neurotic and less open than patients: Study

Character trait differences might have clinical implications for doctor-patient relationships

Peer-Reviewed Publication

BMJ

Doctors are more extroverted, agreeable, and conscientious, but also more neurotic and less open than their patients, finds an analysis of responses to two nationally representative Australian surveys, published online in the open access journal BMJ Open.

These character trait differences might have clinical implications for the doctor-patient relationship, suggest the researchers. 

The selection and training of doctors may accentuate personality characteristics that differ from their patients, say the researchers, adding that, in turn, these differences may create a mismatch between how doctors deliver information and how patients receive it.

The available body of research on doctors’ personality is dominated by convenience samples, low sample sizes and response rates, and limited by a focus on specific types of doctors, medical schools, or geographic areas, point out the researchers.

To avoid these issues, the researchers drew on two nationally representative Australian surveys, in which respondents were asked to assess their own personality traits.

The Household, Income and Labour Dynamics in Australia (HILDA) survey of 25,358 members of the general public aged 20-85 included 18,705 patients, 1261 highly educated people, and 5814 professional carers.

The Medicine in Australia: Balancing Employment and Life (MABEL) survey of 19,351 doctors included 5844 general practitioners, 1776 patient-oriented specialists, and 3245 ‘technique-oriented’ specialists.

The researchers wanted to find out if there were personality trait differences between doctors and all the other groups, and if there might be equivalent differences between the two groups of medical specialists.

They focused on the ‘big 5’ personality traits of conscientiousness, agreeableness, extroversion, neuroticism, and openness as well as locus of control—belief in personal agency (internal) rather than external forces, such as fate, a higher power, or powerful others (external). 

Agreeableness encapsulates empathy, kindness, cooperation, and warmth; conscientious includes the descriptors orderly, systematic, efficient, careful, and organised; extroverts are talkative, confident, loud, bold and lively; neurotics describe themselves as envious, moody, touchy, jealous, temperamental and fretful; while the descriptors philosophical, creative, intellectual, complex, and imaginative apply to openness.

Not unexpectedly, doctors were more agreeable and extroverted than all the other groups, but they were also more neurotic. And both doctors and caring professionals were more agreeable than patients. But doctors were significantly more agreeable than caring professionals.

Somewhat unexpectedly, doctors more strongly believed themselves subject to external forces beyond their control than the general public. Although significant, this difference was relatively small, and there were no significant differences between doctors and patients, caring professionals, or the highly educated, caution the researchers.

Finally, differences among doctors across medical specialties were, overall, smaller than those between doctors and patients and the public, with family doctors (GPs) standing out for their higher level of agreeableness.

Women doctors seemed to differ more strongly from the other groups relative to men, the survey responses suggested. This was particularly noticeable for neuroticism, with women doctors scoring significantly higher on this trait than female members of the general public.

The researchers acknowledge certain limitations to their findings. Although based on well known and validated instruments, the scales used to assess personality traits were self-rated. And the ‘big 5’ descriptors differed slightly between the two surveys. 

Nevertheless, the researchers suggest that these personality differences might have implications for the doctor-patient relationship and ultimately the success of treatment.

“For example, being more conscientious has implications for treatment adherence as conscientious doctors may overestimate their patients’ ability to follow recommendations. Higher doctor neuroticism, which is related to stress, could lead doctors to see stress as a normal part of life, and, thus, underestimate the impact of [it] on patient wellbeing,” they write. 

“Doctor agreeableness and conscientiousness increase patient satisfaction with care, but could potentially lead doctors to view patients—in contrast to themselves—as more confrontational and less conscientious than patients actually are, causing an asymmetry in doctor and patient judgements of one another, which could impact outcomes,” they add.

“By taking into account these differences, doctors can better calibrate their judgments of patients and gain insight into factors that influence their patient interactions,” they suggest. 

And a range of different personalities is also likely to be better for clinical team performance, they add. “The lack of personality difference we found between doctor specialties suggests that adding more doctors to a team will not increase diversity of personality-base perspectives. However, the differences found between doctors and those in other caring professions suggest that including non-doctor caring professionals in clinical teams will increase personality diversity and, thus, team performance.” 

Better social drinkers don’t earn more

Alcohol-tolerant men in East Asia don’t financially benefit over their intolerant colleagues

Peer-Reviewed Publication

UNIVERSITY OF TOKYO

Social drinking after work is traditionally seen as an important way to build relationships in East Asia. There’s sometimes even a fear that missing out could leave you on the back foot when climbing the career ladder. However, a joint paper looking at the drinking habits and economic situation of working men in Japan, Taiwan and South Korea has found that those who can drink more do not seem to have a financial leg-up over their alcohol-intolerant and less-drinking colleagues. As almost half of the population in East Asia has some intolerance to alcohol, and with the growth of the sober-curious lifestyle, this result may come as good news to those who don’t want to have to drink to get ahead.

Have you ever felt pressured to join an afterwork drinking party, even if you’re more inclined to having some tea than getting tipsy? In East Asia, drinking with your colleagues is traditionally seen as an almost essential part of the working culture. Drinking parties are used to build trust, get closer to your boss or subordinates, and discuss topics more candidly than in the workplace. However, a joint study between researchers in Japan, Taiwan and South Korea appears to show that those who drink more don’t necessarily reap extra financial benefits at work, compared to those who drink less.

“We found no justification for drinking for the purpose of improving labor market outcomes,” said Professor Daiji Kawaguchi, an economist from the Graduate School of Public Policy at the University of Tokyo. “Despite the widespread perception that drinking is important for business communication in East Asia, we did not find evidence supporting the idea. Health research has already found that there is no benefit of heavy alcohol consumption in terms of improving health outcomes, so I think this is important knowledge for when a person decides to drink or not.”

The team surveyed working men aged 25 to 59 years old with a list of 45 questions, including ones on health, drinking habits, finances and weekly working hours. Respondents also self-checked their alcohol tolerance using a simple stick-on alcohol patch test. In total, about 3,500 men from across the three regions participated. The researchers were particularly interested in Asian men not only because of the work-related drinking culture, but also because of alcohol flush, or “Asian flush,” syndrome (AFS), which causes people’s faces to turn red while they also quickly experience headaches, sickness and other symptoms due to a genetic inability to digest alcohol.

“We wanted to find out if a wage premium existed for those with a higher alcohol tolerance,” explained Kawaguchi. “Although our results showed that alcohol-tolerant men do drink more often and more each time than alcohol-intolerant men, there was no significant difference across the three populations in terms of working hours or earnings between them.” About 52% of the respondents in Japan and Taiwan and about 60% in South Korea were alcohol intolerant, which the researchers say is in line with figures reported in medical literature.

A limitation of the study was that the South Korean sample size was smaller (around 500 people, compared to 1,000 from Taiwan and 2,000 from Japan), restricted to the capital city of Seoul, and included a disproportionate number of college-educated respondents (92%) compared to the national educational average. “We would like to do a similar analysis again,” said Kawaguchi, “but next time with a much larger data set and in collaboration with other specialists, to look in more detail at genome bank data and alcohol digestive ability in combination with socioeconomic outcomes.”  

With a general trend in young people from high-income countries towards drinking less — which in 2022 led Japan’s National Tax Agency to even encourage the country’s youth to drink more (due to declining tax revenues) — this result will hopefully come as good news that you don’t have to get drinking to get ahead. “I enjoy social drinking despite my intolerance to alcohol,” Kawaguchi said. “However, no one should be pressured to drink.”

Long-term research on chimpanzees offers new clues to the puzzle of personality

DURHAM, N.C. -- Throw a tantrum. Threaten, shove aside or steal from your colleagues. Science confirms, yet again, that brutish behavior can be an effective path to power. And not just in humans, but in chimpanzees, too. 

A new study appearing April 24 in the journal PeerJ Life and Environment found that male chimps with more bullying, greedy and irritable personalities reached higher rungs of the social ladder and were more successful at siring offspring than their more deferential and conscientious counterparts.

But if that’s the case, researchers ask, why isn’t every chimp a bully? 

A team led by researchers at the University of Edinburgh and Duke University followed 28 male chimps living in Gombe National Park in Tanzania.

previous study of Gombe chimpanzees led by Edinburgh’s Alexander Weiss along with Duke professor Anne Pusey and colleagues showed how some chimpanzees are more sociable, while others are loners. Some lean towards easy-going, while others are more overbearing or quick to pick fights.

Tanzanian field researchers who knew the chimpanzees well performed the personality assessments, based on years of near-daily observations of how each chimpanzee behaved and interacted with other chimps.

In the current study, researchers found that male chimps with certain personality traits -- in this case, a combination of high dominance and low conscientiousness -- tend to fare better in life than others. 

“Personality matters,” said Joseph Feldblum, assistant research professor of evolutionary anthropology at Duke and the other lead author of the study.

It may not be shocking to learn that bullying has its perks. But for some researchers, findings like these pose a conundrum: If males with certain personality tendencies are more likely to rise to the top and reproduce, and pass the genes for those traits on to their offspring, then shouldn’t every male be that way? 

In other words, why do personality differences exist at all?

“It’s an evolutionary puzzle,” Feldblum said.

One long-held theory is that different personality traits pay off at different points in animals’ lives. Even if being aggressive gives young male chimps an edge, it might backfire when they’re older. Or perhaps certain traits are a liability in youth but an asset in old age.

“Think of the personality traits that lead some people to peak in high school versus later in life,” Weiss said. “It’s a trade-off.” 

But when the team tested this idea, using 37 years of data going back to some of Jane Goodall’s early work at Gombe in the 1970s, they found the same personality traits were linked to high rank and reproductive success across the lifespan. 

The findings suggest that something else must explain the diversity of personalities in chimpanzees. It might be that the “best” personality to have varies depending on environmental or social conditions, or that a trait that is beneficial to males is costly to females, Feldblum said.

If that were true, then “genes associated with those traits would be kept in the population,” Weiss said.

Not too many years ago, the mere suggestion that animals have personalities at all was considered taboo. Jane Goodall herself was accused of anthropomorphism when she described some of the Gombe chimpanzees as “bolder” or “more fearful” than others, some as “affectionate” and others “cold.”

Since that time, scientists studying creatures ranging from birds to squid have found evidence of distinctive personalities in animals: quirks and idiosyncrasies and ways of relating to the world that remain reasonably stable over time and across situations.

Weiss says personality ratings for animals have proven to be as consistent from one observer to the next as are similar measures of human personality.

“The data just don’t support the skepticism,” Weiss said.

In Japan, many municipalities have suffered from population decline due to low birth rates and an aging population. In 2022, the Japanese population over the age of 65 was 36.21 million, accounting for 28.9% of the total population. In addition, approximately 1,300 shrinking cities are within the 1,700 municipalities in Japan. Moreover, the large number of shrinking cities in Japan is unprecedented on a global scale. As a response to the low birthrate, the Japanese government is discussing “unprecedented” measures to reverse the decline, such as providing financial assistance for education to families with young children.

Assistant Professor Haruka Kato, at the Graduate School of Human Life and Ecology, Osaka Metropolitan University, clarified the effectiveness of increasing educational support for children in preventing population decline. In detail, the study employed Bayesian network analysis, a technique for machine learning, using a dataset of economic, social, and educational indicators. The dataset consists of cross-sectional data from 259 indicators of approximately 1,300 shrinking cities, representing the majority of city-level government statistics in Japan.

In conclusion, this study demonstrates that social and educational indicators strongly affect the population decline rate. This implies that municipalities that invest more in education for children tend to have lower population decline rates. Surprisingly, educational indicators exert a greater influence than economic indicators, such as the financial strength index. The indicators include the “number of children per teacher in elementary school” and the “number of students per educational computer in schools.”

According to Professor Kato, “This relevance of educational indicators might be unique to Japan, which has experienced a declining population due to its low birthrates. Education accounts for a low percentage of national and administrative fiscal expenditures in Japan, primarily because social welfare expenditures for older adults are a heavy burden. However, among the fiscal expenditure limitations in Japan, the suggestion is that increasing investment in education for children might help solve the problem of shrinking cities. In addition, the conclusion would be effective in some Asian countries, such as South Korea and China, which will decline in population due to low birth rates and aging populations.”

The results were published in PLOS ONE.
