Effects of age on behavioural and eye gaze on Theory of Mind using movie for social cognition.

Evidence has shown that older adults have lower accuracy in Theory of Mind (ToM) tasks compared with young adults, but we are still unclear whether the difficulty in decoding mental states in older adults stems from not looking at the critical areas, and more so from the ageing Asian population. Most ToM studies use static images or short vignettes to measure ToM but these stimuli are dissimilar to everyday social interactions. We investigated this question using a dynamic task that measured both accuracy and error types, and examined the links between accuracy and error types to eye gaze fixation at critical areas (e.g., eyes, mouth, body). A total of 82 participants (38 older, 44 young adults) completed the Movie for the Assessment of Social Cognition (MASC) task on the eye tracker. Results showed that older adults had a lower overall accuracy with more errors in the ipo-ToM (under-mentalising) and no-ToM (lack of mentalisation) conditions compared with young adults. We analysed the eye gaze data using principal components analysis and found that increasing age and looking less at the face were related to lower MASC accuracy in our participants. Our findings suggest that ageing deficits in ToM are linked to a visual attention deficit specific to the perception of socially relevant nonverbal cues.

Not just quantity but also quality of language: Cross-cultural comparisons of maternal mental state talk in New Zealand, Australia, and China.

Western mothers use more mental state talk with children than do Chinese mothers (e.g., "think", "like", "happy"). The present study aimed to examine whether Western mothers not only produced a greater amount of mental state talk, but also used a wider range of mental state terms (i.e., greater lexical variety) compared to Chinese mothers. We compared maternal mental state talk in 271 mother-child dyads from New Zealand, Australia and China, and coded both quantity (i.e., frequency) and quality (i.e., type, variety, valence) of mothers' mental state talk to their 2.5- to 5-year-olds. Western mothers produced more talk about cognitions and emotions, as well as modulations of assertions, but a similar amount of desire talk, compared to Chinese mothers, with the same patterns found in the variety of talk. Western mothers produced an overall higher amount of mental state talk and a greater variety of mental state terms, but crucially, still produced more MS talk after controlling for the variety. Neither the amount nor the variety of maternal MS talk was correlated with children's theory of mind. These findings shed light on the diverse ways that mothers construe and describe mental states in different cultures, and highlight the importance of examining different aspects of maternal mental state talk and their impact on children's theory of mind in future longitudinal studies.

Recognition of facial emotions across the lifespan: 8-year-olds resemble older adults.

On standard emotion recognition tasks with relatively long or unlimited stimuli durations, recognition improves as children grow older, whereas older adults are worse than young adults. Crucially, it was unknown (a) how older adults compare to age groups below young adulthood and (b) whether children can recognize emotions at shorter durations, with short durations likely common in real life. We compared emotion recognition in 5-year-olds, 8-year-olds, young adults and older adults at very brief durations (50 ms, 250 ms) as well as standard unlimited durations. Eight-year-olds were better than 5-year-olds, young adults than all groups, and there was a striking similarity between 8-year-olds and older adults, providing the first clear indication that older adults' recognition abilities are equivalent to that of an 8-year-old at all durations. Emotion recognition was above chance on all emotions and durations among the three older age groups and on most stimuli for 5-year-olds.

Exposure to behavioral regularities in everyday life predicts infants' acquisition of mental state vocabulary.

There are two broad views of children's theory of mind. The mentalist view is that it emerges in infancy and is possibly innate. The minimalist view is that it emerges more gradually in childhood and is heavily dependent on learning. According to minimalism, children initially understand behaviors rather than mental states, and they are assisted in doing so by recognizing repeating patterns in behavior. The regularities in behavior allow them to predict future behaviors, succeed on theory-of-mind tasks, acquire mental state words, and eventually, understand the mental states underlying behavior. The present study provided the first clear evidence for the plausibility of this view by fitting head cameras to 54 infants aged 6 to 25 months, and recording their view of the world in their daily lives. At 6 and 12 months, infants viewed an average of 146.5 repeated behaviors per hour, a rate consistent with approximately 560,000 repetitions in their first year, and with repetitions correlating with children's acquisition of mental state words, even after controlling for their general vocabulary and a range of variables indexing social interaction. We also recorded infants' view of people searching or searching for and retrieving objects. These were 92 times less common and did not correlate with mental state vocabulary. Overall, the findings indicate that repeated behaviors provide a rich source of information for children that would readily allow them to recognize patterns in behavior and help them acquire mental state words, providing the first clear evidence for this claim of minimalism. RESEARCH HIGHLIGHTS: Six- to 25-month-olds wore head cameras to record home life from infants' point-of-view and help adjudicate between nativist and minimalist views of theory-of-mind (ToM). Nativists say ToM is too early developing to enable learning, whereas minimalists say infants learn to predict behaviors from behavior patterns in environment. Consistent with minimalism, infants had an incredibly rich exposure (146.5/h, >560,000 in first year) to repeated behaviors (e.g., drinking from a cup repeatedly). Consistent with minimalism, more repeated behaviors correlated with infants' mental state vocabulary, even after controlling for gender, age, searches witnessed and non-mental state vocabulary.

Left-wing support of authoritarian submission to protect against societal threat.

New Zealand's Prime Minister, Jacinda Ardern, adopted a "go hard, go early" approach to eliminate COVID-19. Although Ardern and her Labour party are considered left-leaning, the policies implemented during the pandemic (e.g., police roadblocks) have the hallmarks of Right-Wing Authoritarianism (RWA). RWA is characterized by three attitudinal clusters (authoritarian aggression, submission, and conventionalism). The uniqueness of the clusters, and whether they react to environmental change, has been debated. Here, in the context of the pandemic, we investigate the relationship between political orientation and RWA. Specifically, we measured political orientation, support for New Zealand's major political parties, and RWA among 1,430 adult community members. A multivariate Bayesian model demonstrated that, in the middle of a pandemic, both left-leaning and right-leaning individuals endorsed items tapping authoritarian submission. In contrast to authoritarian submission, and demonstrating the multidimensional nature of RWA, we observed the typical relationships between political orientation and authoritarian aggression and conventionalism was observed.

Older adults have difficulty decoding emotions from the eyes, whereas easterners have difficulty decoding emotion from the mouth.

Older adults and Easterners have worse emotion recognition (than young adults and Westerners, respectively), but the question of why remains unanswered. Older adults look less at eyes, whereas Easterners look less at mouths, raising the possibility that compelling older adults to look at eyes, and Easterners to look at mouths, might improve recognition. We did this by comparing emotion recognition in 108 young adults and 109 older adults from New Zealand and Singapore in the (a) eyes on their own (b) mouth on its own or (c) full face. Older adults were worse than young adults on 4/6 emotions with the Eyes Only stimuli, but only 1/6 emotions with the Mouth Only stimuli. In contrast, Easterners were worse than Westerners on 6/6 emotions for Mouth Only and Full Face stimuli, but were equal on all six emotions for Eyes Only stimuli. These results provide a substantial leap forward because they point to the precise difficulty for older adults and Easterners. Older adults have more consistent difficulty identifying individual emotions in the eyes compared to the mouth, likely due to declining brain functioning, whereas Easterners have more consistent difficulty identifying emotions from the mouth than the eyes, likely due to inexperience inferring mouth information.

General cognitive decline does not account for older adults' worse emotion recognition and theory of mind.

Older adults have both worse general cognition and worse social cognition. A frequent suggestion is that worse social cognition is due to worse general cognition. However, previous studies have often provided contradictory evidence. The current study examined this issue with a more extensive battery of tasks for both forms of cognition. We gave 47 young and 40 older adults three tasks to assess general cognition (processing speed, working memory, fluid intelligence) and three tasks to assess their social cognition (emotion and theory-of-mind). Older adults did worse on all tasks and there were correlations between general and social cognition. Although working memory and fluid intelligence were unique predictors of performance on the Emotion Photos task and the Eyes task, Age Group was a unique predictor on all three social cognition tasks. Thus, there were relations between the two forms of cognition but older adults continued to do worse than young adults even after accounting for general cognition. We argue that this pattern of results is due to some overlap in brain areas mediating general and social cognition, but also independence, and with a differential rate of decline in brain areas dedicated to general cognition versus social cognition.

Use of a head camera to examine maternal input and its relation to 10- to 26-month-olds' acquisition of mental and non-mental state vocabulary.

We examined the relation between maternal responsiveness and children's acquisition of mental and non-mental state vocabulary in 59 pairs of mothers and children aged 10 to 26 months as they engaged in a free-play episode. Children wore a head camera and responsiveness was defined as maternal talk that commented on the child's actions (e.g., when the child reached for or manipulated an object visible in the head camera). As hypothesized, maternal responsiveness correlated with both mental and non-mental state vocabulary acquisition in younger children (approximately 18 months and younger) but not older children. We posit a diminishing role for maternal responsiveness in language acquisition as children grow older.

Music Making and Neuropsychological Aging: A Review.

Aging is associated with a decline in social understanding and general cognition. Both are integral to wellbeing and rely on similar brain regions. Thus, as the population ages, there is a growing need for knowledge on the types of activities that maintain brain health in older adulthood. Active engagement in music making might be one such activity because it places a demand on brain networks tapping into multisensory integration, learning, reward, and cognition. It has been hypothesized that this demand may promote plasticity in the frontal and temporal lobes by taxing cognitive abilities and, hence, increase resistance to age-related neurodegeneration. We examine research relevant to this hypothesis and note that there is a lack of intervention studies with a well-matched control condition and random assignment. Thus, we discuss potential causal mechanisms underlying training-related neuropsychological changes, and provide suggestions for future research. It is argued that although music training might be a valuable tool for supporting healthy neuropsychological aging and mental wellbeing, well-controlled intervention studies are necessary to provide clear evidence.

The Capricious Nature of Theory of Mind: Does Mental State Understanding Depend on the Characteristics of the Target?

Using a between-groups design and random assignment, this study examined 214 Turkish children's (M = 11.66 years) mindreading and general reasoning about in-group members (Turks), similar out-group members (Syrians within Turkey) and dissimilar out-group members (Northern Europeans). Children heard four mindreading and four general reasoning stories with in-group or out-group members as targets. Whereas children's general reasoning about three groups was equivalent, accuracy of mental state inferences differed by target with more accurate mindreading of in-group targets compared to both sets of out-group targets. In this Turkish sample, mindreading of Syrian targets was the least accurate. Prejudice and perceived realistic threat predicted lower mindreading. These findings have important implications for understanding how similarity and intergroup processes play a role in children's mindreading.

Empathic Accuracy: Worse Recognition by Older Adults and Less Transparency in Older Adult Expressions Compared With Young Adults.

OBJECTIVES: We examined empathic accuracy, comparing young versus older perceivers, and young versus older emoters. Empathic accuracy is related to but distinct from emotion recognition because perceiver judgments of emotion are based, not on what an emoter looks to be feeling, but on what an emoter says s/he is actually feeling. METHOD: Young (≤30 years) and older (≥60 years) adults ("emoters") were unobtrusively videotaped while watching movie clips designed to elicit specific emotional states. The emoter videos were then presented to young and older "perceivers," who were instructed to infer what the emoters were feeling. RESULTS: As predicted, older perceivers' empathic accuracy was less accurate relative to young perceivers. In addition, the emotions of young emoters were considerably easier to read than those of older emoters. There was also some evidence of an own-age advantage in emotion recognition in that older adults had particular difficulty assessing emotion in young faces. DISCUSSION: These findings have important implications for real-world social adjustment, with older adults experiencing a combination of less emotional transparency and worse understanding of emotional experience.

Toddlers' Self-Recognition and Progression From Goal- to Emotion-Based Helping: A Longitudinal Study.

Research has typically used cross-sectional designs to draw conclusions on the development of helping. This study aimed to examine the development of instrumental and empathic helping behaviors as they emerge, and assess how self-recognition might moderate this progression. Seventy-two children (14- to 25-months at T1) were assessed over four monthly sessions. Participants' individual response patterns showed instrumental helping to be a necessary precursor to empathic helping for 55.77%-67.92% of children who helped during the study. Self-recognition emerged before empathic but not instrumental helping, yet did not directly influence helping behavior.

Effects of Age on Emotion Regulation, Emotional Empathy, and Prosocial Behavior.

OBJECTIVES: The degree to which older adults experience emotional empathy and show subsequent prosocial behavior versus experience personal distress in response to another's distress remains unclear. METHOD: Young (n = 40; 17-29 years) and older (n = 39; 61-82 years) adults watched videos of individuals expressing pain or no pain. Pain mimicry was recorded using facial electromyography. Participants were then asked if they would spend the remaining time helping the experimenter. Self-reported tendency to suppress or reappraise emotion was assessed, as well as trait and state emotional empathy and personal distress. RESULTS: Pain mimicry was associated with reduced trait suppression in older adults. In both age groups, greater emotional empathy, averaged across video condition, was associated with increased helping. In addition, relative to young adults, older adults reported more personal distress and emotional reactivity in response to the videos but were just as willing to help. They also put more effort into helping. DISCUSSION: These findings contribute to clarification of mixed previous evidence regarding the experience of emotional empathy in young versus older adulthood. We discuss the importance of considering additional subcomponents of empathy such as emotion regulation, while also accounting for the relevance of the empathy induction to each age group.

Motivation and social-cognitive abilities in older adults: Convergent evidence from self-report measures and cardiovascular reactivity.

Recently, some authors have suggested that age-related impairments in social-cognitive abilities-emotion recognition (ER) and theory of mind (ToM)-may be explained in terms of reduced motivation and effort mobilization in older adults. We examined performance on ER and ToM tasks, as well as corresponding control tasks, experimentally manipulating self-involvement. Sixty-one older adults and 57 young adults were randomly assigned to either a High or Low self-involvement condition. In the first condition, self-involvement was raised by telling participants were told that good task performance was associated with a number of positive, personally relevant social outcomes. Motivation was measured with both subjective (self-report questionnaire) and objective (systolic blood pressure reactivity-SBP-R) indices. Results showed that the self-involvement manipulation did not increase self-reported motivation, SBP-R, or task performance. Further correlation analyses focusing on individual differences in motivation did not reveal any association with performance, in either young or older adults. Notably, we found age-related decline in both ER and ToM, despite older adults having higher motivation than young adults. Overall, the present results were not consistent with previous claims that motivation affects older adults' social-cognitive performance, opening the route to potential alternative explanations.

Lifespan differences in emotional contagion while watching emotion-eliciting videos.

Previous research has examined empathic concern by presenting toddlers with a sad stimulus and examining their emotional response, with the conclusion that toddlers display empathy. Yet, such research has failed to include basic control conditions involving some other aversive stimulus such as white noise. Nor has it compared toddlers to adults to examine potential development in empathy. In the present study, we showed toddlers and adults four video types: infant crying, infant laughing, infant babbling, and a neutral infant accompanied by white noise. We then coded happiness and sadness while viewing the videos, and created a difference score (happiness minus sadness), testing 52 toddlers and 61 adults. Whereas adults showed more sadness towards infant crying than any other stimulus, toddlers' response to crying and white noise was similar. Thus, the toddler response to crying was comparable to previous studies (slight sadness), but was no different to white noise and was significantly reduced relative to adults. As such, toddlers' response seemed to be better characterized as a reaction to an aversive stimulus rather than empathy.

Age-Related Preservation of Trust Following Minor Transgressions.

Objectives: This study assesses age-related differences in the weighting and integration of appearance and behavior cues to trustworthiness. The aim is to assess whether it becomes more difficult with age to detect a cheater in disguise. Method: Young and older adults invested real money in a repeated trust game with trustees who varied on facial expression (smiling, neutral, angry) and return rate (high, low). Trustees were also rated for trustworthiness pre- and post-trust game. Results: Young and older adults learned to disregard appearances to invest more in trustees providing high relative to low returns. Both groups also updated ratings of trustworthiness from pre- to post-trust game in the direction of behavior that was incongruent with appearance. Notably, young (but not older) adults updated ratings of smiling trustees with a high return rate (i.e., returned money on 8 of 10 investments) to reflect reduced trustworthiness in line with the 2 instances of cheating from those trustees. Discussion: The findings show that there are no age-related differences in the way that obvious cheating in disguise is punished with reduced trustworthiness ratings. However, older adults are less vigilant to more subtle cheating in disguise, or are more forgiving of transgressions perceived as minor.

Variety in parental use of "want" relates to subsequent growth in children's theory of mind.

In 2 cross-lagged, longitudinal studies we contrasted parental talk about want in a single context versus multiple contexts. Study 1 examined thirty-two 2 year olds, with mothers describing pictures to children. Mothers could use want in zero, one, or multiple contexts. Children whose mothers used want in multiple contexts experienced a significantly larger gain in mental state terms over a 6-month period. Study 2 examined 50 preschoolers, measuring theory of mind (ToM) with tasks and mental state terms, then had parents intervene by reading booklets in which want was used in 1 or multiple contexts. Over a 6-week period, the latter group made larger gains in ToM. We posit that maternal use of want in multiple contexts assists understanding that want refers to an underlying mental state rather than a single behavior. (PsycINFO Database Record

Music to my ears: Age-related decline in musical and facial emotion recognition.

We investigated young-old differences in emotion recognition using music and face stimuli and tested explanatory hypotheses regarding older adults' typically worse emotion recognition. In Experiment 1, young and older adults labeled emotions in an established set of faces, and in classical piano stimuli that we pilot-tested on other young and older adults. Older adults were worse at detecting anger, sadness, fear, and happiness in music. Performance on the music and face emotion tasks was not correlated for either age group. Because musical expressions of fear were not equated for age groups in the pilot study of Experiment 1, we conducted a second experiment in which we created a novel set of music stimuli that included more accessible musical styles, and which we again pilot-tested on young and older adults. In this pilot study, all musical emotions were identified similarly by young and older adults. In Experiment 2, participants also made age estimations in another set of faces to examine whether potential relations between the face and music emotion tasks would be shared with the age estimation task. Older adults did worse in each of the tasks, and had specific difficulty recognizing happy, sad, peaceful, angry, and fearful music clips. Older adults' difficulties in each of the 3 tasks-music emotion, face emotion, and face age-were not correlated with each other. General cognitive decline did not appear to explain our results as increasing age predicted emotion performance even after fluid IQ was controlled for within the older adult group.

Circulating anti-Müllerian hormone (AMH) associates with the maturity of boys' drawings: Does AMH slow cognitive development in males?

PURPOSE: High levels of circulating anti-Müllerian hormone are unique to developing males, but the function of anti-Müllerian hormone in boys is unknown. In mice, anti-Müllerian hormone contributes to the male biases in the brain, but its receptors are present throughout non-sexually dimorphic portions of the brain. In humans, the speed of maturation is the most overt difference between girls and boys. We postulate that this is because anti-Müllerian hormone slows the maturation of the male human brain. METHODS: One hundred and fourty three 5-year or 6-year-old boys and 38 age-matched girls drew a person and donated a blood sample. The children's drawings were blind-scored to generate a maturity index. The level of anti-Müllerian hormone and the other Sertoli cell hormone, inhibin B, were measured by ELISA. The relationship between the children's age, hormones and maturity index were examined by linear regression analysis. RESULTS: The girls drew more complex and realistic person than the boys (32%, p = 0.001), with their drawings also being larger (39%, p = 0.037) and more coloured-in (235%, p = 0.0005). The maturity index in boys correlated with age (+r = 0.43, p < 0.0005) and anti-Müllerian hormone level (-r = -0.29, p < 0.0005). The association between maturity index and anti-Müllerian hormone level persisted when corrected for age and for inhibin B (r = -0.24, p = 0.0005). The calculated effect of the median level of anti-Müllerian hormone (1 nM) was equal to 0.81 months of development. The size and colouring of the drawings did not correlate with the boys' age, anti-Müllerian hormone or inhibin B. CONCLUSIONS: This exploratory study provides the first indicative evidence that circulating anti-Müllerian hormone may influence the development of the human brain.

What's good for the goose is not good for the gander: Age and gender differences in scanning emotion faces.

OBJECTIVES: Research indicates that older adults' (≥60 years) emotion recognition is worse than that of young adults, young and older men's emotion recognition is worse than that of young and older women (respectively), older adults' looking at mouths compared with eyes is greater than that of young adults. Nevertheless, previous research has not compared older men's and women's looking at emotion faces so the present study had two aims: (a) to examine whether the tendency to look at mouths is stronger amongst older men compared with older women and (b) to examine whether men's mouth looking correlates with better emotion recognition. METHOD: We examined the emotion recognition abilities and spontaneous gaze patterns of young (n = 60) and older (n = 58) males and females as they labelled emotion faces. RESULTS: Older men spontaneously looked more to mouths than older women, and older men's looking at mouths correlated with their emotion recognition, whereas women's looking at eyes correlated with their emotion recognition. DISCUSSION: The findings are discussed in relation to a growing body of research suggesting both age and gender differences in response to emotional stimuli and the differential efficacy of mouth and eyes looking for men and women.
