How theory of mind leads to positive first impressions.

A common conjecture is that social success relies on "theory of mind"-the everyday skill of imputing mental states to others. We test the hypothesis that individuals with stronger theory of mind skills and motivation garner more positive first impressions because of how they interact with others. Participants included 334 young adults who were paired with a peer for a first-time meeting. Dyads completed a cooperative Lego-building task, which was videotaped and later coded for behavioral manifestations of theory of mind by independent raters. Theory of mind accuracy and motivation were assessed with validated laboratory tasks and a self-report questionnaire, respectively. First impressions were assessed based on partner's ratings of participant likeability, enjoyment of the interaction, and changes in positive affect. Results of actor-partner interdependence mediation models revealed that the associations between theory of mind and first impressions are indirect and mediated through behaviors. Specifically, participants with stronger theory of mind demonstrated greater cognitive sensitivity and pragmatic conversational skills. However, only cognitive sensitivity subsequently predicted more favorable first impressions. This research shows that social-cognitive skills can affect others' social impressions through their behavioral manifestations. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

ERP responses to sexual cues among young women attracted to men.

Previous event-related potential (ERP) studies reported larger N170, P3, and late positive potential (LPP) amplitudes to sexual than nonsexual stimuli. These ERPs may not be specifically sensitive to processing sexual cues, however, because the sexual stimuli included information beyond sexual cues (e.g., faces, bodies, social interaction) to a greater extent than comparison stimuli. We investigated ERPs to stimuli that focused on sexual and nonsexual body regions, in different states of readiness for activity, to elucidate neural responses involved in processing sexual cues. Forty cisgender, primarily white, undergraduate women who were attracted to men (Mage  = 18.6, SD = 0.9) viewed images that varied by male body part (penis, arm) and activity state (rest, poised for activity). Participants viewed 40 images per category (flaccid penises, erect penises, outstretched arms, bent arms). Electroencephalography (EEG) was recorded using a 128-channel net, time-locked to the onset of each image. Using a whole-head cluster-mass approach, we found that the P3 was sensitive to sexual readiness-P3 amplitudes were larger to erect than flaccid penises, but not to bent than outstretched arms. The N170 and LPP components did not show evidence of similarly specific responses to sexual readiness, revealing potential dissociation of different neural processes commonly elicited in response to more complex sexual stimuli. An additional novel finding was that an anterior N270-400 was sensitive to sexual readiness. Findings clarify the brain's rapid responses to sexual stimuli, setting the stage for future research aimed at better understanding the neurocognitive processes that contribute to the coordination of sexual arousal.

Event-related potential studies of cross-situational word learning in four-year-old children.

Young children learn word-referent links in cross-situational learning paradigms despite uncertainty as to a given word's correct referent on individual exposures. However, the semantic status of these word-referent links is unknown. Here, we used a novel event-related potential (ERP) testing approach to investigate whether children showed electrophysiological signatures of semantic representations following a typical cross-situational learning paradigm. In Study 1, 20 4-year-old children (mean age: 51.35 months) learned eight new word-object pairs in a cross-situational learning task which included familiar object labeling before training. Then, they completed an ERP task which involved seeing pictures of the novel objects and then hearing words that were either congruent or incongruent with the word-referent association that was trained. Results showed a robust N400 ERP effect, thereby providing evidence for having acquired a semantic representation during the cross-situational learning paradigm. Children also showed good performance on a comprehension test approximately 20 min after training. In a second study, a different sample of 20 4-year-old children (mean age: 52 months) completed the same cross-situational task but without the initial familiar word pretraining. Here, we did not see the N400 effect we saw in Study 1, but children still showed good performance on the delayed comprehension test. We conclude that rapid semantic encoding can occur during cross-situational learning, but that pretraining on the structure of the paradigm may be critical for facilitating that encoding. We speculate on the mechanisms by which pretraining might have effects and discuss the implications of these findings for early word learning.

Theory of mind in dysphoric and non--dysphoric adults: An ERP study of true-- and false--belief reasoning.

Theory of mind (ToM) - the understanding that others' behaviors are connected with internal mental states - is an important part of everyday social cognition. There is increasing behavioral evidence that ToM reasoning can be affected by mood. To gain insight into the ways sad mood may affect the underlying mechanisms of ToM reasoning, we recorded event-related brain potentials (ERPs) as dysphoric (N = 16) and non-dysphoric (N = 24) participants reasoned about a protagonist's true or false beliefs about an object's location. Results showed significant group effects on early components of the ERP - individuals in the dysphoric group showed greater amplitudes for the anterior N1 and N2/P2 components relative to those in the non-dysphoric group. Later in the ERP, non-dysphoric individuals showed evidence of neurocognitive dissociations between true and false belief. Dysphoric individuals, however, did not show evidence for these later dissociations. This evidence suggests that dysphoria may be associated with effortful reasoning about other's mental states, even when that effort is not necessary (i.e., when reasoning about true beliefs). We discuss the implications of these findings for understanding how mood affects ToM reasoning and for how especially deliberative ToM processing in dysphoria may lead to social difficulties.

Multidimensional Reasoning Can Promote 3-Year-Old Children's Performance on the Dimensional Change Card Sort Task.

An important aspect of executive functioning is the ability to flexibly switch between behavioral rules. This study explored how considering the multidimensionality of objects affects behavioral rule switching in 3-year-old children. In Study 1 (N = 40), children who participated in a brief game separating and aggregating an object's dimensions (i.e., color and shape) showed improved performance on the Dimensional Change Card Sort (DCCS), a measure of behavioral rule switching, relative to controls. In Study 2 (N = 80) DCCS performance improved even when the initial practice involved a different dimension (pattern and shape). Thus, practice thinking about multidimensionality can affect 3-year-olds' DCCS performance and therefore may play an important role in the development of flexible thinking.

Inhibitory Control and Preschoolers' Use of Irregular Past Tense Verbs.

We investigated whether children's inhibitory control (IC) is associated with their ability to produce irregular past tense verb forms as well as learn from corrective feedback following overregularization errors. Forty-eight 3;6 to 4;5 year old children were tested on the irregular past tense and provided with adult corrective input via models of correct use or recasts of errors following ungrammatical responses. IC was assessed with a three-item battery of tasks that required suppressing a prepotent response in favor of a non-canonical one. Results showed that IC was associated with children's initial production of irregular forms, but not associated with their post-feedback production. Findings are discussed in terms of current theories of past tense use and acquisition.

Valence in the Reading the Mind in the Eyes task.

The Reading the Mind in the Eyes task (RMET; Baron-Cohen, Wheelwright, Hill, Raste, & Plumb, 2001) is commonly used to assess theory of mind abilities in adults. In the task, participants pair one of four mental state descriptors with a picture of the eye region of a face. The items have varying emotional valence, and nearly 100 studies have examined whether performance on this task varies with item valence. However, efforts to address this question have been hampered by cross-study inconsistencies in how item valence is assessed. Thus, the goal of this study was to establish reference ratings for the valence of RMET items. In Study 1, we recorded valence ratings for each RMET item with a large sample of raters (n = 164). We illustrated how valence categories are essentially arbitrary and largely influenced by sample size. In addition, valence ratings were continuously distributed, further questioning the validity of imposing categorical distinctions. In Study 2, we used an archival dataset to demonstrate how the different categorization schemes resulted in conflicting conclusions about the association between item valence and RMET performance. However, when we examined the association between item valence and performance in a continuous manner, a clear U-shaped pattern emerged: Items that had more extreme valence ratings (negative or positive) were associated with better performance than items with more neutral ratings. We conclude that using the item valence ratings we report, and treating item valence as a continuous rather than categorical predictor, will help bring consistency to the study of the association between item valence and performance in the RMET.

Continuity in the neural system supporting children's theory of mind development: Longitudinal links between task-independent EEG and task-dependent fMRI.

Children's explicit theory of mind (ToM) understandings change over early childhood. We examined whether there is longitudinal stability in the neurobiological bases of ToM across this time period. A previous study found that source-localized resting EEG alpha attributable to the dorsal medial prefrontal cortex (DMPFC) and right temporoparietal junction (RTPJ) was associated with children's performance on a battery of theory of mind tasks. Here, we investigated a small subset of children (N = 12) in that original study as a preliminary investigation of whether behavioral measures of ToM performance, and/or EEG localized to the DMPFC or RTPJ predicted ToM-specific fMRI responses 3.5 years later. Results showed that preschoolers' behavioral ToM-performance positively predicted later ToM-specific fMRI responses in the DMPFC. Preschoolers' resting EEG attributable to the DMPFC also predicted later ToM-specific fMRI responses in the DMPFC. Given the small sample, results represent a first exploration and require replication. Intriguingly, they suggest that early maturation of the area of the DMPFC related to ToM reasoning is positively linked with its specific recruitment for ToM reasoning later in development, affording implications for characterizing conceptual ToM development, and its underlying neural supports.

Childhood emotional abuse, physical abuse, and neglect are associated with theory of mind decoding accuracy in young adults with depression.

The current study is the first to examine the relation of childhood abuse and neglect history to theory of mind decoding accuracy as moderated by depression. Fifty-five young adults with current or lifetime unipolar depression diagnosis and 70 never-depressed young adults completed the 'Reading the Mind in the Eyes task,' (RMET). Childhood emotional abuse, physical abuse, and neglect were assessed with a gold-standard contextual interview with standardized, independent ratings. Poorer RMET accuracy was associated with a history of emotional abuse in the depressed group and a history of physical abuse in the non-depressed group. In contrast, across both groups, those with a history of neglect showed significantly enhanced theory of mind decoding accuracy compared to those without. Further, differential accuracy across positive, negative, and neutral valenced stimuli in the RMET was observed in each model. These findings indicate that distinct theory of mind performance results from early experiences of threat versus deprivation, and suggest that early intervention may be most successful in preventing negative interpersonal outcomes of maltreatment by focusing on remediating theory of mind deficits resulting from abuse, and tempering heightened sensitivity in those exposed to neglect.

Children remember words from ignorant speakers but do not attach meaning: evidence from event-related potentials.

Although we know much about the conditions under which children demonstrate selective social learning, we have a limited understanding of the cognitive mechanisms by which children's selectivity manifests. Here, we report findings from a brain electrophysiological (ERP) study designed to determine the extent to which words presented by ignorant speakers were later both familiar to children and associated with semantic meaning. Forty-eight children (mean age = 6.5 years) first experienced novel word training from either a knowledgeable or an ignorant speaker. Children's ERPs were subsequently recorded as they heard a recording of the speaker using the novel word, followed by a picture of either the object the word was paired with during training (congruent) or a distractor object that was also present during training (incongruent). Children trained by a knowledgeable speaker showed both N200 and N400 effects to the incongruent word-referent pairings, thereby suggesting that the novel words were both familiar and bore a semantic association. In contrast, children trained by an ignorant speaker demonstrated only the N200 effect, thereby suggesting that the word-referent links were familiar, but not associated with semantic meaning. These findings provide evidence that selective word learning involves the disruption of processes specifically associated with semantic consolidation of word learning events.

Conceptual constraints and mechanisms in children's selective learning.

Although we can support Heyes' call for more research on mechanisms, we disagree that the problem has been ignored as Heyes suggests. We also doubt that basic learning mechanisms are alone sufficient to account for the broad range of findings in the selective social learning literature. Although phylogenetically shared learning mechanisms must support selective social learning, we believe that they must also be guided by top-down conceptual considerations that may be special to humans. Research to date has been focused on establishing the boundary conditions on selective social learning, with the goal of making generalizations that will constrain theorizing about the character of that special knowledge. This is critical to our understanding of both why and how selective social learning manifests in children.

Serotonin and Dopamine Gene Variation and Theory of Mind Decoding Accuracy in Major Depression: A Preliminary Investigation.

Theory of mind-the ability to decode and reason about others' mental states-is a universal human skill and forms the basis of social cognition. Theory of mind accuracy is impaired in clinical conditions evidencing social impairment, including major depressive disorder. The current study is a preliminary investigation of the association of polymorphisms of the serotonin transporter (SLC6A4), dopamine transporter (DAT1), dopamine receptor D4 (DRD4), and catechol-O-methyl transferase (COMT) genes with theory of mind decoding in a sample of adults with major depression. Ninety-six young adults (38 depressed, 58 non-depressed) completed the 'Reading the Mind in the Eyes task' and a non-mentalistic control task. Genetic associations were only found for the depressed group. Specifically, superior accuracy in decoding mental states of a positive valence was seen in those homozygous for the long allele of the serotonin transporter gene, 9-allele carriers of DAT1, and long-allele carriers of DRD4. In contrast, superior accuracy in decoding mental states of a negative valence was seen in short-allele carriers of the serotonin transporter gene and 10/10 homozygotes of DAT1. Results are discussed in terms of their implications for integrating social cognitive and neurobiological models of etiology in major depression.

The Children's Social Understanding Scale: construction and validation of a parent-report measure for assessing individual differences in children's theories of mind.

Children's theory of mind (ToM) is typically measured with laboratory assessments of performance. Although these measures have generated a wealth of informative data concerning developmental progressions in ToM, they may be less useful as the sole source of information about individual differences in ToM and their relation to other facets of development. In the current research, we aimed to expand the repertoire of methods available for measuring ToM by developing and validating a parent-report ToM measure: the Children's Social Understanding Scale (CSUS). We present 3 studies assessing the psychometric properties of the CSUS. Study 1 describes item analysis, internal consistency, test-retest reliability, and relation of the scale to children's performance on laboratory ToM tasks. Study 2 presents cross-validation data for the scale in a different sample of preschool children with a different set of ToM tasks. Study 3 presents further validation data for the scale with a slightly older age group and a more advanced ToM task, while controlling for several other relevant cognitive abilities. The findings indicate that the CSUS is a reliable and valid measure of individual differences in children's ToM that may be of great value as a complement to standard ToM tasks in many different research contexts.

Developmental differences in the structure of executive function in middle childhood and adolescence.

Although it has been argued that the structure of executive function (EF) may change developmentally, there is little empirical research to examine this view in middle childhood and adolescence. The main objective of this study was to examine developmental changes in the component structure of EF in a large sample (N = 457) of 7-15 year olds. Participants completed batteries of tasks that measured three components of EF: updating working memory (UWM), inhibition, and shifting. Confirmatory factor analysis (CFA) was used to test five alternative models in 7-9 year olds, 10-12 year olds, and 13-15 year olds. The results of CFA showed that a single-factor EF model best explained EF performance in 7-9-year-old and 10-12-year-old groups, namely unitary EF, though this single factor explained different amounts of variance at these two ages. In contrast, a three-factor model that included UWM, inhibition, and shifting best accounted for the data from 13-15 year olds, namely diverse EF. In sum, during middle childhood, putative measures of UWM, inhibition, and shifting may rely on similar underlying cognitive processes. Importantly, our findings suggest that developmental dissociations in these three EF components do not emerge until children transition into adolescence. These findings provided empirical evidence for the development of EF structure which progressed from unity to diversity during middle childhood and adolescence.

Selective social learning: new perspectives on learning from others.

This special issue was motivated by the recent, wide-ranging interest in the development of children's selective social learning. Human beings have a far-reaching dependence on others for information, and the focus of this issue is on the processes by which children selectively and intelligently learn from others. It showcases some of the finest current work in this area and also aims to encourage new lines of investigation and new ways of thinking about how children learn from others. This issue also serves to highlight this new direction in basic research for the broader community of researchers, educators, and practitioners. Research on issues related to the facilitation of social learning has clear relevance to early educational contexts. In addition, by bringing together a varied pool of research on the same general topic, developmental scientists can discern the consistencies and themes that emerge from their collective efforts. The work presented here illustrates the breadth of children's selectivity across ages and domains of development, and it highlights the growing range of methods that can be recruited to investigate selectivity. This new research leads the field to reconsider the various ways in which social information guides learning and calls for novel theoretical accounts of these developments.

Preschoolers' selective learning is guided by the principle of relevance.

We investigate whether preschoolers' word learning is selectively attuned to learning word-referent links that they expect will be relevant to their everyday communicative contexts. In two studies, 4-year-olds were taught the name of an unfamiliar toy that they were told was purchased either nearby or faraway. Children's memory for the link was assessed either by a speaker who was not present when it was taught or by the same speaker who taught it to them. Children who were told that the toys were from nearby learned the word-referent link, whereas children who were told the toys were from faraway did not. Our findings suggest that 4-year-olds' word learning is "attuned to relevance" - they selectively acquire new word meanings that will have communicative utility in their linguistic community. These findings provide the first evidence that children's selective word learning is driven by an overarching principle of prospective relevance.

Individual differences in executive functioning predict preschoolers' improvement from theory-of-mind training.

Twenty-four 3.5-year-old children who initially showed poor performance on false-belief tasks participated in a training protocol designed to promote performance on these tasks. Our aim was to determine whether the extent to which children benefited from training was predicted by their performance on a battery of executive functioning tasks. Findings indicated that individual differences in executive functioning performance strongly and consistently predicted improvement in children's false-belief performance and their ability to appropriately explain false-belief-based behavior, both during the training period and during the posttest. These findings were robust after statistically controlling for several relevant covariates. These results are consistent with the suggestion that executive functioning skills promote developments in theory of mind by facilitating the ability to reflect upon and learn from relevant experience.

Dopamine receptor D4 gene variation predicts preschoolers' developing theory of mind.

Individual differences in preschoolers' understanding that human action is caused by internal mental states, or representational theory of mind (RTM), are heritable, as are developmental disorders such as autism in which RTM is particularly impaired. We investigated whether polymorphisms of genes affecting dopamine (DA) utilization and metabolism constitute part of the molecular basis of this heritability. Seventy-three 42- to 54-month-olds were given a battery of RTM tasks along with other task batteries that measured executive functioning and representational understanding more generally. Polymorphisms of the dopamine D4 receptor gene (DRD4) were associated with RTM performance such that preschoolers with shorter alleles outperformed those with one or more longer alleles. However, polymorphisms of the catechol-O-methyl transferase gene (COMT) and the dopamine transporter gene (DAT1) genes were not associated with children's RTM performance. Further tests showed that the association between DRD4 allele length and RTM performance was not attributable to a common association with executive functioning or representational understanding more generally. We conclude that DRD4 receptors, likely via their effects on frontal lobe development and functioning, may represent a neuromaturational constraint governing the stereotypical and universal trajectory of RTM development.

Learning foreign labels from a foreign speaker: the role of (limited) exposure to a second language.

Three- and four-year-olds (N = 144) were introduced to novel labels by an English speaker and a foreign speaker (of Nordish, a made-up language), and were asked to endorse one of the speaker's labels. Monolingual English-speaking children were compared to bilingual children and English-speaking children who were regularly exposed to a language other than English. All children tended to endorse the English speaker's labels when asked 'What do you call this?', but when asked 'What do you call this in Nordish?', children with exposure to a second language were more likely to endorse the foreign label than monolingual and bilingual children. The findings suggest that, at this age, exposure to, but not necessarily immersion in, more than one language may promote the ability to learn foreign words from a foreign speaker.

For love or money? What motivates people to know the minds of others?

Mood affects social cognition and "theory of mind", such that people in a persistent negative mood (i.e., dysphoria) have enhanced abilities at making subtle judgements about others' mental states. Theorists have argued that this hypersensitivity to subtle social cues may have adaptive significance in terms of solving interpersonal problems and/or minimising social risk. We tested whether increasing the social salience of a theory of mind task would preferentially increase dyspshoric individuals' performance on the task. Forty-four dysphoric and 51 non-dysphoric undergraduate women participated in a theory of mind decoding task following one of three motivational manipulations: (i) social motivation (ii) monetary motivation, or (iii) no motivation. Social motivation was associated with the greatest accuracy of mental state decoding for the dysphoric group, whereas the non-dysphoric group showed the highest accuracy in the monetary motivation condition. These results suggest that dysphoric individuals may be especially, and preferentially, motivated to understand the mental states of others.
