Social cognition and the human brain

Humans are exceedingly social animals, but the neural underpinnings of social cognition and behavior are not well understood. Studies in humans and other primates have pointed to several structures that play a key role in guiding social behaviors: the amygdala, ventromedial frontal cortices, and right somatosensory-related cortex, among others. These structures appear to mediate between perceptual representations of socially relevant stimuli, such as the sight of conspecifics, and retrieval of knowledge (or elicitation of behaviors) that such stimuli can trigger. Current debates concern the extent to which social cognition draws upon processing specialized for social information, and the relative contributions made to social cognition by innate and acquired knowledge.     

Facial experience during the first year

Parents of 2-, 5-, 8-, and 11-month-olds used two scales we developed to provide information about their infants' facial experience with familiar and unfamiliar individuals during one week. Results showed large discrepancies in the race, sex, and age of faces that infants experience during their first year with the majority of their facial experience being with their primary caregiver, females, and other individuals of the same-race and age as their primary caregiver. The infant's age and an unfamiliar individual's sex were predictive of their time spent interacting with one another. Moreover, an unfamiliar individual's sex was predictive of the attention infants allocated during social interactions. Differences in frequency and length of interactions with certain types of faces, as well as in infant attention toward certain individuals, all likely contribute to the development of expertise in processing commonly experienced face types and deficiencies in processing less commonly experienced face types.     

Social cognition and the development of rule-guided behaviour

The weak to modest relationship between cognitive measures of judgement and reasoning and children's behaviour has led to a search for more satisfactory predictors of behaviour. One proposal is to integrate cognitive-developmental theory with children's perceptions of the self and others. In this regard, cross-sectional and longitudinal evidence indicates that children's “identification” as expressed by self-reports of parents' attractiveness and similarity to the self is correlated with their rule-guided behaviour. These relationships reflect the effects of sex-typing. In a study of behaviour in a naturalistic setting, Grade 1 girls' identification with the mother was correlated with a resistance to others' ruleviolations in Grade 2. Boys' self-initiated violations in Grade 2 were correlated with father identification in Grade 3. Given that behaviour can be mediated by perceptions of parents in relation to the self, and that effective socialization may reflect perceptions of control and a willingness to obey, a study of children's evaluations of maternal discipline techniques is reported. Findings were that children of all ages prefer an authoritative parent who displays firmness and flexibility in dealing with the situation at hand. The implications for theories of social development are discussed. Bidirectional influences in parent-child relations are considered as well as age-related changes in the connection between behaviour and sources of perceived control. Processes by which perceptions of control form a basis for autonomy and responsibility are examined.     

The development of referential offering in the first year

The ontogeny of referential offers was examined in a longitudinal, within dyad case study of two mother–infant pairs. A combination of microanalytic and qualitative methodologies was employed in describing the functions and morphology of this gesture, as well as its temporal and sequential organization with a number of infant and maternal behaviours. Offers were found to emerge from repetitive, exploratory play routines that provide infants with alternative visual perspectives on objects, and were facilitated by mothers' support of infants' immature attentional, motoric and arousal regulation capacities. Offers were observed to co. occur with maternal behaviours that direct and maintain infants' attention to objects. Our observations suggest that offers are transformed through guided interactions into conventional communicative gestures. Offering arises as mothers become part of the infants' exploratory play routines, gradually changing the function of the behaviour of the infants. These observations are consistent with dynamic systems models of development.     

Social cognition and aggression in delinquent adolescent males

The relationship of aggression to several social cognitive variables in delinquent adolescent males was investigated. Subjects were fifty-eight institutionalized males identified by peers as high-aggressive or low-aggressive. Participants were administered measures of perspective taking, moral judgment, and person perception. The findings indicated that only perspective-taking ability was significantly related to aggressive behavior in delinquents. High-aggressive delinquents were less able to perceive others' viewpoints than were low-aggressive delinquents. These findings are consistent with previous research concerning perspective taking and aggression, but disconfirm research involving other social cognitive variables and aggression. Results further indicate the importance of studying social cognitive variables as they relate to relevant clinical behaviors.     

Native-language sensitivities: evolution in the first year of life

In the first few months of their lives, human infants can perceive differences in phonetic contrasts not present in their environment and that their parents cannot discriminate. At 12 months, their pattern of discrimination approaches that of their parents. Until recently, it was believed that the perception of native-language categories did not significantly evolve in that period. Kuhl et al. offer compelling new evidence indicating significant increase in native-language perception.     

Social cognition: learning about what matters in the social world

Social‐cognitive principles underlie people's learning about what matters in the social world. The benefits of these social‐cognitive principles reveal essential aspects of what it means to be human. But these social‐cognitive principles also have inherent costs , which highlight what it means to be ‘only human’. Social cognition is ‘social’ because what is learned concerns the social world, and where the learning takes place is in the social world. This paper reviews the benefits and costs of both sides of social cognition: (1) the cognition of social psychology principles of organization, explanation, knowledge activation and use; and (2) the social psychology of cognition principles of shared reality role enactment, social positions and identities and internal audiences. The fact that there are inherent costs of the same social‐cognitive principles for which there are essential benefits affords a new perspective on social‐cognitive costs that is different from either the classic ‘conflict’ perspective or the more current ‘limited capacity’ and ‘dual‐process’ perspectives. This ‘trade‐off’ perspective deepens both our understanding of the true nature of these principles and our appreciation of our common humanity. Copyright © 2000 John Wiley & Sons, Ltd.     

Detection of visual-tactile contingency in the first year after birth

It is well documented that in the first year after birth, infants are able to identify self-performed actions. This ability has been regarded as the basis of conscious self-perception. However, it is not yet known whether infants are also sensitive to aspects of the self when they cannot control the sensory feedback by means of self-performed actions. Therefore, we investigated the contribution of visual–tactile contingency to self-perception in infants. In Experiment 1, 7- and 10-month-olds were presented with two video displays of lifelike baby doll legs. The infant’s left leg was stroked contingently with only one of the video displays. The results showed that 7- and 10-month-olds looked significantly longer at the contingent display than at the non-contingent display. Experiment 2 was conducted to investigate the role of morphological characteristics in contingency detection. Ten-month-olds were presented with video displays of two neutral objects (i.e., oblong wooden blocks of approximately the same size as the doll legs) being stroked in the same way as in Experiment 1. No preference was found for either the contingent or the non-contingent display but our results confirm a significant decrease in looking time to the contingent display compared to Experiment 1. These results indicate that detection of visual–tactile contingency as one important aspect of self-perception is present very early in ontogeny. Furthermore, this ability appears to be limited to the perception of objects that strongly resemble the infant’s body, suggesting an early sensitivity to the morphology of one’s own body.     

Maternal adjustment during pregnancy and the infant''s first year

The study aimed at establishing the predictive validity of clinical observations and interview data collected during late pregnancy. 40 pregnant women from a Swedish non-risk population were interviewed about psychological and somatic well-being, significant relationships and delivery expectations. Pregnancy adjustment was also assessed by the maternal health clinic midwife. After the birth of the child, the mothers were interviewed in the delivery hospital and during home visits when the infants were 2 and 6 weeks, and 4, 8 and 12 months old. The results showed that pregnancy adjustment, as assessed by the mothers themselves, acted as a significant predictor of the early maternal adjustment and the adjustment towards the end of the infant's first year. The midwives' assessments significantly predicted maternal adjustment towards the end of the first year. Pregnancy data did not correlate with maternal delivery experiences.     

Continuity in mind-mindedness from pregnancy to the first year of life

Relations between parents' representations of the unborn child and postpartum infant-parent interaction were investigated in 25 couples and 3 solo mothers. In the last trimester of pregnancy, participants reported on involvement with the fetus and predicted what the unborn child would be like at age 6 months. Mothers (n=21) and fathers (n=17) were observed during separate interactions with their 6-month olds, which yielded measures of their tendency appropriately to interpret their infants' internal states (mind-mindedness). Parents' involvement with the fetus was unrelated to antenatal predictions and to postnatal mind-mindedness. Parents who had predicted more about the unborn child's characteristics were more likely to comment appropriately on their infants' internal states during infant-parent interaction. For fathers, overall antenatal predictions were also positively associated with misinterpretations of their infants' thoughts and feelings. Findings are discussed with reference to mind-mindedness being governed by caregiver-centered factors and differences between mothers and fathers in caregiving practices.     

Social cognition and its neural correlates in schizophrenia and autism

The study of social cognition in psychiatric disorders has become increasingly popular in recent years. This is due to the its proposed link to social functioning and the inability of general neurocognitive skills to explain the spectrum of impairments observed in patients. This article reviews research into two of the processes thought to underlie social cognition (emotion perception and theory of mind) in schizophrenia and autism. This is followed by a look at neuroimaging studies and their efforts to localize the neural correlates of emotion perception and theory of mind in the two disorders. We concluded that while a specific impairment in emotion perception and theory of mind skills cannot be generalized to all individuals with autism and schizophrenia, there are subpopulations that have lingering deficits of social cognition tasks. Neuroimaging work consistently points to the involvement of the fusiform gyrus and amygdala in emotion processing, while the medial prefrontal and frontal cortex are implicated in tasks invoking theory of mind. We propose that deficits of social cognition may benefit from cognitive remediation therapy and pharmacological cognitive enhancers.     

Infants’ scanning of dynamic faces during the first year

This research investigated infants’ scanning of a talking, socially engaging face. Three- to four-month-olds looked equally at the mouth and eyes whereas 9-month-olds attended more to the eyes than mouth. These findings shed light on information infants’ seek from dynamic face stimuli.     

Spatial updating and training effects in the first year of human infancy

The ability of infants to locate an invisible target after reorientation in their direction of facing was examined in a series of experiments. In a featureless environment, localization of the target site improved between 4 and 8 months. At 8 months it was shown to be dependent on the training procedure. Infants received either instrumental training in which they were trained to anticipate the occurrence of an event at the site, or association training in which one event immediately followed another regardless of their responses. After instrumental training, localization was dependent on visual cues whereas after association training it occurred whether or not visual cues were provided. Contrary to earlier findings, it was concluded that an updating strategy based on proprioceptive information is operative from the second half of the first year.     

Changes in students' motivation to learn during the first year of college

This study looks at changes in first-year college students' motivational orientation and whether these changes relate systematically to campus and classroom experiences. 130 college students (M age = 18 yr., 75% women) completed measures of learning orientation, grade orientation, and work avoidance from the LOGO II at the beginning and end of their first year. The year-end assessment also included questions regarding characteristics of students' classes and the amount of time they spent in campus activities. Students became more grade-oriented and work-avoidant and less learning-oriented over time. Changes in learning orientation and work avoidance were associated with classroom and campus experiences. Results are discussed in terms of the need for additional research on changes in college students' motivation and factors predicting this change.
