Salience network response to changes in emotional expressions of others is heightened during early adolescence: relevance for social functioning

Adolescence is a unique developmental period when the salience of social and emotional information becomes particularly pronounced. Although this increased sensitivity to social and emotional information has frequently been considered with respect to risk behaviors and psychopathology, evidence suggests that increased adolescent sensitivity to social and emotional cues may confer advantages. For example, greater sensitivity to shifts in the emotions of others is likely to promote flexible and adaptive social behavior. In this study, a sample of 54 children and adolescents (age 8–19 years) performed a delayed match‐to‐sample task for emotional faces while undergoing fMRI scanning. Recruitment of the anterior cingulate and anterior insula when the emotion of the probe face did not match the emotion held in memory followed a quadratic developmental pattern that peaked during early adolescence. These findings indicate meaningful developmental variation in the neural mechanisms underlying sensitivity to changes in the emotional expressions. Across all participants, greater activation of this network for changes in emotional expression was associated with less social anxiety and fewer social problems. These results suggest that the heightened salience of social and emotional information during adolescence may confer important advantages for social behavior, providing sensitivity to others’ emotions that facilitates flexible social responding.     

Learning about environmental geometry: a flaw in Miller and Shettleworth's (2007) operant model

Many studies have examined how humans and other animals reestablish a sense of direction following disorientation in enclosed environments. Results showing that geometric shape of an enclosure is typically encoded, sometimes to the exclusion of featural cues, have led to suggestions that geometry might be encoded in a dedicated geometric module. Recently, Miller and Shettleworth (2007) proposed that the reorientation task be viewed as an operant task and they presented an associative operant model that appears to account for many empirical findings from reorientation studies. In this paper we show that, although Miller and Shettleworth's insights into the operant nature of the reorientation task may be sound, their mathematical model has a serious flaw. We present simulations to illustrate the implications of the flaw. We also propose that the output of a simple neural network, the perceptron, can be used to conduct operant learning within the reorientation task and can solve the problem in Miller and Shettleworth's model.     

The relations between sex-typed play and preschoolers' social behavior

For decades toy choice has been a very popular measure of children's sex-role adoption. In the present study, the relations between choice of masculine, neutral, or feminine toys and other social behaviors (sex typed and non-sex typed) were examined. The social behaviors (socializing, requesting assistance, prosocial behaviors, aggressive/defensive behaviors) and toy choices of 33 preschool children were observed in their classrooms. Only two behaviors were found to be sex typed (socializing with peers and spontaneous prosocial behavior), and both of these behaviors were related to toy choice. Toy choice was also related to helping. Among boys, masculine toy choice was associated with requesting assistance from teachers. When toy choice was classified as masculine, androgynous, and feminine, only sociability toward peers was related to toy choice. The results are discussed in terms of their implications for the continued use of toy choice as a measure of sex-role adoption.The authors wish to express their gratitude to Rene Dodez for her assistance in data analysis and to the children and teachers at the Child Study Laboratory. We also appreciate the contributions of Drs. Laurie Chassin, Jerry Harris, Susan Somerville, Sharlene Wolchik, and Antonette Zeiss. This research was completed by the first author in partial fulfillment of the masters of arts degree at Arizona State University.     

Production and Identification Repetition Priming in AmnesticMild Cognitive Impairment

ABSTRACT

The experiment reported here examined implicit memory function, as measured through repetition priming, in amnestic mild cognitive impairment (MCI) to examine whether impairments exist in this aspect of memory function. Young adults, healthy older controls, Alzheimer's disease patients, and MCI participants were asked to perform two types of implicit memory tests (word stem completion and threshold identification repetition priming tasks), as well as a recognition test for studied items. As expected, young adults performed better than the other participants on the recognition test and the word stem completion task; there was equivalent priming across groups on the word identification task. While both the older control and MCI participants showed lower levels of priming on the word stem completion task relative to the young adults, the magnitude of priming was equivalent for these two groups, and reliably greater than that of the dementia participants. These results suggest that not all aspects of memory function are impaired in MCI relative to healthy aging.     

Cognitive reappraisal and secondary control coping: associations with working memory,positive and negative affect,and symptoms of anxiety/depression

Abstract

The current study examined the relations of measures of cognitive reappraisal and secondary control coping with working memory abilities, positive and negative affect, and symptoms of anxiety and depression in young adults (N=124). Results indicate significant relations between working memory abilities and reports of secondary control coping and between reports of secondary control coping and cognitive reappraisal. Associations were also found between measures of secondary control coping and cognitive reappraisal and positive and negative affect and symptoms of depression and anxiety. Further, the findings suggest that reports of cognitive reappraisal may be more strongly predictive of positive affect whereas secondary control coping may be more strongly predictive of negative affect and symptoms of depression and anxiety. Overall, the results suggest that current measures of secondary control coping and cognitive reappraisal capture related but distinct constructs and suggest that the assessment of working memory may be more strongly related to secondary control coping in predicting individual differences in distress.     

Assessment of dispositional embarrassability

Abstract

Embarrassability, the propensity for an individual to experience embarrassment, has been frequently acknowledged as an important personality characteristic. The present research sought to explore the dispositional features of embarrassability by the psychometric development of 25-item measure, the Susceptibility to Embarrassment Scale (SES). The SES was designed to describe the personality characteristics of easily embarrassed persons rather than reactions to potentially embarrassing situations. The results indicated that the SES was an internally consistent and temporally stable measure. Its items were uncontaminated by social desirability. Assessments of construct validity suggested that the scale was a valid measure of embarrassability, and specifically a better measure of dispositional components of embarrassability than the only alternative measure of the construct. The location of the SES within the Big Five structure of normal adult personality is presented as well as its relationship with measures of deviant personality.     

The accidental transgressor: morally-relevant theory of mind

To test young children’s false belief theory of mind in a morally relevant context, two experiments were conducted. In Experiment 1, children (N = 162) at 3.5, 5.5, and 7.5 years of age were administered three tasks: prototypic moral transgression task, false belief theory of mind task (ToM), and an “accidental transgressor” task, which measured a morally-relevant false belief theory of mind (MoToM). Children who did not pass false belief ToM were more likely to attribute negative intentions to an accidental transgressor than children who passed false belief ToM, and to use moral reasons when blaming the accidental transgressor. In Experiment 2, children (N = 46) who did not pass false belief ToM viewed it as more acceptable to punish the accidental transgressor than did participants who passed false belief ToM. Findings are discussed in light of research on the emergence of moral judgment and theory of mind.
