Gender Segregation in Childhood: A Test of the Interaction Style Theory

The authors investigated the play/interaction-style theory of gender segregation with a sample of 39 children aged 2 to 5 years (primarily Caucasian). According to this theory, children prefer playmates with styles of play or interaction that are similar to their own. Because such styles are sex differentiated, same-sex playmate preference (i.e., gender segregation) results. The authors observed children during free play to determine preferred playmates and gender segregation level, and they used teacher ratings to derive play/interaction-style scores. The authors used a multiple regression approach to path analysis to analyze effects of sex of participant, participants' play/interaction-style scores, playmates' play/interaction-style scores, and degree of gender segregation to determine their effects on one another. The authors observed significant levels of gender segregation, with highly aggressive or active children displaying less segregation than their peers did. However, gender segregation was not associated with a preference for playmates with similar play or interaction styles.     

Associative change in the representations acquired during conditional discriminations: further analysis of the nature of conditional learning

Three experiments with rats investigated how the associative strengths of the representations that underlie conditional learning change when they are conditioned in compound. The results of each experiment suggest that the representation whose associative strength is most discrepant from the asymptote supported by the outcome of the trial undergoes the greatest change in associative strength. These results parallel those from simple Pavlovian conditioning (e.g., R. A. Rescorla, 2000). are inconsistent with unique-cue and configural accounts of conditional learning, and support a connectionist analysis of learning in which a "winner-takes-all" rule applies to the hidden units that can be activated and acquire associative strength at a given point in time.     

Personality traits prospectively predict verbal fluency in a lifespan sample

In a community-dwelling sample (N = 4,790; age range 14-94), we examined whether personality traits prospectively predicted performance on a verbal fluency task. Open, extraverted, and emotionally stable participants had better verbal fluency. At the facet level, dispositionally happy and self-disciplined participants retrieved more words; those prone to anxiety and depression and those who were deliberative retrieved fewer words. Education moderated the association between conscientiousness and fluency such that participants with lower education performed better on the fluency task if they were also conscientious. Age was not a moderator at the domain level, indicating that the personality-fluency associations were consistent across the life span. A disposition toward emotional vulnerability and being less open, less happy, and undisciplined may be detrimental to cognitive performance.     

Examinations of identity invariance in facial expression adaptation

Faces provide a wealth of information essential to social interaction, including both static features, such as identity, and dynamic features, such as emotional state. Classic models of face perception propose separate neural-processing routes for identity and facial expression (Bruce & Young, 1986), but more recent models suggest that these routes are not independent of each other (Calder & Young, 2005). Using a perceptual adaptation paradigm in the present study, we attempted to further examine the nature of the relation between the neural representations of identity and emotional expression. In Experiment 1, adaptation to the basic emotions of anger, surprise, disgust, and fear resulted in significantly biased perception away from the adapting expression. A significantly decreased aftereffect was observed when the adapting and the test faces differed in identity. With a statistical model that separated surface texture and reflectance from underlying expression geometry, Experiment 2 showed a similar decrease in adaptation when the face stimuli had identical underlying prototypical geometry but differed in the static surface features supporting identity. These results provide evidence that expression adaptation depends on perceptual features important for identity processing and thus suggest at least partly overlapping neural processing of identity and facial expression.     

Improving the Social-Behavioral Adjustment of Adolescents: The Effectiveness of a Social Skills Group Intervention

We evaluated the efficacy of a social skills training intervention designed to improve adolescents’ social, emotional and behavioral adjustment, Social Skills Group Intervention-Adolescent (S.S.GRIN-A). Seventy-four adolescents (ages 13–16 years) and their parents were randomly assigned to either the treatment group (N = 40) or a wait-list control group (N = 34). Adolescents in the treatment and control groups were compared on global self-concept, social self-efficacy, internalizing problems, and externalizing problems pre- and post-intervention. Youth in the treatment group demonstrated enhanced global self-concept, increased social self-efficacy, and decreased internalizing problems as compared to youth in the control group. No differences in externalizing behavior were found. We discuss the effectiveness of S.S.GRIN-A as a general program designed for addressing a range of adjustment issues and social skill deficits in adolescents.     

A Study of the Benefit of Social and Religious Support on Church Members During Times of Crisis

A majority of Americans participate in religious services and identify themselves as members of a faith community. Understanding the role that religion plays in people's lives is essential to developing a comprehensive model of social support during times of crisis. The purpose of the current study was to identify the resources of social support that are helpful for church members during times of crisis. Although research on the impact of social support has identified several types of support—and the function of such support—to people undergoing difficult times, researchers have not looked at the impact of religious beliefs and participation in religious communities on social support to any significant extent. The current study collected questionnaire data from 23 members of one congregation who experienced a personal crisis. Analysis of the data shows that religious beliefs and the support provided by the religious community were seen as extremely helpful in times of crisis. Implications for incorporating people's religious beliefs and participation in religious communities into future investigations of social support are discussed.     

Depression and attachment in families: a child-focused perspective

Given the social nature and developmental implications of attachment and depression, in this review we will examine the role of attachment and the effects of a depressed family member at each stage of a child's development. We discuss treatment strategies for families in which either a parent or a child is depressed. We propose a model that is based on the developmental phase of the children in the family, and that aims to strengthen attachment bonds among family members and alleviate depressive symptoms.     

Why misinformation is more likely to be recognised over time: A source monitoring account

Although memory for actual events tends to be forgotten over time, memory for misinformation tends to be retrieved at a stable rate over long delays or at a rate greater than that found immediately after encoding. To examine whether source monitoring errors contribute to this phenomenon, two experiments investigated subjects' memory for the source of misinformation at different retention intervals. Subjects viewed a slide presentation, read a narrative containing misinformation, and, either 10 minutes or 1 week later, completed a recognition test about details seen in the slides and about the source of these details. After the longer retention interval in both experiments, participants were more likely to agree that they had seen misleading information and were also more likely to incorrectly associate the misinformation with the slide event. Theoretical implications of these findings are considered.     

Hippocampal damage and exploratory preferences in rats: memory for objects, places, and contexts

Rats have a natural tendency to spend more time exploring novel objects than familiar objects, and this preference can be used as an index of object recognition. Rats also show an exploratory preference for objects in locations where they have not previously encountered objects (an index of place memory) and for familiar objects in contexts different from those in which the objects were originally encountered (an index of context memory). In this experiment, rats with cytotoxic lesions of the hippocampal formation were tested on all three versions of the novelty-preference paradigm, with a 5-min retention interval between the familiarization and test phases. Rats with sham lesions displayed a novelty preference on all three trial types, whereas the rats with hippocampal lesions displayed a novelty preference on Object trials but did not discriminate between the objects on Place trials or Context trials. The findings indicate that hippocampal damage impairs memory for contextual or spatial aspects of an experience, whereas memory for objects that were part of the same experience are left relatively intact.     

The role of inferences about referential intent in word learning: evidence from autism

Young children are readily able to use known labels to constrain hypotheses about the meanings of new words under conditions of referential ambiguity. At issue is the kind of information children use to constrain such hypotheses. According to one theory, children take into account the speaker's intention when solving a referential puzzle. In the present studies, children with autism were impaired in monitoring referential intent, but were equally successful as normally developing 24-month-old toddlers at mapping novel words to unnamed items under conditions of referential ambiguity. Therefore, constraints that lead the child to map a novel label to a previously unnamed object under these circumstances are not solely based on assessments of speakers' intentions.
