Inhibition and exuberance in preschool classrooms: associations with peer social experiences and changes in cortisol across the preschool year

Associations between behavioral inhibition and activity of the hypothalamic-pituitary-adrenocortical (HPA) system, a stress-sensitive neuroendocrine system indexed by salivary cortisol, have varied widely across studies. In the current study, we examined the role of peer social experiences in moderating patterns of association between inhibition/risk-aversion and cortisol reactivity. As expected based on previous research, preschool children (N = 165, 78 boys, 87 girls, 3.0-5.0 years) had significantly different social experiences in their preschool classrooms depending on temperament. Highly inhibited/risk-averse children were less socially integrated, less dominant, and less involved in aggressive encounters than both average and highly exuberant/risk-seeking children, but they were no more likely to be peer rejected. Highly exuberant children were more dominant, exhibited anger more often, and had friendships characterized by higher conflict. Cortisol levels fell from fall to spring for average and highly exuberant children but not for highly inhibited children. Unexpectedly, for highly inhibited children, having friends and being more dominant and popular than other highly inhibited children was associated with increasing cortisol levels over the school year. In contrast, highly exuberant children who were less socially integrated than other highly exuberant children maintained higher cortisol levels. Results indicate that the types of social experiences that affect stress-responsive biological systems may differ markedly for highly inhibited and highly exuberant children.     

Recollection is impaired by the modification of interpretation bias

The interpretation paradigm of cognitive-bias modification (CBM-I) was modified with instructions used in process-dissociation procedures for the purpose of investigating processes contributing to performance on the transfer task. In Experiment 1, nonanxious students were trained to interpret ambiguous situations in either a negative or benign way (or they read nonambiguous scenarios). They were then asked to respond to new ambiguous situations, in the same way as contextually similar analogues during training, or to respond differently. Benign training proactively impaired memory for negative outcomes. This effect was replicated by anxious students in Experiment 2 and discussed with respect to the assumptions underlying process-dissociation procedures and directions for future research.     

Cultural intersections: a qualitative inquiry into the experience of Asian Indian-White interracial couples

The purpose of this study was to examine the "lived experience" of Asian Indian (AI)-White couples in interracial marriages. Ten highly educated AI-White professional couples were individually interviewed about their subjective experience of being in an interracial marriage, the challenges and strengths of this marriage, and the potential role of culture in their marriages. Data were analyzed using the Consensual Qualitative Research methodology. Results indicated that the couples' marital experiences were influenced by a complex intersection of ecosystemic factors with significant psychological impacts. These findings highlight shortcomings in drawing simplistic conclusions regarding the success or failure of an interracial marriage and have important implications for theory, research, and clinical practice.     

Piecing together numerical language: children's use of default units in early counting and quantification

When asked to ‘find three forks’, adult speakers of English use the noun ‘fork’ to identify units for counting. However, when number words (e.g. three) and quantifiers (e.g. more, every) are used with unfamiliar words (‘Give me three blickets’) noun‐specific conceptual criteria are unavailable for picking out units. This poses a problem for young children learning language, who begin to use quantifiers and number words by age 2, despite knowing a relatively small number of nouns. Without knowing how individual nouns pick out units of quantification – e.g. what counts as a blicket– how could children decide whether there are three blickets or four? Three experiments suggest that children might solve this problem by assigning ‘default units’ of quantification to number words, quantifiers, and number morphology. When shown objects that are broken into arbitrary pieces, 4‐year‐olds in Experiment 1 treated pieces as units when counting, interpreting quantifiers, and when using singular–plural morphology. Experiment 2 found that although children treat object‐hood as sufficient for quantification, it is not necessary. Also sufficient for individuation are the criteria provided by known nouns. When two nameable things were glued together (e.g. two cups), children counted the glued things as two. However, when two arbitrary pieces of an object were put together (e.g. two parts of a ball), children counted them as one, even if they had previously counted the pieces as two. Experiment 3 found that when the pieces of broken things were nameable (e.g. wheels of a bicycle), 4‐year‐olds did not include them in counts of whole objects (e.g. bicycles). We discuss the role of default units in early language acquisition, their origin in acquisition, and how children eventually acquire an adult semantics identifying units of quantification.     

Intimacy in young adults' narratives of romance and friendship predicts Eriksonian generativity: a mixed method analysis

A quantitative and qualitative study tested Erikson's ego developmental hypotheses regarding the positive relationship between generativity and intimacy. At age 26, participants (N = 100) told 2 stories about "relationship-defining moments," one about a romantic partner, and another about a same-sex friend. Levels of relationship intimacy were coded from these narratives. "True love" and "true friendship" themes arose as the most prototypical, highly intimate stories. Romantic intimacy and friendship intimacy as coded from narratives each contributed uniquely to the prediction of generative concern; as intimacy in each domain increased, so did generative concern. This relationship remained statistically significant, even when controlling for gender, current romantic relationship status, subjective well-being, optimism, and depressive symptoms. Results suggest that our "relationship-defining moment" narrative task is a useful tool for examining development in emerging adulthood and that intimacy may be an important precursor to generative concern in early adulthood, consistent with Erikson's model.     

Co-Rumination Exacerbates Stress Generation among Adolescents with Depressive Symptoms

Through stress generation, individuals’ own thoughts and behaviors can actually lead to increases in their experience of stress. Unfortunately, stress generation is especially common among individuals who are already suffering from elevated depressive symptoms. However, despite the acknowledgement that some individuals with depressive symptoms generate greater stress than others, few studies have identified specific factors that could exacerbate stress generation among individuals with depressive symptoms. The present study examines co-rumination as a factor that might exacerbate stress generation among adolescents with depressive symptoms using a short-term longitudinal design. Considering these processes among adolescents was critical given that many youth experience increases in depressive symptoms at this developmental stage and that co-rumination also becomes more common at adolescence. Participants were 628 adolescents (326 girls; 302 boys) who reported on their depressive symptoms, experiences of stress, and co-rumination with a best friend. Interpersonal stressors (peer and family stress) and non-interpersonal stressors (school and sports stress) were assessed. Consistent with past research, adolescents with depressive symptoms experienced greater interpersonal and non-interpersonal stress over time. Importantly, co-rumination interacted with both depressive symptoms and gender in predicting increases in peer stress. Depressive symptoms predicted the generation of peer stress only for girls who reported high levels of co-rumination with friends. Implications for protecting youth with depressive symptoms against stress generation are discussed.     

Relational Aggression in Mothers and Children: Links with Psychological Control and Child Adjustment

This study assesses associations between mothers’ use of relational aggression with their peers and psychological control with their children, and child adjustment in a sample of fifty U.S. mothers of elementary and middle school children. Mothers completed surveys assessing their relational aggression and psychological control. Teachers completed surveys assessing children’s externalizing behavior, internalizing symptoms, and relational aggression. Results suggest that mothers who are relationally aggressive with their peers are more likely to be psychologically controlling with their children. Results also showed that relational aggression predicted adjustment problems in youth. Relational aggression was associated with externalizing problems among boys and girls, and with internalizing problems among boys. Few gender differences in mean levels of maternal or child behaviors emerged.     

D-cycloserine facilitates context-specific fear extinction learning

D-cycloserine (DCS) may facilitate fear extinction learning, but the behavioral consequences and mechanisms behind this effect are not well understood at present. In this paper, we re-analyze data from previously reported null result experiments and find that rats showing above-median extinction learning during DCS treatment benefited from the drug, whereas rats showing below-median (and in this case little) extinction learning did not. Two additional experiments found that DCS facilitated extinction learning when specifically combined with a moderate, but not a small, number of extinction trials. DCS thus facilitates extinction learning only if the behavioral procedure first engages the extinction learning process. The benefits of the drug, however, were specific to the context in which extinction was learned--i.e., DCS did not prevent or influence the renewal of fear observed when the extinguished cue was tested in the original conditioning context.     

Exposure to Scientific Explanations for Gender Differences Influences Individuals’ Personal Theories of Gender and Their Evaluations of a Discriminatory Situation

Sex Roles - Gender lay theory is a framework of information interpretation related to gender categorisation and can be divided into two general forms: gender essentialism versus gender as socially...     

Gender Role Beliefs and Attitudes toward Lesbians and Gay Men in Chile and the U.S.

We compared the relationship between gender role beliefs and antigay prejudice in Chile and the United States. Participants were Chilean and American university students. In Study 1, Chileans were more prejudiced than Americans, and men were more prejudiced than women. In Study 2, gender role beliefs mediated cultural and sex differences in prejudice. Chileans held more traditional gender role beliefs and were more antigay than Americans. Men were more prejudiced than women, particularly in their attitudes toward gay men. Further, sex differences in attitudes toward lesbians and gay men were completely mediated by gender role beliefs. Nationality differences in attitudes toward lesbians were completely mediated, and nationality differences in attitudes toward gay men were partially mediated, by gender role beliefs.
