Flexibility is not always adaptive: Affective flexibility and inflexibility predict rumination use in everyday life

The present study examined whether cognitive flexibility in the processing of emotional material (i.e., affective flexibility) predicts the use of rumination in response to negative events in daily life. One hundred fifty-seven undergraduate participants completed daily diaries for six consecutive days. Affective flexibility was measured with a novel task-switching paradigm using emotional pictures. Results show that affective inflexibility when switching away from processing the emotional meaning of negative material was associated with increased use of rumination in daily life. In contrast, affective inflexibility when switching away from processing the emotional meaning of positive material was related to decreased use of rumination. Importantly, affective flexibility predicted use of rumination beyond non-affective measures of executive functioning. This is the first study to show that inflexibility is not uniformly associated with increased rumination but that inflexibility in the processing of positive material can predict lower levels of rumination.     

Coloring-book-type experiences and children's divergent pictorial production

Sixty-four children in kindergarten and first grade were asked to color one of three pictures which varied in complexity. Following the coloring exercise the children were administered the CIRCUS: Make a Tree, a measure of divergent pictorial production which yields three scores (Appropriateness, Unusualness, Difference). A one-way ANOVA revealed a main effect of the coloring exercise in Unusualness and Difference. The findings suggest that giving children models to color can increase the novelty displayed in their subsequent productions, and that giving children complex models to color can increase the variety displayed in the pictures that they make. The findings are consistent with Gardner's (1980) suggestion that adult models can contribute to the substance of the child's pictoral productions by providing new ideas and information about how to achieve desired effects, and that they do not necessarily induce the slavish copying feared by many early childhood- and art-educators.

Emergence of attributional style and its relation to depressive symptoms

The development of depressive attributional style (AS) and its role as a cognitive diathesis for depression were examined in children and adolescents (Grades 2-9). In a 4-wave longitudinal study of 3 overlapping age cohorts, AS, negative life events, and depressive symptoms were evaluated every 12 months. Consistency of children's attributions across situations was moderately high at all ages. The cross-sectional structure of AS changed with age, as stability became a more salient aspect of AS than internality and globality. The structure of AS also changed, becoming more traitlike as children grew older. In longitudinal analyses, evidence of a Cognitive Diathesis x Stress interaction did not emerge until Grades 8 and 9, suggesting that AS may not serve as a diathesis for depression at younger ages. Results suggest that attributional models of depression may require modification before they are applied across developmental levels.     

The mediation of mothers' self-fulfilling effects on their children's alcohol use: self-verification, informational conformity, and modeling processes

This research examined whether self-fulfilling prophecy effects are mediated by self-verification, informational conformity, and modeling processes. The authors examined these mediational processes across multiple time frames with longitudinal data obtained from two samples of mother-child dyads (N-sub-1 = 486; N-sub-2 = 287), with children's alcohol use as the outcome variable. The results provided consistent support for the mediational process of self-verification. In both samples and across several years of adolescence, there was a significant indirect effect of mothers' beliefs on children's alcohol use through children's self-assessed likelihood of drinking alcohol in the future. Comparatively less support was found for informational conformity and modeling processes as mediators of mothers' self-fulfilling effects. The potential for self-fulfilling prophecies to produce long-lasting changes in targets' behavior via self-verification processes are discussed.     

The Relationship of Physiological Arousal with Demand and Withdraw Behavior: Examining the Accuracy of the Escape-Conditioning Hypothesis

The escape-conditioning model suggests that husbands experience greater physiological arousal during marital conflict than their wives. This greater arousal is hypothesized to lead to withdrawal from conflict in order to lessen the arousal. The present results, based on a U.S. sample of 64 heterosexual couples, found no support for this model. During problem-solving discussions, husbands did not exhibit greater skin conductance and did not report greater arousal than their wives. Furthermore, skin conductance was negatively linked to withdraw behavior. These results, while not consistent with the escape-conditioning model, are in line with recent studies that have explicitly examined gender differences in other types of physiological arousal during marital conflict.     

The effects of prenatal stress on motivation in the rat pup

Exposure to prenatal stress (PNS) has been shown to induce a set of psychological and behavioral changes in developing offspring. We used the rodent model to investigate whether PNS produces changes in the ability of the pup to express social motivation. We used a set of behavioral tasks including monitoring ultrasonic vocalizations after isolation, a conditioned place preference, and a novel and familiar odor approach test. Pregnant Long-Evans rats were exposed to an unpredictable, variable stressor twice daily during the third week of gestation. Isolation vocalizations were assessed on postnatal day (PND) 10. Pup affinity for the dam was evaluated on PND 15. Typically, pups display a selective preference for an odor-paired environment only after the odor has been associated with the dam. This previous association produces a positive conditioned stimulus (CS). Normally, pups exposed to a neutral CS (odor paired with cotton balls) do not form this place preference. Results indicate that PNS exposed pups had significantly increased distress vocalizations and an equal preference for the positive and neutral conditioned stimuli. This type of alteration in forming early preferences could be detrimental because of decreases in the specificity of social learning and an impaired responsiveness in social relationships.     

Race-based perceptual asymmetries underlying face processing in infancy

Adults process other-race faces differently than own-race faces. For instance, a single other-race face in an array of own-race faces attracts Caucasians’ attention, but a single own-race face among other-race faces does not. This perceptual asymmetry has been explained by the presence of an other-race feature in other-race faces and its absence in own-race faces; this difference is thought to underlie race-based differences in face processing. We examined the developmental origins of this mechanism in two groups of Caucasian 9-month-olds. Infants in the experimental group exhibited a preference for a pattern containing a single Asian face among seven Caucasian faces over a pattern containing a single Caucasian face among seven Asian faces. This preference was not driven by the majority of elements in the images, because a control group of infants failed to exhibit a preference between homogeneous patterns containing eight Caucasian versus eight Asian faces. The results demonstrate that an other-race face among own-race faces attracts infants’ attention but not vice versa. This perceptual asymmetry suggests that the other-race feature is available to Caucasians by 9 months of age, thereby indicating that mechanisms of specialization in face processing originate early in life.
