Little Girls in Women's Bodies: Social Interaction and the Strategizing of Early Breast Development

The purpose of this study was to analyze early breast developers' narratives of their experience of early development to understand the patterns of social interaction and resulting emotion that generated the meaning of their breasts and their bodies. Thirteen women were interviewed, and three of their stories were selected to tell in detail to demonstrate the various strategies of interaction that these women developed as girls in response to the social context of their early breast development. These results suggest that whether early breast developers rely on proactive or defensive strategies for managing their breasts has implications for their ways of thinking and feeling about their sexuality and their bodies. This research also helps to illuminate the significance of social interaction in generating the meaning of breasts and of femininity more generally.     

THE EFFECTS OF CHILDHOOD EXPOSURE TO MARITAL VIOLENCE ON ADOLESCENT GENDER-ROLE BELIEFS AND DATING VIOLENCE

Children exposed to marital violence in childhood are at risk for engaging in dating violence as adolescents or young adults. Using a longitudinal prospective design, mother–child pairs from violent and nonviolent homes ( N = 208) were interviewed about exposure to marital violence twice over a 7–9 year time span. Responses to questions about adolescent gender-typed beliefs, the acceptance of dating violence, and experiences with dating violence were collected during follow-up interviews. Results indicated that adolescents exposed to marital violence during childhood were more likely to justify the use of violence in dating relationships. Possessing traditional attitudes of male–female relationships and justifying relationship violence were associated with higher levels of dating violence perpetration regardless of marital violence exposure. How adolescents thought about dating relationships was more important than whether they witnessed marital violence in childhood. Results have implications for social-cognitive and norm-based interventions.     

The Relationship Quality Interview: evidence of reliability, convergent and divergent validity, and incremental utility

Relationship satisfaction and adjustment have been the target outcome variables for almost all couple research and therapies. In contrast, far less attention has been paid to the assessment of relationship quality. The present study introduces the Relationship Quality Interview (RQI), a semistructured, behaviorally anchored individual interview. The RQI was designed to provide a more objective assessment of relationship quality as a dynamic, dyadic construct across 5 dimensions: (a) quality of emotional intimacy in the relationship, (b) quality of the couple's sexual relationship, (c) quality of support transactions in the relationship, (d) quality of the couple's ability to share power in the relationship, and (e) quality of conflict/problem-solving interactions in the relationship. Psychometric properties of RQI ratings were examined through scores obtained from self-report questionnaires and behavioral observation data collected cross-sectionally from a sample of 91 dating participants and longitudinally from a sample of 101 married couples. RQI ratings demonstrated strong reliability (internal consistency, interrater agreement, interpartner agreement, and correlations among scales), convergent validity (correlations between RQI scale ratings and questionnaire scores assessing similar domains of relationship quality), and divergent validity (correlations between RQI scale ratings and (a) behavioral observation codes assessing related constructs, (b) global relationship satisfaction scores, and (c) scores on individual difference measures of related constructs). Clinical implications of the RQI for improving couple assessment and interventions are discussed.     

Epigenetics in the mature mammalian brain: effects on behavior and synaptic transmission

The role of epigenetic mechanisms in control of gene expression during mammalian development is well established. Associations between specific DNA or histone modifications and numerous neurodevelopmental and neurodegenerative disorders implies significant consequences of epigenetic dysregulation in both the developing and mature brain, the latter of which is the general focus of this review. Accumulating evidence suggests that epigenetic changes are involved in normal cognitive processes in addition to neurological and psychiatric disorders. Recent investigations into the regulation of epigenetic modifications in the adult brain have revealed novel and surprisingly dynamic mechanisms for controlling learning and memory-related behaviors as well as long-term synaptic plasticity. DNA methylation and histone acetylation have also been implicated in the modulation of basal synaptic transmission and the balance between excitation and inhibition in various brain regions. Studies have begun to uncover some of the alterations in gene expression that appear to mediate many of these effects, but an understanding of the precise mechanisms involved is still lacking. Nevertheless, the fundamental importance of epigenetic processes in influencing neuronal activity is becoming increasingly evident.     

Defense attorneys' concerns about the competence of adolescent defendants

Research indicates that a sizable proportion of adolescent defendants have difficulty understanding and participating in legal proceedings against them, and may be incompetent to stand trial. To examine attorneys' experience in defending adolescents with competence‐related difficulties, 214 juvenile attorneys were surveyed. Findings indicated that attorneys have doubts about the competence of approximately 10% of adolescent defendants, and that they find these cases particularly challenging to defend. Most attorneys appear to recognize that developmental factors may contribute to adolescents' competence‐related difficulties, and believe that the law should accept developmental immaturity as a basis for incompetence findings. In approximately half of the cases in which attorneys had doubts about competence, attorneys did not request a competence evaluation but instead made other efforts to address competence issues, such as by teaching adolescents about legal proceedings and further involving their parents. The implications of these findings are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

Response Conflict and Affective Responses in the Control and Expression of Race Bias

Models of racial attitudes traditionally have assumed that individual differences in the strength of underlying, 'implicit' associations between racial categories and stereotypical traits are the primary determinant of the expression of race bias. Thus, individual differences in performance on laboratory tasks designed to assess implicit race bias tend to be interpreted in terms of association strength. Here, we argue that such associations tell only part of the story, and probably the least interesting part. We posit that response conflict and its regulation are critical to understanding the need for control, and that affect-related processes help to determine the extent to which control resources will be implemented to overcome biased associations. We present data from a number of recent behavioral and psychophysiological studies in support of this idea, as well as conceptual accounts that point toward a model of race bias regulation that depends upon processes identified as important for regulation of thought, affect and action more generally.     

Stepping up the pressure: arousal can be associated with a reduction in male aggression

The attentional myopia model of behavioral control [Mann and Ward, 2007] was tested in an experiment investigating the relationship between physiological arousal and aggression. Drawing on previous work linking arousal and narrowed attentional focus, the model predicts that arousal will lead to behavior that is relatively disinhibited in situations in which promoting pressures to aggress are highly salient. In situations in which inhibitory pressures are more salient, the model predicts behavior that is relatively restrained. In the experiment, 81 male undergraduates delivered noise-blasts against a provoking confederate while experiencing either high or low levels of physiological arousal and, at the same time, being exposed to cues that served either to promote or inhibit aggression. In addition to supporting the predictions of the model, this experiment provided some of the first evidence for enhanced control of aggression under conditions of heightened physiological arousal. Implications for interventions designed to reduce aggression are discussed.     

Children’s Affect Expression and Frontal EEG Asymmetry: Transactional Associations with Mothers’ Depressive Symptoms

Although parents and children are thought to influence one another's affect and behavior, few studies have examined the direction of effects from children to parents, particularly with respect to parental psychopathology. We tested the hypothesis that children's affective characteristics are associated with the course of mothers' depressive symptoms. Children's affect expression was observed during a series of mother-child interaction tasks, and children's resting frontal electroencephalogram (EEG) asymmetry was assessed in a psychophysiology laboratory. Mothers' depressive symptoms were assessed at two time points, approximately one year apart, at the mother-child interaction visits. Depressive symptoms increased over time for mothers with a history of childhood-onset depression whose children exhibited right frontal EEG asymmetry. Depressive symptoms were associated with high child negative affect at both time points for mothers whose children exhibited right frontal EEG asymmetry. Cross-lagged models with a subset of participants provided some evidence of both parent-to-child and child-to-parent directions of effects. Findings suggest that akin to other interpersonal stressors, children's affective characteristics may contribute to maternal depressive symptoms.     

Visual identity and uncertainty in repetition blindness

Repetition blindness (RB) was investigated in 6 experiments. In the first 3 experiments participants detected vowel targets in 11-letter sequences. When all letters were uppercase, detection was poorer for same (e.g., AA) than for different (e.g., AO) targets. However, when one target was uppercase and the other lowercase, RB was found only for targets visually identical except for size (e.g., Oo), not for visually different pairs (e.g., Aa). Experiment 4 found RB for visually identical versus different consonant-vowel-consonant words. Experiments 5 and 6 replicated Kanwisher's (1987) experiment in which RB was insensitive to word case but revealed these effects to be artifacts of poor recognition of 5-letter words coupled with a biased guessing strategy. Overall, these experiments found RB only at a low level of visual information processing.
