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.     

Effects of interviewer behavior on accuracy of children's responses

Previous research has shown that certain interviewer behaviors can evoke inaccurate answers by children. In the current study, we examined the effects of approving and disapproving statements on the accuracy of 3 children's answers to questions in an interview (Experiment 1). We then evaluated 3 questioning techniques that may be used by interviewers during a forensic interview in which a child provides eyewitness testimony (Experiment 2). All participants responded with more inaccurate answers when approving statements followed inaccurate information and disapproving statements followed accurate information in Experiment 1. During Experiment 2, 1 participant responded most inaccurately when she was requestioned after providing an initial answer, whereas the remaining 2 participants responded most inaccurately when the interviewer provided cowitness information and suggestive questions.     

The Contribution of Deficits in Emotional Clarity to Stress Responses and Depression

This research investigated the contribution of deficits in emotional clarity to children's socioemotional adjustment. Specifically, this study examined the proposal that deficits in emotional clarity are associated with maladaptive interpersonal stress responses, and that maladaptive interpersonal stress responses act as a mechanism linking deficits in emotional clarity to childhood depressive symptoms. Participants included 345 3(rd) graders (M age = 8.89, SD = .34) assessed at two waves, approximately one year apart; youth completed self-report measures of emotional clarity, responses to interpersonal stress, and depressive symptoms. Results supported the hypothesized process model linking deficits in emotional clarity, maladaptive interpersonal stress responses, and depressive symptoms, adjusting for prior depressive symptoms. Findings have implications for theories of emotional competence and for depression-intervention efforts aimed at fostering emotional understanding and adaptive interpersonal stress responses.     

Spatial vision meets spatial cognition: examining the effect of visual blur on human visually guided route learning

Visual navigation is a task that involves processing two-dimensional light patterns on the retinas to obtain knowledge of how to move through a three-dimensional environment. Therefore, modifying the basic characteristics of the two-dimensional information provided to navigators should have important and informative effects on how they navigate. Despite this, few basic research studies have examined the effects of systematically modifying the available levels of spatial visual detail on navigation performance. In this study, we tested the effects of a range of visual blur levels--approximately equivalent to various degrees of low-pass spatial frequency filtering--on participants' visually guided route-learning performance using desktop virtual renderings of the Hebb-Williams mazes. Our findings show that the function of blur and time to finish the mazes follows a sigmoidal pattern, with the inflection point around +2 D of experienced defocus. This suggests that visually guided route learning is fairly robust to blur, with the threshold level being just above the limit for legal blindness. These findings have implications for models of route learning, as well as for practical situations in which humans must navigate under conditions of blur.     

A Pilot Study of Psychotherapist Trainees' Alpha-Amylase and Cortisol Levels During Treatment of Recently Suicidal Clients With Borderline Traits

Psychotherapists often experience stress while providing psychotherapy, in particular when working with difficult presentations such as suicidality. As part of a larger study on the treatment of recently suicidal college students with borderline traits, 6 therapists in training collected their own salivary samples for alpha-amylase (AA) and cortisol (C) analyses immediately before and after sessions with 2 selected clients. On average, samples were collected for the same therapist-patient dyad throughout the year-long study to ensure that data reflected therapist responses across stages of treatment. Therapists also completed a working alliance questionnaire and rated perceived session difficulty immediately after each selected session. Contrary to expectations, therapists demonstrated elevated levels of stress as measured by AA and C at presession relative to postsession levels. Greater session difficulty was related to more pronounced declines in AA, whereas a stronger working alliance was linked to more pronounced reductions in C. Results suggest that physiological stress responses while working with recently suicidal clients with borderline traits occur primarily in terms of session anticipatory anxiety, whereas AA and C changes may be affected differently by factors such as session difficulty and working alliance. This is a pilot study, limited by its sample size, but the design, findings, and inclusion of physiological measures present an initial step in an essential line of research.     

Using Technology to Enhance Adult Learning in the Counselor Education Classroom

The authors present a study that used a conceptual framework of adult learning and differentiated learning styles with graduate students in a counselor education classroom. Students in a hybrid course had higher midterm, group proposal, and posttest scores than did students in a face‐to‐face course taught by the same professor.     

Developmental changes in the responses of preterm infants to a painful stressor

The purpose of this investigation was to examine longitudinally gestational age and developmental differences in preterm infants' self-regulatory abilities in response to a painful stressor, as well as associations between behavioral and cardiovascular responses. Participants included 49 healthy premature infants. Behavioral and cardiovascular responses to a heel stick blood draw were compared between infants of 28-31 and 32-34 weeks' gestation age at birth. Both gestational age groups displayed behavioral and cardiovascular indications of stress in response to the blood draw. However, both shortly after birth and several weeks later, infants born at younger gestational ages (28-31 weeks) were more physiologically reactive. Evidence that the behavioral stress responses of 28-31 weeks' gestation age group preterm infants do not reflect their physiological responses suggests that evaluation of preterm infants' experiences and risk require assessments of both physiology and behavior. The greater stress vulnerability of the 28-31 weeks' gestation group relative to the 32-34 weeks' gestation group and the implications of this for subsequent development are discussed.     

The human Müller-Lyer illusion in goalkeeping

We examined whether a goalkeeper can influence a penalty-taker's actions by assuming postures that mimic Müller-Lyer configurations. The results of two studies indicate that (i) goalkeeper posture affects the perception of the goalkeeper's height in a manner consistent with the Müller-Lyer illusion; (ii) this influences penalty-taking accuracy; and (iii) a posture which resembles a wing-out Müller-Lyer configuration results in wider and lower throws.     

Identity in Action: Predictors of Feminist Self-Identification and Collective Action

The present study sought to explore how women's life experiences influenced their beliefs, and how those beliefs in turn influenced feminist self-identification. Additionally, we sought to determine whether feminist self-identification led to increased collective action on behalf of women. Female participants (N?=?282) from two US college campuses and online listservs completed an online survey assessing feminist self-identification, collective action, and life experiences. Conservative, liberal, and radical beliefs were assessed as were evaluations of feminists. A structural equation model was used to explore these relationships; life experiences were found to influence women's beliefs, which in turn influenced feminist self-identification, which influenced collective action. We found that life experiences may serve as a catalyst for both feminist self-identification and collective action.     

Putting Values into Practice: Public Policy and the Future of Mental Health Consumer-run Organizations

The purpose of the paper is to reflect on value dilemmas in mental health consumer-run organizations and to discuss implications for research, policy, and practice. We review the roots of consumer-run organizations in the self-help movement and the psychiatric survivor liberation movement, focusing on the distinctive values espoused by consumer-run organizations. We also discuss evidence-based and value-based approaches to mental health policy formulation and mental health reform, noting the particular importance of value-based approaches and the role that consumer-run organizations can play in mental health reform. Based on our experiences conducting a participatory action research study of four mental health consumer-run organizations, we identify and examine several value dilemmas, discuss the lessons that we learned about these value dilemmas, and note their implications for future directions in research, policy, and practice.
