Brain stem electrical responses of stutterers and normals by sex,ears, and recovery

Auditory brainstem electrical responses (BSER) of right and left ears of active stutterers, recovered stutterers, and nonstutterers, both male and female adults, were obtained at click rates of 11.1 and 71.1/sec. Latency intervals of waves I, III, and V were measured. The auditory systems of subjects were stressed using a rapid rate of 71.1 clicks/sec. The latency of wave V was used as the measure of the stress condition.Analysis of variance was used to determine statistical significances of main effects and interactions of mean BSER (waves I, III, V, and wave V in stress condition) of left and right ears of male stutterers (active and recovered), female stutterers (active and recovered), and male and female nonstutterers.With one exception, all main effects and all higher order interactions were nonsignificant. The one main effect that was significant was gender. Females have significantly faster rates of neural transmission than do males. The question was raised, does this finding contribute toward an explanation of the sex ratio in stuttering?     

Gender and leadership emergence: A meta‐analysis and explanatory model

Research has shown that men tend to emerge as leaders more frequently than women. However, societal role expectations for both women and leaders have changed in the decades since the last empirical review of the gender gap in leader emergence (Eagly & Karau, 1991). We leverage meta‐analytic evidence to demonstrate that the gender gap has decreased over time, but a contemporary gap remains. To understand why this gap in leader emergence occurs, we draw on social role theory to develop a Gender‐Agency/Communion‐Participation (GAP) Model—an integrative theoretical model that includes both trait and behavioral mechanisms. Specifically, we examine a sequence of effects: from gender to agentic and communal personality traits, from these traits to behavioral participation in group activities, and ultimately from participation to leader emergence. The model is tested using original meta‐analyses of the personality and behavioral mechanisms (coding 1,632 effect sizes total). Gender differences in leadership emergence are predominately explained by agentic traits (positive) and communal traits (negative), both directly and through the mechanism of participation in group discussions. In addition, several paths in the theoretical model are moderated by situational contingencies. Our study enhances knowledge of the mechanisms and boundary conditions underlying the gender gap in leader emergence.     

Staff Practices and Social Skill Outcomes in a Sport-Based Youth Program

Staff are key contributors to quality sport-based youth programming. Specific practices leading to positive youth outcomes warrant further investigation. This study examined social skill outcomes resulting from participation in a sport-based youth program, LiFEsports. In addition, relationships among emotional and autonomy supportive staff practices and outcomes were examined. Results pointed to the value of sport-based youth programs for promoting self-control among youth from vulnerable backgrounds and indicated that youth-perceived emotional and autonomy supportive staff practices predicted improvements in perceived self-control but not perceived externalizing behaviors.     

Male callers to an Australian perinatal depression and anxiety help line—Understanding issues and concerns

There is increasing recognition of the issues facing men in the perinatal period. Vulnerability factors and issues in the partner relationship contribute to mental health risk and can impact the quality of the father–infant relationship. Yet, there is limited understanding of fathers’ help-seeking when they or their partner are experiencing mental health issues in the context of caring for a new baby. The present study examines fathers’ contacts with the Perinatal Anxiety and Depression Australia (PANDA) National Helpline. The study reviewed contacts from fathers and their identified needs for assistance, relationship issues, and support needs; 70% of male callers (N = 129) reported concerns about the mother's mental health, and 57% were concerned about relationship breakdown. Significant numbers of men raised issues about their own mental health (43%) and many were concerned about the impact of maternal mental state on the relationship with the infant. When compared to community data, there were elevated rates of concerns about depression and anxiety. Men also described difficulties with the fathering role and with regulating their own feelings of guilt and frustration. These findings highlight the needs of men for support when a mother experiences perinatal problems and also the risk for distress in fathers.     

Truthiness and law: Nonprobative photos bias perceived credibility in forensic contexts

Nonprobative but related photos can increase the perceived truth value of statements relative to when no photo is presented (truthiness). In two experiments, we tested whether truthiness generalizes to credibility judgments in a forensic context. Participants read short vignettes in which a witness viewed an offence. The vignettes were presented with or without a nonprobative, but related photo. In both experiments, participants gave higher witness credibility ratings to photo-present vignettes compared to photo-absent vignettes. In Experiment 2, half the vignettes included additional nonprobative information in the form of text. We replicated the photo presence effect in Experiment 2, but the nonprobative text did not significantly alter witness credibility. The results suggest that nonprobative photos can increase the perceived credibility of witnesses in legal contexts.     

Innovation in therapeutic practice with ‘violent youth’: A discourse analysis of the non‐violent resistance approach

Introduction: The introduction of the innovative non‐violent resistance approach (NVR) at a multi‐agency service in east Kent, UK, has presented challenges in terms of the recruitment of the necessary wider professional support for the family, with some professionals seeing the approach as not child‐focused. Aims and objectives: To identify child‐focused themes among professionals, and to compare these with discourses used in NVR and, for comparison, in the Webster‐Stratton approach, to elucidate possible obstacles to the acceptance by professionals of NVR. Methods and analysis: A focus group of experienced professionals was convened to discuss what it means to be child‐focused, and a thematic analysis was conducted. Key texts from NVR and the Webster‐Stratton approach were selected and analysed using Foucauldian discourse analysis. Results: Being child‐focused was considered to require the child's voice being heard, at least by the parents. Power differentials and developmental issues were also highlighted in the discussion. The key text analyses suggests that the Webster‐Stratton approach is communicated through familiar ‘biomedical’ and ‘missionary’ discourses, while surprisingly NVR is communicated through a discourse of ‘war’ as well as the more familiar and child‐focused ‘family values’ discourse. Implications: The ‘war’ discourse used by NVR, in which violent young people are seen as aggressors and oppressors, challenges the traditional discourses of childhood formed around notions of innocence. The implications of these findings are discussed in relation to furthering the adoption of NVR as an effective way of working to help violent children of all ages.     

A neural network model of retrieval-induced forgetting

Retrieval-induced forgetting (RIF) refers to the finding that retrieving a memory can impair subsequent recall of related memories. Here, the authors present a new model of how the brain gives rise to RIF in both semantic and episodic memory. The core of the model is a recently developed neural network learning algorithm that leverages regular oscillations in feedback inhibition to strengthen weak parts of target memories and to weaken competing memories. The authors use the model to address several puzzling findings relating to RIF, including why retrieval practice leads to more forgetting than simply presenting the target item, how RIF is affected by the strength of competing memories and the strength of the target (to-be-retrieved) memory, and why RIF sometimes generalizes to independent cues and sometimes does not. For all of these questions, the authors show that the model can account for existing results, and they generate novel predictions regarding boundary conditions on these results.     

Racial groups and test fairness, considering history and construct validity

According to Helms, "test fairness" is defined as "removal from test scores of systematic variance attributable to experiences of racial or cultural socialization." Some of Helms's reasoning is based on earlier work, which recommended that racial group or category variables be replaced entirely with individual-level constructs, to reflect racial socialization experiences that vary within racial groups. Treatment of the test fairness issue--a social and political issue--will benefit from explicitly considering historical events that contributed to group-level race differences. In light of this history, D. A. Newman et al suggest (a) retaining a group-level conceptualization of race/racial socialization and also (b) focusing on criterion-irrelevant variance in test scores that is attributable to race.
