Crossed-categorization, evaluation, and face recognition

We investigated the relationship between evaluative intergroup bias and biased errors in intergroup face recognition after crossed-categorization (the combination of two social categories in defining a target of perception). Although evaluative bias and recognition bias often operate in parallel, we draw on two previously unconnected literatures to predict a divergence between these two processes after crossed-categorization. We tested this hypothesis by assessing participants’ evaluations of and recognition of targets who shared two ingroups with participants, targets who shared only one ingroup with participants, and targets who shared neither ingroup. Consistent with predictions, targets’ shared and unshared group memberships combined additively to affect evaluation, but targets who shared two ingroup memberships were better recognized than all other category combinations. These results document the relationship between evaluative bias and recognition bias after crossed-categorization and indicate that crossed-categorization affects evaluative bias and recognition bias in different ways.     

Visual discrimination learning in rats with lesions of superior colliculus: Door-push and approach errors in modified jumping stand

It has been suggested that, for some species, lesions of the superior colliculus affect visual discrimination learning, but only in certain conditions: (a) when problems are first learnt only after operation, or (b) when discriminanda require detailed scanning, or (c) when “approach” responses to the discriminanda are measured, rather than the response of actually touching them. These suggestions were examined in rats learning visual discriminations in a modified jumping-stand apparatus, after sustaining large lesions of the superior colliculus (and in some cases also of the pretectum). The lesions produced open-field hyperactivity and reduced exploration, indicating effective tectal damage, but the rats learnt a series of difficult discriminations in a door-push task as fast as normal rats, and they did not make more approach errors. Their main abnormality in the discrimination apparatus was that they looked less often between the stimulus doors before stepping across to one of them from the central platform. It is suggested that in rats, as in other animals, lesions of the superior colliculus disrupt the control of scanning head and eye movements; in rats, however, such disruption need not affect discrimination learning (at least in some kinds of apparatus), possibly because the retina of the rat has a relatively poorly developed area centralis.     

Beliefs as inner causes: The (lack of) evidence

Many psychologists studying lay belief attribution and behavior explanation cite Donald Davidson in support of their assumption that people construe beliefs as inner causes. But Davidson’s influential argument is unsound; there are no objective grounds for the intuition that the folk construe beliefs as inner causes that produce behavior. Indeed, recent experimental work by Ian Apperly, Bertram Malle, Henry Wellman, and Tania Lombrozo provides an empirical framework that accords well with Gilbert Ryle’s alternative thesis that the folk construe beliefs as patterns of living that contextualize behavior.     

Gaming motivation and problematic video gaming: The role of needs frustration

Motivation is often used as a predictor of a problematic style of video game engagement, implying that individuals' gaming undermines optimal functioning. Drawing from recent advances in Self‐Determination Theory (SDT), the present study explores the links between gaming motivations, the daily frustration of basic psychological needs, and reports of problematic video gaming (PVG). A sample of 1029 participants (72.8% male; M = 22.96 years; SD = 4.13 years) completed items regarding their gaming engagement and gaming motivation as well as their experience of needs frustration and PVG symptoms. Results revealed positive associations between gaming motivations and PVG, and between daily needs frustration and PVG. Finally, after comparing several competing models, a mediational model whereby needs frustration explained the association between individuals' gaming motivation and PVG emerged as best fitting the data. The discussion addresses the theoretical and practical implications of these findings in the context of recent research.     

A Qualitative Examination of the Relationship Between Body Image and Sexual Behavior: Perceptions from Latina and African American Adolescent Girls and Their Maternal Caregivers

Although prior work suggests that how adolescent girls feel about their body is associated with their sexual behavior, we have less insight into the reasons why. We conducted semi-structured interviews with 25 African American adolescent girls (11–14 years of age), 18 Latina adolescents (14–17 years of age), and their maternal caregivers to explore why this association may exist. Both adolescent girls and their maternal caregivers were asked “Who is more likely to have sex, a girl who likes the way her body looks or a girl who doesn’t like the way her body looks?” A similar question was asked about condom use. Interviews were digitally recorded, transcribed, and coded for emergent themes using thematic analysis. Participants’ responded that both girls with a positive body image and those with a negative body image may be likely to have sex because of self- and body-esteem. Two sub-themes emerged that further explained why low self- and body-esteem mattered for girls who have a negative perception of their body: (a) feeling appreciated (b) easily persuaded. Most participants noted that girls with a positive body image perception would be more likely to use condoms. Emergent themes for using condoms were: (a) pregnancy/STI protection; and (b) body preservation. Our findings have implications for empirically exploring the pathways through which body image perceptions relate to adolescent sexual behaviors, and the possibility that universal prevention programs may not resonate similarly for all adolescent girls.     

Fifteen Years of the Journal of Multicultural Counseling and Development: A Content Analysis

The authors present the results of a content analysis of articles that were published in the Journal of Multicultural Counseling and Development (JMCD) during the last 15 years. The analysis identified the leading contributors (i.e., authors, institutions) to JMCD, evaluated the content of the articles, examined the type of articles, and highlighted the particular cultural groups that were studied most frequently. Los autores presentan los resultados de un análisis de el contenido de la Revista de Consejeria y Desarrollo Multicultural (JMCD), durante los ultimos 15 años. El análisis identificó los contribuyentes más destacados (en otras palabras, los autores, las instituciones) a JMCD; examinó el tipo del articulos y subrayó los grupos culturales que se estudiaron más frecuentemente.     

Velocity perception for sounds moving in frequency space

In three experiments, we considered the relative contribution of frequency change (Δf) and time change (Δt) to perceived velocity (Δf/Δt) for sounds that moved either continuously in frequency space (Experiment 1) or in discrete steps (Experiments 2 and 3). In all the experiments, participants estimated “how quickly stimuli changed in pitch” on a scale ranging from 0 (not changing at all) to 100 (changing very quickly). Objective frequency velocity was specified in terms of semitones per second (ST/s), with ascending and descending stimuli presented on each trial at one of seven velocities (2, 4, 6, 8, 10, 12, and 14 ST/s). Separate contributions of frequency change (Δf) and time change (Δt) to perceived velocity were assessed by holding total Δt constant and varying Δf or vice versa. For tone glides that moved continuously in frequency space, both Δf and Δt cues contributed approximately equally to perceived velocity. For tone sequences, in contrast, perceived velocity was based almost entirely on Δt, with surprisingly little contribution from Δf. Experiment 3 considered separate judgments about Δf and Δt in order to rule out the possibility that the results of Experiment 2 were due to the inability to judge frequency change in tone sequences.     

Connecting Youth Violence Prevention, Positive Youth Development, and Community Mobilization

Several disconnects serve to weaken the use of evidence based programming in community settings. Communities face the need to address the challenges of multiple risk behaviors faced by adolescents in their communities, but must also work to support successful transitions to adulthood and the broader positive development of their youth. The stronger integration of positive youth development and prevention of youth risk at the community level may offer an opportunity to support the implementation and ongoing development of evidence-based practices (EBPs). This article provides an overview of the VCU Clark-Hill Institute for Positive Youth Development Institute's community mobilization effort in Richmond, Virginia and reports preliminary findings from our integrated mobilization efforts. First, we review the role of our Community Advisory Council in their collaborative work to support positive youth development and reduce risk for youth violence. Next, we present examples of institute efforts in providing technical assistance relevant to supporting the use and development of EBPs. We then discuss the adaptation of an evidence-based program to target positive youth development. We also present overviews from qualitative investigations examining barriers and supports that inform and are relevant to the implementation of EBPs. Finally, we consider ways in which community efforts inform and shape institute efforts to develop EPBs. Taken together, these activities provide examples of how community-based mobilization efforts can integrate and inform the implementation of EBPs and the role and use of prevention science as a tool in supporting effective programming to promote positive youth development and prevent youth violence.
