A Longitudinal Study of Racial Discrimination and Risk for Death Ideation in African American Youth

Although multiple studies have found that African Americans commonly experience racial discrimination, available studies have yet to examine how perceived racism might be related to suicide vulnerability in African American youth. The purpose of this study was to examine a framework for how perceived racial discrimination contributes to symptoms of depression and anxiety as well as subsequent suicide ideation and morbid ideation. Data were obtained from 722 African American youth at mean age 10.56 years (SD = 0.64); a second wave of data was obtained 2 years later. Results revealed both a direct effect and mediated effects of perceived racism on later suicide and morbid ideation. For boys and girls, the effect of perceived racism was mediated by symptoms of depression. However, the association was mediated by anxiety for girls, but not for boys in the current sample. Implications for future research and interventions are discussed.     

The Glance software package

We describe the Glance software package, which takes advantage of tablet PC technology to control experiments that require participants to reconstruct complex stimuli, as with the Chase and Simon (1973) chess reconstruction task, and to present tests that require participants to refer briefly to critical displays, as with the digit-symbol task. Participants press the space bar, which allows access to the stimulus and, simultaneously, prohibits drawing on the tablet. At release of the space bar—or optionally, after some period of time—the stimulus is hidden, and the drawing tools are enabled. Output from Glance allows analysis as fine grained as each stroke or as coarse as the entire image.     

Helping one's way to the top: self-monitors achieve status by helping others and knowing who helps whom

The authors argue that high self-monitors may be more sensitive to the status implications of social exchange and more effective in managing their exchange relations to elicit conferrals of status than low self-monitors. In a series of studies, they found that high self-monitors were more accurate in perceiving the status dynamics involved both in a set of fictitious exchange relations and in real relationships involving other members of their social group. Further, high self-monitors elevated their social status among their peers by establishing a reputation as a generous exchange partner. Specifically, they were more likely than low self-monitors to be sought out for help and to refrain from asking others for help. This behavior provides one explanation for why high self-monitors acquire elevated status among their peers--they are more attuned to status dynamics in exchange relations and adapt their behavior in ways that elicit status.     

Demonstrations of spatiotemporal integration and what they tell us about the visual system

Five sets of displays are presented on the journal website to be viewed in conjunction with the text. We concentrate on the factors that give rise to the integration and disruption of the direction of apparent motion in two-dimensional and three-dimensional space. In the first set of displays we examine what factors contribute to the integration and disruption of apparent motion in the Ramachandran/Anstis clustered bistable quartets. In the second set we examine what factors give rise to the perception of the direction of motion in rotating two-dimensional wheels and dots. In the third and fourth sets we examine how the depth cues of shading and disparity contribute to the perception of apparent motion of opaque displays, and to the perception of rotating unoccluded displays, respectively. In the fifth set we examine how the depth cue of motion parallax influences the perception of apparent motion. Throughout, we make inferences about the roles which various parallel pathways and cortical areas play in the perceptions produced by the displays shown.     

What's good for the goose may not be as good for the gander: the benefits of self-monitoring for men and women in task groups and dyadic conflicts

The authors posit that women can rely on self-monitoring to overcome negative gender stereotypes in certain performance contexts. In a study of mixed-sex task groups, the authors found that female group members who were high self-monitors were considered more influential and more valuable contributors than women who were low self-monitors. Men benefited relatively less from self-monitoring behavior. In an experimental study of dyadic negotiations, the authors found that women who were high self-monitors performed better than women who were low self-monitors, particularly when they were negotiating over a fixed pool of resources, whereas men did not benefit as much from self-monitoring. Further analyses suggest that high self-monitoring women altered their behavior in these negotiations--when their partner behaved assertively, they increased their level of assertiveness, whereas men and low self-monitoring women did not alter their behavior.     

How do we decide whom our friends are? Defining levels of friendship in Poland and the United States

Participants were 57 U.S. college students and 56 Polish university students and copper mine workers who judged the intimacy of 9 hypothetical relationships and also rated the intensity of their relationships with a best friend, a friend, and an acquaintance on the Friendship Intensity Measurement Scale (FIMS; T. S. Arunkumar & B. Dharmangadan, 2001). The present results confirmed that people perceive (a) relationships with best friends as more intense and intimate than other friendships and (b) other friendships as more intense and intimate than acquaintanceships. The results also indicated that Americans perceive all of their relationships, ranging from mere acquaintanceships to intimate friendships, as more intense and intimate than do Poles. It was somewhat surprising that there were no sex differences in either country in the perception of relationships. The authors discussed the research in the context of the difficulty of defining what friendship is and how an individual's cultural background might interact with person variables such as age and sex.     

Training to use voice onset time as a cue to talker identification induces a left-ear/right-hemisphere processing advantage

We examined the effect of perceptual training on a well-established hemispheric asymmetry in speech processing. Eighteen listeners were trained to use a within-category difference in voice onset time (VOT) to cue talker identity. Successful learners (n=8) showed faster response times for stimuli presented only to the left ear than for those presented only to the right. The development of a left-ear/right-hemisphere advantage for processing a prototypically phonetic cue supports a model of speech perception in which lateralization is driven by functional demands (talker identification vs. phonetic categorization) rather than by acoustic stimulus properties alone.     

“Why didn’t you just ask?” Underestimating the discomfort of help-seeking

Across four studies we demonstrate that people in a position to provide help tend to underestimate the role that embarrassment plays in decisions about whether or not to ask for help. As a result, potential helpers may overestimate the likelihood that people will ask for help (Studies 1 and 2). Further, helpers may be less inclined to allocate resources to underutilized support programs than help-seekers because they are less likely to attribute low levels of use to help-seekers’ concerns with embarrassment (Study 3). Finally, helpers may misjudge the most effective means of encouraging help-seeking behavior - emphasizing the practical benefits of asking for help, rather than attempting to assuage help-seekers’ feelings of discomfort (Study 4).
