Examining a community intervention to help White people understand race and racism and engage in anti-racist behaviours

Uprisings over the past decade have accelerated the search for interventions to support White people in increasing their capacity to understand historical and present-day racial dynamics. This study investigates the impacts and effectiveness of a community-led intervention developed to prime White individuals to challenge injustice through increasing knowledge, confidence, and competence related to race, racism, intragroup dialogue, and colour-blind racial attitudes. Five hundred and thirty seven participants were recruited from four cohorts of community-led groups, which read, reflected, journaled, and completed activities related to race and racism for a total of 40 hr over 10 sessions. Participants were given pre- and post-measures to assess their White racial capacity, and colour-blind racial attitudes. Participants also completed a follow-up assessment on anti-racist behaviours. The results indicated that participants were able to increase their racial capacity in terms of their understanding and knowledge of race and racism. They also indicated that they felt more confident and competent to have racial discussions in an intergroup context. The possibilities and limitations of interventions to shift attitudes and behaviours are discussed.     

Contrast discrimination in human infants

The ability to detect differences in spatial contrast is crucial to object recognition and identification. This ability is generally examined by measuring the contrast discrimination function. This function represents, for a variety of conditions, the smallest contrast difference required to discriminate otherwise identical patterns. We examined human infants' ability to discriminate patterns on the basis of differences in spatial contrast. The forced-choice preferential looking procedure was used to estimate contrast increment thresholds at a number of background contrasts. The Weber fractions of 6- and 12-week-old infants were about 1 log unit higher than adult values for background contrasts ranging from 0.14 to 0.55. Furthermore, the slopes of infants' discrimination functions were much shallower than those of adults. These age differences in contrast discrimination imply certain changes in the neural mechanisms that underlie contrast encoding. They also aid our understanding of the anomalies observed in early pattern vision.     

The development of contrast constancy

The mature visual system possesses mechanisms that enable invariant perception of the contrast of an object and its features as the object undergoes changes in distance. This phenomenon, which has been called contrast constancy, obtains at suprathreshold contrasts only. Some models of contrast constancy assume the presence of narrowband spatial-frequency channels. An implication of M.S. Banks, B.R. Stephens, and E.E. Hartmann (1985, Journal of Experimental Child Psychology, 40, 501-527) is that contrast constancy should not be observed at 6 weeks but may be observed at 12 weeks. We examined this implication by investigating the development of contrast constancy in 6- and 12-week-old infants. Two sine wave gratings, differing in spatial frequency by a factor of 3, were presented side-by-side. The contrast of one grating was varied in order to estimate the contrast at which preference for the two gratings was equal. The equal preference points for 6-week-olds were predictable from their contrast thresholds. The 12-week-olds' equal preference points for low-contrast stimuli were predictable from their contrast thresholds, but those for intermediate and high-contrast stimuli were not. Thus, if one accepts the assumption that equal preference in infants is analogous to apparent contrast matches in adults, these data imply that contrast constancy is observed at 12 weeks but not 6 weeks. The perceptual consequences of this developmental transition are discussed.     

A meta-analysis of the Dark Triad and work behavior: a social exchange perspective

We reviewed studies of the Dark Triad (DT) personality traits--Machiavellianism, narcissism, and psychopathy-and meta-analytically examined their implications for job performance and counterproductive work behavior (CWB). Relations among the DT traits and behaviors were extracted from original reports published between 1951 and 2011 of 245 independent samples (N = 43,907). We found that reductions in the quality of job performance were consistently associated with increases in Machiavellianism and psychopathy and that CWB was associated with increases in all 3 components of the DT, but that these associations were moderated by such contextual factors as authority and culture. Multivariate analyses demonstrated that the DT explains moderate amounts of the variance in counterproductivity, but not job performance. The results showed that the 3 traits are positively related to one another but are sufficiently distinctive to warrant theoretical and empirical partitioning.     

Sleep deprivation and stressors: Evidence for elevated negative affect in response to mild stressors when sleep deprived

Stress often co-occurs with inadequate sleep duration, and both are believed to impact mood and emotion. It is not yet known whether inadequate sleep simply increases the intensity of subsequent stress responses or interacts with stressors in more complicated ways. To address this issue, we investigated the effects of one night of total sleep deprivation on subjective stress and mood in response to low-stress and high-stress cognitive testing conditions in healthy adult volunteers in two separate experiments (total N = 53). Sleep was manipulated in a controlled, laboratory setting and stressor intensity was manipulated by changing difficulty of cognitive tasks, time pressure, and feedback about performance. Sleep-deprived participants reported greater subjective stress, anxiety, and anger than rested controls following exposure to the low-stressor condition, but not in response to the high-stressor condition, which elevated negative mood and stress about equally for both sleep conditions. These results suggest that sleep deprivation lowers the psychological threshold for the perception of stress from cognitive demands but does not selectively increase the magnitude of negative affect in response to high-stress performance demands.

Counselors' Attitudes Toward Domestic Violence in Same‐Sex Versus Opposite‐Sex Relationships

Domestic violence is often perceived to occur only in heterosexual relationships. However, domestic violence is also prevalent in same‐sex relationships. The majority of the research indicates that counselors perceive same‐sex domestic violence differently than heterosexual domestic violence. This literature review synthesizes the research investigating attitudes toward same‐sex domestic violence. La violencia doméstica se suele percibir como un evento que ocurre solamente en las relaciones heterosexuales. Sin embargo, la violencia doméstica también es prevalente en relaciones del mismo sexo. La mayor parte de las investigaciones indican que los consejeros perciben la violencia doméstica entre personas del mismo sexo de forma diferente a como perciben la violencia doméstica heterosexual. Esta reseña de la literatura sintetiza las investigaciones que tratan sobre las actitudes hacia la violencia doméstica entre personas del mismo sexo.     

Emotional Rescue: How Affect Helps Partisans Overcome Collective Action Problems

Why does party identification motivate citizens to participate in politics? From a theoretical standpoint, it is in a partisan's self‐interest to free ride on the efforts of others. Yet, mere identification with a party is enough to motivate many people to overcome this structural hurdle. We theorize that, by virtue of aligning one's self with a party, individuals become more likely to react to their political environment with anger and enthusiasm rather than fear. Anger and enthusiasm are associated with approach and continuation of current behavior, while fear triggers behavior reconsideration. In short, party identification stimulates participation via anger and enthusiasm. On the other hand, fear produces thought but not much action. We find support for our model using data from the American National Election Studies (ANES) and an original laboratory experiment.
