An aftereffect in judgment of auditory duration

Two experiments were designed to investigate the occurrence of atemporal aftereffect following auditory spatial stimulation. The task required Ss to compare by means of a motorresponse the duration of a test tone presented at a variable interval after stimulation with a standard tone. In both experiments the posttest duration was underestimated relative to the pretest duration, i.e., there was a temporal aftereffect(TAE). A control experiment which involved Ss making estimates of the duration of the test tones, without the presentation of interpolated standard tones, did not show this effect. The temporal aftereffect followed a function analogous to the “distance paradox” forspatial aftereffects.     

Social Dominance Orientation and the Ideological Legitimization of Social Policy1

Much of politics is involved with the distribution of resources and the regulation of intergroup relations. Social dominance theory posits that social ideologies provide social justification for policies that have unequal effects on different social groups. In the present studies, we examine the mediating role that ideologies have in transforming people's general orientation toward group inequality into policy support. Using data from 5 samples, we offer evidence that social dominance orientation orients people to support discriminatory ideologies, which in turn influence support for policies. Support for the theoretical model was shown in studies of both long-standing social policy attitudes, such as toward social welfare and military programs, and of unfolding political events, including Clarence Thomas' nomination to the Supreme Court, the Persian Gulf War, and reinstitution of the death penalty in California.     

The effectiveness of unitization in mitigating age-related relational learning impairments depends on existing cognitive status

Binding relations among items in the transverse patterning (TP) task is dependent on the integrity of the hippocampus and its extended network. Older adults have impaired TP learning, corresponding to age-related reductions in hippocampal volumes. Unitization is a training strategy that can mitigate TP impairments in amnesia by reducing reliance on hippocampal-dependent relational binding and increasing reliance on fused representations. Here we examined whether healthy older adults and those showing early signs of cognitive decline would also benefit from unitization. Although both groups of older adults had neuropsychological performance within the healthy range, their TP learning differed both under standard and unitized training conditions. Healthy older adults with impaired TP learning under standard training benefited from unitized training. Older adults who failed the Montreal Cognitive Assessment (MoCA) showed greater impairments under standard conditions, and showed no evidence of improvement with unitization. These individuals’ failures to benefit from unitization may be a consequence of early deficits not seen in older adults who pass the MoCA.     

Meaning in the Lives of Caregivers of Individuals with Parkinson's Disease

This study explores the contribution of finding meaning in general and finding meaning specific to caregiving as potentially important explanatory variables in predicting well-being in caregivers of individuals with Parkinson's disease. Fifty-eight caregivers of individuals diagnosed with Parkinson's disease were provided self-report questionnaires to assess well-being and meaning (general and specific). Results showed a significant proportion of the variance of positive affect (PASS) and negative affect (DYS) related to well-being, as assessed by the Multiple Affect Adjective Checklist – Revised. Purpose and Existential Vacuum (two subtests of the Life Attitude Profile – Revised used to assess general meaning) predicted well-being. Purpose predicted 41.8% of the variance related to PASS; Existential Vacuum predicted 30.8% of the variance related to DYS. Meaning related specifically to caregiving (Finding Meaning Through Caregiving Scale) did not explain any additional variance. Our results suggest that finding meaning, beyond meaning specifically associated with caregiving, is the key to understanding well-being among caregivers of individuals with Parkinson's disease. The positive construct of finding meaning in general can empower researchers and professionals working with caregivers to better understand the variability in caregiver outcomes as well as assess and intervene more effectively.     

Initial Development of a Gendered-Racial Socialization Scale for African American College Women

As research exploring the racial-ethnic socialization practices of African American families continues to expand, scholars have argued for a more multidimensional approach in the measurement of racial-ethnic socialization that focuses on the influence that youths’ gender may have on the messages families provide. Although studies have used current racial-ethnic socialization measures to examine gender differences in the messages youth receive, these studies are limited in investigating intersectional messages that African American girls and women receive regarding racial and gender identities. The present preliminary study sought to address this inadequacy by developing the Gendered Racial-Ethnic Socialization Scale for Black Women (GRESS-BW), a scale that accounts for the unique messages African American young women receive regarding their intersectional identities. Utilizing a sample of 174 African American college women, Exploratory Factor Analysis indicated that the GRESS-BW consisted of 63 items with a 9-factor solution. There was strong internal consistency for the GRESS-BW factors and the total scale. GRESS-BW construct validity assessment revealed that several of the factors were significantly positively related to a racial-ethnic socialization scale. However, only two components were significantly related to a gender-role socialization measure. Clinical and research implications are discussed.     

A music-based HIV prevention intervention for urban adolescents

OBJECTIVE: This research examines the process of conducting and evaluating a music-based HIV prevention intervention among urban adolescents, and is informed by the information, motivation, behavioral skills (IMB) model. DESIGN: Musically talented opinion leaders were recruited to write, record, and distribute HIV prevention themed music to their peers to increase HIV prevention motivation, behavioral skills, and behaviors. In this 3-month field experiment, participants were 306 students enrolled in health classes at each of three large multiracial urban high schools (one treatment school; two control schools). MAIN OUTCOME MEASURES: Measures of HIV prevention information, motivation, behavioral skills, and behaviors, both pre- and postintervention. RESULTS AND CONCLUSION: Results indicate that the intervention influenced several aspects of HIV prevention motivation, behavioral skills, and condom use and HIV testing behaviors. This research demonstrates that the incorporation of music into HIV prevention interventions for adolescents has the potential to be effective.
