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.     

Allocentric versus idiocentric tendencies: Convergent and discriminant validation

Allocentric tendencies were studied with a multimethod questionnaire and Illinois undergraduates. Nine scales measuring different aspects of allocentrism were shown to have good reliability and to be intercorrelated, thus showing convergent validity. Factor analysis identified three aspects: subordination of personal to group goals, the ingroup as extension of the self, and ingroup identity. The scales also had satisfactory discriminant validity. Those high on idiocentric tendencies used equity and those high in allocentric tendencies used equality and need in distributing rewards. A second study found that those who are allocentric are more likely to emphasize the values of cooperation, equality, and honesty, and those who are idiocentric to emphasize the values of comfortable life, competition, pleasure, and social recognition. Those who were allocentric reported receiving more social support and a better quality of social support; those who were idiocentric were higher in achievement motivation, alienation, anomie, and reported greater loneliness.     

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.     

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.
