Aging and Working Memory Inside and Outside the Focus of Attention: Dissociations of Availability and Accessibility

ABSTRACT

Two experiments used the N-Back task to test for age differences in working memory inside and outside the focus of attention. Manipulations of the difficulty of item-context binding (Experiment 1) and of stimulus feature binding (Experiment 2) were used to create conditions that varied in their demand on working memory, with the expectation that greater demand might increase age differences in focus-switching costs and the search rate outside the focus of attention. Results showed, however, that although age differences were evident in measures of overall speed and accuracy, and the manipulations significantly affected response times and accuracy in the expected direction, the experimental manipulations had no impact on age differences. Findings instead pointed to age-related reductions in accuracy but not speed of focus-switching and search outside the focus of attention. Thus, age-related deficits appear to involve the availability of representations in working memory, but not their accessibility.     

African American cultural history and reflections on Jung in the African Diaspora

Racism is defined as a psychopathology and the ground in which the covenant of whiteness is rooted and mirrored in the system of apartheid structured by American Constitutional Jurisprudence between 1857 and 1954. This historical period overshadowed Carl Jung's visit to America between 1909 and 1937. The spirit of the times and practices of racism coloured Jung's views, attitudes, and theories about African Americans, just as colonialism coloured his attitudes toward Africa and Africans. Consequently Jung failed to see the African Diaspora and the extraordinary intellectual and artistic period of the Harlem Renaissance (1919‐1929). Its introduction here foregrounds the exceptionalism of African Americans and the cultural continuity of African ancestry. This exceptionalism was not seen by Jung and there have been no attempts to redress its omission from analytical psychology and other sub‐disciplines of Western psychology. Jung's theories of personality and psychoanalysis and his negative projections about primitivism among Africans and African American ‘Negroes’ would have been mediated by knowledge of a legislated American apartheid and the Harlem Renaissance which occurred within the barriers of apartheid. In this paper I posit that culture, kinship libido, and the African principle of Ubuntu are healing modalities that play a critical role in instinct and the relational ground of human psychology and biology, from which culture as an environmental expression constellates around common goals of the human species. Cultural equivalencies and expressions within the wisdom traditions and mythologies of the Africa Diaspora are considered. Specifically, the Bantu principle of Ubuntu or ‘humanity’ is identified as the relational ground in African cultures, while the Kemetic‐Egyptian deity Maat, as an archetypal anima figure and the religio‐mythology offer a transcendent position from which to critique the inequities and constitutional jurisprudence that structured American apartheid. Maat is the personification of truth, justice, balance and weighing of the heart in orderly judicial processes. In her we find the alignment of the spirit and matter in the law and judgement. The paper concludes with reflections on pathways toward healing the psychopathology of racism and recommendations to enhance clinical training and practice.     

Racial/ethnic differences in Body Mass Index: the roles of beliefs about thinness and dietary restriction

The greater BMI of African American relative to Caucasian women is implicated in racial/ethnic disparities in health outcomes. The principal aim of the current study was to evaluate a theoretical account of racial/ethnic differences in BMI. Thin-ideal internalization, the perceived romantic appeal of thinness, dietary restriction, weight, and height were assessed via self-report measures on a sample of female undergraduates of African American (n = 140) and Caucasian (n = 676) race/ethnicity. Using structural equation modeling, support was obtained for the primary hypothesis that racial/ethnic differences in BMI are explained by Caucasian women's greater thin-ideal internalization and perceived romantic appeal of thinness, thereby resulting in greater levels of dietary restriction. Current findings illustrate the potential for racial/ethnic differences in sociocultural standards of appearance to influence racial/ethnic disparities in physical health, of which BMI is a marker, via effects on weight control behavior.

Self-Esteem Instability and Humor Styles: Does the Stability of Self-Esteem Influence How People Use Humor?

The purpose of the present study was to examine whether self-esteem instability moderated the association between self-esteem level and the use of humor. This was accomplished by examining the associations that humor styles had with self-esteem level and self-esteem instability among 499 undergraduates. The results of the present study show that self-esteem instability moderated the association between self-esteem level and humor styles such that individuals with stable high self-esteem reported the highest levels of affiliative humor as well as the lowest levels of aggressive and self-defeating humor. These results suggest that individuals with stable and unstable forms of self-esteem employ different styles of humor.
