Influence of African American elders’ age stereotypes on their cardiovascular response to stress

Abstract

Although it has been shown that White elders are vulnerable to the influence of age stereotypes, it was not known whether this effect applied to African American elders. In the present study, African American elders were randomly assigned to negative or positive implicit-age-stereotype groups. Compared to participants in the positive age-stereotype group, those in the negative age-stereotype group demonstrated significantly more elevated cardiovascular response to stress, as measured by blood pressure and heart rate following mental challenges. These results suggest that negative age stereotypes generate a susceptibility to stress among African American elders, whereas positive age may provide them with a defense against this stress.     

Sexual Prejudice among Christian College Students, Denominational Teachings, and Personal Religious Beliefs

Although numerous studies have examined the role of religious tradition and religiosity on attitudes toward lesbian, gay, and bisexual people, the role of endorsement of denominational teachings has largely been overlooked, even though such teachings are often cited to explain study findings. To better understand the complex relationship between religion and sexual prejudice, this study explores the unique contributions of religious tradition, religiosity, and individual endorsement of denominational doctrine about same-sex sexuality in shaping these attitudes. Findings indicate that endorsement of denominational doctrine concerning same-sex sexuality is more influential than religiosity, and that endorsement of denominational doctrine is not simply a proxy for believing that same-sex sexuality is a sin. Implications for future research are discussed.     

Preschoolers' Recall of Own-Sex and Other-Sex Gender Scripts

A sample of 486 children in Beijing, China, were tested on the water-level task (WLT; J. Piaget &; B. Inhelder, 1948/1956). The participants were 256 boys and 230 girls from 4th, 5th, 6th, 8th, and 11th grades. Three levels of mastery of the WLT were found. Level 1 consisted of 4th and 5th graders, who averaged about 71% correct. Level 2 consisted of 6th and 8th graders, who averaged about 83% correct. Level 3 consisted of 11th graders, who averaged 97% correct. The results provide partial support for the Piagetian theory of age-related developmental differences in performance on the WLT. The findings depict an interactive relationship of maturation with culture and education in the development of the ability to solve the WLT.     

A whole face is more than the sum of its halves: Interactive processing in face perception

Facial information is processed interactively. Yet, such interactive processing has been examined for discrimination of face parts rather than complete faces. Here we assess interactive processing using a novel paradigm in which subjects discriminate complete faces. Face stimuli, which comprise unilateral facial information (hemifaces) or bilateral facial information from one face (consistent) or two different faces (inconsistent), are shown centrally in a face‐matching task. If each half of a complete face is processed independently, accuracy for complete faces can be predicted by the union of accuracies for right and left hemifaces. However, accuracy exceeded this independence prediction for consistent faces (facilitation) and fell below the prediction for inconsistent faces (interference). These effects were reduced or absent for inverted faces. Our findings are consistent with reports of stronger interactive processing for upright than for inverted faces and they quantify effects of interactive processing on the discrimination of complete faces.     

Job Demand–Control–Support and diabetes risk: The moderating role of self-efficacy

Work-related stressors, including high demands and low control, play a significant role in the aetiology of diabetes. Nevertheless, most studies focus on main effects, and few consider individual differences that may moderate the stress–health association. Drawing from the Job Demands–Control-–Support (JDC-S) model, this study addresses this gap by testing how baseline levels of JDC-S affect an increase in two risk factors for diabetes—glycated haemoglobin (HbA1C) and fasting plasma glucose (FPG)—and by investigating the moderating role of self-efficacy. Participants (N = 1618) were Israeli employees who attended two consecutive routine health examinations. All were free of diabetes at baseline. JDC-S and self-efficacy were assessed at baseline (T1), and HbA1C and FPG were assessed at T1 and T2. Data were analysed with logistic and linear regressions, controlling for well-established diabetes risk factors. High demands and low support predicted an increase in HbA1C and FPG. In addition, high self-efficacy interacted with high demands and with low control in the prediction of an increase in HbA1C and FPG. Although employees with high self-efficacy might function well at work, overloading them may harm their physical health. Similarly, incongruence between employees’ sense of ability and the control given to them at work may result in physical impairment.     

Probing the Brain Substrates of Cognitive Processes Responsible for Context Effects on Recognition Memory

ABSTRACT

Context effects on episodic recognition memory involve separable contributions of target-context binding, additive familiarity, and configural constancy. Here we examine whether these factors reflect contributions of processes attributed to different brain substrates. First, we challenged frontal and medial temporal lobe-based cognitive capacities in healthy young adults, employing divided attention tasks at encoding and retrieval, and extended retrieval delay, respectively. Target-context binding effects were specifically attenuated by delay, but not by divided attention. In a second experiment, older adults were identified by neuropsychological testing as having different levels of frontal and medial temporal lobe-dependent cognitive functions. Consistent with Experiment 1, older adults with low medial temporal lobe function exhibited reduced target-context binding effects, but levels of frontal function did not modulate binding effects. These findings indicate that unlike source memory, context effects on memory are associated with the integrity of medial temporal lobe-based processes but not with the integrity of frontal lobe-based processes. Our findings also emphasize the importance of discriminating between functional subgroups in the attempt to characterize memory processes in older adults.

In the opening section of this paper we spell out an account of our naïve view of bodily sensations that is of historical and philosophical significance. This account of our shared view of bodily sensations captures common ground between Descartes, who endorses an error theory regarding our everyday thinking about bodily sensations, and Berkeley, who is more sympathetic with common sense. In the second part of the paper we develop an alternative to this account and discuss what is at stake in deciding between these two ways of understanding our everyday view. In the third and final part of the paper we offer an argument in favour of our alternative.     

Thinking about Mutual Influences and Connections across Cultures Relates to More Positive Intergroup Attitudes: An Examination of Polyculturalism

Polyculturalism is an ideology focusing on the many ways that racial and ethnic groups have interacted, exchanged ideas, and influenced each other's cultures throughout history and into the present. In this paper, we first briefly review the introduction of and research on polyculturalism by historians. Then we summarize numerous studies with racially and ethnic diverse college students and adult community members in the United States, which have found that greater endorsement of polyculturalism is significantly associated with more positive racial/ethnic intergroup attitudes (less support for social inequality, greater interest in, appreciation for, and comfort with diversity and differences, greater interest in intergroup contact, and greater support for liberal immigration and affirmative action policies) and lower sexual prejudice (lower affective prejudice toward gay men and lesbians, traditional heterosexism, and denial of discrimination against homosexuals, and more positive attitudes toward gay men and lesbians). We conclude by discussing several future directions of this work.     

Suppression-induced forgetting on a free-association test

The repeated suppression of thoughts in response to cues for their expression leads to forgetting on a subsequent test of cued recall (Anderson & Green, 2001). We extended this effect by using homograph cues and presenting them for free association following suppression practice. Cue–target pairs were first learned under integrating imagery instructions; then in the think/no-think phase students practised suppressing thoughts connected to some homograph cues, with or without the assistance of thought substitutes that changed their meaning. Below-baseline forgetting on the subsequent free-association test was found in the production of suppressed targets. Following aided suppression this effect was also obtained in the production of other responses denoting the target-related meaning of the homograph cues. Discussion emphasises the ecological value of the test; rarely do people deliberately attempt recall of unwanted thoughts.
