Effects of racial prejudice and race of target on aggression

Three studies were conducted to investigate the relationship between prejudice and physical aggression using the competitive reaction time paradigm. In Study 1, high and low prejudiced subjects competed against either a black or white opponent. The race of the opponent did not differentially affect the aggressive behavior of either high or low prejudiced subjects. In Study 2, high prejudiced subjects were confronted with a competitor who behaved in a nonaggressive fashion. Under these conditions, the high prejudiced subjects attacked the black target more than the white target. In Study 3, high prejudiced subjects competed against an opponent who communicated nonaggressive intentions. The subjects behaved in a nonaggressive manner toward both the black and the white target. It was proposed that prejudice facilitates indiscriminate aggression in the presence of a clear threat and selective aggression in the presence of ambiguous threat.     

Quasi-Indexicals and Knowledge Reports

We present a computational analysis of de re, de dicto, and de se belief and knowledge reports. Our analysis solves a problem first observed by Hector-Neri Castaneda, namely, that the simple rule '(A knows that P) implies P' apparently does not hold if P contains a quasi-indexical. We present a single rule, in the context of a knowledge-representation and reasoning system, that holds for all P, including those containing quasi-indexicals. In so doing, we explore the difference between reasoning in a public communication language and in a knowledge-representation language, we demonstrate the importance of representing proper names explicitly, and we provide support for the necessity of considering sentences in the context of extended discourse (e.g., written narrative) in order to fully capture certain features of their semantics.

Christians and Muslims in Nineteenth-Century China: Perspectives of Two Contemporary Journals

ABSTRACT

Throughout the nineteenth and early twentieth centuries, two journals stand out as primary sources of information about China. The Chinese Repository and The Chinese Recorder and Missionary Journal were edited by senior missionary scholars, who recorded observations of Chinese life and the development of the Church in China. While they make only scattered references to the Muslim population in China, these items are nevertheless significant indicators of the size, importance and nature of these Muslim communities. They also portray Christian attitudes to ‘Mohammedans’ and on occasions indicate Christian strategies of engagement with them. There was a particular burst of interest in ‘Mohammedism’ in the 1880s. However, engagement with the Muslim communities was never a priority for the Christian missionary force, as they were a distinct minority of the total Chinese population.     

The role of aggression‐related early maladaptive schemas and schema modes in aggression in a prisoner sample

Contemporary social‐cognitive aggression theory and extant empirical research highlights the relationship between certain Early Maladaptive Schemas (EMSs) and aggression in offenders. To date, the related construct of schema modes, which presents a comprehensive and integrated schema unit, has received scant empirical attention. Furthermore, EMSs and schema modes have yet to be examined concurrently with respect to aggressive behavior. This study examined associations between EMSs, schema modes, and aggression in an offender sample. Two hundred and eight adult male prisoners completed self‐report psychological tests measuring their histories of aggression, EMSs, and schema modes. Regression analyses revealed that EMSs were significantly associated with aggression but did not account for a unique portion of variance once the effects of schema modes were taken into account. Three schema modes, Enraged Child, Impulsive Child, and Bully and Attack, significantly predicted aggression. These findings support the proposition that schema modes characterized by escalating states of anger, rage, and impulsivity characterize aggressive offenders. In this regard, we call attention to the need to include schema modes in contemporary social‐cognitive aggression theories, and suggest that systematic assessment and treatment of schema modes has the potential to enhance outcomes with violent offenders.

     

Decomposing the within-person and between-person sources of variation in physical activity-cognition associations for low-active older adults

Abstract

Objectives: To examine within-person and between-person sources of variation in the relationship between physical activity and cognition in older adults participating in a walking program. To explore whether demographic, health and fitness variables, and their interactions with activity, are significant predictors of cognition.

Design: Brief longitudinal burst design.

Participants: 118 participants (91 females, mean age?=?72.81?+ 5.24 years).

Main Outcome Measures: Cognition, self-reported moderate-to-vigorous walking and self-reported moderate-to-vigorous physical activity were assessed at baseline and 6, 9, 12 and 16 weeks follow-up. Attendance at weekly walks was also recorded.

Results: Within-persons, changes in physical activity were related to select measures of executive functioning, with increased activity predictive of better cognition (three of four cognitive functions, p<.05). Between-persons, activity was also associated with cognition (two of four cognitive functions, p<.05). Younger age and higher education were related to better cognition. Interactions of demographic, health, and fitness variables with changes in within-person activity were generally non-significant.

Conclusion: The results highlight the importance of distinguishing within- from between-person effects in longitudinal analyses of the association between physical activity and cognition. This stringent within-person test of association underscores the potential value of simple physical activity interventions for improving cognitive function.     

Increasing calcium intake in young women through gain-framed,targeted messages: A randomised controlled trial

Background: Adequate calcium consumption during early adulthood can help prevent osteoporosis in women.

Purpose: The effects of gain-framed, targeted messaging on calcium intake were examined over 12 months.

Methods: Young women (18–19 years) not consuming sufficient calcium were randomly assigned to receive standard care materials (control) or gain-framed, targeted materials (experimental). Health belief model (HBM) constructs, calcium intake and markers of bone formation, resorption and bone mineral density were assessed at various time points throughout the year.

Results: Calcium intake increased significantly more in the experimental versus the control condition (p?<?0.01). Self-efficacy was the only HBM construct to improve significantly more in the experimental condition versus control (p?=?0.05). The HBM did not mediate changes in calcium intake. Measures of bone health did not differ between conditions by the end of this nonpharmacological intervention (p's?>?0.05).

Conclusions: It is possible to increase young women's calcium consumption through gain-framed, targeted messages.
