The impact of information about the prevalence of AIDS-Preventive behavior among men and women: The mediating role of social norms

Abstract

The present study was designed to examine the effect of information about the high prevalence of safe sex on condom use intention, and to investigate the possible mediating role of the perceived social norm of friends, and the perceived social norm of future. sexual partners. Participants were provided with gender specific prevalence information, that is with the information that most men have exclusively safe sex, or with the information that most women exclusively engage in safe sexual behavior. The results show some gender differences. Information about the high prevalence of safe sex among men tends to increase women's condom use intention, and this effect seems to be mediated by the paceived social norm of future sexual partners. Men's intention, on the other hand, seems to be unaffected by high prevalence information of safe sex. Implications for research and prevention are discussed     

Teoría multifactorial-sistemática—exposición sucinta—

RESUMEN

Los autores esbozan su Teoría Multifactorial Sistemática, que presenta una concepción general de la estructura, dinámica y desarrollo de las diferencias individuales en la personalidad integradora. Se analiza la estructura y dinámica de la individualidad desde el marco conceptual del procesamiento de la información, en el cual la personalidad -o el sistema psicológico total- viene a ser concebida como un compuesto jerárquico organizado de seis sistemas en interacción: sensorial, motor, cognitivo, afectivo, estilos y valores. Para ello comienzan con algunos comentarios acerca del modelo factorial y el de sistemas, describiendo seguidamente su concepción actual de “estructura”, “dinámicas” y “desarrollo” de la individualidad. A continuación se ocupan del significado de la interacción herencia-ambiente y persona-situación, y finalizan discutiendo problemas empíricos y teóricos no resueltos y las implicaciones de su teoría.     

The instructional information processing account of digital computation

What is nontrivial digital computation? It is the processing of discrete data through discrete state transitions in accordance with finite instructional information. The motivation for our account is that many previous attempts to answer this question are inadequate, and also that this account accords with the common intuition that digital computation is a type of information processing. We use the notion of reachability in a graph to defend this characterization in memory-based systems and underscore the importance of instructional information for digital computation. We argue that our account evaluates positively against adequacy criteria for accounts of computation.     

The Effects of Estradiol on Avoidance Learning in Ovariectomized Adult Rats

The present study examined the effects of ovariectomy and subsequent estradiol replacement on learning in young adult rats using a set of instrumental avoidance paradigms differing in the nature and extent of prior experience in the learning context. Thus, one group of animals was placed directly into avoidance learning (AV). A second group was trained on an appetitive task first, and then transferred into the aversive context (AP-AV). The third group was exposed to the training context without any specific appetitive response requirement, and then required to learn an active avoidance response (Context-AV). We found that estradiol (OVX+E) impaired avoidance acquisition in all cases relative ovariectomized controls (OVX). In contrast, while avoidance learning is improved following appetitive training or context exposure in both OVX+E and OVX animals, the OVX+E animals profit to a greater extent from the appetitive or context experience than do the OVX controls. We suggest that this difference may be due to enhanced attentional processes or improved hippocampal processing of contextual factors. Thus, estradiol negatively influences simple associative avoidance learning in ovariectomized rats, but appears to promote positive transfer.     

Methodological concerns in the psychology of religion: Continuities, losses and transforming perspectives

This article seeks solutions to what has recently been called the ‘crisis’ in the psychology of religion by returning to the programs of its founding fathers. It explores some of the methodological debates that followed the translation of William James' The Varieties of Religious Experience into German. More was at stake than the commonly drawn distinction between empirical and hermeneutical approaches to religion, or between quantitative and qualitative methods. What was at stake was the need for another kind of psychology in general. This article pays special attention to Wilhelm Wundt's fundamental criticism of James and of others in the psychology of religion. Despite the problems inherent in both James' and Wundt's aborted general psychology programs, each nonetheless contains approaches that may yet serve as an impetus to contemporary research on religion. Contemporary developments in cultural psychology in particular complement current research in the psychology of religion.     

Gender differences in leg stiffness and stiffness recruitment strategy during two-legged hopping

The authors compared leg stiffness (K(VERT)), muscle activation, and joint movement patterns between 11 men and 10 women during hopping. Physically active and healthy men and women performed continuous 2-legged hopping at their preferred rate and at 3.0 Hz. Compared with men, women demonstrated decreased K(VERT); however, after the authors normalized for body mass, gender differences in K(VERT) were eliminated. In comparison with men, women also demonstrated increased quadriceps and soleus activity, as well as greater quadriceps-to-hamstrings coactivation ratios. There were no significant gender differences for joint movement patterns (p>.05). The relationship between the observed gender differences in muscle recruitment and the increased risk of anterior cruciate ligament injury in women requires further study.     

Readiness for Change: Involving the Family with Adolescents in Residential Settings

Adolescence is a pivotal time in human development and can be a challenging time for individuals to learn to regulate emotions, while also balancing biopsychosocial changes. The family plays a key role in an adolescent’s development. Thus, it is imperative for families to remain involved when adolescents are in residential treatment for emotional or behavioral issues. In this paper, we explore the benefits of, and methods for, increasing the identified patient’s (i.e., the adolescent’s) and the family’s readiness for change. The process of increasing family engagement in residential treatment is considered through the lens of the Stages of Change model. Barriers practitioners may face with adolescents and their families are also addressed.     

Modeling Individual Differences in Autobiographical Memory Distributions Using Mixed Logitnormal Regression

We introduce a model for examining individual differences in the lifespan distribution of autobiographical memories (after the exclusion of recent memories). The model is based on the logitnormal distribution, contains two submodels, one for location (average age at which autobiographical memories were encoded) and one for scale (range of ages at which autobiographical memories were encoded), allows for the inclusion of predictor variables, and includes random effects. The model was used to analyze autobiographical memories reported by 90 older participants. Results show that there were reliable individual differences in location and scale. Moreover, age, proportion of positive memories, proportion of first‐time experiences, comprehensibility, and meaningfulness accounted for 26% of individual differences in location and 23% of individual differences in scale of autobiographical memory distributions. These findings indicate that individual differences are present in autobiographical memory distributions and can, in part, be accounted for by characteristics of the memories and of the person who generated them.Copyright © 2016 John Wiley & Sons, Ltd.
