Protective role of educational level on episodic memory aging: An event-related potential study

The aim of the present experiment was to investigate whether educational level could modulate the effect of aging on episodic memory and on the electrophysiological correlates of retrieval success. Participants were divided into four groups based on age (young vs. older) and educational level (high vs. low), with 14 participants in each group. Event-related potentials (ERP) were recorded while participants performed a word-stem cued-recall task. Age-related memory deficits were greater for the less educated individuals. Age differences in the ERP old/new effects were also modulated by the level of education. This study demonstrated that the effects of age on episodic memory and ERP correlates of retrieval success are smaller in participants with high educational levels than those with lower levels. These findings provide support for the reserve hypothesis and highlight the need to consider individual differences when studying cognitive and cerebral changes in aging.     

Influencia del placebo en el tratamiento de la cefalea

Resumen

El objetivo de este trabajo es estudiar la acción del efecto placebo en el tratamiento de la cefalea mediante biofeedback EMG. Un total de 22 pacientes de cefalea fueron asignados a tres condiciones experimentales: a) biofeedback EMG placebo con control interno; b) biofeedback EMG placebo con control externo; y c) biofeedback EMG real. Los resultados señalan que el biofeedback EMG placebo es tan eficaz como el real para reducir la frecuencia de la cefalea. Se discuten, por último, las distintas variables medidas en el estudio para determinar la naturaleza y eficacia del efecto placebo.     

Mobile Cultures of Migrant Workers in Southern China: Informal Literacies in the Negotiation of (New) Social Relations of the New Working Women

In this paper, we analyze the data collected through in-depth interviews of migrant workers in Southern China about their mobile cultures. In particular, we focus on understanding the role that mobile cultures play in female workers’ negotiation of their social and romantic relations and leisure space and how these negotiations are directly or indirectly facilitated by development of informal literacies through their frequent short message service communicative practices. These will help us understand the lifestyle aspirations and life trajectories of the new young working women in China who are experiencing the most rapid socioeconomic changes in society and negotiating their ways of life amidst much tension between old and new values governing lifestyle aspirations, familial, and gender relations.

The mapping of Spanish social psychology through its conferences: a bibliometric perspective

This study of papers gathered from the proceedings presented at Spanish social psychology conferences explores the use of bibliometrics for studying scientific disciplines. A reference database of all the papers included in the conference proceedings of events held from 1983 to 2000 was generated and classified by thematic area, paper type and author institutional affiliation. The references were laid out on contingency tables and mapped with correspondence analysis. The results show that there is a growing number of co-authored papers and a predominance of empirical over theoretical paper types. Some institutions have a higher concentration of theoretical papers while others work mostly in the areas of organizational and health psychology. In terms of empirical papers, there is a tendency towards generating more qualitative-based studies over the span of time captured by this work. There are also a number of papers written about such areas as cultural psychology that points to the emergence of an interest in critical social psychology. Concluding remarks underline the role of conferences and scientific meetings as an important indicator of the dynamic development of a scientific discipline.     

Personality Dispositions and Health-related Habits and Attitudes: a Cross-sectional Study

We examined the relations between the Big-Five personality dimensions, Health Locus of Control, and health-related behaviours and attitudes. We focused on the question of potential advantages of the five-factor model as an integrated framework for personality and health research. Fifteen health habits and attitudes (including smoking, alcohol consumption, exercise, a variety of dietary practices, current stressors, and attitudes toward smoking and alcohol consumption) were used to operationalize the subjects’ lifestyle. The study involved 1184 students from twelve different university schools. Although our results resembled those of other studies, we found that Conscientiousness and Agreeableness were particularly noteworthy as predictors of health behaviours and cognitive attitudes and tendencies. Our results also suggest that both factors should be included as explanatory constructs in personality–disease models that may indirectly affect disease proneness via unhealthy behaviours. © 1997 John Wiley & Sons, Ltd.     

Bibliometric Review of the Repertory Grid Technique: 1998–2007

This bibliometric review covers the scientific production with or about the repertory grid technique (RGT; Kelly, 1955/1991) between 1998 and 2007. An analysis of previous reviews suggests the need for a more careful and broad process of bibliographic research. With this aim, 24 bibliographic sources were used to cover a wide range of specialties. We began by drawing up an explicit protocol in which the research terms were detailed. Then we consulted the bibliographic sources, taking into account a specification of inclusion and exclusion criteria. As a result of this process, 973 references were obtained: 468 journal papers, 335 book chapters, 108 doctoral theses, and 62 books. The review also evaluates the types of documents found, the evolution of the number of works published, the repertory grid's fields of application, and the degree of openness to other disciplines. The most relevant authors, their affiliations, countries, and the publication language are also revealed in this article, as well as the major journals contributing to dissemination of the work done with this technique.     

A new approach for differential item functioning detection using Mantel-Haenszel methods. The GMHDIF program

To date, the statistical software designed for assessing differential item functioning (DIF) with Mantel-Haenszel procedures has employed the following statistics: the Mantel-Haenszel chi-square statistic, the generalized Mantel-Haenszel test and the Mantel test. These statistics permit detecting DIF in dichotomous and polytomous items, although they limit the analysis to two groups. On the contrary, this article describes a new approach (and the related software) that, using the generalized Mantel-Haenszel statistic proposed by Landis, Heyman, and Koch (1978), permits DIF assessment in multiple groups, both for dichotomous and polytomous items. The program is free of charge and is available in the following languages: Spanish, English and Portuguese.     

Universal Self Consciousness mysticism and the physical completeness principle

Philosophers promoting a version ofUniversal Self Consciousness mysticism(including Wainwright, Alston, Hick, Wilber andForman) take it that their interpretations ofmysticism are consistent with currentscientific findings. However, their theorieshave been implicitly or explicitly against thecentral claim arising from science, namely, thephysical causal completeness principle. Thereis strong ground to accept physical causalcompleteness for human functioning, and theassessment of physical completeness isindependent of the phenomenology of UniversalSelf Consciousness mystical experience.Further, there is a positive account ofUniversal Self Consciousness mysticism thataccepts physical causal completeness. Such anaccount is preferable to the many accounts thatboth require its denial and yet give nobasically satisfactory evidence to ground thatdenial.     

Racial Stereotypes and Gender in Context: African Americans at Predominantly Black and Predominantly White Colleges

In this study, relationships among stereotype expectations, gender, and academic self-concept and performance of African American students in predominantly White and predominantly Black college contexts were examined. Stereotype expectations are students' perceptions of biased treatment and evaluation within their major classroom settings (SE). Findings indicated that students' majors were related to stereotype expectations, as well as to their academic competence. Our results also provide evidence of gender and institutional interactions in the relationships between stereotype expectations and academic outcomes. Results are discussed in terms of the need to examine issues of race and gender in the academic experiences of African Americans, as well as how their specific school and classroom contexts may influence their experiences.
