Women coping with AIDS in Africa: contributions of a contextually grounded research methodology

The primary objective of this report is to describe a contextually grounded approach to the investigation of coping and psychological functioning in AIDS-sick mothers. Five AIDS-sick women on antiretroviral therapy who had at least one child under 6 years of age living in their households were interviewed. Among the issues that emerged was the complexity of the women's psychological functioning, the fact that they made strategic decisions about disclosure aimed at protecting important social support networks, and that their well-being was dynamically influenced by factors in the home and community. The study provides evidence for the value of a contextual approach when investigating the psychological functioning of HIV positive mothers living in poor high-HIV prevalence communities in developing countries.     

Effects of LMX and differential treatment on work unit commitment

The Leader-Member exchange (LMX) theory of leadership states that leaders do behave differently towards the various members in their work unit. Relatively little attention has been devoted to the question of whether members' perceptions of differential treatment on the part of the leader affects their commitment to the work unit. Perceptions of the amount of differential treatment within their work unit did not explain additional variance in members' work unit commitment after the effects of LMX quality were accounted for. There was, however, a significant interaction effect of LMX quality and differential treatment on work unit commitment. The perception of a large number of differential treatment incidents seems to act as a neutralizer with respect to the positive effects LMX quality may have.     

Can false memories be created through nonconscious processes?

Presentation times of study words presented in the Deese/Roediger and McDermott (DRM) paradigm varied from 20 to 2000 ms per word in an attempt to replicate the false memory effect following extremely short presentations reported by. Both in a within-subjects design (Experiment 1) and in a between-subjects design (Experiment 2) subjects showed memory for studied words as well as a false memory effect for related critical lures in the 2000-ms condition. However, in the conditions with shorter presentation times (20 ms in Experiment 1; 20 and 40 ms in Experiment 2) no memory for studied words, nor a false memory effect was found. We argue that there is at present no strong evidence supporting the claim for a nonconscious basis of the false memory effect.     

How Accurate Are National Stereotypes? A Test of Different Methodological Approaches

We compared different methodological approaches in research on the accuracy of national stereotypes that use aggregated mean scores of real people's personality traits as criteria for stereotype accuracy. Our sample comprised 16,713 participants from the Central Europe and 1,090 participants from the Baltic Sea region. Participants rated national stereotypes of their own country using the National Character Survey (NCS) and their personality traits using either the Revised NEO Personality Inventory or the NCS. We examined the effects of different (i) methods for rating of real people (Revised NEO Personality Inventory vs. NCS) and national stereotypes (NCS); (ii) norms for converting raw scores into T‐scores (Russian vs. international norms); and (iii) correlation techniques (intraclass correlations vs. Pearson correlations vs. rank‐order correlations) on the resulting agreement between the ratings of national stereotypes and real people. We showed that the accuracy of national stereotypes depended on the employed methodology. The accuracy was the highest when ratings of real people and national stereotypes were made using the same method and when rank order correlations were used to estimate the agreement between national stereotypes and personality profiles of real people. We propose a new statistical procedure for determining national stereotype accuracy that overcomes limitations of past studies. We provide methodological recommendations applicable to a wider range of cross national stereotype accuracy studies. Copyright © 2018 European Association of Personality Psychology     

儿童早期字词意识的发展

探讨了4～6岁儿童早期字词意识的年龄差异,拟为元语言意识的多因素模型提出支持性的证据。实验结果表明:4岁儿童的字词意识及5岁儿童的词意识还很不清晰,6岁儿童已达到较高的字意识水平;幼儿在字意识任务上的成绩显著地优于词意识任务。
