Estimating retest effects in longitudinal assessments of cognitive functioning in adults between 18 and 60 years of age

Several analyses were conducted on data from samples of adults between 18 and 58 years of age who completed the same cognitive tests after an interval ranging from less than 1 week to 35 years. Because the retest interval varied across individuals, it was possible to determine the length of time needed before the gains associated with a retest decreased to 0 and to obtain simultaneous estimates of the magnitude of effects associated with increased age and a prior assessment. The results indicated that for adults within this age range, 7 or more years were needed before positive retest effects were no longer detectable. Age effects in longitudinal comparisons could be interpreted in terms of large positive effects associated with a prior assessment and negative effects associated with age that were comparable in magnitude to those observed in cross-sectional comparisons.     

A brief scale to assess cognitive impairment in psychiatric patients

The Screen for Cognitive Impairment in Psychiatry(SCIP) is a brief instrument designed to assess cognitive deterioration in patients with psychiatric disorders, for example, schizophrenia. This study presents the first results obtained with the Spanish version of the SCIP in its three parallel forms with a sample of university students, these results being compared with those obtained with the English version. It is concluded that although there are no form effects, and that therefore the different forms can be used without distinction, there are certain practice effects on some of the instrument's sub-scales. There is also a language effect that may be due to sample and/or cultural characteristics. Finally, in both versions intra-class correlation coefficients and factorial structure are very similar.     

Activity-based anorexia: ambient temperature has been a neglected factor

Activity-based anorexia refers to the self-starvation of rats exposed to experimental conditions that combine restricted access to food with access to an activity wheel. This paper compares previous studies of this phenomenon in relation to the ambient temperatures (AT) that were employed. On this basis, and from some more direct evidence, we argue that AT is an important, but neglected, factor in activity-based anorexia research. More attention to AT is needed in future research, since its neglect threatens the validity of conclusions drawn from those studies. Furthermore, direct examination of the effect of AT on activity-based anorexia will allow a better understanding of the mechanisms underlying this phenomenon and the possible clinical implications for the treatment of human anorexia nervosa.     

The response-cued completion hypothesis and the nature of residual cost in regular switch

Three experiments are presented that compare the residual cost found when shifting from one task to another under different extra-response conditions, to test whether the response is the main factor to complete mental set reconfiguration. We investigated whether residual costs can be eliminated if participants carry out a response prior to completing switch trials. In all experiments, participants were required to press an extra key during the inter-trial interval (ITI) to proceed. In experiment 1, this extra response consisted of pressing the space bar. In experiment 2, the response consisted of pressing one of the two possible keys that belonged to the alternating tasks response set. In experiment 3, the interpolated response involved pressing one of the two possible keys, not belonging to the response set of the alternating tasks. We found no residual cost in the second or the third experiments. To explain the nature of residual cost we discuss the data in the context of a response cued completion hypothesis.     

I love you too much to keep social distance: Closeness in relationships and (dis)engagement in preventive behaviors during the COVID-19 pandemic

Although we are witnessing a new phase in the management of COVID-19, understanding what predicts adherence to preventive behaviors still remains crucial. In this study we focus on interpersonal relationships by specifically investigating whether engagement in preventive behaviors when in the presence of others may be a function of the type of relationship (in terms of closeness) one has with others. Because close others are often perceived similar to the self compared to strangers, we put forward that close relationships may inadvertently decrease COVID-19 risk perceptions which may ultimately decrease compliance with recommended behaviors when in their presence. To test this hypothesis, 747 Italian respondents were invited to answer one out of four versions of a questionnaire differing on the target (i.e., friends vs. parents vs. grandparents vs. strangers), including questions regarding COVID-19 risk perceptions and intentions to engage in preventive behaviors. Mediation analysis showed that close relationships (i.e., with friends, parents, and grandparents) compared to nonclose relationships (i.e., with strangers) predicted lower intentions to engage in preventive behaviors via lower risk perceptions. Altogether, these results shed light on the role played by closeness in indirectly shaping individuals' dis(engagement) in preventive behaviors and contribute to better understand possible unconscious biases which may undermine our safety during the COVID-19 pandemic.     

Statements

The churches today are called to confess anew their faith, and to repent for the times when Christians have remained silent in the face of injustice or threats to peace. The biblical vision of peace with justice for all, of wholeness, of unity for all God's people is not one of several options for the followers of Christ. It is an imperative in our time.

Individual Behavior Consistencies as Interactive Styles: Their Relation to Personality

Two experimental studies were carried out in order to find within-subject consistencies as individual differences in a concurrent choice situation simulating risk-taking. In a first experiment, six adults were exposed to different values of probability and numbers of reinforcement in a task involving betting on two simultaneous horse races displayed on a microcomputer monitor. In the second experiment, two subjects were exposed to a within-session replication of the first experiment. The results in both experiments support the reliability of within-subject consistencies when experimental tasks are built as open contingencies. The conceptual and experimental implications of the data are discussed in relation to the study of personality.

     

Exploratory Approaches for Studying Social Interactions,Dynamics, and Multivariate Processes in Psychological Science

In this article, I argue for the need of more use of exploratory techniques to identify dynamics in social interactions. I describe several approaches as they are applied to multivariate time series data. The first approach is an algorithm that searches for periods of variability and stability at the individual level as well as for patterns of overlap in such periods between the two individuals in a couple. These patterns describe the daily ups and downs in the couples' affect and are predictive of the state of the couples 1 to 2 years later. The second approach, hierarchical segmentation, is based on the idea of partitioning the time series in segments with distinct data patterns. In the case of data from dyads, as in the illustration, the patterns can be compared in terms of coherence between the 2 individuals in the dyad. The third approach is based on network analysis, and its use is shown as a method to examine data transitions at the individual and dyadic level as well as system-wide coherence in multivariate systems. For each approach, I provide examples of its use with empirical data. The article ends with general guidelines and recommendations for researchers interested in using exploratory methods as a way to examine psychological processes.     

Improving academic attitudes among ethnic minority youth at risk for early school leaving: the interactive effects of cross‐group friendships and ethnic identity

A growing body of research suggests that positive interethnic experiences enhance academic attitudes among ethnic minority youth. A number of studies also show that minority youth with an achieved ethnic identity have better academic attitudes and performance. Integrating these literatures, we aim to verify the combined effects of cross‐group friendships and ethnic identity on academic attitudes among a sample of youth at risk for early school leaving. The results showed that cross‐group friendships had a positive impact on academic attitudes for minority youth, but not for majority youth. However, individual levels of ethnic identity moderated these effects, which held true for minority youth with higher levels of ethnic identity. The theoretical and practical implications of these findings are discussed.     

The scandal of ecstasy: communication, Sufi rites, and social reform in 1930s Morocco

Modern Islamic reformists in Morocco condemned ecstatic Sufi trance rites as heterodox spectacles. But if the heterodoxy of these rites remains self-evident, the still common reformist critique of spectacle begs historical explanation. This article proposes that a main theme of post-1930 nationalist reformism in Morocco was communication and its containment. In this period, new reformists – “Young Moroccans” and “New Salafis” – fixated upon the power of ecstatic rites to connect and coalesce the urban underclasses and to elicit recognition from the colonial state and an emergent global audience. Just as new reformists sought to use technologies of mass communication, including the newspaper and camera, to speak to and for “the People,” they chafed at the global renown these same media lent to public Sufi spectacles. Examining Moroccan print media in 1930s Fez, I show that anti-Sufi critiques were primarily neither doctrinal nor anti-colonial; new reformists aimed, rather, to domesticate the popular connective force of ritual as well as the enhanced power of these picturesque rites to speak for the nation.
