Gender-Linked Differences in Everyday Memory Performance: Effort Makes the Difference

Previous research has found gender differences in everyday memory tasks such as remembering shopping lists or directions, and these findings can be attributed to increased motivation or memory skill resulting from the association of different tasks with masculine or feminine gender roles. To investigate the motivational explanation, the recall of an ambiguous shopping list, labeled as grocery or hardware, was examined under instructions that stated that either women or men are good at the task, or instructions that were neutral. The findings were not consistent with the skill explanation. There was a significant interaction between list label, participant gender, and instructions, which can be explained in terms of the increased or decreased motivation that might arise from particular combinations of label and instruction.     

Efficacy of constant time delay implemented by peer tutors in general education classrooms

We evaluated the effects of teaching 13 typically developing children to use constant time delay when tutoring three of their peers who had substantial disabilities. We measured the extent to which the tutors used the constant time delay procedure correctly and the tutees' correct performance on the skills being taught. A multiple probe design across behaviors was used. The results indicated that (a) the tutors used each step of the constant time delay with a high degree of procedural fidelity; (b) the students with disabilities acquired the skills that were taught during peer tutoring; and (c) modifications of the procedure were required for 2 of the 3 students with disabilities, and the peers tutors were able to implement the modifications. Implications for practice and future research are described.     

Effectiveness of a brief group RET treatment for divorce-related dysphoria

This study evaluated the effectiveness of a brief, group rational-emotive (RET) treatment and problem solving treatment for divorce related dysphoria, involving six hours of therapy over 22 days. A waiting list condition was used for comparison. On three measures of dysphoria, RET and Problem-Solving subjects improved significantly more than Waiting List subjects and RET and Problem-Solving subjects maintained their improvement at a one-month follow-up. There was no significant difference in improvement between RET and Problem-Solving treatments. Effectiveness of the treatments could have been due either to specific content, group therapy components, or nonspecific effects.John Malouff is a clinical psychologist with the Rehabilitation Center of Palm Beach, Florida.

Investigating the relationship between product involvement and consumer decision‐making styles

• Recently, a number of studies have investigated consumer decision‐making styles (CDMS) and their importance to consumer behaviour research. However, research designs suggested to date are mainly replications of a study by Sproles and Kendall ( 1986 ) proposing eight mental characteristics, the so‐called Consumer Styles Inventory (CSI). The CSI has been applied across cultures, but without critically examining its validity and reliability. A major concern is the postulated product independence of CSI. The aim of this study is to further develop this approach, to apply it to different product categories and to investigate the relationship between product involvement and CDMS. In doing so, we conducted a survey in Great Britain and Germany, and analysed the data using exploratory and confirmatory factor analysis. Not only did we demonstrate that there is a relationship between products and CDMS, but also that CDMS are governed by consumers' perceived product involvement. Important implications for marketing practice can be derived.

Effects of processing bias on the recognition of composite face halves

Research has shown that face recognition accuracy can be improved by prior global processing and impaired by prior local processing (Macrae & Lewis, 2002). The aim of this study was to test the processing bias account of face recognition, using the composite face task (Young, Hellawell, & Hay, 1987), a test of featural recognition. Undergraduate volunteers (N=75) participated in a between-subjects design that tested their ability to recognize face halves within a composite, following either global or local Navon processing or a control task. Results showed that, as compared with the control task, local processing speeded ability to recognize face halves. These results provide support for the processing bias account of face recognition.     

Endocrinology of menopausal transition and its brain implications

The central nervous system is one of the main target tissues for sex steroid hormones, which act on both through genomic mechanisms, modulating synthesis, release, and metabolism of many neuropeptides and neurotransmitters, and through non-genomic mechanisms, influencing electrical excitability, synaptic function, morphological features, and neuron-glia interactions. During the climacteric period, sex steroid deficiency causes many neuroendocrine changes. At the hypothalamic level, estrogen withdrawal gives rise to vasomotor symptoms, to eating behavior disorders, and altered blood pressure control. On the other hand, at the limbic level, the changes in serotoninergic, noradrenergic, and opioidergic tones contribute to the modifications in mood, behavior, and nociception. Hormone replacement therapy (HRT) positively affects climateric depression throughout a direct effect on neural activity and on the modulation of adrenergic and serotoninergic tones and may modulate the decrease in cognitive efficiency observed in climaterium. The identification of the brain as a de novo source of neurosteroids, suggests that the modifications in mood and cognitive performances occurring in postmenopausal women may also be related to a change in the levels of neurosteroids. These findings open new perspectives in the study of the effects of sex steroids on the central nervous system and on the possible use of alternative and/or auxiliary HRT.     

PEER MODELING OF RESPONSE CHAINS: OBSERVATIONAL LEARNING BY STUDENTS WITH DISABILITIES

Peer models (classmates without disabilities) who were proficient in performing a task completed one response chain each day and described the steps they performed while their classmates with disabilities observed. Three students with disabilities participated, and their performance of the response chains was assessed immediately prior to and following the peer modeling each day. A multiple probe design across response chains, replicated across children with disabilities, was used. In addition, participation and social interactions of children with disabilities and their peer models were assessed in classroom activities after daily modeling sessions. The results indicate that the peer models performed the response chains accurately and quickly, and students with disabilities acquired the response chains. Across the study, participation in classroom activities was high, social interactions were low, and neither was affected by the peer modeling intervention.     

CULTURE AND COGNITIVE PROBLEMS

Culture et problèms cognitifs. — L'A. étudie les effets du niveau culturel et des processus d'acculturation sur deux aspects du fonctionnement cognitif: L'exploration d'une configuration perceptive et L'élaboration des informations. Pour rendre compte du premier, ont été retenus les résultats d'une recherche faite sur des populations primitives de L'Amazonie soumises au test de Roschach: L'augmentation du pourcentage des réponses Dd., chez les sujets “acculturés” par rapport à ceux qui ne le sont pas, indique qu'il y a passage d'une phase de réponses globales et stéréotypées à une phase d'analyse détaillée bien qu'encore primitive. En second lieu, L'élaboration des informations drées de L'exploration d'une configuration perceptive a été étudiée relativement aux points suivants: causalité physique, notions de conservation, intégration de variables antagonistes et opération de combinaison. Les résultats montrent qu'un milieu socio-culturel sous-développé ou un niveau d'instruction nul ou insuffisant, ou encore un milieu de travail peu “acculturé” peuvent faire obstacle au développement d'un processus de pensée apte á considérer plusieurs variables, même antagonistes, à la fois, et à les intégrer dans une fonction unique, par un réseau de relations multiplicatives. En général, la seule maturation biologique ne permet pas d'atteindre complètement ce type de pensée. Le raisonnement des sujets adultes qui viennent d'un milieu sous-développé fluctue entre schème notionnel et schème figuratif; il se rapproche de L'un ou de L'autre selon le degré de pression qu'exercent les éléments perceptifs. C'est pourquoi on évoque ici L'utilité, limitée a la résolution d'un problème, que pourrait avoir le fait de dormer aux sujets des instruments mécaniques de “servo-pensée”. Les résultats de ces études semblent enfin montrer que certains retards dans le développement intellectuel peuvent être rattrapés lorsqu'on place les sujets dans un milieu plus favorable.
