Short-term and long-term memory deficit following intracarotid Amytal injection: Further support for the memory consolidation hypothesis

To test the three main hypotheses of the human amnesic syndrome (encoding, consolidation, retrieval), we designed an original protocol for memory assessment under Amytal that included, in addition to a retrograde memory measure, both short-term and long-term anterograde memory measures. Twenty epileptic patients with SEEG-confirmed unilateral temporal lobe foci were given right and left injections on successive days. Only the long-term memory measure for material presented under Amytal was significantly related to the presence of a temporal contralateral epileptogenic focus, even if it was assessed when the hemisphere had completely recovered from the effect of Amytal. Short-term memory deficits were observed equally often after injections ipsilateral and contralateral to the epileptogenic focus, and no retrograde amnesia was observed. These results are consistent with the consolidation hypothesis.     

Linking personal values to gender

Two studies were conducted to investigate the relation between personal values and aspects of gender. Study 1 used the Rokeach Value Survey (RVS) to examine the nature of stereotypes concerning the values of the “typical man” and the “typical woman”. Results supported the hypothesis that men are viewed as more likely to endorse agentic values, such as freedom and accomplishment, whereas women are viewed as more likely to endorse communal values, such as friendship and equality. Study 2 assessed men and women's possession of stereotypic sets of masculine and feminine values, using the RVS, and examined their relation to gender-related personality traits, gender-related interests and role behaviors, and global self-perceptions of masculinity and femininity. Masculine values were found to be significantly related to socially desirable masculine traits, socially undesirable masculine traits, masculine interests and a global self-concept of masculinity. Feminine values were shown to be significantly related to socially desirable feminine traits, feminine interests, feminine role behaviors, and a global self-concept of femininity. These results suggest that gender-linked personal values merit inclusion with traits, interests, role behaviors, and global self-concepts as part of an emerging multidimensional conception of gender characteristics.     

The influence of social comparison with less fortunate others on task performance: The role of gender motivations or appropriate norms

French male and female children performed a cognitive-perceptual task while anticipating or not public comparisons of their score with probably less fortunate others at a time when concerns about fitting in to social expectations were maximized. As predicted, boys performed better and girls poorer when social comparison was anticipated than when it was not. This suggested that task performance can depend on the compatibility of the social context of cognition with gender motivations or appropriate norms.     

Desirable and undesirable gender traits in three behavioral domains

The present study investigated the factorial validity of a four-factor model of gender stereotypes in 888 subjects (97% Anglo-Australian Caucasian). The scale reflected the constructs desirable masculinity, desirable femininity, undesirable masculinity and undesirable femininity. LISREL analyses showed that this four-factor model fitted the data better than either a two-factor model consisting of overall masculinity and femininity or an one-factor bipolar model. Furthermore, the study highlights the utility of studying both desirable and undesirable gender traits as they generally predicted different behaviors for males and females.     

Social regulation and individual cognitive function: Effects of individuation on cognitive performance

Numerous experiments have illustrated the intervention of social regulations in individual cognitive functioning, applying such concepts as social co-ordination, socio-cognitive conflict and social marking. Two experiments, involving secondary school pupils are presented within this general framework. The first tests the hypothesis that individual cognitive functioning, highlighted in a task requiring mobilization of knowledge learned to that end, can under certain conditions be regulated by experimentally induced social resources. The second experiment uses the same paradigm to compare the information processing, under anonymous versus individuated conditions, of pupils respectively with successful and unsuccessful academic histories. The results of both experiments indicate that cognitive functioning is strongly influenced by the social situations created within the experimental settings. These results are discussed in terms of the social meta systems which may intervene in cognitive processes.     

Gender and education impact on brain aging: a general cognitive factor approach

In cognitive aging research, the study of a general cognitive factor has been shown to have a substantial explanatory power over the study of isolated tests. The authors aimed at differentiating the impact of gender and education on global cognitive change with age from their differential impact on 4 psychometric tests using a new latent process approach, which intermediates between a single-factor longitudinal model for sum scores and an item-response theory approach for longitudinal data. The analysis was conducted on a sample of 2,228 subjects from PAQUID, a population-based cohort of older adults followed for 13 years with repeated measures of cognition. Adjusted for vascular factors, the analysis confirmed that women performed better in tests involving verbal components, while men performed better in tests involving visuospatial skills. In addition, the model suggested that women had a slightly steeper global cognitive decline with oldest age than men, even after excluding incident dementia or death. Subjects with higher education exhibited a better mean score for the 4 tests, but this difference tended to attenuate with age for tests involving a speed component.     

Internet‐initiated sexual abuse: adolescent victims' reports about On‐ and Off‐line sexual activities

The purpose of the present study was to investigate how adolescent girls, who had been sexually (on‐ and off‐line) deceived and abused by an Internet hebephile, reported about these acts. As we had access to documentation of 68 girls' conversations (i.e. chat logs) and involvement with the perpetrator, we were able to gauge what the victims reported during the police interview against this detailed documentation. In contrast with findings from previous research, the majority of victims reported about the off‐line activities (real‐life meetings) with the perpetrator. However, the victims omitted and/or denied more of the on‐line activities, specifically the more severe sexual on‐line acts (sending nude photos and participating in sexual web shows). There is probably a gap between what the victims reported and what they presumably remembered about the on‐line activities. Factors that might have affected the victims' pattern of reports are discussed. Copyright © 2008 John Wiley & Sons, Ltd.
