Interactions between stereotype threat,subjective aging,and memory in older adults

This study examined whether the effects of stereotype threat on memory and subjective age were moderated by positive age stereotypes and self-perceptions of aging among older adults. Perceived threat as a mechanism underlying these effects was also explored. Results showed that stereotype threat (high vs. low threat) did not affect the dependent variables. Moreover, self-perceptions of aging did not moderate the effect of stereotype threat on the dependent variables. However, for people with more positive age stereotypes, older people under highthreat perceived more threat than people under low threat. This could be explained by an effect of age stereotypes in the high-threat group: the more positive age stereotypes held by participants, the more they perceived threat, which in turn decreased their memory performance and made them feel mentally older. We hypothesized that age group identity is stronger in people with more positive age stereotypes, which increase perceived threat.     

The inhibitory avoidance test optimized for discovery of cognitive enhancers

In the present article, we describe a new protocol for the inhibitory avoidance test, with a dual purpose: (1) to provide a leß variable and more reliable aßeßment of the efficacy of potential cognitive enhancers in antagonizing scopolamine-induced long-term-memory deficits, and (2) to secure a high throughput for pharmacological screening of cognitive enhancers. The new protocol consists of two acquisition trials that are followed 24 h later by a single retention trial. In the present study, this protocol clearly dißociated the frequency distributions of retention latencies between scopolamine- and vehicle-treated groups and allowed validation by means of two acetylcholinesterase inhibitors—tacrine and donepezil—that proved to be active in counteracting the scopolamine-induced memory deficit. This protocol also produced stability of the behavioral response to pharmacological agents over a 3-year period. A statistical power analysis indicated that, depending on the efficacy of the drug/dose, a sample size of 5–12 mice was required in order to show a reversal of the scopolamineinduced memory deficit. The double-trial acquisition protocol is suitable for testing cognitive enhancers, while also providing a clearly enhanced throughput.     

Insidious dangers of benevolent sexism: consequences for women's performance

Four experiments found benevolent sexism to be worse than hostile sexism for women's cognitive performance. Experiments 1-2 showed effects of paternalist benevolent sexism and ruled out explanations of perceived sexism, context pleasantness, and performance motivation. Experiment 3 showed effects of both paternalist and complementary gender differentiation components of benevolent sexism. Benevolent sexism per se (rather than the provision of unsolicited help involved in paternalism) worsened performance. Experiment 4 showed that impaired performance due to benevolent sexism was fully mediated by the mental intrusions women experienced about their sense of competence. Additionally, Experiment 4 showed that gender identification protected against hostile but not benevolent sexism. Despite the apparently positive and inoffensive tone of benevolent sexism, our research emphasizes its insidious dangers.     

Be Too Kind to a Woman, She’ll Feel Incompetent: Benevolent Sexism Shifts Self-construal and Autobiographical Memories Toward Incompetence

The present study investigated how benevolent (BS) and hostile sexism (HS) shift women’s self-construal and autobiographical memory. Belgian undergraduates (only women, N?=?45, mean age?=?21.8) were confronted either by BS, HS or neutral comments in the context of a job interview. After performing a cognitive task, participants reported the intrusive thoughts that came to their mind during the task. Later, autobiographical memory for self-incompetence was assessed. Performance response latencies were slower after BS than HS. Also, BS generated more disturbing mental intrusions related to the idea of being incompetent than HS. Autobiographical memory similarly indicated greater access for incompetence after BS. Although HS was more aggressive in tone, it did not shift women’s self-construal and autobiographical memories toward incompetence.     

Mood and positive testing in social interaction

Why, how and when does mood influence positive testing, that is, the selection of matching questions, when people actively search for information about others they meet? In four experiments, we demonstrated that happy mood increased positive testing compared to sad mood. Experiment 1 showed that happy participants were more strongly motivated to get along and smooth the interaction to come than sad ones. In addition, evidence was provided by a mediation analysis that happy mood increased the preference for positive testing because of such an improved motivation to get along. Furthermore, Experiment 2 showed that happy participants' preference for positive testing vanished when cognitive resources were limited. The preference for positive testing appeared under happy mood only when the context made salient the goal to get along (Experiments 3 and 4). Together, these results suggest that positive testing in a social‐hypothesis testing paradigm may have social values. Copyright © 2009 John Wiley & Sons, Ltd.

Asymmetrical international attitudes

In general, attitudes towards nations have a fair amount of reciprocity: nations either like each other, are relatively indifferent to each other, or dislike each other. Sometimes, however, international attitudes are asymmetrical. In this study, we use social identity theory in order to explain asymmetrical attitudes. Parting from social identity theory, asymmetrical attitudes can be predicted to occur most likely between countries that are linguistically either similar or closely related, but differ in size. Europe, more than any other continent, offers a rich variety of nations which represent natural conditions for our study, such as size and degree of linguistic similarity. In order to test hypotheses derived from social identity theory, we asked respondents (N = 405) from (Dutch‐ and French‐speaking) Belgium, France, Germany, and The Netherlands to fill out a questionnaire on three large nations (Germany, Great Britain, France) and three smaller ones (The Netherlands, Belgium, and Denmark). Results strongly supported hypotheses and confirm that a social identity approach may help to better understand international attitudes. Copyright © 2002 John Wiley & Sons, Ltd.     

Stereotype content of people with acquired brain injury: Warm but incompetent

Since stereotypes about people with acquired brain injury (ABI) can lead to prejudice, studying these stereotypes is highly important. In two studies, we examined these stereotypes both on idiosyncratic dimensions and on the two dimensions of the Stereotype Content Model. Participants completed a specific questionnaire about ABI and warmth and competence questionnaires regarding people with ABI and other social groups. Specific stereotypes about ABI were found to be underpinned by dimensions of “cognitive impairments and ADL limitations,” “catastrophic outcomes,” and “personal and interpersonal development.” Within the model, people with ABI were seen as being warm but incompetent. The ambivalent ABI stereotype could elicit prejudicial attitudes that may impede rehabilitation.
