Individual differences in Sternberg’s memory scanning task

This study provides a new perspective on both the cognitive processes actually implemented and the effect of a simple experimental control - the recall constraint - in Sternberg’s memory scanning task. These findings were highlighted by adopting a new approach based on the comparison of qualitative and quantitative results.The analysis of individual processing, on 72 adults, each participating in one of two experimental conditions (with or without sequence recall), highlighted a large variability in quantitative results as well as qualitative procedures. Based on the participants’ retrospective verbalisations, two categories of strategies were identified: (1) the procedures used to memorize the sequence of digits, and (2) the procedures used to compare this sequence with the test digit, which includes strategies for coding the items and processes for searching them in memory. The analysis of the strategies shows that their frequencies of use depend not only on the experimental condition, but also on the participants, the level of task difficulty and the interaction between participants and level of difficulty. This variability questions the accuracy of Sternberg’s mean model. Furthermore, this approach suggests some answers to the old debate concerning the exhaustive search pattern for the yes response. Indeed, our results show three types of strategies that can be identified according to the different models of search suggested in the literature. The “exhaustive” search, that would only be involved in the recall condition and only for some of the participants, the “self-terminating” search and the “immediate” strategy, which can be identified with a model of parallel search with limited resources. Thus our study suggests that the different search models are appropriate but depend on both the specific experimental conditions and participant’s strategy. Our results should help to improve the interpretation of data collected with this paradigm in cognitive and neuroscientific studies of memory.     

Overvaluation of shape and weight in binge eating disorder, bulimia nervosa, and sub-threshold bulimia nervosa

Increasing empirical evidence supports the validity of binge eating disorder (BED), a research diagnosis in the appendix of DSM-IV, and its inclusion as a distinct and formal diagnosis in the DSM-V. A pressing question regarding the specific criteria for BED diagnosis is whether, like bulimia nervosa (BN), it should be characterized by overvaluation of shape and weight. This study compared features of eating disorders in 436 treatment-seeking women comprising four groups: 195 BED participants who overvalue their shape/weight, 129 BED participants with subclinical levels of overvaluation, 61 BN participants, and 51 participants with sub-threshold BN. The BED clinical overvaluation group had significantly higher levels of specific eating disorder psychopathology than the three other groups which did not differ significantly from each other. Findings suggest that overvaluation of shape and weight should not be considered as a required criterion for BED because this would exclude a substantial proportion of BED patients with clinically significant problems. Rather, overvaluation of shape and weight warrants consideration either as a diagnostic specifier or as a dimensional severity rating as it provides important information about severity within BED.     

Think Women, Think Warm: Stereotype Content Activation in Women with a Salient Gender Identity, Using a Modified Stroop Task

We examined whether a salient gender identity activates gender stereotypes along the dimensions of sociability and ability (Fiske et al. 2002). A sample of US undergraduates (40 men, 38 women) instructed to think about women subsequently took longer to name the colors of words associated with sociability than ability on a modified Stroop task. Solo women in another sample of US undergraduates (45 women) showed the same response pattern. Women in a third sample of US adults (20 men, 16 women) showed a similar pattern. Meta-analysis of the three samples suggests women with a salient gender identity experience relative activation of only the positive dimension of a stereotype (e.g. “woman” equals warm).     

Impact of auditory selective attention on verbal short-term memory and vocabulary development

This study investigated the role of auditory selective attention capacities as a possible mediator of the well-established association between verbal short-term memory (STM) and vocabulary development. A total of 47 6- and 7-year-olds were administered verbal immediate serial recall and auditory attention tasks. Both task types probed processing of item and serial order information because recent studies have shown this distinction to be critical when exploring relations between STM and lexical development. Multiple regression and variance partitioning analyses highlighted two variables as determinants of vocabulary development: (a) a serial order processing variable shared by STM order recall and a selective attention task for sequence information and (b) an attentional variable shared by selective attention measures targeting item or sequence information. The current study highlights the need for integrative STM models, accounting for conjoined influences of attentional capacities and serial order processing capacities on STM performance and the establishment of the lexical language network.     

A GENDERED APPROACH TO ADOLESCENT DATING VIOLENCE: CONCEPTUAL AND METHODOLOGICAL ISSUES

This article argues that adolescent dating violence should be considered within a social ecological model that embeds the individual within the context of adolescent friendships and romantic relationships, as well as family and other social institutions that shape a young person's sense of self. Two additions to the model are recommended. First, gender is considered in the model at the individual, interactional and structural levels. Second, identity is treated as a meta-construct, affecting and being affected by all levels of the social ecology. Examples from research are presented and recommendations for future research are offered.     

Consumer reactions to the decreased usage message: The role of elaborative processing

This research examines consumer reactions to an emerging trend among corporate social responsibility initiatives—the promotion of decreased usage of the company's own core products. The results across three experiments suggest that the presence of a decreased usage message that highlights incongruity between the marketing message and the company's goals leads to negative company evaluations. The authors demonstrate that elaborative processing underlies these effects by examining the moderating role of the need for cognition and cognitive load. Further, perceived incongruity and cognitive elaboration mediate the findings. The implications for marketers and consumers are discussed.     

The Case for Creating a DBA Program – A Virtue-based Opportunity for Universities

Although efforts have been made to increase the opportunities for American-born minorities to obtain doctoral degrees in business, the actual number of business students who are American-born minorities has been extremely low. At the same time more than half of all PhD candidates in business schools are foreign-born. We suggest that business schools owe an ethical duty to provide role models for minority business students, and that this duty can be achieved by initiating Doctor of Business Administration (DBA) programs that can enable working professionals who are American-born minorities to obtain terminal degrees in business. We outline eight steps that can be taken to implement a viable and cost effective DBA program.     

Recounting the same events again and again: children's consistency across multiple interviews

Children (2–13 years at time of injury) were interviewed four times about an injury that required hospital Emergency Room treatment, namely at 1 week, 6 months, 1 year, and 2 years. The consistency of children's reports was assessed and all children gave mostly the same information at each interview, although consistency was higher for older children and for injury rather than hospital details. Furthermore, details recalled at every interview were virtually always accurate while details that were sometimes omitted were a little less likely to be accurate. New information that was introduced after 6 months was more likely to be accurate than inaccurate but new information introduced at 1 or 2 years post‐injury was just as likely to be wrong as right (except for 12–13‐year‐olds). Implications for forensic situations are discussed. Copyright © 2001 John Wiley & Sons, Ltd.     

Adolescence-limited versus persistent delinquency: extending Moffitt's hypothesis into adulthood.

The authors examined how neuropsychological, personality, and environmental risk factors and their interactions were related to trajectories of delinquent behavior from adolescence to adulthood. Four waves of longitudinal data from 698 male participants, ages 12-18 at Time 1 and ages 25-31 at Time 4, were included in the analyses. Using a growth mixture model approach, 4 trajectories were identified: nondelinquents, adolescence-limited delinquents, adolescence-to-adulthood-persistent delinquents, and escalating delinquents. Five risk factors distinguished escalating from persistent delinquents and 5 also distinguished nondelinquents from the 3 delinquency trajectories. Persistent delinquents scored significantly higher than adolescence-limited delinquents on only one risk factor, disinhibition. Overall, few of the factors that are related to childhood-to-adolescence persistence were associated with persistence in delinquency beyond adolescence.
