Performance boosts in the classroom: Stereotype endorsement and prejudice moderate stereotype lift

The present study (N = 293) examined whether stereotype endorsement and prejudice moderate stereotype lift (i.e., a performance boost caused by the salience of a negative out-group stereotype in the testing situation). The stereotype in the focus of inquiry was the belief that immigrant students have lower intellectual ability than native students. French native high school students performed an intellectual test in a condition of low stereotype salience (the test was presented as assessing individual differences) or in a condition of high stereotype salience (the test was presented as assessing group differences between African immigrants and native students). As expected, results indicated that native students high in stereotype endorsement and those high in prejudice performed better in the high than in the low stereotype salience condition, whereas those low on these constructs did not. By identifying two moderators of stereotype lift, this study sheds new light on the achievement gap between immigrant and native students in educational institutions.     

The format in which uncertainty information is presented affects decision biases

We examined how the format in which uncertainty information is presented affects two biases in humans' choice behavior. In a computer task, participants were given four common-ratio effect and four common-consequence effect problems in each of four different formats. In these problems, uncertainty information was described, as percentages (e.g., 80%) or as frequencies (e.g., 16/20), or was experienced, either serially (20 outcomes shown one at a time) or simultaneously (20 outcomes all shown at once). Presenting information as percentages attenuated the common-ratio effect and augmented the common-consequence effect, which suggests that these biases have different underlying mechanisms. Participants' percentage estimates of outcome likelihoods did not differ according to the format in which the information was presented; however, participants' nonverbal estimates of outcome likelihoods differed across formats. The results suggest that uncertainty information presented as percentages is processed differently than the same uncertainty information presented in other formats.     

Rorschach Comprehensive System data for a sample of 75 Danish 9-year-old children: a pilot study

This article provides a normative study documenting how 75 Danish nonpatient 9-year-old children respond to the Rorschach test. The children were selected randomly from nine different parts of Denmark and tested with the Rorschach by 10 different psychologists. All examiners were familiar with the Comprehensive System (CS; Exner, 2003), and before the data collection they participated in a 3-day workshop performed by the research group that focused on administration, inquiry, and scoring issues. Among the results are an average R of 23.6 and an average Lambda of 2.01 (median = 1.18). Slightly more than 60% of the sample had an Avoidant style (63%); 41% had a CDI of 4 or 5; and 33% were positive on the HVI. In terms of perception and thinking, average values were .44 for X+%, .27 for X-%, and 9.4 for the WSum6.     

Learning is impaired by activated intentions

Two experiments examined the task interference that sometimes accrues from having an intention. In standard prospective memory tasks, latency is often slower to an ongoing task performed concurrently with having an intention than it is when no intention is given. If the locus of this slowing resulted from different attentional allocation policies in the two cases, we predicted that the process of learning a word list would be impaired if participants had an intention rather than if they did not. Four different event-based prospective memory tasks were used in Experiment 1 to demonstrate that worse free recall of a word list resulted when studied with a concurrent intention than with a control condition that had no intention. In that experiment, linking an intention to a distal context that was to occur after learning did not impair free recall. Two time-based tasks were used in Experiment 2 to demonstrate that possessing a time-based prospective memory also hinders learning, unless the intention is linked to a future context that is expected to occur after the study session. In the latter case, no impairment was obtained.     

Aging and situation model processing

Over the past several years, a number of studies have been done that assess processing at the level of the situation model in relation to issues of aging (Morrow, Leirer, & Altieri, 1992; Radvansky, Copeland, Berish, & Dijkstra, 2003; Radvansky, Copeland, & Zwaan, 2003; Stine-Morrow, Gagne, Morrow, & DeWall, 2004; Stine-Morrow, Morrow, & Leno, 2002). In contrast to age-related declines that have been demonstrated at surface form and textbase levels of processing, no such declines have been found in the creation and updating of situation models (Radvansky, 1999). This review focuses on the relevant factors in cognitive aging and situation model processing and places them within the larger frameworks of language processing, working memory capacity, and aging.     

To prove or to improve? Which motive distorts perceptions of personality controllability?

This research extends past work on positive illusions and self-goals by examining motivated perceptions of how much control people think they have over changing their personality traits. A self-validation motivation should cause individuals to view their personality weaknesses as uncontrollable (to avoid blame for having them) and their personality strengths as controllable (to take credit for having them). A self-growth motivation should cause individuals to view their weaknesses as controllable (to view them as improvable) and their strengths as uncontrollable (to view them as unchanging). Studies 1 and 2 find evidence for self-validation in perceptions of trait controllability. Study 3 finds this pattern to be stronger for validation-seeking individuals but weaker for growth-seeking individuals. Studies 3 and 4 find that being primed with one's successful self-improvements or one's future self can attenuate the self-validation. The potential implications of distorted perceptions of trait controllability for both well-being and self-change are discussed.     

Development and initial validation of a measure of supportive and unsupportive managerial behaviors

Studies documenting the positive consequences of managerial support have continued unabated, despite considerable ambiguity surrounding the conceptualization of this construct and the adoption of measures that lack specificity. Moreover, research on the positive effects of managerial support has overshadowed our understanding of the ways in which managers contribute to job strain. In order to address these gaps, we took an inductive approach, documenting supportive, and unsupportive managerial behaviors reported by a sample of 25 employees working in a variety of occupations. We subsequently developed a new measure of supportive and unsupportive managerial behaviors and validated it with two separate samples (N = 100; N = 247). The measure demonstrated strong internal reliability and convergent validity. Factor analysis of the measure yielded a two-factor model of support and a one-factor structure of unsupportive behaviors. Theoretical and organizational implications of the findings are discussed.     

Grasping the Nature of Pictures

The role of experience in the development of pictorial competence has been the center of substantial debate. The four studies presented here help resolve the controversy by systematically documenting and examining manual exploration of depicted objects by infants. We report that 9-month-old infants manually investigate pictures, touching and feeling depicted objects as if they were real objects and even trying to pick them up off the page. The same behavior was observed in babies from two extremely different societies (the United States and the Ivory Coast). This investigation of pictures occurs even though infants can discriminate between real objects and their depictions. By the time infants are 19 months of age, their manual exploration is replaced by pointing at depicted objects. These results indicate that initial uncertainty about the nature of pictures leads infants to investigate them. Through experience, infants begin to acquire a concept of "picture." This concept includes the fact that a picture has a dual nature (it is both an object and a representation of something other than itself), as well as knowledge about the culturally appropriate use of pictures.
