Information search and mental representation in risky decision making: The advantages first principle

In three experiments the problem is investigated how people identify early in the decision process those alternatives that are worthwhile to be examined in more detail. We assume that decision makers employ the Advantages first Principle: They first search for information about positive outcomes and then focus their information search (e.g., for negative consequences or for risk defusing operators) on those alternatives that appear attractive after this initial evaluation. In Experiment 1 (120 participants), initial information about consequences was varied for eight alternatives (no information, positive consequences, negative, or mixed for four alternatives). In all conditions, the great majority of participants followed both aspects of the Advantages first Principle. In Experiment 2, 60 participants decided in two quasi‐realistic scenarios with two alternatives each. Initial information was presented so that one alternative had better positive consequences, worse negative consequences, or both. In all conditions, more information was searched for in the initially better alternative. In Experiment 3 (20 participants) the Advantages first Principle was not only confirmed for a scenario but also for choices in traditional gambling tasks with two and eight alternatives, respectively. Participants could win or lose real money. Copyright © 2010 John Wiley & Sons, Ltd.     

Understanding Anti‐Arab Reactions Post‐9/11: The Role of Threats,Social Categories,and Personal Ideologies1

This study examined social psychological processes associated with anti‐Arab reactions (prejudice, stereotypes, and discrimination) following the September 11 terrorist attacks. Participants (N= 201) responded to an online survey. Perceived threats, self‐categorization, social dominance orientation, and just‐world beliefs were tested for their effectiveness in predicting anti‐Arab reactions. The results reveal that self‐categorization and social dominance orientation each individually accounted for a substantial percentage of the variance, while perceived threats accounted for a relatively small amount of the variance in anti‐Arab responses. However, an integrated model demonstrated that social dominance orientation, threats, self‐categorization, and a threat by self‐categorization interaction provided the best prediction of anti‐Arab reactions. Results are discussed in terms of the theoretical and practical applications for understanding out‐group derogation following political‐cultural world events.     

Comparing Personality Test Formats and Warnings: Effects on criterion‐related validity and test‐taker reactions

The potential for applicant response distortion on personality measures remains a major concern in high‐stakes testing situations. Many approaches to understanding response distortion are too transparent (e.g., instructed faking studies) – or are too subtle (e.g., correlations with social desirability measures as indices of faking). Recent research reveals more promising approaches in two methods: using forced‐choice (FC) personality test items and warning against faking. The present study examined effects of these two methods on criterion‐related validity and test‐taker reactions. Results supported incremental validity for an FC and Likert‐scale measure in warning and no‐warning conditions, above and beyond cognitive ability. No clear differences emerged between the FC vs Likert measures or warning vs no‐warning conditions in terms of validity. However, some evidence suggested that FC measures and warnings may produce negative test‐taker reactions. We conclude with implications for implementation in selection settings.     

Best friends forever?: High school best friendships and the transition to college

The transition from high school to college is an important phase for adolescents in social as well as academic aspects. This study examined the changes that occur in high school best friendships during the first year of college. Results revealed that during the first year in college high school best friendships declined in satisfaction, commitment, rewards, and investments. During this period there was also an increase in costs and alternatives to best friend relationships. Proximity did not influence the friendships; however, level of communication did moderate friendship deterioration. Furthermore, individuals who continued their best friendship reported engaging in more maintenance behaviors of positivity, supportiveness, self‐disclosure, and interaction than individuals who reported a change in the relationship to close or casual friendship. Maintaining the best friendship also appeared to buffer adolescents from social loneliness. The results are discussed in terms of the implications of transitions on adolescent friendships.

Body Composition And Human Sleep

It has been reported that fit atheletes have more slow wave sleep (SWS), sleep longer and have shorter sleep onset latencies than unfit individuals. However, we have shown that these differences are not a direct consequence of physical fitness. This suggests that the effect is due to more enduring characteristics of individuals. We report two experiments designed to test the hypothesis that individual differences in sleep are related to differences in body composition. The hypothesis was tested in two different experiments, each comparing independent groups of fit athletes with unfit non-athletes. In each experiment both sleep and a number of anthropometric variables were measured. Twenty-five fit and 22 unfit subjects were run in Experiment 1 and 17 fit and 17 unfit in Experiment 2. In Experiment 1 percentage fat was estimated from a skin fold method, while in Experiment 2 lean body mass (LBM) was estimated from 24 h. urinary creatinine. The results showed that percentage LBM was negatively related to SWS in fit subjects, while the amount of LBM and weight were negatively related in the unfit groups. When all subjects were combined within each experiment, significant negative correlations were found between SWS and both LBM and percentage LBM in Experiment 2. The results suggest that body composition influences SWS levels, but not other components of sleep.     

Punitive Reactions to Completed Crimes Versus Accidentally Uncompleted Crimes1

Previous studies have shown that the harm caused by crime affects punitive reactions even if differences in the degree of harm are merely accidental. However, it remains unclear whether the effect is direct or whether it is mediated by attributed responsibility or blame. Participants were 303 university students who listened to 4 case vignettes (between‐subjects design). Half received information about a completed crime and half about an accidentally uncompleted crime. Crime type was either fraud or rape. The results suggest that individuals consider the actual harm to a significantly greater extent than attribution theory would predict. Moreover, the link between harm and punishment was virtually not mediated by attributed blame and not moderated by individual differences in morality. Future studies should investigate whether the harm‐punishment link is a result of an automatic act of retaliation or a desire to compensate for the harm done to the victim (restorative justice).     

Using temporal order to identify spatial reference frames

A new method for identifying spatial reference frames is described and applied to the study of spatial span. In this method, a spatial sequence is displayed in relation to two reference frames that move relative to each other, so that different temporal orders are described in each reference frame. As applied to spatial span, a sequence of dots was displayed on a rectangular template that moved relative to the computer screen and the observer. Three experiments showed that the choice of reference frame is influenced by prior conditions, the size of the template, and the presence of an alternative stationary reference frame. Recall was impaired (1) when the template moved, suggesting that movement interference occurred, and (2) with increasing template size, but only if the template was used as the reference frame.     

Community-based instruction for independent meal preparation by adults with profound mental retardation

Three adults with profound mental retardation and very limited reading skills were transitioned to community living after spending more than 20 years in a residential facility. Community-based instruction was used to teach them to independently prepare meals. Directed rehearsal and prompting procedures were used to teach them those meal preparation skills that they were unable to perform independently. We present assessment, training and followup data on the preparation of a dessert by the three participants. Following an assessment on the steps needed to prepare the dessert, training was introduced in a multiple baseline across subjects design. Results showed that the participants were able to independently prepare the dessert in up to 21 pre-training and training sessions. Monthly followup for six months showed that they were able to independently prepare the dessert in various community settings of their choice.
