Set similarity modulates object tracking in dynamic environments

Based on the observation that sports teams rely on colored jerseys to define group membership, we examined how grouping by similarity affected observers’ abilities to track a “ball” target passed between 20 colored circle “players” divided into two color “teams” of 10 players each, or five color teams of four players each. Observers were more accurate and exerted less effort (indexed by pupil diameter) when their task was to count the number of times any player gained possession of the ball versus when they had to count only the possessions by a given color team, especially when counting the possessions of one team when players were grouped into fewer teams of more individual members each. Overall, results confirm previous reports of costs for segregating a larger set into smaller subsets and suggest that grouping by similarity facilitates processing at the set level.     

When people fall from grace: reconsidering the role of envy in Schadenfreude

Previous research yielded conflicting results concerning the role of envy in predicting Schadenfreude (pleasure at another's misfortune). Some studies showed that envy predicts Schadenfreude, whereas others did not. Results of the present research reconcile these opposing findings, by showing that envy is a predictor of Schadenfreude when the target is similar to the observer in terms of gender. These results suggest that envy predicts Schadenfreude when people are confronted with the misfortune of a relevant social comparison other.     

Memory for time: How people date events

The effect of different formats on the accuracy of dating news and the distribution of personal events was examined in four conditions. In the first, participants had to date events in the absolute time format (e.g., "July 2004"), and in the second, they had to date events in the relative time format (e.g., "3 weeks ago"). In the other conditions, they were asked to choose between the two formats. We found a small backward telescoping effect for recent news events and a large forward telescoping effect for remote events. Events dated in the absolute time format were more accurate than those dated in the relative time format. Furthermore, participants preferred to date news events with the relative time format and personal events with the absolute time format, as well as preferring to date remote events in the relative time format and recent events in the absolute time format.

In this study, changes in movement coordination caused by fatigue that developed during repetitive lifting were examined. Five men performed 6 times a 5-min bout of lifting an 8-kg barbell at 15 lifts/min, using two lifting techniques; one minimized trunk rotation (squat lift), and the other minimized rotation in the knee joint (stoop lift). Kinematics and dynamics were studied by means of movement analysis and inverse dynamics, using a two-dimensional linked segment model. Within-subject variation over repetitive lifts of the time course of joint angles was smaller than between-subjects variation on the first analyzed lift. Relative timing between joint rotations did not change significantly across repetitive lifts, except between knee and hip in the squat lift. No change of the lumbosacral torque over repetitive lifts was found. The adaptability of the neural control appeared to be sufficient to accommodate the strong changes of the input-output characteristics of the muscles caused by fatigue so that an essentially constant performance of the movement act was maintained.     

Development and Validation of a Dutch Translation of the Big Five Inventory (BFI)

The MMPI profiles of 74 low back pain patients who had previously been classified as "functional," "organic," or "mixed" were sorted into six profile groups. The six profile groups were those used by Pichot, Perse, Lekeous, Dureau, Perez, and Rychewaert (1972); denial, "conversion V" without defensiveness, "conversion V" with defensiveness, depressed/anxious, psychotic and normal. Results indicate that all six profile types are welt represented in the low back pain group. Evidence is also presented which shows that each of the pathological MMPI profile types examined across "functional," "organic," and "mixed" classification is significantly more elevated than a normal profile group on two scales (Lb, DOR) designed to measure functional aspects of pain. Pathological MMPI profile groups did not differ significantly from each other on the "functional," pain scales. The data presented in this study point to the relationship of various forms of psychopathology with "functional pain." The findings of this stud v would not support a homogeneous "pain personality" for low back pain patients. However, combined "conversion V" profiles accounted for 58% of the "functional" group, 45% of the "mixed" group and 35% of the "organic" group.     

Are Actual and Perceived Intellectual Self‐enhancers Evaluated Differently by Social Perceivers?

Do actual and perceived self‐enhancement entail differing social impressions (i.e. interpersonal evaluations)? Actual self‐enhancement represents unduly positive self‐views, as gauged by an objective criterion (in this case, IQ scores), whereas perceived self‐enhancement involves the extent to which an individual is seen by informants (i.e. peers or observers) as self‐enhancing. In an online survey (N = 337), a laboratory experiment (N = 75), and a round‐robin study (N = 183), we tested the effects of actual and perceived intellectual self‐enhancement on (informant‐rated) emotional stability, social attractiveness, and social influence. Actual self‐enhancers were rated as emotionally stable, socially attractive, and socially influential. High perceived self‐enhancers were judged as socially influential, whereas low‐to‐moderate perceived self‐enhancers were deemed emotionally stable and socially attractive. Privately entertained, illusory positive (even extreme) self‐beliefs confer social benefits, whereas being perceived as self‐enhancing buys social influence at the cost of being despised.

Smart and easy: Co-occurring activation of spontaneous trait inferences and spontaneous situational inferences

Social perceivers have been shown to draw spontaneous trait inferences (STI’s) about the behavior of an actor as well as spontaneous situational inferences (SSI’s) about the situation the actor is in. In two studies, we examined inferences about behaviors that allow for both an STI and an SSI. In Experiment 1, using a probe recognition paradigm, we found activation of both STI’s and SSI’s. In Experiment 2, using a relearning paradigm, we again found activation of both STI’s and SSI’s, regardless of temporarily activated processing goals. Results are discussed in light of three-stage models of the process of social inference.     

Towards understanding pleasure at the misfortunes of others: The impact of self-evaluation threat on schadenfreude

In two experiments we demonstrated that a self-evaluation threat intensifies schadenfreude. Moreover, we showed that a self-evaluation threat predicts schadenfreude in both threat-related and threat-unrelated domains and when controlling for feelings of envy and dislike towards the target and evaluations of the misfortune in terms of deservingness. These findings indicate that another's misfortune may be pleasing because it satisfies people's concern for a positive self-view and a sense of self-worth.
