Evidence for utilitarian motives in emotion regulation

This investigation demonstrates that emotion regulation can be driven by considerations of utility per se. We show that as participants prepared for a negotiation, those who were motivated to confront (vs. collaborate with) another person believed that anger would be more useful to them. However, only participants who were motivated to confront another and expected to receive a monetary reward for their performance (i.e., high utility), were motivated to increase their anger in preparation for the negotiation. Participants who were motivated to confront another but did not expect their performance to be rewarded (i.e., low utility), did not try to increase their anger, even though they expected anger to be useful in the negotiation. Such patterns demonstrate that people are motivated to experience even unpleasant emotions to maximise utility.     

The antecedents and correlates of agreeableness in adulthood

Data from a 25-year prospective study of 194 individuals indicated that teacher and peer reports of aggression, compliance, and self-control at age 8 distinguished high-agreeable from low-agreeable adults at age 33. Profile analyses revealed two behavioral types in childhood and two personality types in adulthood, with considerable continuity in the composition of these high- and low-agreeable types over time. High-agreeable childhood types had fewer disobedience and concentration problems than low-agreeable childhood types, and among boys, high-agreeable childhood types had better school grades and fewer behavior problems than their low-agreeable counterparts. High-agreeable adulthood types reported less alcoholism and depression, fewer arrests, and more career stability than did low-agreeable adulthood types.     

REM restriction persistently alters strategy used to solve a spatial task

We tested the hypothesis that rapid eye movement (REM) sleep is important for complex associative learning by restricting rats from entering REM sleep for 4 h either immediately after training on an eight-box spatial task (0-4 REMr) or 4 h following training (4-8 REMr). Both groups of REM-restricted rats eventually reached the same overall performance level as did nonrestricted controls, but 0-4 REMr animals were delayed in their improvement in the first few days and lagged behind controls in the middle portion of the training period. More importantly, performance gains of 0-4 REMr rats depended more on simple local cues throughout the 15-d study since, unlike control and 4-8 REMr animals, their error rate increased after daily disruption of the relationship between local (intramaze) cues and the food reward. Thus, although overall performance was only subtly and transiently impaired, due to the ability to use alternate, nonspatial behavioral strategies, complex associative (spatial) learning was persistently impaired by restricting REM for a short critical period each day.     

Comparing Child Outcomes of Physical Punishment and Alternative Disciplinary Tactics: A Meta-Analysis

This meta-analysis investigates differences between the effect sizes of physical punishment and alternative disciplinary tactics for child outcomes in 26 qualifying studies. Analyzing differences in effect sizes reduces systematic biases and emphasizes direct comparisons between the disciplinary tactics that parents have to select among. The results indicated that effect sizes significantly favored conditional spanking over 10 of 13 alternative disciplinary tactics for reducing child noncompliance or antisocial behavior. Customary physical punishment yielded effect sizes equal to alternative tactics, except for one large study favoring physical punishment. Only overly severe or predominant use of physical punishment compared unfavorably with alternative disciplinary tactics. The discussion highlights the need for better discriminations between effective and counterproductive use of disciplinary punishment in general.     

Applying bubbles to localize features that control pigeons' visual discrimination behavior

The authors trained pigeons to discriminate images of human faces that displayed: (a) a happy or a neutral expression or (b) a man or a woman. After training the pigeons, the authors used a new procedure called Bubbles to pinpoint the features of the faces that were used to make these discriminations. Bubbles revealed that the features used to discriminate happy from neutral faces were different from those used to discriminate male from female faces. Furthermore, the features that pigeons used to make each of these discriminations overlapped those used by human observers in a companion study (F. Gosselin & P.G. Schyns, 2001). These results show that the Bubbles technique can be effectively applied to nonhuman animals to isolate the functional features of complex visual stimuli.     

A relevance theory of induction

A framework theory, organized around the principle of relevance, is proposed for category-based reasoning. According to the relevance principle, people assume that premises are informative with respect to conclusions. This idea leads to the prediction that people will use causal scenarios and property reinforcement strategies in inductive reasoning. These predictions are contrasted with both existing models and normative logic. Judgments of argument strength were gathered in three different countries, and the results showed the importance of both causal scenarios and property reinforcement in categorybased inferences. The relation between the relevance framework and existing models of category-based inductive reasoning is discussed in the light of these findings.     

Validity and reliability of the general well-being schedule with northern plains American Indians diagnosed with type 2 diabetes mellitus

The General Well-being Schedule is a brief indicator of subjective feelings of psychological well-being and distress. It is easy to administer, reliable, and valid, although its validity with American Indians has not been established. This study then assessed reliability, validity, and factor structure for a sample of 88 diabetic American Indians, who sought care for diabetes at an Indian Health Service hospital. Cronbach alpha was .89. A factor analysis indicated four dimensions. Adequate concurrent and divergent validity were noted in association with scores on the Beck Depression Inventory-Second Edition, the depression scale on the Symptom Checklist-90-Revised, and Family-Adaptation, Partnership, Growth, Affection, & Resolve. These results suggest that the General Well-being Schedule is a reliable and valid measure of general well-being for this population of American Indians.     

Pigeons learn stimulus identity and stimulus relations when both serve as redundant,relevant cues during same-different discrimination training

The authors taught pigeons to discriminate displays of 16 identical items from displays of 16 nonidentical items. Unlike most same-different discrimination studies--where only stimulus relations could serve a discriminative function--both the identity of the items and the relations among the items were discriminative features of the displays. The pigeons learned about both stimulus identity and stimulus relations when these 2 sources of information served as redundant, relevant cues. In tests of associative competition, identity cues exerted greater stimulus control than relational cues. These results suggest that the pigeon can respond to both specific stimuli and general relations in the environment.     

Working 61 plus hours a week: why do managers do it?

The authors investigated why some managers work extreme hours, defined as 61 or more hours per week. The authors tested explanations drawn from theories including the work-leisure tradeoff, work as an emotional respite, social contagion, and work as its own reward. In a demographically homogeneous sample of male managers, the best explanations for why some worked 61 or more hours per week were the financial and psychological rewards they received from doing so. The hypothesis derived from A. Hochschild's (1997) research that managers who work long hours seek relief at work from pressures at home was not supported. Findings in a small sample of managerial women were consistent with the work-leisure trade-off hypothesis, the social contagion hypothesis, and the work as its own reward hypothesis.
