Physiological reactivity to stressors in irritable bowel syndrome patients, inflammatory bowel disease patients and non-patient controls.

Irritable Bowel Syndrome (IBS) patients were compared with Inflammatory Bowel Disease (IBD) patients and non-patient controls on four separate physiological measures (heart rate, finger-tip temperature, skin resistance level, and forehead EMG) for their physical reactivity to 'laboratory stressors'. It was predicted that the IBS patients would respond to these stressors with more physiological reactivity than the two other groups. There were initial basal differences among the groups on heart rate and finger-tip temperature: in general, the IBS patients had lower basal heart rates and the non-patient controls had lower finger-tip temperatures. These findings are contrary to the previous body of literature regarding possible sympathetic nervous system (SNS) arousal states in the IBS patient. The results also indicated IBS patients were not significantly different than the IBD patients or the non-patient controls in their reactivity to stressors. Previous literature has suggested that IBS in their reactivity to stressors. Previous literature has suggested that IBS patients have an enhanced SNS arousal or an SNS mediated reactivity to environmental stressors, our current study has not found these results.     

Attributions About Rape: Effects of Rapist Force, Observer Sex and Sex Role Attitudes

The present study investigated subjects' perceptions of a hypothetical rape situation as a function of the amount of force used in the rape, sex of subject, and subjects' attitudes toward feminism. Two hundred thirty-two subjects (118 females, 114 males) were randomly assigned by sex to one of three force conditions. Consistent with expectation, subjects expressed greater certainty that a rape had actually occurred with increased force on the part of the assailant ( p <.001). A second hypothesis received partial support: Increasing force led to stronger attributions of rape on the part of traditional women, whereas liberal women tended to see the incident as rape at all force levels. A similar relationship did not emerge for men, however. As predicted, profeminist subjects implicated societal factors as causal in rape to a greater extent than did nonfeminists. Contrary to prediction, however, pro- and nonfeminists were not found to differ from each other in the degree of blame attributed to either the victim or the assailant. The findings support the general notion that one's gender and sex-role attitudes as well as the degree of force used by a rape assailant affect one's evaluation of this situation and the manner in which one attributes cause. Implications for rape prevention and victim reaction are discussed.     

Selective disruption of hypermnesia for pictures and words

In this study, we investigated the effects of various interpolated tasks on hypermnesia (improved recall across repeated tests) for pictures and words. In five experiments, subjects studied either pictures or words and then completed two free-recall tests, with varying activities interpolated between the tests. The tasks performed between tests were varied to test several hypotheses concerning the possible factor(s) responsible for disruption of the hypermnesic effect. In each experiment, hypermnesia was obtained in a control condition in which there was no interpolated task between tests. The remaining conditions showed that the effect of the interpolated tasks was related to the overlap of the cognitive processes involved in encoding the target items and performing the interpolated tasks. When pictures were used as the target items, no hypermnesia was obtained when subjects engaged in imaginal processing interpolated tasks, even when these tasks involved materials that were very distinct from the target items. When words were used as the target items, no hypermnesia was obtained when the interpolated tasks required verbal/linguistic processing, even when the items used in these tasks were auditorily presented. The results are discussed in terms of a strength-based model of associative memory.     

Sleep preferentially enhances memory for emotional components of scenes

ABSTRACT— Central aspects of emotional experiences are often well remembered at the expense of background details. Previous studies of such memory trade-offs have focused on memory after brief delays, but little is known about how these components of emotional memories change over time. We investigated the evolution of memory for negative scenes across 30 min, 12 daytime hours spent awake, and 12 nighttime hours including sleep. After 30 min, negative objects were well remembered at the expense of information about their backgrounds. Time spent awake led to forgetting of the entire negative scene, with memories of objects and their backgrounds decaying at similar rates. Sleep, in contrast, led to a preservation of memories of negative objects, but not their backgrounds, a result suggesting that the two components undergo differential processing during sleep. Memory for a negative scene develops differentially across time delays containing sleep and wake, with sleep selectively consolidating those aspects of memory that are of greatest value to the organism.     

What Mistakes Disclose: A Process Dissociation Approach to Automatic and Controlled Processes in Social Psychology

Process dissociation is a model for separating automatic and controlled contributions to responses in a single task. Although it was developed to separate conscious and unconscious uses of memory, researchers have increasingly found the model useful to answer questions in social psychology. This article reviews process dissociation studies with a focus on social psychology. It emphasizes the model's conceptual definitions of automatic and controlled processing and how those relate to procedures for estimating them. Process dissociation is contrasted with task dissociation, in which automatic and controlled processes are identified with implicit and explicit tasks. Current trends and future directions are identified, including the use of model testing procedures to compare competing theories of how automatic and controlled processes interact.     

An Analysis of Group-Oriented Contingencies and Associated Side Effects in Preschool Children

Group-oriented contingencies are arranged to target the behavior of a group of people simultaneously. Overall, group-oriented contingencies have been shown to be effective in both decreasing problem behavior and increasing appropriate behavior. However, results are mixed regarding which type(s) of group-oriented contingency is most effective for changing behavior. In addition, although there are anecdotal reports of positive and negative side effects when using group-oriented contingencies, little research has involved direct measurement of these potential side effects. The purposes of the current study were to (a) compare the effects of three types of group-oriented contingencies for increasing on-task behavior and decreasing problem behavior, (b) determine whether implementing a group-oriented contingency for one behavior resulted in changes in a non-targeted behavior, and (c) determine how often and under what conditions side effects occurred within group-oriented contingencies conditions for two groups of preschool children. The results of the study were mixed. The results suggested that group-oriented contingencies were effective in decreasing problem behavior and increasing on-task behavior, but varied across groups as to which contingencies were the most effective at changing both behaviors. Secondary data suggested that side effects were associated with group-oriented contingencies, as well as the occurrence of problem behavior and reinforcer delivery.     

Racial Attitudes Predicted Changes in Ostensibly Race‐Neutral Political Attitudes Under the Obama Administration

Past research demonstrated that racial prejudice played a significant role in the 2008 presidential election, but relatively less is known about the relationship between prejudice and public opinion throughout the Obama administration. In the present research, we examined not only whether racial attitudes were associated with evaluations of Mr. Obama and his administration, but also whether they may have influenced the development of more general political attitudes during the early years of the Obama administration. We investigated this question using panel data from a nationally representative sample of Americans interviewed between September 2008 and July 2010. Racial attitudes measured prior to the election predicted early disapproval of President Obama's handling of important issues. Early disapproval of President Obama's performance, in turn, predicted later perceptions of whether the state of the nation was improving. Further, the divergence between high‐prejudice and low‐prejudice individuals in their perceptions of the state of the nation became greater over time, consistent with the idea that racial attitudes were more powerfully expressed in political judgments as time passed.     

A meta-analytic examination of the goal orientation nomological net

The authors present an empirical review of the literature concerning trait and state goal orientation (GO). Three dimensions of GO were examined: learning, prove performance, and avoid performance along with presumed antecedents and proximal and distal consequences of these dimensions. Antecedent variables included cognitive ability, implicit theory of intelligence, need for achievement, self-esteem, general self-efficacy, and the Big Five personality characteristics. Proximal consequences included state GO, task-specific self-efficacy, self-set goal level, learning strategies, feedback seeking, and state anxiety. Distal consequences included learning, academic performance, task performance, and job performance. Generally speaking, learning GO was positively correlated, avoid performance GO was negatively correlated, and prove performance GO was uncorrelated with these variables. Consistent with theory, state GO tended to have stronger relationships with the distal consequences than did trait GO. Finally, using a meta-correlation matrix, the authors found that trait GO predicted job performance above and beyond cognitive ability and personality. These results demonstrate the value of GO to organizational researchers.
