THE NEED FOR POWER IN WOMEN WHO WERE SEXUALLY ABUSED AS CHILDREN An Exploratory Study

Ten women who had been sexually abused as children and a matched group of women who had not been sexually abused participated in a preliminary study to explore the hypothesis that feelings of powerlessness and a compensatory need for power continue into adulthood for survivors of childhood sexual abuse. The Picture-Story Exercise (PSE) was used as an indirect assessment technique to determine the level of the need for power (McClelland, 1985; Winter, 1973, 1988). Results indicated that the stories of women with sexual abuse histories revealed a higher need for power and greater fear of power than those of nonabused women. Further content analysis of the PSE revealed that sexual abuse survivors' stories also contained more references to Finkelhor and Browne's (1986) dynamics of powerlessness, traumatic sexualization, betrayal, and stigmatization. These findings suggest important directions for future research as well as areas for therapeutic exploration.     

Emotional context at learning systematically biases memory for facial information

Emotion influences memory in many ways. For example, when a mood-dependent processing shift is operative, happy moods promote global processing and sad moods direct attention to local features of complex visual stimuli. We hypothesized that an emotional context associated with to-be-learned facial stimuli could preferentially promote global or local processing. At learning, faces with neutral expressions were paired with a narrative providing either a happy or a sad context. At test, faces were presented in an upright or inverted orientation, emphasizing configural or analytical processing, respectively. A recognition advantage was found for upright faces learned in happy contexts relative to those in sad contexts, whereas recognition was better for inverted faces learned in sad contexts than for those in happy contexts. We thus infer that a positive emotional context prompted more effective storage of holistic, configural, or global facial information, whereas a negative emotional context prompted relatively more effective storage of local or feature-based facial information     

Suicide Attempts in Preadolescent Child Psychiatry Inpatients

This paper describes a preliminary study examining the relative power of measures of perceived family support, hopelessness, and depression for the classification of suicide attempters and nonattempters in a series of 8- to 13-year-old psychiatric inpatients. Results of a stepwise discriminant-function analysis indicated that a measure of a child's perceived family support discriminated between suicide attempters and nonattempters with an 88% accuracy rate. The addition of measures of hopelessness and depression at later steps did not lead to improved classification. The results are interpreted as providing strong support for a link between suicide attempts in children and perceptions of low family support.     

Images of exercising: Exploring the links between exercise imagery use, autonomous and controlled motivation to exercise, and exercise intention and behavior

Objectives

In the present study, we tested a model examining the relationships between exercise imagery use, motivational regulations for exercise engagement, intention to exercise, and self-reported exercise behavior. This work represents an initial attempt to examine relationships between a new type of exercise imagery (enjoyment imagery) and motivational regulations for exercise.

Design

Cross-sectional.

Method

Exercisers with a mean age of 40.29 years (SD = 13.29; 177 female, 141 male) completed measures of the targeted variables.

Results

Structural equation modeling analyses revealed direct and indirect (via motivational regulations) links between imagery and exercise-related outcomes. Technique and enjoyment imagery were positively related to autonomous motivation. Conversely, appearance imagery was positively associated with controlled motivation. Direct relationships were evidenced between energy imagery and self-reported exercise behavior, and between appearance imagery and intention to exercise.

Conclusions

The potential motivational functions served by different exercise imagery types are discussed, and the inclusion of enjoyment imagery in future exercise imagery research is recommended.     

Salience modulation in serial preexposure: implications for perceptual learning

In three experiments rats were given serial preexposure to two flavor stimuli. In Experiment 1, some animals were given exposure to AX followed by the presentation of BX, a forward schedule; the others were given backward preexposure (BX→AX). Conditioning and test trials with the A element showed that salience or effectiveness of A was better protected in the forward than in the backward condition. Experiments 2 and 3 assessed the relevance of this salience modulation mechanism for perceptual learning. In these experiments, generalization of a conditioned aversion from AX to BX was reduced in the forward (but not in the backward) condition only after prolonged exposure, indicating that the establishment of an inhibitory link from B to A is required for successful discrimination. However, generalization to a novel compound stimulus, NX, was reduced in the forward group both after short and long preexposure, suggesting the existence of salience modulation processes that work in parallel with associative inhibition. These results seem to support the existence of a salience modulation mechanism that seems to be beyond the scope of current theories of perceptual learning.
