Further evaluation of prompt density,rate of reinforcement,and the persistence of manding

Previous research has evaluated the effects of prompt rates on the rate of communicative behavior. More recent research has suggested that dense prompting can result in communicative behavior that is more resistant to change. However, existing research has not considered the impact that higher response rates had on reinforcement rate, a variable known to impact response persistence. The current study systematically replicated previous research by evaluating communicative responding in contexts associated with dense- and lean-prompt schedules and extended existing research by (a) holding reinforcement rates similar across the two prompting schedules (lean and dense), and (b) evaluating the persistence of communicative responding in the contexts associated with each prompting schedule. The results for Experiment 1 clearly replicated and extended previous research. The results for Experiment 2 were equivocal and suggested that previous reinforcement history and response class size impacted outcomes.     

The effect of pressurized air in establishing discriminative response suppression in stump-tailed macaques

Pressurized air was repeatedly associated with one of two frequencies of flashing light during performance of a VI 30-sec positive reinforcement schedule by stump-tailed monkeys. As revealed by the relative suppression of bar presses to each of the two visual stimuli, the Ss learned to discriminate between the different flicker frequencies. However, they also showed signs of adapting to the airblast during the course of training, and its location had to be changed in order to maintain discriminative suppression.     

Factors Affecting Stayers’ Job Satisfaction in Response to a Coworker Who Departs for a Better Job1

Two studies examined the consequences of turnover, by investigating factors affecting the job satisfaction of people who remain (i. e., stayers) in response to a coworker (i. e., leaver) who departed for a better job. Consistent with Tesser and Campbell's (1983) self-esteem maintenance model, three factors were found to influence the job satisfaction level of stayers: (a) the extent to which they compared their job situation to the leaver's new one, which was negatively related to stayers’ level of satisfaction, (b) the relevance of the leaver to the stayer for social comparison purposes, which was negatively related to the stayers’ level of satisfaction, and (c) the stayers’ trait self-esteem, which was positively related to the stayers’ level of job satisfaction. Theoretical implications, limitations, and future research directions are discussed.     

Stressors, Stress Mediators, and Emotional Weil-Being Among Spouses of Soldiers Deployed to the Persian Gulf During Operation Desert Shield/Storm

The Family Factors Field Study of Operation Desert Shield/Storm (ODS) was designed to collect data on the impact of the Persian Gulf deployment on soldier/family well-being, and the effectiveness of Army and community resources in assisting and supporting families of deployed soldiers. In October 1990, a task force was assembled, and multi-agency research teams visited several Army installations. Informal individual and group interviews were conducted with spouses, unit family support leaders, unit rear detachment personnel, garrison leaders, and local Army program/service providers. The questions were aimed at identifying key stressors which spouses and children experienced in relation to the sudden deployment, as well a stress mediators such as social supports and personal coping skills. Anecdotal information collected during the site visits, combined with findings from previous research on Army families, was used to develop a questionnaire designed to quantify those variables which emerged as relevant to a study of stressors and stress mediators in the context of the ODS deployment.     

Finding the Locus of Semantic Satiation: An Electrophysiological Attempt

The present study examined the effect of massed repetition of an initial category name upon the subsequent semantic categorization of a target word by means of an electrophysiological measure of semantic processing: the N400. Results showed the classic N400 effect, whereby evoked potentials were more negative for targets that were not members of the repeated category than for member targets. Moreover, repetition of the category name led to an increased and sustained positivity. The N400 effect was not modified, however, by repetition. Hence, insomuch as the N400 reflects meaning integration processes, these results do not support the hypothesis that massed repetition exerts its influence at the level of meaning integration.     

Is it emotion or is it stress? Gender stereotypes and the perception of subjective experience

Two studies of college undergraduates (ns = 95 and 92, primarily non-Hispanic whites and Asian Americans) investigated gender stereotypes of stress and emotion, as well as variables that influence the perception of gender-related differences. Study 1 assessed how gender stereotypes differ from the self-reports of men and women. When asked to choose a label for the subjective experience of the average man and the average woman in a series of problematic hypothetical situations, participants generally tended to believe that the average female would feel ‘emotional,” but that the average male would feel “stressed.” By contrast, the label participants chose to describe their own subjective experience was not significantly affected by their gender. In addition, participants believed the average woman and man differed more in the intensity of their emotions than in the intensity of their stress, a belief contradicted by their own self-reports. Results of Study 2 indicated that gender-related differences in estimations of stress and emotion for the self were reduced or eliminated when specific information about experience-eliciting situations was provided. We would like to thank Matthew Dank for his help in preparing the stimulus materials.     

THE THEOLOGICAL ANTHROPOLOGY OF RALPH WENDELL BURHOE

Abstract. A central aim of Ralph Wendell Burhoe's scientific theology is to define and interpret the meaning of human existence in relation to “ultimate reality.” As such, it can be understood as an exercise in theological anthropology. For Burhoe, this ultimate reality is “nature,” understood as the total reality system which is studied by the sciences and which the sciences are showing to be the sole determiner of the way things are. This article discusses various aspects of Burhoe's theological anthropology, as well as its value and credibility, and raises questions concerning his understanding of the value of the individual and the problems of evil and human sinfulness.     

Traditional vs. nontraditional women and men's perceptions of the personalities and physiques of ideal women and men

Traditional and nontraditional women and men's perceptions of ideal people, in terms of both traits and physiques, were assessed using 80 male and 80 female Caucasian undergraduates as study participants. The data indicated that traditional women and men perceived the ideal male as mesomorphic and as having more instrumental than expressive traits. Nontraditional women and men also favored a mesomorphic physique for the ideal male, but they differed from traditionals in that they saw this mesomorphic male as being androgynous in regard to traits. Concerning the ideal female, traditional and nontraditional women and men preferred an androgynous physique, but they differed in their perceptions of the ideal personality for a woman. Traditional women and men perceived their ideal women as having more expressive than instrumental traits, whereas nontraditional women and men saw their ideal women as being androgynous in regard to traits. The results are discussed within the framework of Bem's gender schema and enculturated lens theories.
