Thyroid hormones,psychophysiological reactivity,and anxiety

Thirty-eight adults were assigned to three groups: posttreatment hyperthyroid (n=13), low euthyroid (n=12), and high euthyroid (n=13). Physiological and subjective responses to three anxiety-induction procedures—public speaking, personally distressing imagery, and threat of shock—were compared across groups. Although there were differences across stressors for physiological and subjective measures, group differences were not detected. Results are discussed with regard to the risk for residual anxiety following treatment for hyperthyroidism and the possible influence of thyroid function on the etiology or maintenance of anxiety.     

Teaching ethics in engineering and computer science: A panel discussion

At a conference, two engineering professors and a philosophy professor discussed the teaching of ethics in engineering and computer science. The panelists considered the integration of material on ethics into technical courses, the role of ethical theory in teaching applied ethics, the relationship between cases and codes of ethics, the enlisting of support of engineering faculty, the background needed to teach ethics, and the assessment of student outcomes. Several audience members contributed comments, particularly on teaching ethical theory and on student assessment. This panel discussion took place at a mini-conference, Practicing and Teaching Ethics in Engineering and Computing, held during the Sixth Annual Meeting of the Association for Practical and Professional Ethics, Washington, D.C., March 8–9, 1997. Biographical information on panelists: Charles Glagola is an assistant professor of civil engineering at the University of Florida. He is a registered professional engineer in the states of Florida and Alabama. Before coming to academia, he had extensive industry experience culminating with his owning and operating a construction and engineering firm in Pensacola, Florida. He currently teaches engineering ethics as part of a professional issues course in the Department of Civil Engineering, and a one-hour engineering ethics course that is offered to all engineering students through the College of Engineering. Moshe Kam is professor of electrical and computer engineering at Drexel University. He heads Drexel’s Data Fusion Laboratory which specializes in multisensor systems and robot navigation. His professional interests include detection and estimation, distributed decision making, forensic applications of image processing, and engineering ethics. Michael Loui is professor of electrical and computer engineering and associate dean of the Graduate College at the University of Illinois at Urbana-Champaign. From 1990 to 1991, he served at the National Science Foundation in Washington, D.C. His scholarly interests include computational complexity theory, theory of parallel and distributed computation, fault-tolerant software, and professional ethics. Caroline Whitbeck is a philosopher of science, technology and medicine and is the Elmer G. Beamer-Hubert H. Shneider Professor in Ethics at Case-Western Reserve University. She also directs the WWW Ethics Center for Engineering & Science— http://ethics.cwru.edu— under a grant from the National Science Foundation. The focus of her current work is practical ethics, especially ethics in scholarly and scientific research. Her book, Ethics in Engineering Practice and Research, will appear from Cambridge University Press in winter 1997–98.     

Childhood abuse and spiritual development among women religious

Childhood abuse is known to have a negative influence on human development. This study expected to find a spiritual attitude of acceptance, as measured by the Ego Grasping Orientation scale, would help mitigate effects of childhood abuse in the realm of spiritual development. Spiritual Experience Index (SEI) scores for 350 religious women were treated as a measure of spiritual maturity. Contrary to expectation, however, the sexually and the physically abused groups with a more accepting attitude scored lower on the SEI than the abused with a more controlling attitude and the nonabused. Implications for spiritual development and well-being are discussed.     

PREDICTORS OF RESPONSES TO UNWANTED SEXUAL ATTENTION

Data were collected from 4,011 male and female university students, faculty, and staff regarding responses to unwanted sexual attention. Women and undergraduate students reported the highest incidence of unwanted sexual attention; most harassers were peers. Ignoring the behavior was the most common response, followed by avoiding the harasser and talking to others about the harassment. Harassment severity was the strongest predictor of responses, with more direct responses being made to more severe harassment. Bivariate correlational analyses suggested that unwanted sexual attention was rated as more distressing by women than by men, by faculty/staff than by students, by individuals with less tolerant attitudes toward harassment, and when the harasser was in a position of authority or when the harassment was of longer duration. In path analyses, only the relations between attitudes and responses were mediated by differences in perceived severity. The gender and status (i.e., student vs. faculty/staff) of the harassee, the duration of the harassment, and whether the harasser was in a position of authority had direct effects on responses not attributable to perceived severity. Implications for policy and future research are discussed.     

The role of attention in automatization: Does attention operate at encoding, or retrieval, or both?

In this research, we investigated whether attention operates in the encoding of automatized information, the retrieval of automatized information, or in both cases. Subjects searched two-word displays for members of a target category in focused-attention or divided-attention conditions that were crossed with block (training vs. transfer). To see whether subjects encoded all available items or only attended items, we compared performance for subjects in different training conditions but in the same transfer condition. Subjects encoded attended items. To see whether subjects retrieved all the items they had in memory, or only items associated with that to which they were attending at retrieval, we compared performance for subjects in the same training conditions but in different transfer conditions. Subjects retrieved attended items. Attention was found to operate at both encoding and retrieval. These findings support the instance theory of automaticity, which predicts the role of attention at encoding and retrieval     

Children's understanding of the self-presentational strategies of ingratiation and self-promotion

Eight- and eleven-year-olds' explanations for the self-presentational behaviour of story characters provided clear support for a predicted shift between these ages from understanding in terms of psychological to understanding in terms of interpersonal processes. However, a prediction that the strategy of self-promotion would be better understood than that of ingratiation was not supported.     

On the ability to inhibit simple and choice reaction time responses: a model and a method

This article reports four experiments on the ability to inhibit responses in simple and choice reaction time (RT) tasks. Subjects responding to visually presented letters were occasionally presented with a stop signal (a tone) that told them not to respond on that trial. The major dependent variables were (a) the probability of inhibiting a response when the signal occurred, (b) mean and standard deviation (SD) of RT on no-signal trials, (c) mean RT on trials on which the signal occurred but subjects failed to inhibit, and (d) estimated RT to the stop signal. A model was proposed to estimated RT to the stop signal and to account for the relations among the variables. Its main assumption is that the RT process and the stopping process race, and response inhibition depends on which process finishes first. The model allows us to account for differences in response inhibition between tasks in terms of transformations of stop-signal delay that represent the relative finishing times of the RT process and the stopping process. The transformations specified by the model were successful in group data and in data from individual subjects, regardless of how delays were selected. The experiments also compared different methods of selecting stop-signal delays to equate the probability of inhibition in the two tasks.     

Central integration effects with stabilized afterimages

Prolonged patterned afterimages were used to study integration effects in stabilized images. Seven Ss were presented with various configurations of a pattern through a prism stereoscope, both monocularly and binocularly. Some of the fragmentations and regenerations reported in the binocular condition could only have resulted as a function of organization of the inputs to the two eyes, suggesting that postretinal processes are operative in stabilized image phenomena.     

CORRECTION DES VERBALISATIONS IRRATIONNELLES CHEZ DES JOUEURS DE POKER-VIDEO*

Earlier studies have shown that irrational thinking dominates rational thinking during gambling. The present study evaluated the effects of cognitive restructuring on gambling behaviors among video poker players. Within a single case experimental design across subjects, the results showed that irrational verbalizations decreased during treatment while rational verbalizations increased. Three out of four players reduced their frequency of gambling following treatment. The theoretical and clinical implications of these results are discussed.
