The coordination of compensatory tracking and anticipatory timing tasks

Two experiments investigated the presence of a coordination factor in a task consisting of compensatory tracking and anticipatory timing components. The task (Intercept task) resembles a computer game in which a rocket must be aimed and fired to shoot an incoming missile. The studies were designed to determine if a coordinating ability exists above and beyond the abilities needed to perform the component tasks alone. We also investigated the nature of coordination abilities through correlations with other types of coordination tasks and measures of intelligence. Is coordination a general cognitive ability that contributes to performance in a wide range of coordination tasks, or is coordination ability task specific? Multiple regression analyses indicated the existence of a coordination ability in the Intercept task. This coordination ability, however, was shown to be unrelated to the coordination of visual and linguistic processing and to psychometric measures of intelligence as assessed by the Armed Services Vocational Aptitude Battery (ASVAB). Coordination of visual and linguistic processing correlated with a component of the ASVAB measuring perceptual speed. We conclude that, although the ability to integrate separate components of a complex task draws on a coordination ability, this ability is domain specific and thus varies depending on the nature of the component tasks.     

Death,medicine & bioethics

The assumptions of philosophy need scrutiny as much the assumptions of medicine do. Scrutiny shows that the philosophical method of bioethics is compromised, for it shares certain fundamental assumptions with medicine itself. To show this requires an unorthodox style of philosophy — a literary one. To show the compromised status of bioethics the paper discusses some seminal utilitarian discussions of the definition of death, of whether it is a bad thing, and of when it ought to occur.     

Pastoral care and miscarriage: A ministry long neglected

Ministers often are estranged from the loss experience of women who miscarry. This paper gives medical information about such spontaneous abortions, describes several factors that shape the woman's experience, and explores possible pastoral response.Swanee Hunt is a candidate for Th.D. in pastoral care and counseling at Iliff School of Theology, Denver, Colorado. She is part of an ecumenical ministry team that serves both a Presbyterian church community and a Catholic church community.     

The effect of an increased awareness of erectile cues on sexual arousal

The present investigation addressed two major issues. The first issue is the effect on sexual arousal of increasing a S's self-directed genital focus during different intensities of erotic stimulation. It was found that increasing one's focus on genital cues during low-arousing stimuli decreased physiological arousal, but actually facilitated genital arousal at high-intensity stimulation. This finding brings into question the previous assumption that increased focus on erectile responding or ‘spectatoring’ has universally negative consequences. The second issue concerns the extent of response-system concordance for the physiological and subjective measures of sexual arousal. Two methods of measuring such agreement are proposed. These methods allow for the assessment of response-system concordance for both intensity and direction. These two parameters of concordance were then examined under different levels of arousal and under the two attentiona! focus conditions to ascertain if situational factors would affect response-system agreement. The results indicate that the two measures of concordance are differentially affected by such manipulations. Implications for the measurement of sexual arousal are discussed.     

A systems perspective to marriage counseling

The influence of General Systems Theory on mental health disciplines and pastoral care has grown rapidly in recent years. The central concepts of a systems perspective-organization, control, and stability, and energy-provide an effective means to address organic, relational, and wholistic dimensions of marriage and marriage counselingThis article reflects research for a dissertation/project, including A Guide for Clergy.

Individual differences in the ability to focus and divide attention

This research deals with individual differences in the ability to focus and divide attention. Eighty-five subjects performed visual search and auditory detection tasks in three conditions: single channel, focused attention, and divided attention. Reaction time (RT) was fastest in the single channel condition, intermediate in the focused attention condition, and longest in the divided attention condition, and these effects were much stronger in the auditory than the visual task. Correlations among RTs in the three conditions were very high within modality (>.88), and lower between modalities (.5 to .6). The correlational data was well fit by a model that included separate factors for the visual and auditory tasks. Measures from the three attentional conditions within each modality loaded equally on these factors. The data provided no evidence for distinct abilities to divide or focus attention.     

Individual differences in long-term memory access

In a study of individual differences in long-term memory access, university undergraduates verified (1) whether an item was a member of a category, (2) whether two items belonged to the same category, and (3) whether two words had the same name. Reaction times from these tasks were correlated with verbal ability, as measured by performance on a standardized test of vocabulary and reading comprehension. A relationship was found between verbal ability and reaction time in the verification tasks. These results are contrasted with those of Hogaboam and Pellegrino (1978), who failed to find such a relationship. The results indicated that the various reaction time measures form a single factor that bears a moderate relationship to reading and vocabulary measures.     

The process-observer in group therapy

This case study describes the inclusion of a nonverbal, trained process-observer into therapy groups for parents having severely disturbed family systems. The observer remained nonverbal during the sessions while taking notes to be used in writing a one-page clinical summary, which was mailed to each group member. The process-observer was included to improve the clients' initial involvement in dealing with personal problems and as a catalyst for group development. Among the important functions of the written summaries were: reduction of initial anxiety, focusing the group on important issues, enhancement of continuity across sessions, and promoting therapeutic work between sessions. The observer was also valuable in providing feedback to the therapists. Specific guidelines for the use of a process-observer are provided.
