Factor analysis of the interpersonal trust scale with a noncollege population

This study tested the invariance of the factorial structure of Rotter's Interpersonal Trust Scale (ITS) in a noncollege population. Exploratory factor analysis of the responses of 214 volunteers yielded three factors interpreted as Exploitation, Sincerity, and Institutional Trust. This factor solution was cross-validated in a confirmation sample of 196 volunteers. Cosines between corresponding factors were high across samples and across sex. The similarity was pointed out between the present factor structure and the results of earlier studies with college students. Implications for possible refinement of the ITS were discussed.     

The importance of inhalation volume when measuring smoking behavior

Theoretical and technical considerations of measuring puff and inhalation volumes during cigarette smoking are reviewed. Measures of smoking behavior using a flowmeter and inductance plethysmography are described and demonstrated with seven subjects smoking over a 3-to 4-h period. Puff volume and duration, inhaled volume and duration, interpuff and intercigarette interval, and number of puffs varied for each individual over the session. The ratio of puff volume to inhaled volume changed with successive cigarettes. Smokers adjust the concentration of smoke by blending air with the smoke. Thus, to completely characterize smoking behavior, the volume of smoke and air inhaled into the lungs must be measured directly.     

The effects of attentional focus and partner arousal on sexual responding in functional and dysfunctional men

The effects of attentional-focus instructions (self vs partner focus) and level of partner arousal (high, low and ambiguous) on sexual responding, both objectively and subjectively measured, were examined with sexually-functional (N = 8) and sexually-dysfunctional (N = 8) men. These instructional sets were delivered just before the subjects viewed an erotic film depicting a heterosexual couple in which they identified with the male. When both groups were focusing on themselves rather than their partner, higher tumescence was observed when their partner was displaying low arousal. When the partner's level of arousal was ambiguous, highest tumescence was achieved during partner attentional focus. When the partner was displaying high sexual arousal, functional subjects reached highest levels of tumescence during partner focus, while dysfunctional subjects reached highest levels of tumescence during self focus. In fact, high partner arousal seemed to inhibit dysfunctional subjects' tumescence under partner focus. Examination of self-report of arousal data as measured by a subjective lever revealed interesting group differences. Results are discussed in light of possible maintaining factors in sexual dysfunction and their treatment implications.     

Coordinating cognitive information: task effects and individual differences in integrating information from several sources.

In many tasks people have to coordinate the information from several sources. An example would be driving a car while listening to directions. The driver has to establish a correspondence between a visual picture and verbal instructions. This paper addresses two questions concerning information coordination. Is there an ability to coordinate information received from several sources that is different from the ability to deal with information from each source, alone? Does coordination simply involve allocating resources to deal with the component tasks, or does the act of coordination itself constitute a separate task? Four experiments examined the coordination of a verbal component task with a visual-spatial and with an auditory component task. The results showed that the ability to coordinate perceptual and verbal information is separate from the ability to deal with either perceptual or verbal information, alone. A simple resource sharing model was not adequate in explaining how coordination occurred. We relate our results to a model in which perceptual reasoning occurs independently of verbal processing, but transforming perceptual information into a propositional form is affected by concurrent verbal processing.     

Coping with health threat: social influence processes in reactions to medical test results

In a laboratory experiment, undergraduate subjects tested positive for an enzyme deficiency they believed to be a risk factor for pancreatic disorders. All Ss were tested with a confederate who received a positive or negative test result. For half the Ss, the confederate expressed a minimizing appraisal of the deficiency's seriousness. Although Ss' concern about the test result was significantly reduced by what the confederate said, behavioral intentions were determined by the confederate's diagnostic status. The effect of the confederate's diagnostic status on intentions was mediated by Ss' perceptions of the deficiency's prevalence. The results support Leventhal's self-regulation theory and demonstrate that the opinions and health characteristics of comparison others have differential effects on cognitive, emotional, and behavioral aspects of coping with a health threat.     

Developmental and family milieu correlates of resilience in urban children who have experienced major life stress

Reports findings from interviews with parents of demographically-comparable groups of highly-stressed urban children with stress-resilient (SR) and stress-affected (SA) outcomes at ages 10-12. SR and SA children were compared on family milieu and child development variables assessed within a developmental framework. Compared to SAs, parents of SRs scored higher on variables reflecting parent perceptions of a nurturant caregiver-child relationship and self-views as effective caregivers, in the context of positive discipline practices, a child's positive early temperament, and support for primary caregivers. A discriminant function analysis identified seven variables that optimally differentiated the groups and correctly classified 86% of the Ss as SR or SA.     

Persistence in seminary and in ministry

A follow-up study of 672 seminary students from 14 seminaries who took the Theological School Inventory in 1962 and 574 from 10 seminaries who took it in 1973 investigated factors involved in persistence in seminary and in ministry. Among those found were definiteness of decision, interest in parish ministry, a supportive spouse, unambivalent resolution of the authority problem, good role models in father and ministers. Motivations included redemptive outreach, pastoral care, Christian insight and scholarship, the encouragement of other people and a sense of effectiveness in ministry.Dr. Cardwell is Assistant Professor of Psychology and Counseling at Christian Theological Seminary, 1000 W. 42nd St., Indianapolis, Indiana 46208. This study was the basis for her Ph.D. dissertation, Indiana University, June, 1978. TSI data for the 1973 subjects were made available by Richard A. Hunt, Ph.D., Professor of Psychology, Southern Methodist University, and Director of Ministry Inventories, P.O. Box 8265, Dallas, Texas 75205. TSI data for the 1962 subjects were coded and made available by Edgar W. Mills. Ph.D., presently visiting Associate Professor of Sociology, University of Texas, San Antonio, formerly Director, Ministry Studies Board. Special credit is due the 16 seminaries who cooperated by furnishing follow-up data.     

Measurement of head movement during auditory localization

Head movement can have a significant effect on the ability to locate the direction of a sound source. A system has been designed to track the head movement in response to sound originating at different azimuth locations with respect to the head. A videotape record is made of a light approximating a point source carried on a lightweight “beanie” mounted on the listener’s head. Movement of the light is monitored by the video camera and recorded on tape, along with the sound stimulus and information concerning loudspeaker location and time. The horizontal and vertical coordinates of the light-spot image are determined in relation to the video synch pulses defining the field borders. Synch signals are available from a video monitor either in real-time or from tape replay to define each TV frame and horizontal scan line. The circuitry interfaces to a computer programmed to take the information, apply a calibration, and process the data into records of time-varying head position and velocity. Examples of both digital and graphic printouts of head movement are given. The system is capable of expansion to three-axis operation.
