The Effectiveness of Career Development Seminars on African American Premedical Students: A Program Evaluation Using the Medical Career Development Inventory

The authors examined the impact of a structured career planning program on the career maturity scores of 61 African American premedical students as measured by the Medical Career Development Inventory.     

Perceptual enhancement of tumor targets in chest X-ray images

Under tachistoscopic viewing conditions, precuing the location of potential lung tumorlargets in chest X-ray images was less effective than precuing followed by bounding the region of interest (ROI) with a circle directly on the image. Detection performance increased as the image was systematically masked so that its size approximated that of the circled ROI. When viewing time was extended to allow shifts in eye position, circling the ROI was found to restrict the dispersion of fixations and increase the accuracy of fixating the target tumor. When targets were placed outside the ROI, the circle inhibited their detection relative to detection of targets inside the circled region. These findings suggest that cuing by circling restricts target detection to the ROI, and by doing so reduces the interfering effects of outside distractors that compete with the target for attention.

Experiential Group Psychotherapy Supervision

Following a review of various traditional models of supervising group therapy, an experiential model of supervising group in a group setting is presented. The model stresses the group aspect of the supervisory process, encourages group interaction, here-and-now responses and associations, and employs concepts from both object relations and group-as-a-whole theory to understand what is taking place. The model's premise is that case material presented in a supervision group stimulates parallel material in supervisees, which is then used to elucidate what has taken place in the therapy group being presented. Excerpts from one supervisory group are used to illustrate major features of the model.     

MARITAL SATISFACTION AND DEPRESSION:

Abstract— A sample of 150 recently married couples provided data egarding marital satisfaction and depressive symptoms. Approximately 18 months later, 116 of these couples provided complete information on marital satisfaction and depression once again. The data were examined using three sets of causal models, which yielded converging results. For men, causal paths emerged from depression to marital satisfaction, whereas for women causal paths were from satisfaction to depression. The results are discussed in relation to the marital discord model of depression.     

Simulating naturalistic demands for speeded judgment

Responses to speeded judgment (e.g., “shoot/don’t shoot”) situations in naturalistic environments are influenced by many variables and psychological processes. We describe a custom-built simulator with head- and eye-tracking capabilities for basic and applied research on speeded decision making. The system allows the user to project life-sized, time-coded, videotaped, or computer-animated scenarios on a screen to collect reaction-time, shot-accuracy, and eye-movement data. An initial experiment is also reported to demonstrate the utility of the system for studying factors that affect speeded judgment under naturalistic situations.     

Voice reaction time of stuttering and nonstuttering children and adults

The voice reaction time (VRT) of 5-yr old, 9-yr old, and adult stutterers and nonstutterers was investigated. Subjects initiated the sound / Λ / in response to fifty-five 1000-Hz tones of 1 sec duration. The tones were presented in five equal sets of 11 tones each with the silent intervals between the tones randomly selected to be 3, 4, 5, or 6 sec. Data analysis was based on responses 2–11 for each set. The VRTs for both the stutterers and the nonstutterers decreased significantly as an inverse function of age, with the largest decrease in reaction time occuring between 5 and 9 yr. The VRTs for the stutterers, however, were significantly slower than those of the nonstutterers at each of the three age levels. The results suggest that observed disruption in the laryngeal behavior for at least some stutterers may not result from the development of stuttering with age, but may contribute to early difficulty in the child's ability to produce fluent speech. Consideration of central factors are discussed.     

Time for auditory processing of object names by aphasics

Ten Wernicke's and ten Broca's aphasics were compared with normal controls and brain-damaged nonaphasics with respect to the time required for the auditory decoding of object names. This value was obtained by using a subtraction method with two reaction time determinations, one of which included an auditory processing phase while the other did not. The overall mean of approximately 200 msec for Broca's aphasics did not differ significantly from the normal, while the mean of 650 msec for the Wernicke aphasics was much slower. All groups responded more quickly to high-frequency than low-frequency words and all but the Wernicke aphasics improved in the second trial block over their performance in the first trial block.
