Memory for the pitch of a tone

Observers attempted to detect the presence of a pitch difference between two successive tones. The percentage of correct judgments was equivalent for tones separated by .95, 4.5, and 8.9 sec. There was a general increase in reports of a pitch difference with increased intertone interval, which is interpreted as arising from hypothesized shifts in the neural locus of the first stimulus during the intertone interval.     

Visual and acoustic confusability a visual search task

Visual and acoustic confusability between a target item and background items was varied in a visual search task. Visual confusability was a highly significant source of difficulty while acoustic confusability had no effect. The results do not seem to be interpretable within a theory which assumes compulsory auditory encoding of visual information.     

Oculomotor adaptation to wedge prisms with no part of the body seen

When S looks at a visual target through prisms, adaptive shifts in reaching behavior occur even though he sees no part of his body through the prisms. These shifts are caused by a change in the judgment of the direction of gaze (oculomotor change), which in turn is caused by two secondary prismatic effects: (a) asymmetry of the visual display and (b) apparent rotation about a vertical axis of a panel or wall facing S. The “asymmetry” factor contributes 22% of the total oculomotor change, and the “rotation” effect contributes the remaining 78%. Oculomotor change is not facilitated by eye-movzment activity. The adaptive oculomotor change induces a non-adaptive proprioception change about one-tenth as large as the oculomotor change. These findings are capable of accounting for the previously unexplained results reported by Wooster in 1923, and also for the current controversy about the role of reafferent stimulation in sensorymotor adaptation.     

Stimulus correlates of visual pattern discrimination by monkeys: Multidimensional analyses

Fourteen monkeys were presented with a series of simultaneous discrimination problems, each problem consisting of two visual metric patterns, and Ss’ performance was analyzed with respect to several physical dimensions of the patterns. Proficiency of discriminative performance was found to be directly and almost exclusively related to the extent to which the two patterns, when translated, had unique parts.     

Clinical pastoral training in an emergency psychiatric service

Summary This paper reports the utilization of an emergency psychiatric service as a new factor in the clinical pastoral training experience. The usual pattern of clinical setting for these students is the hospital ward, where the patient has already been admitted and is making some adjustment to hospital routine and treatment. In such a setting the student misses the opportunity to see the patient at the crisis point of the illness and does not see the large numbers of individuals troubled enough to require psychiatric help but not sick enough to be hospitalized. The latter group constitute the largest portion seen by the parish minister even before psychiatric referral is arranged. During a twelve-week clinical pastoral training program, each student spent a major portion of his time for two of the weeks working on an emergency psychiatric service with a psychiatrist and social worker and seeing a large variety of patients, most of whom were not hospitalized. The experience provided an opportunity to develop evaluative skills and knowledge of appropriate community resources, and offered some experience in brief counseling under supervision. The clinical pastoral training student and the personnel of the emergency service all felt that this was an experience of mutual value and that it should be for a longer period. It is suggested that other clinical pastoral training programs would find it of value to utilize emergency psychiatric clinic settings where available.
