Further experiments on movement masking

Voluntary attention to one of two static objects in the peripheral field of one eye makes this object more liable to masking by a moving object in the corresponding area of the field of the other eye (Experiment 1).

Positive after images (and probably negative after images) are subject to (binocular) movement masking (Experiment 2).

Movement masking can occur in the field of either eye, but with the displays so far tried the inhibitory influence of a moving object is less in the field of the eye to which it is shown than in the field of the other eye (Experiment 3).     

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.     

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.
