Psychology at the University of Deseret (Utah)
The University of Deseret (now the University of Utah) was organized in 1850. Mental philosophy appeared in the curriculum in 1868, and psychology, by that title, in 1893; but the designation of a department and the hiring of a faculty trained specifically in psychology did not occur until 1911 with the arrival of Joseph Peterson. Up to World War II, faculty and students were few, and psychology courses were aimed at the training of teachers. Aft…

Heart-Rate Response during Aversive Conditioning
36 rats were used to determine the effects of: (a) footshock before specific training, (b) CS duration (6 vs 60 sec.), and (c) form of aversive conditioning (CER vs CAR) on heart rate both during the presentation of the CS and between presentations. All three tested variables were effective in modifying the heart-rate response to the CS while only CS duration altered heart rates between CS presentations
Modification of the Autonomic Component of the Conditioned Emotional Response
A series of experiments was conducted to clarify the role of the autonomic nervous system in the acquisition and maintenance of the conditioned emotional response (CER). In Exp. 1 the reactivity of either the sympathetic or the parasympathetic system was altered by drugs during maintenance testing of the CER. 12 rats were trained to bar-press for sugar water on a VI 30-sec. schedule; 6 CER trials were administered during each 2-hr. session. The i…
Faculty Evaluations of Graduate Students
EEG indexes, ratings of research potential, and ratings of research attainment 10 years later, were obtained for 30 graduate students. Ratings of potential correlated .50 with attainment of the Ph.D. and .58 with ratings of subsequent research attainment. EEG indexes were unrelated to either set of ratings
Effects of Differential Rearing and Levels of Motivation
6 male littermate rats reared from weaning in environments of either reduced or augmented stimulus variety were compared under different conditions of motivational urgency. Tests involving high urgency—initial exposure to an open field, passive (step-down) avoidance of foot-shock, and CER acquisition—showed no differences ( ps > .05). The test involving low urgency —extinction of the CER—separated the groups ( p < .01)
Effects of Anticonvulsant Drugs upon Patterns of Seizure Discharge and Brain Thresholds
10 cats were trained to perform an avoidance leg flexion at a signal: electrical stimulation of the caudate nucleus or the centre median. Thresholds were found to be elevated by anticonvulsants. In 3 of these cats, seizure discharges were induced by stimulation of the hippocampus and recorded on an EEG. The data are interpreted as indicating alteration of nerve impulse pathways. It is argued that such alteration may underlie dissociation of learn…
Isolated Rearing and Hebb-Williams Maze Performance
48 male hooded rats were reared from weaning to adulthood either individually in small opaque-walled cages or together in larger, open cages containing various objects. Following rearing, Ss' “emotionality” and their efficiency at solving maze problems were measured. Consonant with other studies, Ss reared in isolation were more “emotional.” Unlike previous reports, Ss of the isolated rearing condition were as efficient at solving maze problems a…
Delayed Punishment of Positively Reinforced Bar Presses
Combining positive and negative reinforcement (both being electrical stimulation of the brain) for lever pressing by 4 rats produced a gradient of suppression as the 2 qualities of reinforcement were separated temporally. Maximal suppression occurred with an interstimulus interval of about 1 sec. This maximum was interpreted as marking the intersection of a waning interaction of the neurological aspects of reward and punishment and a delay-of-pun…
Effects of Restricted Rearing on Lashley Stand Performance
Rats were reared from weaning to adulthood in either an isolated or enriched environment. Their efficiency at solving a visual discrimination on the Lashley jumping stand and their emotionality were measured as adults. Differences in efficiency of discrimination were slight. Isolated Ss were more timid during the early phases of the experiment but this timidity was reduced by the end of training
Electrical Intracranial Stimulation as a Primary Reinforcer for Cats
Cats were trained to press a bar to receive electrical stimulation in the region of the medial forebrain bundle. The training was achieved without the employment of prior training to any conventional reinforcer but required a very large number of stimulations before the cats began to show positive reinforcement from the stimulations. It appears that the cats' response to intracranial stimulation underwent a transition from negative to positive wi…
Overnight Performance Decrement with Intracranial Reinforcement
An overnight performance decrement is allegedly characteristic of habits maintained by intracranial electrical stimulation. The decrement was here found to be (a) not common to all electrode sites, (b) reduced by one un-reinforced trial, and (c) reduced by intracranial stimulation administered below a rewarding intensity. The electrode sites not associated with performance decrement were in the median forebrain bundle (MFB). Those associated with…
