Integration Of Speed Signals In The Direction Of Motion, Dawn Vreven, Preeti Verghese

Dawn L Vreven

Speed discrimination tasks were used to examine the spatial and temporal characteristics of the integration mechanism involved when signals are extended in the direction of motion. We varied the aspect ratio of a signal patch whose speed differed from the background, while holding the area of the signal patch constant, so that the signal patch could be either extended in the direction of motion or extended orthogonal to the direction of motion. Speed discrimination thresholds decreased dramatically as the signal patch was extended in the direction of motion. The spatial and temporal integration regions were larger than would be expected …

Detecting Structure In Glass Patterns: An Interocular Transfer Study, Dawn Vreven, Jarrod Berge

Dawn L Vreven

Glass patterns are visual stimuli used here to study how local orientation signals are spatially integrated into global pattern perception. We measured a form aftereffect from adaptation to both static and dynamic Glass patterns and calculated the amount of interocular transfer to determine the binocularity of the detectors responsible for the perception of global structure. Both static and dynamic adaptation produced significant form aftereffects and showed a very high degree of interocular transfer, suggesting that Glass-pattern perception involves cortical processing beyond primary visual cortex. Surprisingly, dynamic adaptation produced significantly greater interocular transfer than static adaptation. Our results suggest a functional …

Undergraduate Psychology Training And Workplace Needs: Student Perspectives On The Extent To Which Their Education Prepares Them For Their Chosen Career, G Stoyles, P Caputi, M Byrne, T Crowe

Mitchell K Byrne

The current study surveyed 195 first to fourth year psychology students at a regional university in New South Wales about the amount of applied content in undergraduate psychology training and post-graduate opportunities for employment as a psychologist. Eighty-nine percent of students believed that the level of applied psychological training was either nonexistent or inadequate, and therefore did not equip them for finding work as a psychologist. Ninety-six percent of students who wished to become intern psychologists believed that opportunities for working as intern generalist psychologists were either non-existent or insufficient. Concerns around employment and registration opportunities reflected this group’s disillusionment …

Dynamics Of Drug Use, Joan Rollins, Raymond Holden

Joan H Rollins

This paper analyzes data from interviews with167 drug users in the community, including age, sex, birth order, education, family constellation, age of first drug use and circumstances of first drug use. Initial drug use was usually a social experience, with considerable influence from peers. Usually initial drug use began with marijuana or alcohol. The majority of subjects had tried to stop using drugs, but most of them had been unsuccessful at the time of the interview.
