The Effects Of Alcohol On Different Classes Of Motion Perception, Steven J. Matson
The Effects Of Alcohol On Different Classes Of Motion Perception, Steven J. Matson
Electronic Thesis and Dissertation Repository
We used a psychophysical approach to investigate how alcohol affected visual sensitivity to perceive different classes of motion. Visual sensitivities were measured in both a non-alcohol and an alcohol condition for three classes of motion: Minimum Motion, Simple Motion, and Complex Motion. Perceptual thresholds, taken as the degree of motion at which an observer responded correctly with an accuracy of 75%, or Weber fractions were compared between the non-alcohol and the alcohol conditions. For Simple and Complex motion, similar comparisons were made as a function of speed (e.g., 2°s-1, 6°s-1, and 12°s-1). Perceptual thresholds …
Towards An Improved Understanding Of The Heterogeneity Of Violence: A Test Of The Clinical Utility Of The Reactive-Instrumental Distinction Among Adult Male Inmates, Jennifer L. Tapscott

Purpose: Interpersonal violence exacts a high cost on society, both in terms of its impact on victims and its associated financial burden. To better understand the heterogeneity of violence, forensic researchers often distinguish between reactive violence, which occurs in response to provocation, and instrumental violence, which is goal-oriented. Although these subtypes of aggression have been associated with unique psychosocial vulnerabilities in samples of children or community adults, the current study examined whether this pattern of divergence generalized to an adult correctional sample. Method: Participants were 151 adult male federal inmates. Inmates completed self-report measures of childhood maltreatment, social-cognitive processing, and …
