Laterality Enhances Cognition In Australian Parrots, Maria Magat, Culum Brown Dec 2009

Laterality Enhances Cognition In Australian Parrots, Maria Magat, Culum Brown

Sentience Collection

Cerebral lateralization refers to the division of information processing in either hemisphere of the brain and is a ubiquitous trait among vertebrates and invertebrates. Given its widespread occurrence, it is likely that cerebral lateralization confers a fitness advantage. It has been hypothesized that this advantage takes the form of enhanced cognitive function, potentially via a dual processing mechanism whereby each hemisphere can be used to process specific types of information without contralateral interference. Here, we examined the influence of lateralization on problem solving by Australian parrots. The first task, a pebble-seed discrimination test, was designed for small parrot species that …

Building on our strengths: a framework to reduce race-based discrimination and support diversity in Victoria has been developed through a partnership between the Victorian Health Promotion Foundation (VicHealth), the Victorian Equal Opportunity and Human Rights Commission, the McCaughey Centre: VicHealth Centre for the Promotion of Mental Health and Community Wellbeing and the Onemda VicHealth Koori Health Unit. The McCaughey Centre and Onemda are both in the School of Population Health at the University of Melbourne.

Drawing on the best available evidence in Australia and internationally, this report outlines themes, strategies and priority settings for the development and implementation of activity …

Stereoscopic Discrimination Of The Layout Of Ground Surfaces, Robert S. Allison, Barbara J. Gillam, Stephen A. Palmisano

Safe and effective locomotion depends critically on judgements of the surface properties of the ground to be traversed. Little is known about the role of binocular vision in surface perception at distances relevant to visually guided locomotion in humans. Programmable arrays of illuminated targets were used to present sparsely textured surfaces with real depth at distances of 4.5 and 9.0 m. Psychophysical measurements of discrimination thresholds demonstrated a clear superiority for stereoscopic over monocular judgments of relative and absolute surface slant. Judgements of surface roughness in particular demonstrated a substantial binocular advantage. Binocular vision is thus shown to directly contribute …
