THE ROLE OF THE CAT’S ANTERIOR ECTOSYLVIAN CORTEX IN
… sulcus (AES) of the cat cortex are critical for orientation to multisensory stimuli. However, whether AES also plays a role in orientation to unisensory auditory stimuli is not yet clear. Some studies have shown that AES deactivation does not produce unisensory (visual or auditory) orientation …

Biology and host finding of predaceous hister beetles (Coleoptera: Histeridae) associated with Ips spp. (Coleoptera: Scolytidae) in loblolly pine (Pinus taeda L.)
… arriving later in the colonization sequence. Visual orientation appeared to affect host tree location by histerids and may facilitate niche partitioning among species. Platysoma parallelum was attracted to horizontally positioned logs, representing trees more likely to be infested by Ips spp., …

Roles of reward, memory, and cognitive control on visual perceptual learning and decision-making
A prevailing hypothesis of visual perceptual learning (VPL) is that for a feature to be learned, focused attention must be directed to that feature. Along these lines, top-down, task-related factors are also required for such learning to take place. The first aim of this thesis was to challenge …

Ecology of fall-migrating ducks in central Illinois: a radar perspective
… that ducks rely on leading-lines of rivers for visual orientation during flight is a dominant paradigm in waterfowl science. I examined departure tracks of emigration events from my study site during 1995–2009 and found ducks had a significant SSE directional preference (152°; P < 0.05), which …

The development and plasticity of visuo-spatial orienting behaviors and underlying circuitry in adolescent mice
Sex differences in visual processing during behavior exist across a wide variety of species, from flies to humans. However, it remains unclear whether sexual dimorphism in natural visual behavior exists for standard laboratory strains of mice, a prominent model for understanding the neural basis of …

Cognitive flexibility training with severely and moderately mentally handicapped persons
… children, find difficulty in discriminating visual orientation and rotated mirror-images. In the third experiment the effects of perceptual training are evaluated in geometrical figures and their reversals. The results are significant to indicate, once again, that overt responses of severely …
