Visual form perception 6041 words
Peter U. Tse and Howard C. Hughes In the absence of any apparent effort, the human visual system recovers the 3 dimensional form of the visible environment from inherently ambiguous 2 dimensional retinal images. How this feat is accomplished is perhaps the most fundamental problem faced by vision science. Despite the impression that vision seems effortless, a vast amount of processing is involv...
متن کاملLocal form-motion interactions influence global form perception.
Object motion perception depends on the integration of form and motion information into a unified neural representation. Historically, form and motion perception are thought to be independent processes; however, research has demonstrated that these processes interact in numerous and complex ways. For example, an object's orientation relative to its direction of motion will influence its perceiv...
متن کاملPerception of Motion , Depth , and Form
IN VISION, AS IN OTHER mental operations, we experience the world as a whole. Independent attributes—motion, depth, form, and color—are coordinated into a single visual image. In the two previous chapters we began to consider how two parallel pathways—the magnocellular and parvocellular pathways, that extend from the retina through the lateral geniculate nucleus of the thalamus to the primary v...
متن کاملPerception and action in 'visual form agnosia'.
A single case study of a patient with 'visual form agnosia' is presented. A severe visual recognition deficit was accompanied by impairments in discriminating shape, reflectance, and orientation, although visual acuity and colour vision, along with tactile recognition and intelligence, were largely preserved. Neuropsychological and behavioural investigations have indicated that the patient is a...
متن کاملLocal form interference in biological motion perception
Replacing the local dots of point-light walkers with complex images leads to significant detriments to performance in biological motion detection and discrimination tasks. This detriment has previously been shown to be larger when the local elements match the global shape in object category and facing direction. In contrast, studies using Navon stimuli have demonstrated that local interference ...
