Available in PDF, EPUB and Kindle. Book excerpt: This volume was designed to focus on the problems of perception and originally was to have been solely edited by Professor Hans-Lukas Teuber who was a member of the editorial board which initiated production of the Handbook. Accordingly, he issued invitations to a number of researchers III perception asking them to contribute chapters written in a style described III his words: " . . . Ire hope that no author lI'ill feel COl/strained to undertake a major search of the literature: he could In'ite, instead. on an area in which he has been quite actire himse?t~ and II'here most of the issues are immediately obt"ious to him. In this Iray, the IITiting of the chapter should be cnjoyable rather than a chore . . it should result in a personal account of the state of a given area rather than in an encyclopedic treatise . . . the field deserves this sort of summary ret'iell", particularly (f it is pointed toward the future and speeds the convergence of det'elopments in sensory physiology and psychological studies of perception, " With the growing burden of national and international commitments includ ing departmental headship, Professor Teuber felt that it would be wise to share the editorial responsibilities for this volume and accordingly, asked Professors Richard Held and Herschel Leibowitz to co-edit the volume with him in the same spirit as outlined in his invitation to authors. They agreed to help in this task.

Available in PDF, EPUB and Kindle. Book excerpt: The following studies examined age-related decrements in motion perception processing. Using a perceptual learning paradigm, perceptual inefficiency was compared between younger and older observers. Perceptual inefficiency was modeled using the Perceptual Template Model (Lu & Dosher, 1998; Lu & Dosher, 1999). Baseline differences and changes over training were assessed for additive internal noise, tolerance to external noise, and internal multiplicative noise in both older and younger observers. Experiments 1 and 2 examined age-related changes in baseline perceptual inefficiency and learning after training. Experiments 1 and 2 trained participants by manipulating contrast in noise embedded sine-wave gratings and Random Dot Cinematograms (RDCs). The results indicate that older observers have higher additive internal noise and lower tolerance to external noise compared to younger observers. Perceptual learning in older observers was found to be at a similar rate to that of younger observers suggesting that cortical plasticity for motion processing is well preserved in advancing age. Experiment 3 examined transfer of learning between sine-wave gratings and RDCs for both older and younger observers. The results indicated that transfer of learning occurred for both age groups. This suggests that older individuals maintain a sufficient degree of plasticity to allow generalization between sine-wave gratings and RDCs. In addition, training with RDCs was found to produce greater perceptual learning than training with sine-wave gratings. Experiment 4 examined if center-surround antagonism could be increased through perceptual training which would provide evidence that neural inhibition is related to internal noise. Center-surround antagonism enables edge detection through an antagonistic interaction between the center and the surround regions of a receptive field. Younger and older participants were trained on duration thresholds with Gabor patches that varied in size and contrast. The results of Experiment 4 indicate that some perceptual learning occurred in both younger and older participants but were inconclusive with regards to inhibition in visual cortex. The present studies provided important findings regarding changes in perceptual efficiency for motion perception in older adults. Cortical plasticity was found to be well preserved in older adults indicating that perceptual training may be an effective way to improve motion perception.

Download or read book Perception Through Experience written by M.D. Vernon and published by Routledge. This book was released on 2017-03-27 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term ‘visual perception’ covers a very wide range of psychological functions. This title, originally published in 1970, which provides a broad survey of this vast field of knowledge, would have proved a valuable general account for students taking degree courses in psychology at the time. Professor Vernon examines a large number of experiments carried out over the previous twenty years, their findings, the conclusions drawn from them, and – equally important – the still unanswered questions which some of them raised. As the title suggests, Professor Vernon considers that – while much knowledge of the simpler perceptual processes had been gained in laboratory experiments – perhaps too little investigation had been undertaken into the more complex processes which normally determine understanding of and response to environment: the processes of identification and classification that depend to a considerable extent on learning, memory, attention, reasoning and language. An extensive bibliography is provided.

Available in PDF, EPUB and Kindle. Book excerpt: To derive the precise estimates of self-motion necessary to perform mobility-related tasks like walking and driving, humans integrate information about their movement from across their sensory systems (e.g. visual, auditory, proprioceptive, vestibular). However, recent evidence suggests that the way in which multiple sensory inputs are integrated by the adult brain changes with age. The objective of this thesis was to consider, for the first time, whether age-related changes in multisensory integration are observed in the context of self-motion perception. Two research approaches were used. First, I used a simple, simulated driving task to provide visual cues to self-motion and to manipulate the availability of auditory and/or vestibular cues to self-motion (i.e., unisensory versus multisensory conditions). The results revealed that relative to younger adults, older adults generally demonstrate greater differences in performance between multisensory and unisensory conditions. However, the driving task could not disentangle the effects of age-related differences in real-world driving experience from age-related differences in sensory integrative mechanisms. Second, I used an established and highly controlled psychophysical heading perception task to evaluate whether, like younger adults, older adults integrate visual and vestibular cues to self-motion in a statistically optimal fashion. I considered conditions where each of the two cues was presented alone, in combination and congruent, or in combination but indicating conflicting heading angles. Results showed that while older adults did demonstrate optimal integration during congruent conditions, they were comparatively less tolerant to spatial conflicts between the visual and vestibular inputs. Overall, these results may have important implications for the way that older adults perform mobility-related tasks under various perceptual and environmental conditions.

Book excerpt: The first English translation of a classic work in vision science from 1936 by a leading figure in the Gestalt movement, covering topics that continue to be major issues in vision research today. This classic work in vision science, written by a leading figure in Germany's Gestalt movement in psychology and first published in 1936, addresses topics that remain of major interest to vision researchers today. Wolfgang Metzger's main argument, drawn from Gestalt theory, is that the objects we perceive in visual experience are not the objects themselves but perceptual effigies of those objects constructed by our brain according to natural rules. Gestalt concepts are currently being increasingly integrated into mainstream neuroscience by researchers proposing network processing beyond the classical receptive field. Metzger's discussion of such topics as ambiguous figures, hidden forms, camouflage, shadows and depth, and three-dimensional representations in paintings will interest anyone working in the field of vision and perception, including psychologists, biologists, neurophysiologists, and researchers in computational vision—and artists, designers, and philosophers. Each chapter is accompanied by compelling visual demonstrations of the phenomena described; the book includes 194 illustrations, drawn from visual science, art, and everyday experience, that invite readers to verify Metzger's observations for themselves. Today's researchers may find themselves pondering the intriguing question of what effect Metzger's theories might have had on vision research if Laws of Seeing and its treasure trove of perceptual observations had been available to the English-speaking world at the time of its writing.
