An image-computable psychophysical spatial vision model.
A large part of classical visual psychophysics was concerned with the fundamental question of how pattern information is initially encoded in the human visual system. From these studies a relatively standard model of early spatial vision emerged, based on spatial frequency and orientation-specific channels followed by an accelerating nonlinearity and divisive normalization: contrast gain-contro...
متن کاملProcedural Factors That Affect Psychophysical Measures of Spatial Selectivity in Cochlear Implant Users
Behavioral measures of spatial selectivity in cochlear implants are important both for guiding the programing of individual users' implants and for the evaluation of different stimulation methods. However, the methods used are subject to a number of confounding factors that can contaminate estimates of spatial selectivity. These factors include off-site listening, charge interactions between ma...
متن کاملGeneral overview of spatial impression, envelopment, localization, and externalization
This paper will provide an overview of the current knowledge on the problems of spatial impression, envelopment, and localization in enclosed spaces. The emphasis will be on small spaces, but the approach draws heavily on concert acoustic studies. The literature on this subject has been contradictory and controversial. In the last few years a consensus has been developing that envelopment is pr...
متن کاملAuditory Versus Visual Spatial Impression: A Study of Two Auditoria
Spatial impression refers to the attributes of subjective space beyond localization. In the field of auditorium acoustics, auditory spatial impression is often divided into ‘apparent source width’, ‘envelopment’ and sometimes ‘intimacy’. In separate experiments, this study considers how visual and auditory spatial impression vary within two auditoria, and hence similarities between these two se...
متن کاملThe psychophysical power law and unilateral spatial neglect.
The relationship between objective measures and subjective experiences of sensory stimuli is described by a power law, psi = K phi beta, in which psi represents the psychological value and phi the physical value. The constant (K) and the exponent (beta) are empirically derived. This relationship is often assumed to correspond to properties of peripheral receptor sensory transduction. Patients w...
