Interactions between contrast and spatial displacement in visual motion processing
but, as with Côte d'Ivoire, estimates of chimpanzee abundance are based on survey data collected more than a decade ago [5]. There is an urgent need to locate the remaining viable chimpanzee populations and implement long-term monitoring activities for their conservation. The IUCN/SSC A.P.E.S. (Ape Populations, Environments and Surveys) database (http://apes.eva. mpg.de) seeks to centralize all...
متن کاملAdaptive processing of visual motion.
Three studies relating perception of motion to stimulus uncertainty are reported. Generally, detectability declines when the observer is uncertain about the direction in which a target will move, but the visibility loss associated with direction uncertainty can be attenuated if the observer has adequate practice. This attenuation seems to depend upon the observer's ability to switch among direc...
متن کاملVisual processing of motion boundaries
Psychometric functions for motion detection were measured for various spatial velocity profiles made of independently moving lines of random dots. In the first experiment, sensitivity was greater for square-wave velocity profiles than for sine waves of the same fundamental spatial frequency. Sensitivity for square waves depended on the phase of the waveform with respect to the fixation point, w...
متن کاملAuditory motion affects visual biological motion processing.
The processing of biological motion is a critical, everyday task performed with remarkable efficiency by human sensory systems. Interest in this ability has focused to a large extent on biological motion processing in the visual modality (see, for example, Cutting, J. E., Moore, C., & Morrison, R. (1988). Masking the motions of human gait. Perception and Psychophysics, 44(4), 339-347). In natur...
متن کاملAsymmetry in visual motion processing.
The smooth pursuit system is traditionally employed using a single small target moving on a homogeneous background. It still is not fully understood, however, how accurate tracking is sustained in the presence of a structured background, which will activate global motion processing in the opposite direction as a consequence of the ongoing eye movement. To further study this interaction, we used...
