Categorical perception of tactile distance.
The tactile surface forms a continuous sheet covering the body. And yet, the perceived distance between two touches varies across stimulation sites. Perceived tactile distance is larger when stimuli cross over the wrist, compared to when both fall on either the hand or the forearm. This effect could reflect a categorical distortion of tactile space across body-part boundaries (in which stimuli ...

متن کاملCategorical perception.
Categorical perception (CP) is the phenomenon by which the categories possessed by an observer influences the observers' perception. Experimentally, CP is revealed when an observer's ability to make perceptual discriminations between things is better when those things belong to different categories rather than the same category, controlling for the physical difference between the things. We con...
متن کاملThe Application of Tactile Experience in Urban Perception
Urban perception is the result of mutual transaction between human and environment and the process of perception is developed through the three continuous steps of “sensation”, “perception” and “cognition”. In the first step (sensorial perception), the environmental signals are received via sensorial sensors and each different sense based on its own essence, performance and ability has its own ...
متن کاملCategorical perception of race.
Traditionally, research demonstrating categorical perception (CP) has assumed that CP occurs only in cases where natural continua are divided categorically by long-term learning or innate perceptual programming. More recent research suggests that this may not be true, and that even novel continua between novel stimuli such as unfamiliar faces can show CP effects as well. Given this, we ask whet...
