Much evidence suggests that visual motion can cause severe distortions in the perception of spatial position. In this study, we show that visual motion also distorts saccadic eye movements. Landing positions of saccades performed to objects presented in the vicinity of visual motion were biased in the direction of motion. The targeting errors for both saccades and perceptual reports were maximu...

Understanding the development of spatial cognition during childhood is important. Paying close attention to development provides a lens through with to explore mechanisms that underlie stability and change in perception, memory, language, and symbolic understanding over time. This symposium, moderated by Alycia Hund, includes four talks highlighting tight links between spatial perception of mid...

INTRODUCTION The compact disc (CD) format records audio with 16-bit resolution at a sampling rate of 44.1 kHz. This format was engineered to reproduce audio with fidelity exceeding the limits of human perception, and it works. However, sound is inherently a spatial perception. We perceive the direction, distance, and size of sound sources. Accurate reproduction of the spatial properties of soun...

Traditional vector and raster spatial models as used in many computer systems are examined to determine what is meant by the term “neighbour”. The limitations are examined and the Voronoi spatial model is proposed as a consistent alternative to both. It is then asked whether this new computer model of space bears any resemblance to human spatial reasoning and perception processes. Examination o...

For images, stochastic resonance or useful-noise effects have previously been assessed with low-level pixel-based information measures. Such measures are not sensitive to coherent spatial structures usually existing in images. As a result, we show that such measures are not sufficient to properly account for stochastic resonance occurring in visual perception. We introduce higher-level similari...

The aim of the present study was to show that space perception depends on sensori-motor experience. We induced spatial biases by a non-conflictual lateralized sensori-motor task on twenty seven right-handed healthy volunteers (left-to-right readers). After a pre-test and before a post-test, which assessed visuo-motor and perceptual subjective midpoint in line bisection, participants performed a...

The perception-action model proposes that vision for perception and vision for action are subserved by two separate cortical systems, the ventral and dorsal streams, respectively [Milner, A. D., & Goodale, M. A. (1995). The visual brain in action (1st ed.). Oxford: Oxford University Press; Milner, A. D., & Goodale, M. A. (2006). The visual brain in action (2nd ed.). Oxford: Oxford University Pr...

While early research suggested that peripheral vision dominates the perception of self-motion, subsequent studies found little or no effect of stimulus eccentricity. In contradiction to these broad notions of 'peripheral dominance' and 'eccentricity independence', the present experiments showed that the spatial frequency of optic flow interacts with its eccentricity to determine circular vectio...
