Developmental trends in haptic and visual free classifications: influence of stimulus structure and exploration on decisional processes

Article Abstract:

Characteristics of exploratory conditions and presentation of dimensions influence the dissimilarities between haptic and visual free classifications in young children and adults. Different exploratory conditions for haptic classification and simultaneous versus independent presentation of dimensions for visual sorting were tested. The results may be explained by children's preference for information presented earlier, and by adults' preference for information presented later.

The reproduction of vertical and oblique orientations in the visual, haptic, and somato-vestibular systems

Article Abstract:

This article investigates the processes involved in the human reproduction of spatial orientations during tasks that rely on visual, tactual-kinesthetic, and somato-vestribular perception. Findings indicate that subjects required to reproduce the position of a moveable rod or rotating chair use vertical orientation as a perceptual reference to reproduce oblique orientations.

Attentional orienting in two-dimensional space

Article Abstract:

The effect of advance cues on visual orientation to objects within a field is examined, focusing on central and peripheral cues. Experiments monitored eye movements and simple manual responses and results reported on saccadic latencies, meridional effects, cue-target distance effects, relative eccentricity effects, and saccade gains.
