Previous studies have indicated that visual-auditory temporal acuity is reduced in children with autism spectrum conditions (ASC) in comparison to neurotypicals. In the present study we investigated temporal acuity for all possible bimodal pairings of visual, tactile and auditory information in adults with ASC (n = 18) and a matched control group…

Children from 4 to 7 years of age were tested in a structured perceptual task in which haptic manipulation was available, but not required. The extent of haptic involvement with the stimulus material and its effect on performance in a perceptual recognition task was then determined. (Author/CB)

Dimensional preference tasks in both visual and haptic modalities with three dimensional stimuli varying in form, size, color, or texture were presented to 64 children. There were 16 subjects at each of four grade levels: preschool, kindergarten, grade 1, and grade 3. On each trial, the subject was presented three stimuli and asked to tell the…

Two experiments were conducted to investigate the perceptual processes involved in haptic exploration of randomly generated shapes. Experiment one required subjects to detect symmetrical or asymmetrical characteristics of individually presented plastic shapes, also varying in complexity. Scanning time for both symmetrical and asymmetrical shapes…
