When visual information is available, human adults, but not children, have been shown to reduce sensory uncertainty by taking a weighted average of sensory cues. In the absence of reliable visual information (e.g. extremely dark environment, visual disorders), the use of other information is vital. Here we ask how humans combine haptic and…

Children with developmental disorders often have poor motor performance. This study aimed to address the association between tactile localization ability, an indicator of body image, and motor function in children with motor deficits. Eighteen children with motor deficits participated, and their upper and lower limbs were assessed. To assess the…

The integrated use of spatial and temporal information seems to support the separation of two sensory streams. The present study tested whether this facilitation depends on the encoding of sensory stimuli in externally anchored spatial coordinate systems. Fifty-nine children between 5 and 12 years as well as 12 young adults performed a crossmodal…

Preschoolers who explore objects haptically often fail to recognize those objects in subsequent visual tests. This suggests that children may represent qualitatively different information in vision and haptics and/or that children's haptic perception may be poor. In this study, 72 children (2 1/2-5 years of age) and 20 adults explored unfamiliar…

Investigates the development of lateralization of cerebral function for touch and assesses whether deaf children's lateralization pattern for this sensory system shows any deviations from that of normal children. Three groups of right-handed subjects voluntarily participated in a unimodal haptic matching task: hearing adults, hearing children, and…

Investigated the relative effects of developmental level and domain-specific knowledge on 4- to 9-year-olds' ability to identify and make similarity decisions about objects based on haptic or tactile information. Found that older children explored models more exhaustively, found more differentiating features, and made fewer errors than younger…

Among 294 children of three to eight years, tactual oddity learning increased gradually with age. The finding of bidirectional cross-modal transfer of oddity learning supported the suggestion that such transfer occurs when training and transfer oddity tasks share a common vehicle dimension. Results are considered consistent with the view that…

The developmental change from global toward dimensional classifications, usually observed in vision, was investigated in haptics with stimuli varying according to their size and roughness. Results indicated that, although more overall similarity classifications were observed in children than in adults, this kind of classification was never…

Examines the haptic judgments of an L figure across the ages of 6, 7, 9, 11, 12, 13, and 20 years. Significant differences in the amount of haptic illusion were found. (MP)

This study examined the relationship between auditory, visual, touch, and oral sensory dysfunction in autism and their relationship to multisensory dysfunction and severity of autism. The Sensory Profile was completed on 104 persons with a diagnosis of autism, 3 to 56 years of age. Analysis showed a significant correlation between the different…

The main problem of this study was to examine the set characteristics of children at various age levels. Subjects were observed according to their ease of excitability and extinction in the haptic and visual modalities. Set patterns were examined at different age levels to determine if there was any trend from one age to another. The findings…
