We identified clusters of atypical sensory functioning adults with ASC by hierarchical cluster analysis. A new scale for commonly self-reported sensory reactivity was used as a measure. In a low frequency group (n = 37), all subscale scores were relatively low, in particular atypical sensory/motor reactivity. In the intermediate group (n = 17)…

D. R. Proffitt and colleagues (e. g., D. R. Proffitt, J. Stefanucci, T. Banton, & W. Epstein, 2003) have suggested that objects appear farther away if more effort is required to act upon them (e.g., by having to throw a ball).

Dysregulation of activity linked with development was analysed in 12 children with intellectual disabilities (ID) and in 12 children with autism (ASD) matched on their developmental age (18 months). The "Batterie d'Evaluation du Developpement Cognitif et Social" [Adrien, J. L. (1996). "Autisme du jeune enfant. Developpement…

A study was conducted to investigate the power of motor coordination for estimating intellectual performance and personality characteristics. Comparisons of the results were made by using two statistical techniques, univariate and multivariate, in terms of the appropriate technique for analyzing the data. Data consisting of six intellectual tests,…
