The influence of dimensionality on eye fixations.

abstract：:Two experiments are reported with young Down's syndrome and normal children matched for mental age, sex, and social class. In one, Down's syndrome children performed at chance level on two tactual--visual cross-modal tasks, and only the oldest succeeded with one of two visual--visual within-modal tasks. The modal chil...
