Abstract
Visual and auditory masking tests and perceptual-motor tests were administered to 39 brain-injured, non-defective children, aged 6 to 12, and to a comparison group of intact children of the same age. The masking tests in both modalities followed a rough continuum of meaningfulness (and therefore of presumed level of distraction) of the mask. Analysis was done of inter-modal and intra-modal scores, within and between the experimental and comparison groups. Results showed that the brain-injured group had less differentiated functioning in the auditory modality, as compared with the intact group and with its own visual functioning. Results are interpreted in terms of differences between audition and vision. The susceptibility of auditory functioning to attentional disorders is also discussed.
