Studies of temporal processing of multi-item visual, auditory, and tactile stimulus sequences in children with central auditory-processing disorders have shown considerable variability even among the children in the normal control group, suggesting that some aspects of complex temporal processing may continue to develop throughout childhood. In the present study, two experiments were performed. In the first, groups of normally developing children aged 8, 10, 12, and 14 years were tested with three-item sequences of auditory tones (analogous to the pitch pattern sequence test widely used in assessing central auditory-processing abilities), sequences of colored boxes, and sequences of tactile vibrations presented to different locations on the forearm. Children were asked to identify the sequence presented. Results showed significant improvements in performance with age, with most of the difference between the 8- and 10-year-old groups. A second experiment examined younger children, aged 6, 7, and 8 years, with slightly modified versions of the same tasks. Again, a significant improvement in performance with age was observed. These improvements were evident for all sensory modalities, although overall performance levels were highest for the visual task and lowest for the tactile task. Results are discussed in terms of more general development of perceptual and cognitive abilities in childhood. [Work supported by NIH.]
