N1 - Funding Information:
This study was funded in part by grants from the Wallace Research Foundation and NICHD (R03HD049532) to PLD & WJG and by Helen F. McHugh Graduate Fellowship to W-PC. Thanks to Dr. Lucy J. Miller, OTR for loaning the project use of her EEG system. This study could not have been completed without her generosity. We appreciate the assistance of Lisa Fyffe, MS, OTR, who was very helpful in recruiting children with SPD. We thank Barb Brett-Green for scoring the ERPs for inter-rater reliability. Finally, we wish to thank all of the children and their families whose participation made this study possible.

N2 - Recent interest in sensory gating in children with and without neuropsychological disorders has resulted in a number of studies and the results regarding the developmental trajectory of sensory gating are inconsistent. We investigated the maturational course of sensory gating in samples of typically developing children and children with sensory processing deficits (SPD) and compared their performance to adults. Besides gating ratios, we also examined the brain responses to conditioning and test click stimuli in the sensory gating paradigm separately to clarify if the changes in click amplitudes could explain the maturational change in the T/C ratio in children. Eighteen adults with no known disorders, 25 typical children, and 28 children with SPD participated in this study. The children ranged in ages between 5 and 12 years. The three groups differed in their P50 and N100 ERP components. Both child groups displayed significantly less gating than the adults. Children with SPD demonstrated significantly less gating and more within-group variability compared to typical children. There were significant relationships between age and T/C ratios and between age and peak-to-peak amplitude of the conditioning click in typical children but not in children with SPD. Typical children demonstrated significantly smaller brain response amplitudes to the clicks as compared to adults. These findings suggest that there is a maturational course of sensory gating in typical children and if there is a maturational trajectory in children with SPD it appears to be different than typical children. In addition, children with SPD were found to be lacking in their ability to filter out repeated auditory input and failed to selectively regulate their sensitivity to sensory stimuli.
