An accelerometer-based handheld system to reduce breaks in performance of young adults with cognitive impairments.

This study assessed the possibility of training two individuals with cognitive impairments using a system that reduced breaks in performance. This study was carried out according to an ABAB sequence in which A represented the baseline and B represented intervention phases. Data showed that the two participants significantly increased their target response, thus reducing breaks and improving vocational job performance during the intervention phases. Practical and developmental implications of the findings are discussed.
