Studies have indicated that people with acquired brain injury (AIM) often lack knowledge about their injuries and are frequently unaware of or even deny injury residuals. As part of a neurobehavloral rehabilitation program, three adult males in this study were trained in knowledge of ABI residuals using a game format to present training information. Using a multiple baseline experimental design, the results indicated that all three participants Increased their percentage of correct responses in the study areas of behavior, emotion, cognition, communication, physical, and sensory residuals. However, subjective data related to the impact of these improvements on participant functioning were not consistent. More research is needed to determine the effects of training on participants' behavior in naturalistic situations.
