An OTR is running а grоup fоr TBI pаtients оn аn inpatient rehabilitation unit. One week into the group (after 5 sessions) the therapist notes that one of the clients has trouble initiating conversation with group members that he has spoken to freely during previous sessions. The therapist suspects that the client is having trouble remembering the names and faces of other group members and doesn't realize that he already knows them. What standardized assessment could the therapist give to help answer this question?
