 Phase II: Only people with acquired brain injury ABI will participate in Phase II activities. Phase II participants will attend two-hour, group intervention sessions one day per week for eight weeks. Participants will engage in multiple word game activities throughout each intervention session. Games will include Facts in Five, Anomia, Boggle, and Bananagrams as well as variations on these, as appropriate. Data collection during these sessions will be limited to a list of activities in which a participant engaged and the duration of engagement in each activity. Game-based group activities such as these are not typically used in intervention sessions for people with ABI who experience mild word-retrieval challenges. In fact, because of the subtlety of word retrieval difficulties experienced by people with relatively good recoveries from ABI--that is, the target population for this research--most people do not receive any treatment for this problem.
