Purpose:
Aphasia rehabilitation is a learning process that unfolds over time. Previous group studies have examined aphasia treatment response using pre- to posttreatment comparison, largely ignoring the unfolding learning response that occurs session-to-session. We aimed to (a) characterize the shape of learning while individuals with aphasia received intensive anomia intervention and (b) identify the cognitive predictors of this learning response.
Method:
Individuals (N = 39) with chronic poststroke aphasia received intensive semantic feature analysis (SFA). Naming accuracy for trained and semantically related, untrained words was probed daily. We used Bayesian generalized linear mixed-effects models to estimate the shape of learning during SFA treatment and to measure the influence of key cognitive functions on treatment response.
Results:
Most treatment gains appeared early during treatment, after the first 4 hr of intervention. Verbal recognition and visuospatial memory were associated with the magnitude of those early treatment gains, favoring strong cognitive performers. Treatment generalization to untrained targets was present but modest, with some evidence suggesting that visuospatial recall performance may be associated with treatment generalization.
Conclusions:
Monitoring SFA treatment response early could help inform clinicians whether patients will respond optimally to intervention. Verbal recognition and visuospatial recall support learning during treatment, helping elucidate cognitive underpinnings of learning during aphasia rehabilitation.

Cognitive Learning
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...
