Training Metaphor Interpretation in RHD Patients: Preliminary Results

Five stroke patients with right hemisphere brain damage (RHD) participated in a single subject experimental design intervention study to train metaphor comprehension. The theory motivating the program posits roles for coarse-grained semantic knowledge and working memory. Four patients showed clear improvement in metaphor interpretation associated with the start of training. Results indicate the potential of an evidence-based approach for treating deficits associated with RHD. The paper will describe the training program and discuss individual performances on metaphor, line orientation, working memory and other background measures.
