It was hypothesized that cognitive flexibility may influence aphasic individuals’ ability to generalize techniques learned in therapy to more functional communication situations. A cognitive flexibility score was created by examination of modality switching behavior on the CADL and on a referential communication task, following multimodality training. A multiple regression analysis revealed a significant correlation between the CADL cognitive flexibility score and the referential communication task, but the contribution of the PICA was not significant. These results suggest the cognitive flexibility score is independent of language function and may help predict whether patients would benefit from specific strategy training
