would directly impact upon speech and language therapy intervention techniques. In addition, speech and language therapists would need to consider the adaptation of therapy tools and methods in order to promote new learning processes in therapy. In conclusion, this investigation has established that adults with aphasia can learn new language representations in the form of new vocabulary despite a range of severity of aphasia and other influencing factors. This information needs to be considered in future rehabilitation efficacy studies in terms of methodology. Further investigations are required to contribute to the development of a theory of language rehabilitation with a view to providing people with aphasia with the best opportunity for the restitution of language functioning. 289
