This review paper introduces some researches about the attention allocation of poststroke aphasic patients, using attention resources theory and dual-task paradigm, as well as other researches about the application of attention training in speech rehabilitation. The potential value of these researches is to set related speech rehabilitation measures for the aphasic patients.
