Reducing perseverations in a Spanish speaker with aphasia: A case study

摘要

A single-subject design was utilized to examine treatment outcomes following implementation of an activation theory based treatment for perseveration. Treatment involved the use of systematic reduction of inter-stimulus interval paired with semantic feature analysis. The treatment resulted on a decrease in perseveration and increase in accuracy on trained lists. A decrease in preservations was evident from pre- to post- treatment performance on the BNT.
