Transfer effects of recursive self-feedback on connected speech production in patients with chronic nonfluent aphasia: Preliminary results

Background Persons with nonfluent aphasia (PWNA) have deficits with online feedback for speech error detection and correction which have debilitating effects on language relearning in learned and novel contexts. Previous studies have shown that aphasia treatments that combine PWNA's offline self-feedback and external feedback from speech-language pathologists (SLPs) improve language production in learned and novel contexts. However, it remains unclear whether PWNA can use their offline self-feedback alone during treatments that generalizes to improvement in connected speech production. Here, we examine generalization effects of recursive self-feedback on PWNA's connected speech production. Recursive self-feedback utilizes offline self-feedback loops alone to help PWNA optimize their error monitoring and correction abilities for language production in learned and novel contexts.
