The Interaction Between Processing Speed, Cognitive Control, and Word Retrieval

Abstract: When speakers retrieve words, they do so extremely quickly and accurately - both speed and accuracy of word retrieval are compromised in persons with aphasia (PWA). This talk examines the contribution of two domain general mechanisms: processing speed and cognitive control on word retrieval in three groups: young adults, older adults and PWA. We found that both aging and aphasia resulted in slower response times, but did not affect cognitive control. While both neurotypical groups showed a strong association between cognitive control and word retrieval speed, older adults's word retrieval speeds also showed an association with processing speed. PWA, showed no association between word retrieval, processing speed and cognitive control, showing a decoupling of domain general mechanisms from word retrieval. Implications of these findings for models of word production and aphasia will be presented.
