Faroqi-Shah, Yasmeen; Gehman, Megan – Journal of Speech, Language, and Hearing Research, 2021
Purpose: 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 study examined the contribution of two domain-general mechanisms: processing speed and cognitive control on word retrieval in PWA. Method: Three groups of participants,…

Moberly, Aaron C.; Reed, Jessa – Journal of Speech, Language, and Hearing Research, 2019
Purpose: Speech recognition relies upon a listener's successful pairing of the acoustic--phonetic details from the bottom-up input with top-down linguistic processing of the incoming speech stream. When the speech is spectrally degraded, such as through a cochlear implant (CI), this role of top-down processing is poorly understood. This study…

McVay, Jennifer C.; Kane, Michael J. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2012
A combined experimental, individual-differences, and thought-sampling study tested the predictions of executive attention (e.g., Engle & Kane, 2004) and coordinative binding (e.g., Oberauer, Suss, Wilhelm, & Sander, 2007) theories of working memory capacity (WMC). We assessed 288 subjects' WMC and their performance and mind-wandering rates…
