Cortical activity for conversational responses: A functional near-infrared spectroscopy study

Cortical activity for conversational responses in young neurotypical individuals, older neurotypical individuals, and individuals with aphasia: A functional near-infrared spectroscopy study Abstract Functional near-infrared spectroscopy (fNIRS) has the potential for evaluating language and conversational interaction in an ecologically valid way given that participants can be seated and interacting with a conversational partner. Aphasia, an acquired […]

The evolution of word retrieval errors during semantic feature-based therapy in bilingual aphasia

Abstract Bilinguals with aphasia routinely experience anomia in one or both of their languages that may be ameliorated by language treatment. Traditionally, treatment response has been captured by binary scoring systems that measure the presence or absence of improvement without examining how word retrieval attempts may change over time as a function of treatment. This […]

Quantifying the impact of hair and skin characteristics on fNIRS signal quality for enhanced inclusivity
