Projects:FrontoTemporalConnectivityInSchizophreniaDuringSemanticMemory

Back to NA-MIC_Collaborations

Objective: In this project, an event-related auditory semantic memory task is administered. Participants are presented with a semantic category and required to decide whether a subsequent word is a member of the category (e.g., vehicle-bus). To control for phonological processing, other items require a match-mismatch decision between pseudo-words constructed from reordered semantic items (e.g., yodb-rea).

Progress: To date, 6 patients with schizophrenia and 3 healthy controls have been studied with this task. Data will be available in year three.

Year Three Update: Data collection and analysis is ongoing. Updated results are expected at the end of year three.
