Assessing Cortical Electrophysiologic And Behavioral Activity In Individuals With Aphasia And Participants With No Brain Damage Responding To Spoken Sentence Length Messages, Patricia Lara
Open Access Theses & Dissertations
In this study, six individuals with aphasia and twelve participants with no brain damage responded to spoken sentence length messages using a modified version of the Revised Token Test (McNeil & Prescott, 1978) while cortical activation was recorded using event related potentials (ERP). ERP is a non-invasive imaging procedure that measures cortical activation reflected in the electrical activity that is produced at the level of the cortex in response to internal or external stimulus.
Participants were presented with a visual display that provided eight different token arrangements per trial that were displayed on the computer screen. Spoken messages that increased …
