Processing Of Language Switches In Bilingual Individuals With Aphasia: An Event-Related Potential Comparison, Lizette Rodarte
Processing Of Language Switches In Bilingual Individuals With Aphasia: An Event-Related Potential Comparison, Lizette Rodarte
Open Access Theses & Dissertations
Switching between languages, or code-switching, is a common phenomenon in bilingual individuals. In proficient bilinguals, these switches are done with ease and are used for many purposes. Contrary to popular belief, these switches are rule-governed and follow grammatical structure. Bilingual individuals diagnosed with aphasia present with difficulty processing languages and these language switches. With the increase in bilingual individuals, it is likely that the speech-language pathology community will see an increase of bilingual individuals with aphasia on their caseload. For this reason, the purpose of this study is to increase our understanding of the neural processes involved in processing of …
Event Related Potentials In A Two Stimuli Auditory Oddball Task In Concussed College Athletes: A Linguistic Component Replication Study, Christopher Anthony Roosmalen
Event Related Potentials In A Two Stimuli Auditory Oddball Task In Concussed College Athletes: A Linguistic Component Replication Study, Christopher Anthony Roosmalen
Open Access Theses & Dissertations
Concussions affect an estimated 1.6 to 3.8 million individuals annually and can result in persistent symptoms and cognitive impairments in attention and memory. Concussions are a rising health concern especially in concussion management. Event Related Potentials (ERP) may more accurately assess cognitive recovery making better return to play decisions. In 2013, Sanchez found no significant difference between concussed athletes and non-concussed individuals in the in amplitude of the P300 ERP component using an auditory oddball task consisting of 2 different consonant, vowel (CV) syllables. Because participants were instructed to maintain a mental and verbal count of the target stimuli, a …
Event Related Potential Changes In A Two-Stimulus Auditory Oddball Task In Concussed College Athletes: A Linguistic Component, Paola G. Sanchez
Event Related Potential Changes In A Two-Stimulus Auditory Oddball Task In Concussed College Athletes: A Linguistic Component, Paola G. Sanchez
Open Access Theses & Dissertations
"Return to Play" decisions are done based on cognitive-communicative testing and clinical assessments; concussed athletes may benefit from electrophysiological testing for a more accurate representation of their recovery. The purpose of this study is to investigate the electrophysiological performance post-concussion analyzing the attentional differences using the traditional "oddball" paradigm with a CV linguistic component. Participants for this study were 6 male college athletes with a history of concussion and 10 participants with no history of concussion (controls). Athletes were evaluated using event-related potentials (ERPs) that were recorded during a consonant-vowel (CV) auditory oddball task. Both the P300a and P300b components …
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 …
