Exploring Methods of Communication in Patients with Aphasia Jonathan Canton UC Merced
Previous Research Types Aphasia has been studied for many years. There are varying types of aphasia, but the two main categories are Broca and Wernicke’s Aphasia. Related Studies 1.The subjects were tested on their ability to express what was happening in a picture that consisted of a subject and an action. (Hillis, Heidler-Gary, Newhart, Chang, Ken, Bak, 2006) 2. The subjects were given a visual stimuli and were evaluated based on the recordings of actions and gestures they performed in reaction to astimuli (Mol, Krahmer, van de Sandt-Koenderman, 2013) 3. The neurological processes of two individuals afflicted with aphasia were examined (Cairns, Marshall, Cairns, Dipper 2007).
Proposal/Hypothesis Purpose - To dispel misconception regarding aphasia and intelligence and to further explore effective means of communication for patients with non-fluent (Broca’s) Aphasia. Hypothesis – If the patient exhibits appropriate brain function and physical gestures in correspondence to an audiovisual stimuli, then it can be inferred that the patient has the capacity to respond to speech in effective manners, despite their brain damage.
Experimental Design Participants • Full Consent • 20 Aphasic/ 20 Control Methods/Procedures - One initial 2-day session and another 2-day session at least 6 months later. - Separate into 3 groups: Mild Aphasia, Severe Aphasia, Control Group - Engage each participant individually by use of audiovisual stimuli and evaluate patient’s response through EEG and video recordings .
Expected Results Best Case Scenario Worst Case Scenario -The patient is completely unresponsive and shows completely uncorrelated physical responses and brain functions in response to an audiovisual stimuli. - The most likely scenario would be that the researchers observe a positive correlation between the appropriate brain activity and the physical gestures and responses that the patients give. -Aphasic patients show similar Intellect and brain functions to normal people. Impaired, but similar gestures as well.
Conclusion - Broca’s Aphasia, or any other form of aphasia, is not related to intelligence. • To help find ways of helping aphasic patients communicate their thoughts in an effective manner with the use of facial expressions and physical gestures.
