Abstract
Background.
Persons with aphasia often present with low mood/depression, which can
negatively affect their quality of life.(Precisely because you have NO PROTOCOLS FOR RECOVERY. SOLVE THE CORRECT PROBLEM, APHASIA, not depression.)The validity and reliability of
existing depression measures for aphasia have been called into
question. Eye tracking in nonstroke populations is reliable in
identifying low mood/depression. Depressed persons are biased to
negative emotions compared with nondepressed persons and have an absence
of bias to positive emotions. However, nondepressed persons may be
biased to positive emotions.
Objective.
To examine the feasibility of using eye tracking to measure mood in persons with aphasia.
Methods.
We recruited 22 persons with chronic aphasia and 12 healthy controls.
Participants completed 2 self-report measures of mood. They also viewed
faces that showed happy, sad, and neutral facial expressions during eye
tracking. We analyzed 2 eye tracking indices: initial gaze orientation
and gaze maintenance to happy, sad, and neutral faces.
Results.
For initial gaze orientation, participants with aphasia fixated faster
on emotional faces compared with healthy controls but directed their
gaze less often to happy faces compared with healthy controls. For gaze
maintenance components, the duration of first fixation and total
fixation duration were shorter on sad faces for participants with
aphasia compared with healthy controls.
Conclusion.
Use of eye
tracking with faces representing different mood states is feasible in
persons with aphasia. Although there were some similarities,
participants with aphasia had different gaze patterns to emotional faces
compared with healthy controls. Further research is needed to establish
whether this is a valid and reliable method of mood assessment.
