Executive Control in Adults Who Stutter: The Antisaccade Task

Purpose: The purpose of this study was to investigate executive control in adults who stutter (AWS) and adults who do not stutter (AWNS) via a nonspeech paradigm, wherein eye movements were monitored (i.e., antisaccade task). Processes involved in an antisaccade task include working memory, attention, and voluntary motor control, but the task primarily provides insight into inhibitory control. Method: Seventeen AWS (14 men, three women; M = 23.41 years) and 17 AWNS (M = 23.29 years) were presented with a combination of prosaccade (i.e., looking toward a target) and antisaccade (i.e., suppress a reflexive saccade toward the target and look in the opposite direction) trials. The distance of the target from the center of the screen was also manipulated (i.e., 5.5o = short distance and 10.8o = long distance). Data for accuracy and reaction time of the first accurate saccade were collected and analyzed. Results: No difference was found between AWS and AWNS in accuracy or in reaction time. Both groups were more accurate in the prosaccade than the antisaccade trials and in the long compared to the short distance trials. Furthermore, both groups demonstrated longer saccade latencies for long compared to short distances and for antisaccade compared to prosaccade trials. Conclusions: Preliminary results do not support deficits in inhibition in AWS during a motorically simple, non-speech-related oculomotor task, but additional research is warranted.
