Information Processing Biases in Adults Who Stutter
Information Processing Biases in Adults Who Stutter: Behavioral and Eye-tracking Indices of Threat-related Attention Allocation
University of Memphis
80 participants
Sep 11, 2023
INTERVENTIONAL
Conditions
Summary
The goal of this clinical trial is to examine whether stuttering is associated with a tendency to attend more quickly or for longer durations to threat-related information in the environment (threat-related attention bias). The main questions it aims to answer are: Do adults who stutter, relative to adults who do not stutter, attend to threat-related stimuli more than neutral information? Are attentional biases observed across different types of threat or are they specific to threats related to stuttering experiences? Do measures of attention bias explain individual differences in psychological reactions among adults who stutter?
