Brief 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
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
Detailed Description:
The goal of the project is to examine threat-related attentional processes associated with stuttering In Aim 1 investigators will establish differences in attention bias AB in adults who do and do not stutter and the processing stage at which differences emerge In Aim 2 investigators will compare AB effects across different categories of threat stimuli to determine whether threat-related AB in adults who stutter is general or disorder-specific In Aim 3 the investigators examine the role of AB as a causal factor mediating effects of individual risk-factors related to temperament and attention control on stuttering impact and anticipation Participants will include 35 adults who stutter and 35 adults who stutter between the ages of 18-30 years all meeting specified eligibility criteria All participants will complete three experimental tasks for measuring AB 1 a free-viewing task 2 dot-probe task and 3 emotional Stroop task Study procedures will be administered over two sessions 2-25 hours each scheduled within three weeks of each other Key outcomes will include reaction time and eye-tracking measures which will be used to extract multiple AB indices Data will be analyzed via mixed-effects regression analysis with a random intercept for subject and maximal converging random-slopes structure Age gender socioeconomic status and various measures used for inclusion purposes will be included as covariates Mediation analyses will assess four relationships Temperament - Stuttering impact Temperament - Anticipation Attention control - Stuttering impact and Attention control - Anticipation with AB as the mediator variable in each analysis
