What this Trial Is About
Researchers are investigating whether adults who stutter pay more attention to threat-related information in their environment compared to adults who do not stutter. The study explores if these attention biases are general or specific to threats related to stuttering experiences and examines how these biases relate to individual psychological reactions. This trial includes adults aged 18 to 65 and aims to understand the connection between temperament, attention control, and stuttering impact. Participants will complete three tasks that involve viewing threat-related and neutral stimuli, such as words or faces. These tasks include a free-viewing task, a dot-probe task, and an emotional Stroop task. All procedures will be conducted over two sessions, each lasting 2 to 2.5 hours, scheduled within three weeks. The study uses behavioral and eye-tracking methods to collect data on attention biases. During the study, participants will have their reaction times and eye movements recorded to measure attention to threat-related stimuli. Researchers will analyze these measures to understand attention allocation and its relationship to stuttering. The study also considers factors like age, gender, and socioeconomic status in its analysis. The total involvement requires two sessions within a short time frame, with detailed experimental tasks assessing attention biases.
