Participants saw a small number of objects in a visual display and performed a visual detection or visual-discrimination task in the context of task-irrelevant spoken distractors. In each experiment, a visual cue was presented 400 ms after the onset of a spoken word. In experiments 1 and 2, the cue was an isoluminant color change and participants…

Prior research indicates that synchronized tapping performance is very poor with flashing visual stimuli compared with auditory stimuli. Three finger-tapping experiments compared flashing visual metronomes with visual metronomes containing a spatial component, either compatible, incompatible, or orthogonal to the tapping action. In Experiment 1,…

Models of interhemispheric interference have been proposed as an explanation for the cause and maintenance of stuttering. One component of this model is attentional functioning and allocation. This study examined attentional functioning in 19 children who stuttered and 19 children who did not stutter using a standardized, commercially available…
