Labial and Laryngeal Reaction Times of Stutterers and Nonstutterers
Simple reaction time experiments, in which speech-motor capacities of stutterers and nonstutterers were compared, most often have tested laryngeal functioning. In these studies subjects were required to phonate, as quickly as possible, when a cuestimulus was presented. The results have tended to indicate that stutterers respond more slowly than do nonstutterers. This was true even though only fluent responses were analyzed to ensure that the results would not be contaminated by the presence of stuttering (Adams and Hayden, 1976; Cross and Luper, 1983; Prosek, 1978; Starkweather, Hirschman, and Tannenbaum, 1976; Watson and Alfonso, 1983).
