Effects of time pressure on mechanisms of speech production and self-monitoring

The purpose of the present study was to examine effects of rime pressure on mechanisms of speech production and self-monitoring, The most widely accepted monitoring theory (Levelt, 1989) suggests that monitoring proceeds through language perception, that is. speech error detection is primarily based on the parsing of one's own inner and overt speech. Twenty-four subjects described visual networks at two different rates (normal and fast). The time pressure manipulation affected a number of temporal characteristics: the error to cutoff and cutoff to repair times, were shorter in the fast than in the normal condition. The results indicate that the monitor adjusts its speed of error detection and repair planning to the faster speech output rate. The time pressure manipulation did not affect the accuracy of error detection. The implications for the perception theory of monitoring are discussed.
