A reversed word length effect in coordinating the preparation and articulation of words in speaking.

Speakers tend to prepare their nouns immediately before saying them, rather than preparing them further in advance. To test the limits of this last-second preparation, speakers were asked to name object pairs without pausing between names. There was not enough time to prepare the second name while articulating the first, so the speakers' delay in starting to say the first name was based on the amount of time available to prepare the second name during speech. Before speaking, they spent more time preparing a second name (e.g., carrot) when the first name was monosyllabic (e.g., wig) rather than multisyllabic (e.g., windmill). When additional words intervened between names, the length of the first name became less important and speech began earlier. Preparation differences were reflected in speech latencies, durations, and eye movements. The results suggest that speakers are sensitive to the length of prepared words and the time needed for preparing subsequent words. They can use this information to increase fluency while minimizing word buffering.
