The time course of lexical activation: Sequential constraint, co-articulatory preview and additional processing time

Cynthia M. Connine

Three experiments are reported that examine the manner in which lexical information unfolding over time modulates lexical activation. Three word lengths (one, two and three or more syllables) were used to manipulate the degree of constraint afforded the word-final target phoneme.

An additional manipulation (developed in Experiment 1) permits a measure of changes in activation given additional processing time where a silent interval is introduced prior to the target phoneme. The silent interval facilitates phoneme monitoring reaction time and provides a sensitive measure of the time course of lexical activation. Experiment 2 manipulates degree of activation via mismatching segments and shows that information subsequent to the mismatch is utilized to modulate activation in a manner dependent on word length and the availability of additional processing time. Experiment 3 examines the time course of co-articulatory effects as a function of word length and processing time. Taken together, the results show a dynamic use of information over time where information across the extent of a word contributes to lexical activation. Complimentary to this, activation of lexical representations is not statically tied to acoustic-phonetic input but benefits from additional processing time.
