Exploring semantic and phonological picture-word priming in adults who stutter using event-related potentials.

ABSTRACT:

Objective

Our aim was to investigate how semantic and phonological information is processed in adults who stutter (AWS) preparing to name pictures, following-up a report that event-related potentials (ERPs) in AWS evidenced atypical semantic picture-word priming (Maxfield et al., 2010).

Methods

Fourteen AWS and 14 typically-fluent adults (TFA) participated. Pictures, named at a delay, were followed by probe words. Design elements not used in Maxfield et al. (2010) let us evaluate both phonological and semantic picture-word priming.

Results

TFA evidenced typical priming effects in probe-elicited ERPs. AWS evidenced diminished semantic priming, and reverse phonological N400 priming.

Conclusions

Results point to atypical processing of semantic and phonological inf
