Word-form related disfluency versus lemma related disfluency: an exploratory analysis of disfluency patterns in connected- speech production

Several language production levels may be involved in the production of disfluencies. In the current study, we conducted network task experiments to tackle disfluencies related to conceptualization, which we operationalized by impeding visual object recognition (i.e. blurring). Contrary to what was expected, blurriness did not lead to more disfluency. However, disfluency type and disfluency location were closely related. This suggests a distinction in the underlying function of disfluencies, some reflecting word-form related difficulties, others reflecting lemma related difficulties.
