Speech Disfluencies as Actual and Believed Cues to Deception: Individuality of Liars and the Collective of Listeners

Nette Vandenhouwe & Robert J. Hartsuiker
There is no consensus about the relationship between disfluencies and deception in speech production. However, it is well established that listeners believe deceptive speech to contain more disfluencies than truthful speech. Here, we used an interactive game to collect the speech of liars and the veracity decisions of listeners. Using Multivariate Pattern Analysis (MVPA), we determined the predictive value of speech disfluencies as both actual and believed cues to deception. We found that patterns of...

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

Aurélie Pistono & Robert J. Hartsuiker
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...
