Cognitive Load Increases Spoken and Gestural Hesitation Frequency

This study investigates the interplay of spoken and gestural hesitations under varying amounts cognitive load. We argue that not only fillers silences, as most common hesitations, are directly related to speech pausing behavior, but hesitation lengthening is well. designed a resource-management card game method elicit ecologically valid behavior while being able finely control load via complexity.
