Temporal Gestures in Different Temporal Perspectives.

Temporal perspectives allow us to place ourselves and temporal events on a timeline, making it easier to conceptualize time. This study investigates how we take different temporal perspectives in our temporal gestures. We asked participants (n = 36) to retell temporal scenarios written in the Moving-Ego, Moving-Time, and Time-Reference-Point perspectives in spontaneous and encouraged gesture conditions. Participants took temporal perspectives mostly in similar ways regardless of the gesture condition. Perspective comparisons showed that temporal gestures of our participants resonated better with the Ego- (i.e., Moving-Ego and Moving-Time) versus Time-Reference-Point distinction instead of the classical Moving-Ego versus Moving-Time contrast. Specifically, participants mostly produced more Moving-Ego and Time-Reference-Point gestures for the corresponding scenarios and speech; however, the Moving-Time perspective was not adopted more than the others in any condition. Similarly, the Moving-Time gestures did not favor an axis over the others, whereas Moving-Ego gestures were mostly sagittal and Time-Reference-Point gestures were mostly lateral. These findings suggest that we incorporate temporal perspectives into our temporal gestures to a considerable extent; however, the classical Moving-Ego and Moving-Time classification may not hold for temporal gestures.
