• We measured the influence of the spatio-temporal aspects of observed actions on action prediction.
• Twelve-month-olds saw manual actions with different movement distances and durations.
• We found that movement duration, distance, velocity and type influenced action prediction.
The goal of the present study was to test the influence of the spatial and temporal dynamics of observed manual actions on infants’ action prediction. Twelve-month-old infants were presented with reach-and-transport actions performed by a human agent. Movement distance, duration, and – resulting from the two – movement velocity were systematically varied. Action prediction was measured via the latency of gaze arrival at target in relation to agent’s hand. The results showed a general effect of all parameters on the infants’ perception of goal-directed actions: Infants were more likely to predict the action goal the longer the movement distance was, the longer the movement duration was, and the slower the movement velocity was. In addition, they were more likely to predict the goal of a reaching than a transport action. The present findings extent previous findings by showing that infants are not only sensitive to differences in distances, durations, and velocities at early age but that these factors have a strong impact on the prediction of the goal of observed actions.
