An experiment was conducted to examine whether visual perspective has an effect on visuomotor imitation. The experiment presented varied visual perspectives in terms of spatial disparity between a model and an observer (model-observer-disparity) on six levels. Female participants were asked to imitate different arm movements presented in videos by animated models. These arm movements were elbow-extension-flexion movements with one (lower complexity) or three (higher complexity) reversals of movement direction. The results showed that model-observer-disparity affects spatial trajectories and velocities in the performance of motor imitations. The movements’ complexity did not affect orientation dependence. Due to the non-linearity of the data, it is questionable if orientation dependence can be at least partially explained by mental rotation processes or differential ideomotor effects. According to these results, high model-observer-disparity should be avoided when using visual instructions in visuomotor imitation.
► Arm Movements of Video models with varied model-observer-disparity were imitated. ► Model orientation affected spatial and temporal variables of imitation performance. ► Movement complexity did not influence the orientation dependence. ► High model-observer-disparity should be avoided when using video instructions. ► Mental rotation processes and orientation dependent ideomotor effects are discussed.
