Abstract
Motivational theories of imitation state that we imitate because this led to positive social consequences in the past. Because movement imitation typically only leads to these consequences when perceived by the imitated person, it should increase when the interaction partner sees the imitator. Current evidence for this hypothesis is mixed, potentially due to the low ecological validity in previous studies. We conducted two experiments (NExperiment 1 = 94, NExperiment 2 = 110) in which we resolved this limitation by placing participants in a virtual environment with a seeing and a blindfolded virtual agent, where they reacted to auditory cues with a head movement to the left or right, while the agent(s) also made a left or right head movement. Wetested the effect of model eyesight (Experiments 1 and 2) and social reward on imitation (Experiment 2). Data were collected in 2023 and 2024. As expected, participants tended to imitate the agents. However, we found only limited evidence for the effect of model eyesight on automatic imitation in Experiment 1 and no evidence for the effect of model eyesight or social reward in Experiment 2. These findings challenge claims made by motivational theories.
