Abstract:
A large number of self-image studies have claimed that children before two years old can recognize themselves in mirrors. This ability was tested whether children touch a covertly placed mark on their face when confronted with a mirror. In the present study, we investigated whether 2-, 3-, and 4-year-olds who passed the mirror mark test were able to use their video feedback as a reflection of their current state, even when their feedback was presented with a short temporal delay. In Experiment 1, we investigated the effect of 1- or 2-sec delayed feedback on an analog of the mark test. In the case of live or 1-sec delayed feedback, 3-year-olds were able to pass the test; however, they failed in the case of 2-sec delayed feedback. In Experiment 2, we investigated whether prior experience of 2-sec delayed feedback with explorative behaviors improves performance in the mark test. The results showed a significant effect of prior experience of delayed feedback. These results suggest that detection of visual-proprioceptive contingency contributes to recognizing a visual feedback as being one's current self.
