Abstract
This research investigated the developmental relationship between young children's performance on a mark test and on an object-reaching test using video images. Forty-three young children (ages 30–43 months) participated in the experiment. After performing the mark test, children experienced three main conditions of the object-reaching test on which they were asked to find the real target doll only by looking at its televised image. The results showed that a video-elicited correct search for a target which appeared behind the children's back was far more difficult than a search for a mark on their heads. This was especially true of the results obtained for one of the front/back conditions, whereby two stands were presented in front and at the back of the child at the same time and that the target was put only on the front or back. In this condition, many of chilren who passed the mark test made an incorrect search toward the front stand.
