To examine the similarity and relevancy between AB error in Stage IV and in Stage V, 6 serial invisible displacement hiding tasks were administered to twelve 12 to 18 month-old babies. Those tasks were combined with two delay-time conditions (0 and 3 sec.) and three conditions of different spatial cues. Similar to Stage IV, both delay-time and spatial conditions were proved to have influenced on the occurrence rate of search errors in Stage V's invisible displacement hiding tasks. Also, residual responses similar to Stage IV were observed. Factors contributing to search errors from Stage IV to V and their developmental changes were argued. Most specifically, baby's tendency to cope at first egocentrically with the new task situation was suggested.
