Quizplus · Accepted Answer

The ability to use mental representations marks the end of the sensorimotor period and the beginning of the preoperational period. Walking and talking typically develop during the sensorimotor period but do not mark the end of it. The decline of egocentrism is a part of the preoperational period, not the end of the sensorimotor period.
