A preoperational child’s belief that a tall, narrow glass contains more liquid than a short, wide glass is probably due to difficulties in
A. decentering. B. egocentrism. C. serration. D. object permanence.
Explanation: A) Decentering is the ability to focus on more than one aspect of a situation at a time. This occurs, for example, when the preoperational child perceives that, because a glass is taller, it must also have more liquid. In this case, the child is unable to see that the amount of liquid has not changed.
