Xander is a 5-month old who is intrigued by a fancy rattle. when his caretaker takes the rattle away, he begins looking at the kitchen light in
the background and does not seem to look for the rattle. which of the following is true of this scenario?

a. xander is in the preoperational stage of development
b. xander has developed a sense of egocentrism
c. xander is clearly in the concrete operations stage
d. xander has not yet attained object permanence

The correct answer is C. Xander has not yet attained object permanence.

Explanation:

According to Piaget's Stages of Cognitive Development, object permanence occurs during the Sensorimotor Stage (birth- 2 years old), in which an infant understands that an object is still there even if it cannot be seen.

In this case, Xander has not yet obtained object permanence since as soon as the rattle is taken away, for him it has ceased to exist, thus making him be interested in other stimulus.
