Mrs. Pearson cut Judy's hot dog into eight pieces and Sylvia's into six pieces. Sylvia cried because she felt she wasn't getting as much hot dog as Judy. Piaget would say that Sylvia doesn't understand the principle of:a. object permanence.

b. object equivalence.

c. assimilation.

d. conservation.

e. accommodation.

D. The principle of conservation

Explanation:

According to the psychologist Jean Piaget., conservation is a logical thinking ability that allows a person to determine that a certain quantity will remain the same despite adjustments in the shape, contained, or apparent size.

Sylvia couldn't understand that it was still the same bulk quantity of hot dog, regardless of the fact that it was cut into six pieces rather than eight.

This mental ability is covered under the principle of conservation by Jean Piaget. Thus making the answer D.

Option A is wrong. This is because object permanence covers the child's ability to understand that objects still exist even if they are not visible. This is not the case here as the hot dogs were still very visible.

Option B is wrong. This is because object equivalence is a principle that is used to relate two objects together based on their similarities. This is not the case here as, Sylvia already knew that hers was still a hot dog. However, her problem was that she felt it was of a lesser quantity

Option C is wrong. This is because assimilation is a cognitive process that covers how we take in new information and relate them to the ones we already know. This is not the case discussed in the above problem. because Sylvia was not exposed to any new material.

Option E is wrong. This is because accommodation is a term also developed by psychologist Jean Piaget to describe what occurs when new information or experiences cause you to modify your existing schemas. This is also not the case as there was also no new material introduced in the problem above.
