Question

Quizplus · Accepted Answer

The use of labels to denote category membership has been found to help children form hierarchical categories. This is because labels provide a clear indication of category membership, giving children a framework for organizing objects into groups. Asking children to categorize people instead of objects (A) may not necessarily improve their ability to form hierarchical categories, as people do not typically form part of a conventional category system. The use of unusual objects (B) may actually hinder a child's ability to form categories, as they may struggle to identify similarities and differences between objects that are unfamiliar to them. The use of a large number of objects (D) may also not necessarily improve a child's ability to form hierarchical categories, as it may overwhelm them and make it more difficult for them to identify category membership.
