Difference between "Display" and "Referential" questions

"Display" questions and "Referential" questions are two types of questions used in language acquisition research to assess a child's understanding of language and their ability to communicate effectively. These terms were coined by linguist Brian MacWhinney to describe different types of questions used in language assessment tasks.

Display Questions: Display questions are designed to test a child's knowledge and ability to label or identify objects or pictures. They typically involve pointing to objects or pictures and asking the child to name or describe them. For example, a display question could be asking a child, "What is this?" while pointing to a picture of a dog. The focus is on the child's ability to recognize and label the object correctly.

Referential Questions: Referential questions, on the other hand, are used to test a child's ability to understand and produce language in a more communicative context. These questions require the child to provide information beyond simple labelling. Referential questions typically involve asking the child to describe or explain something, or to provide information about an event or situation. For example, a referential question could be asking a child, "What did you do at the park yesterday?" The focus is on the child's ability to comprehend and produce language in a meaningful and contextually relevant way.

In summary, display questions focus on labelling or identifying objects, while referential questions require the child to understand and use language in a more communicative and meaningful manner. Both types of questions play a role in assessing language development and proficiency in children.
