Children combine several gestures in their pretend play at around the same time that they first show two or three-word sentences in their speech. This supports which view of language development?

- The interactionist view.

Explanation:

Language development is demonstrated as the process that is associated with a child's learning of the ability to understand a particular language and communicate in it during the years of early childhood.

The interactionist view offered by Vygotsky of language development states that a child's acquisition of a language is highly determined by the social interactions of the child within the environment. Thus, this view asserts that both these interactions allow children to develop thinking as well as language.

In the given example, the 'use of combined gestures along with the verbal delivery of the speech' exemplify the 'social interaction' through which the children are able to develop cognition and ability to make meaning. Therefore, it follows Vygotsky's social-cultural 'interactionist view' which states the significant role of social interactions in the development of a language and thought in the child.
