Who are some notable researchers involved in the development of core vocabulary?

The choice highlighting Gail Van Tatenhove and Karen Erikson is correct due to their significant contributions to the field of augmentative and alternative communication (AAC), particularly in the development of core vocabulary. Core vocabulary refers to a set of high-frequency words that are used across various contexts and by many individuals, making it crucial for effective communication, especially for those using AAC devices.

Van Tatenhove and Erikson have collaborated to advance the understanding of core vocabulary's importance in AAC interventions, enabling practitioners to support individuals in developing functional communication skills that can be easily generalized across different situations. Their work often emphasizes the selection and teaching of these essential vocabulary items to enhance communicative competence.

The other researchers mentioned do not have documented contributions specifically tied to core vocabulary in the same prominent way, making the choice of Van Tatenhove and Erikson the most relevant in the context of core vocabulary development.
