Aphasia is an acquired language disorder most often caused by stroke. Word retrieval impairments (anomia) predominate all types of aphasia, which can significantly impact a person’s ability to convey his or her thoughts and emotions. Verb Network Strengthening Treatment (VNeST) is an aphasia intervention that aims to promote increased word retrieval within sentences and discourse (e.g., telling a story) that are not explicitly trained (i.e., generalization) in an effort to facilitate more effective communication.

Historical Background

Because VNeST attempts to recruit and strengthen various aspects of language, it is related to a number of treatment approaches. VNeST is fundamentally a semantic treatment, since it requires participants to retrieve words (thematic roles) related to a given verb (e.g., a pilot (agent) flies (verbs) a helicopter(patient)). Semantic feature analysis (SFA), a precursor to VNeST, also requires semantic search and retrieval around target words,...
