Sentence acceptability experiments have become increasingly common since Cowart (1997) first presented a detailed method for carrying them out, but there is still relatively little clarity among syntacticians about what goes into a well-designed experiment, how to perform one and interpret the results, and why one might want to do this in the first place. This chapter addresses these concerns, by providing recommendations and perspective on how experimental approaches to acceptability can be understood and put to use. Section 1.1 discusses the notion of acceptability in general and the role that it has played in linguistic research. Section 1.2 enters into the details of experimental design, giving an overview of the best practices in acceptability experiments that have emerged from the last two decades of research. Section 1.3 explores the variety of factors, both grammatical and extra-grammatical, that acceptability experiments seem to be able to detect, while Section 1.4 addresses the question of why one might undertake the effort of conducting acceptability experiments.
AcceptabilityAny description of a language inevitably includes a description of what is possible, e.g., a listing of the phonemes, the allowable syllable structures, the preferred word order, etc. These are essentially descriptions of what is "acceptable" in the language, and such descriptions form the core of grammatical research in all traditions. By characterizing what is acceptable, such descriptions also make implicit claims about what is not acceptable. More explicit claims of unacceptability were occasionally included I am grateful to the members of the Experimental Syntax Lab at UC San Diego and to research assistants Chengrui Zheng and Noah Hermansen for their valuable comments, discussion, and assistance in the preparation of this chapter. https://www.cambridge.org/core/terms.
