This chapter deals with two common elicitation procedures in second language acquisition (judgment tasks and elicited imitation). The chapter begins with a discussion of the uses and misuses of judgment data. The major focus is on the practicalities involved in collecting acceptability/grammaticality judgment data, although mention is also made of other types of judgment data (e.g., truth-value judgments) and an alternative to judgment data, namely, magnitude estimation. This section is followed by looking at elicited imitation. The chapter then addresses earlier controversies in using these data and elucidates best practices.
