This paper calls attention to an increasingly prominent field of interest within second language acquisition research and pedagogy, namely, that of pragmatic ability. It focuses on an area within pragmatics, that of speech acts, considers the processes underlying the performance of such speech acts, and looks at the effects of explicit instruction in this area. The paper starts by asking what speech act ability entails. Several basic distinctions are made in the description of speech acts, such as that between sociocultural and sociolinguistic ability. Second, directions of previous research describing speech acts are indicated and directions yet to be taken are pointed out. Difficulties in researching oral speech act performance are noted, and verbal report is recognized as one of a limited number of research tools available for investigating cognitive processes involved in speech act production. The paper then reviews four studies that utilize verbal report to gain at least some access to the underlying processes. Finally, the paper looks at previous research on the tutored and untutored acquisition of speech acts and provides suggestions for future research.
