This paper reports the results of an exploratory cross-sectional study of pragmatic development among three groups of primary school students in Hong Kong who completed a cartoon oral production task (COPT) designed to elicit requests, apologies, and compliment responses. The first two of these speech acts are among the most well represented in the pragmatics literature and are also included in the Hong Kong English language syllabus for primary schools. The latter has also been studied extensively but is not part of the syllabus. Data was collected in Cantonese using the same instrument. Although a number of developmental patterns are revealed—particularly in choice of request strategy, frequency of supportive moves, and use of adjuncts with apologies and compliment responses—there is little evidence of sensitivity to situational variation or pragmatic transfer from Cantonese. This study adds to the small, but growing, body of research on pragmatic development in a second language.
