This study examines proposals made during planning talk--a speech act that has received little attention in previous literature--to determine the applicability of the stages of second language (L2) pragmatic development posited by Kasper and Rose (2002). Although Kasper and Rose suggest that formulas play a prominent role in L2 pragmatic development, few studies have considered the applicability of their stages to a non-formulaic speech act. The current study investigated proposal production in the planning talk of 69 participants: 46 learners of Spanish enrolled at five levels of instruction in a seven-week Spanish immersion program, 12 native Spanish speaking instructors in the same program, and 11 native English speaking undergraduate students at the same institution enrolled during the academic year. The L2 learners worked in groups of two or three as they planned three different role-plays during the seventh week of instruction. The native speakers met with the researcher in groups of two or three to complete the same role-plays in their first language (L1). A total of 1809 proposals and 351 supporting moves were produced in approximately four hours of planning talk. Analysis of transcriptions focused on the realization of the head-act strategies, deictic centering, internal and external modification, and the influence of the conversational context on the production of proposals. Results of this cross-sectional analysis suggest that learners do not pass through a formulaic stage when producing proposals in planning talk. The results also suggest that the learners' production of proposals exhibits a u-shaped curve as they adhere to L1 English norms at intermediate levels of proficiency before reflecting L1 Spanish norms at more advanced levels of instruction. L1 English influence was observed in the level of directness of the head-act strategies, the use of deictic centering, internal and external modification, and the influence of the conversational context. Results point to a new framework involving three universal stages of L2 pragmatic development in which L1 influence and pragmatic expansion are more salient.
