Interlanguage Variability in Narrative Discourse: Style Shifting in the Use of the Past Tense

Abstract

This study examines style shifting in the use of three past tense morphemes (regular past, irregular past, and past copula) by 17 intermediate L2 learners of English. It differs from previous studies in that style shifting is examined within a single discourse mode—narrative discourse—according to the amount of planning time made available. Data were collected under three conditions: (a) planned writing, (b) planned speech, and (c) unplanned speech. Different patterns of style shifting were observed for three morphemes, suggesting that the nature of the linguistic feature under investigation is a determining factor. For regular past, greatest accuracy was most evident in planned writing and least evident in unplanned speech, with planned speech intermediate. Little style shifting took place in irregular past, whereas style shifting for past copula occurred only between planned speech and unplanned speech. The three conditions produced different accuracy orders for regular and irregular past, suggesting that the so-called “natural” order may not be a stable phenomenon. The paper concludes with a number of important questions requiring further investigation.
