报告内容摘要：
Language learning inevitably involves practice and repetition, but learners may find rote repetition mundane. It is often a challenge to design L2 learning tasks that can be repeated in a meaningful and interesting way. A second challenge in task repetition lies in determining the optimal intervals between two repeated tasks (the spacing effects). This study aimed to explore meaningful task repetition (TR) under five performance conditions with different intervals between the initial and repeated performance. Seventy-one adult learners of English as a second language performed a picture description task and, in their randomly assigned groups, repeated the same, unanticipated task with either no interval (immediate repetition), a one-day, three-day, one-week, or two-week interval. Performance was assessed using a range of measures which capture the three dimensions of complexity, accuracy, and fluency (CAF).Results showed that, overall, TR had a positive effect on L2 performance regardless of the length of intervals. Spacing appeared to mediate the effects of TR in terms of fluency and structural complexity, with speed fluencybefittingmost from immediate or small intervals between initial and repeated performances. Structural complexity and repair fluency scores were higher with an interval of one week between performances.
