気づきを伴ったタスクの繰り返しが言語知識の手続き化に及ぼす効果

抄録

This study focused on how task repetition influences proceduralization of linguistic knowledge. The participants performed two narrative tasks once a week. All participants were given the same picture stories for the first task and had time to notice errors after the first task. At the second task, the Repetition group (N = 14) was given the same picture story as the first task whereas the No Repetition group (N = 14) was given a different picture story from the first task. One week after Session 4, two posttests were given: posttest 1 with completely new pictures and posttest 2 with the same pictures as the pretest conducted in Session 1. At the posttest 1, the fluency of both groups was similar; however, the No Repetition group spoke less fluently than at the pretest whereas the Repetition group retained their fluency. Furthermore, the Repetition group spoke more accurately than at the pretest whereas the No Repetition group showed no difference. The Repetition group also spoke more accurately than the No Repetition group. At the posttest 2, both groups spoke more fluently and accurately than at the pretest; however, the Repetition group spoke more fluently and accurately than the No Repetition group. This study implies the possible greater effectiveness of task repetition with noticing for facilitating proceduralization rather than no repetition with noticing.
