　　One hundred and forty-four Chinese learners of English participated in the study. They were randomly paired and assigned to either a map task or a picture-story task. Two exemplars of each task type were used on separate occasions （one week apart）. Each task group was further divided into two experimental groupshigh criterion （HC） and low criterion （LC） and a control group. Both the HC and the LC groups were informed at the outset that they would be asked to perform an additional activity upon completion of the baseline task. The HC speakers undertook a more demanding posttask activity， and the LC group a less demanding one. No extra posttask requirement was imposed on the control group. A wide range of measures were employed to evaluate the participants' language production in terms of complexity， accuracy and fluency.
