Abstract: The paper reports an empirical study comparing the effect of listening input, oral output and written output on high school students’ incidental vocabulary acquisition with the Comprehensible Input Hypothesis and the Comprehensible Output Hypothesis as the theoretical framework. The results show that output tasks can better promote incidental vocabulary learning than listening input task. As far as the output tasks are concerned, retelling have greater influence on the target forms in incidental vocabulary learning than dictation. Therefore, in the future in teaching listening, teachers may integrate different forms of tasks following the input task of listening so that more language forms, with vocabulary in particular, may be learned incidentally for better effect of language development.

Key words: Incidental vocabulary acquisition; input; output hypothesis
