The purpose of the study was to determine the effect of various types of visual information on the listening comprehension of English. A 2 x 3 factorial design was used to examine the effects of two independent variables. The material genre variable consisted of two levels: (1) documentaries, (2) lectures and interviews. The visual information type variable consisted of three levels: (1) motion video, (2) still images, (3) no visual information. A total of 63 Japanese college students participated in the experiments as subjects. Comprehension of the material was measured by a test of 20 open- ended questions conducted immediately after the subjects listened to the materials. The results support the hypotheses that (1) presentation of visual information increases the subjects' comprehension of the materials, (2) motion video imagery improves the comprehensibility of documentaries more than still images do, while (3) materials such as lectures and interviews with still photographic images are as comprehensible as those with moving video imagery, and (4) the effect of visual aids on listening comprehension varies depending on the learners' listening levels and comprehension question types.
