This study compared two technical sign movie formats, Quicktime (2D) and threedimentional animations (3D) and examined recall, comprehension, and rehearsal time of signs. There was no significant difference found between the formats for comprehension and recall. However, for rehearsal the high school students had significantly higher sign production scores after viewing 2D signs as comparaed to 3D signs. In addition, there was a significant difference found relating to gender. Girls scored significantly higher on all three measures, regardless of the movie format. In addition, students with more than two years experience with ASL scored significantly higher than those with less than two years on both recall and comprehension using both movie formats. Implications of these findings will be discussed in this paper.
