The present study investigated the perceived credibility of an eyewitness as a function of the grammar he uses on the stand, as well as the way in which his testimony is presented (written or videotaped format) to mock jurors. Fifty students, 19 males and 31 females, from Kutztown University participated in the study. Ages of the subjects ranged from 18 to 42 with a mean age of 21.94. Subjects were asked to read an exchange of dialogue between two lawyers, a defendant, and a plaintiff. Dialogue was taken, in part, from Levy (1950). Subjects either read or watched a videotape of an eyewitness who used either correct or incorrect grammar on the stand, according to condition. Significant main effects were found for grammar (p<.05) with higher credibility ratings being awarded to an eyewitness who used correct grammar on the stand.
