FROM A BROAD PERSPECTIVE, THE RESEARCH PROJECT EXAMINED THE BEHAVIORAL EFFECTS OF USING VIDEOTAPE TECHNOLOGY IN COURTROOM TRIAL SITUATIONS. TO INSURE THE VALIDITY AND GENERALIZABILITY OF RESEARCH FINDINGS, SIMULATIONS OF TRIAL PROCEEDINGS USING ACTUAL JURORS VIEWING REAL CASES IN THE PRESENCE OF PROFESSIONAL JUDGES WERE EMPLOYED. THE JURORS BELIEVED THEY WERE TO DELIVER BINDING DECISIONS. ONE TRIAL PROCEEDING DEALT WITH AN AUTOMOBILE INJURY CASE INVOLVING ALLEGED CONTRIBUTORY NEGLIGENCE BY THE PLAINTIFF. THE EFFECTS OF VIDEOTAPE ON VERDICT, AMOUNT OF AWARD, RETENTION OF TRIAL-RELATED INFORMATION, PERCEIVED ATTORNEY CREDIBILITY, PERCEIVED WITNESS CREDIBILITY, JUROR EVALUATION OF DIFFERENT WITNESS TYPES, AND JUROR VERACITY JUDGMENTS OF TESTIMONY WERE EXAMINED. THE USE OF VIDEOTAPE IN THE COURTROOM WAS FOUND NOT TO AFFECT JUROR VERDICTS OR MONETARY AWARDS TO THE PLAINTIFF MADE BY JURORS SIGNIFICANTLY. VIDEOTAPE, HOWEVER, DID AFFECT THE AMOUNT OF TRIAL-RELATED INFORMATION RETAINED BY JURORS DURING THE TRIAL. JUROR PERCEPTIONS OF ATTORNEY CREDIBILITY WERE INFLUENCED BY DIFFERENT EDITING AND PRODUCTION TECHNIQUES, THAT ARE PART OF AVAILABLE VIDEOTAPE TECHNOLOGY, USED TO DELETE INADMISSIBLE EVIDENCE OR TESTIMONY. JUROR PERCEPTIONS OF WITNESS CREDIBILITY WERE AFFECTED BY THE USE OF VIDEOTAPE IN THE COURTROOM, AND VIDEOTAPED PRESENTATIONS OF DIFFERENT TYPES OF WITNESSES AFFECTED JUROR EVALUATIONS OF WITNESS CREDIBILITY. THE PLAINTIFF'S WITNESS WAS MORE EFFECTIVE IN OBTAINING FAVORABLE AWARDS WHEN HE APPEARED LIVE, WHILE THE DEFENDANT'S WITNESS WAS MORE EFFECTIVE IN REDUCING AWARDS WHEN HE APPEARED ON VIDEOTAPE. WITNESS TESTIMONY PRESENTED BY VIDEOTAPE DID NOT AFFECT JUROR JUDGMENTS OF THE VERACITY OF THE TESTIMONY PRESENTED SIGNIFICANTLY. WITHIN THE CONFINES OF JUROR RESPONSES EXAMINED IN THE COURSE OF THE RESEARCH PROJECT, USING DIFFERENT GROUPS OF JURORS AND DIFFERENT PROCEDURES TO EVALUATE THE EFFECTS OF ALL VARIABLES, NO EVIDENCE INDICATED THAT VIDEOTAPED PRESENTATIONS OF TRIALS AS OPPOSED TO LIVE TRIALS HAVE A NEGATIVE IMPACT ON THE JUROR DECISIONMAKING PROCESS.
