Inconsistency between nonverbal communication and the content of what is being said detracts from the witnesses' effectiveness. When witnesses express anger or sadness verbally but project a calm demeanor, credibility is lessened. In addition, if the emotion is expressed verbally while the onset of the supporting body movements is delayed, then credibility also is reduced. For maximum effectiveness, verbal and nonverbal communication should be consistent. Prepare witnesses for the experience of examination.
Witnesses can benefit in the preparation process by going through a dry run of their testimony.
Conducting the mock examination in a courtroom setting is ideal for preparing witnesses for their trial experience. However, conducting the examination in an office or conference room still will afford witnesses an opportunity to reduce their anxiety and nervousness associated with trial testimony. In conducting the mock examination, care should be given to conduct the questioning in as formal a manner as possible. A location that promotes a formal atmosphere should be sought. The attorney should make clear to the witness the formal nature of the examination.
