Without an understanding of the impact of sexual violence on a person, the victim’s behavior, such as wavering cooperation, avoidance of questions, or nervousness, could indicate to an untrained observer that the person may not be telling the truth, which can be a critical conclusion in he said/she said situations. To someone trained in what to expect from trauma victims, this behavior is better understood as related to the trauma and may be evaluated more objectively in determining a person’s credibility.
