Investigator Bias in Identification Procedures: Mechanisms and Safeguards

将进行三项研究，以检查调查员偏见何时影响目击者识别的准确性，以及影响准确性的行为。研究一涉及模拟目击证人身份，并操纵管理员的知识。研究二考察了可能影响证人选择嫌疑人的言语和非言语行为。第三项研究考虑了证人对潜在偏颇行政行为的感知。预计调查结果将引起心理和法律界的兴趣，并将对警察阵容的设计产生重大的实际影响，表明哪些保障措施可能有助于确保有效、准确的身份识别。

Three studies will be conducted to examine when investigator bias affects the accuracy of eyewitness identification and the behavior that affects accuracy. Study One involves a simulation of an eyewitness identification, with manipulation of the administrator's knowledge. Study Two examines verbal and non-verbal behaviors that might influence the witness to choose the suspect. The third study considers the witnesses perceptions of potentially biasing administrative behavior. Findings are expected to be of interest to the psychological and legal communities, and to have significant practical implications for the design of police lineups, suggesting what safeguards may help to ensure effective, accurate, identifications.
