摘　　要：采用辨认后反馈范式研究不同队列呈现方式下反馈对目击证人辨认自信心的影响。结果发现:(1)所有辨认者中,反馈组被试自信心显著高于控制组被试的自信心;反馈方式与辨认选择的交互作用显著,辨认选择与列队呈现方式的交互作用显著;(2)积极辨认者中,反馈组被试的自信心显著高于控制组被试的自信心;正确辨认被试的自信心显著高于错误辨认被试的自信心。结果表明:目击辨认中存在辨认后反馈效应;积极辨认者中辨认自信心可以作为辨认准确性的一个参考指标。Using post-identification approach, we explored the effect of post-identification feedback on eyewitness＇ confidence under two lineup conditions （target-present and target-absent） . Our results indicated that compared to no feedback group, positive feedback increased the confidence of eyewitness＇ identification significantly. Furthermore,among no feedback group, participants making correct identification had greater confidence of identification than participants making false identification, while among positive feedback group, the difference was not significant. Additionally, under incorrect identification condition, target-present lineup resulted in significant increase in confidence of identification, whereas the effect was not significant under correct identification condition. Finally, the eyewitnesses who made a positive identification and receiving positive feedback had greater confidence than participants but not receiving feedback; participants making correct identification had higher confidence than participants making false identification. These findings suggested that there is similar post-identification feedback effect in child and adult eyewitness, and for eyewitness Who made a positive identification, confidence of identification is a predict variable of accuracy.
