The Concealed Information Test (CIT) aims to detect the presence of crime-related information in memory. In two experiments, we examined the influence of stimulus emotionality on the outcomes of the CIT. In experiment 1, each participant was tested immediately or after one week, on a series of neutral and either negative arousing or negative non-arousing pictures. CIT detection efficiency was unaffected, but physiological and recognition data did not support the manipulation's effectiveness. In experiment 2, each participant was tested after a week on a series of neutral versus negative arousing pictures. Importantly, stimulus arousal was increased and memory ceiling effects were prevented. This time, both memory and CIT detection efficiency using the skin conductance, but not the respiration and heart rate measures, were enhanced for emotional compared to neutral pictures. Taken together, these results indicate that the use of emotional stimuli does not deteriorate and may even improve CIT validity.
隐蔽信息测试测试（（CIT）旨在检测记忆中与犯罪相关信息的存在。在两项实验中，我们研究了刺激情绪对CIT结果的影响。在实验1中，每位参与者在一系列中性图片以及消极唤起或消极非唤起图片上，立即或在一周后接受测试。CIT检测效率未受影响，但生理和识别数据不支持该操作的有效性。在实验2中，每位参与者在一周后在一系列中性图片与消极唤起图片上接受测试。重要的是，刺激唤起增强且记忆上限效应得到防止。这一次，与中性图片相比，使用皮肤电导率（而非呼吸和心率测量）的记忆和CIT检测效率在情绪图片上均得到提高。综上所述，这些结果表明，使用情绪刺激不会降低甚至可能提高CIT的有效性。
