Abstract. The Cambridge Face Memory Test Long (CFMT+) and the Glasgow Face Matching Test Short (GFMT-S) are frequently used tests in face recognition research. No test-retest results in conjunction with internal consistency, mean inter-item correlations (MICs), and pre-post mean differences have been reported. The internal consistency and the MICs provide insights into the homogeneity of items. In an online study ( N = 72), we investigated the test-retest reliability, Cronbach’s α, split-half reliability, MICs, and retest mean differences for the CFMT+ and the GFMT-S. The CFMT+ showed satisfactory reliability coefficients above .88, whereas the coefficients of the GFMT-S were mainly dissatisfactory and below .75. We argue that task characteristics like heterogeneous stimulus material might lower MICs, response behavior might enhance reliability, and practice effects might increase the means of the CFMT+ in repeated measurements. Therefore, an integrative evaluation of different psychometric parameters helps explaining variations of reliability in face recognition tests.

人脸记忆和人脸匹配

摘要。Cambridge Face Memory Test Long (CFMT+) 和 Glasgow Face Matching Test Short (GFMT-S) 是人脸识别研究中经常使用的测试。没有报告与内部一致性、平均项目间相关性 (MIC) 和前后平均差异相结合的重测结果。内部一致性和 MIC 提供了对项目同质性的洞察。在一项在线研究 (N = 72) 中，我们调查了 CFMT+ 和 GFMT-S 的重测信度、Cronbach's α、分半信度、MIC 和重测平均差。CFMT+ 显示令人满意的可靠性系数高于 0.88，而 GFMT-S 的系数主要不令人满意且低于 0.75。我们认为，异质刺激材料等任务特征可能会降低 MIC，反应行为可能会提高可靠性，和实践效果可能会增加 CFMT+ 在重复测量中的均值。因此，对不同心理测量参数的综合评估有助于解释人脸识别测试中可靠性的变化。
