采用重复测量（重测条件）设计，在二维（效价和唤醒）情绪空间上收集四首音乐所表达的连续自我报告情绪。测试了初始定向时间（IOT）、重测可靠性和余辉。IOT的中位数为8秒。效价评定花了25秒（中值4秒），唤醒则花了35秒（中值12秒）。较慢的速度似乎需要更长的物联网时间。测试-重测信度检验了相关系数，并比较了每个样本在测试和重测条件之间的响应良好一致性的周期。无论反应维度如何，约80%的回答在测试和重测条件下都是可靠的。皮尔逊相关性表明，唤醒反应的重测信度优于效价。复测条件评分在参与者测试条件评分的8%以内。各维度、刺激和条件的平均标准偏差为评分量表范围的12.2%。余辉效应——乐曲结束后乐谱分布的巨大异常值——被确定。因此，连续情绪反应的可靠性被认为是相当好的，但如何处理连续情绪反应数据的开头和结尾必须谨慎。
Continuous self-reported emotion expressed by four pieces of music were collected on a two-dimensional (valence and arousal) emotion space in a repeated measures (test-retest conditions) design. Initial orientation time (IOT), test-retest reliability and afterglow were examined. Median IOT was 8 seconds. Valence ratings took up to 25 (median 4), and for arousal up to 35 (median 12) seconds. Slower tempi seemed to require longer IOT. Test-retest reliability examined correlation coefficients, and compared periods of sample-by-sample good agreement in response between Test and Retest condition. About 80% of responses were reliable in both the Test and Retest conditions regardless of response dimension. Pearson correlations demonstrated better test-retest reliability for arousal responses than for valence. Retest condition ratings were within 8% of Test condition rating within participant. Average standard deviations for ratings collapsed across dimension, stimulus and conditions was 12.2% of the ratings scale range. Afterglow effects – large outliers in spread of scores just after the end of a piece – were identified. The reliability of continuous emotional response is therefore considered to be quite good, but caution must be taken as to how to deal with the opening and ending of continuous emotional response data.
