What are good control stimuli for music perception research? Systematic evaluations of control suitability remain limited. We wanted to examine if control stimuli (brown, pink, white noise, and voice recordings) lead to different emotional ratings in themselves.
Across two separate studies (n = 84, and 1280, respectively), participants assessed brown, pink, and white noise and voice recordings using a music-emotional perception scale with variations. We used the GEMS-9 scale, and the GEMS-9 scale with the second-order factors 'sublime', 'uneasy', and 'vital'.
Our two studies show that brown noise was considered more sublime than white and pink noise, while white noise was considered more uneasy than brown noise, pink noise, and voice recordings in both studies.
Brown, pink, and white noise is rated emotionally above 3 on unease on a scale from 1 to 7. This means that none of the noise stimuli had minimal emotional ratings and therefore had an emotional effect in themselves. Out of the three noise stimuli, white noise had the highest ratings of unease across both studies. Only voice recordings were considered neutral, defined as having consistently minimal emotional ratings in both studies.
音乐感知研究中，哪些是合适的对照刺激？对对照适用性的系统评估仍然有限。我们想研究对照刺激（棕色噪声、粉红噪声、白噪声和语音录音）本身是否会导致不同的情绪评分。
在两项独立研究中（分别为n = 84和n = 1280），参与者使用带有不同变体的音乐情绪感知量表对棕色噪声、粉红噪声、白噪声和语音录音进行评估。我们使用了GEMS - 9量表以及带有二阶因素“崇高”“不安”和“活力”的GEMS - 9量表。
我们的两项研究表明，在两项研究中，棕色噪声比白噪声和粉红噪声被认为更具崇高感，而白噪声比棕色噪声、粉红噪声和语音录音被认为更令人不安。
在1到7的量表上，棕色噪声、粉红噪声和白噪声在不安程度上的情绪评分均高于3。这意味着没有一种噪声刺激的情绪评分极低，因此它们本身都有情绪影响。在这三种噪声刺激中，白噪声在两项研究中的不安评分最高。只有语音录音被认为是中性的，即在两项研究中情绪评分始终极低。
