传统上,感知被认为是一个封装的过程,不受情感等自上而下的过程的影响。最近的视觉研究工作表明,感知者情绪状态的变化会影响视觉感知的许多不同方面,从而对这一框架提出了质疑。在这里,我们将情感和感知之间的关系扩展到另一种感知方式:听觉。参与者通过写下过去的可怕或中性经历而陷入消极或中性情绪。然后,他们聆听一系列短而中性的音调(320 和 640 毫秒),并对音调的响度和持续时间进行评级。消极情绪的参与者认为音调明显比中性情绪的参与者响亮,但不是更长,这表明两组之间的差异是感知上的,而不仅仅是反应偏差。这项研究首次表明,情感在知觉过程中的作用可能比以前认为的更为普遍。
Traditionally, perception was considered to be an encapsulated process that was unaffected by top-down processes like affect. Recent work in vision draws this framework into question by showing that changes in the emotional state of the perceiver can impact many different aspects of visual perception. Here, we extend the relationship between affect and perception into another perceptual modality: audition. Participants were induced into a negative or neutral mood by writing about a frightening or neutral experience in their past. They then listened to a series of short, neutral tones (320 and 640 ms) and rated the loudness and duration of the tones. Participants in a negative mood rated the tones as significantly louder, but not longer, than participants in a neutral mood, suggesting that the difference between the groups was perceptual rather than just a response bias. This research shows for the first time that the role of affect in perceptual processes may be more pervasive than previously considered.
