摘要

我们的视觉、听觉和触觉不仅取决于我们在特定时刻所处理的东西,还取决于我们最近所感知到的东西。这些顺序效应可能是消极的(排斥)或积极的(同化)。在这里,我们研究了这种顺序效应是否也发生在气味感知中。参与者根据四个不同的特征(强度、熟悉度、效价和唤醒)对40种不同气味(在享乐价上差异很大)进行排序。对于这些特征中的每一个,我们根据前一个试验的评分是高还是低进行了试验间分析。结果我们发现气味强度和熟悉度评级都具有正的序列依赖性。也就是说,当前一项试验的评分高时,当前试验的评分高于前一项试验的评分低时。我们没有观察到气味效价和唤醒等级的顺序效应。结论嗅觉系统将先前的刺激整合到当前的强度和熟悉度感知中。当前的研究结果可能与市场应用相关,并可能指导嗅觉增强虚拟和增强现实系统的设计和使用。

Sequential Effects in Odor Perception

Introduction

Our visual, auditory, and tactile perception is not solely determined by what we process at a given moment in time, but also determined by what we perceived recently. These sequential effects can either be negative (repulsive) or positive (assimilative). Here, we investigated whether such sequential effects also occur in odor perception.

Method

Participants rated a sequence of 40 different odors (varying widely in hedonic valence) on four different characteristics (intensity, familiarity, valence, and arousal). For each of these characteristics, we conducted an inter-trial analysis, based on whether the rating on the preceding trial was low or high.

Results

We found a positive serial dependence for both odor intensity and familiarity ratings. That is, the rating on the current trial was higher when the rating on the previous trial was high than when the rating on the previous trial was low. We observed no sequential effects for odor valence and arousal ratings.

Conclusion

The olfactory system integrates previous stimuli into the current perception of intensity and familiarity.

Implications

The current findings may be relevant for marketing applications and may guide the design and use of olfactory-enhanced virtual and augmented reality systems.
