刺激发生的环境会影响它的感知。我们使用三全音悖论来研究听音中的语境效应,其中一对复杂的(谢泼德)音调相隔半个八度,可以被感知为上升或下降。虽然在孤立中模棱两可,但在频谱匹配的偏置序列之前,可以听到明显的向上或向下的音高变化。我们将这些有偏见的谢泼德对呈现给清醒的雪貂,并获得初级听觉皮层的神经元反应。利用神经群体反应的降维,我们解码每个音调的感知音高。发现偏置序列可靠地将音调的感知音高从其中心频率移开。利用人类心理物理学,我们提供的证据表明,这种音高的变化也存在于人类的主动感知中。这些结果与谢泼德音调的标准绝对距离解码器不相容,该解码器可以预测吸引音调的偏差。我们提出了一种考虑刺激历史的相对解码器,并与当前和其他数据集保持一致。
The context in which a stimulus occurs can influence its perception. We study contextual effects in audition using the tritone paradox, where a pair of complex (Shepard) tones separated by half an octave can be perceived as ascending or descending. While ambiguous in isolation, they are heard with a clear upward or downward change in pitch, when preceded by spectrally matched biasing sequences. We presented these biased Shepard pairs to awake ferrets and obtained neuronal responses from primary auditory cortex. Using dimensionality reduction from the neural population response, we decode the perceived pitch for each tone. The bias sequence is found to reliably shift the perceived pitch of the tones away from its central frequency. Using human psychophysics, we provide evidence that this shift in pitch is present in active human perception as well. These results are incompatible with the standard absolute distance decoder for Shepard tones, which would have predicted the bias to attract the tones. We propose a relative decoder that takes the stimulus history into account and is consistent with the present and other data sets.
