先前的研究已经证明了情感表达的面孔的知觉后效，但在何种程度上，他们也可以在不同的方式获得是未知的。在两个实验中，我们第一次表明，适应情感，非语言发声elanded显着的听觉后效。适应愤怒的声音会导致来自愤怒-恐惧变形连续体的声音被感知为不那么愤怒和更加恐惧，而适应恐惧的声音会引起相反的后遗症（实验1）。然后，我们通过使用漫画适配器来测试这些后效与潜在声学之间的联系。虽然漫画夸大了发声的声学和情感特性，漫画适配器导致的后遗症，这是与自然发声（实验2）。我们的研究结果表明，这些后效不能仅仅解释为低层次的适应声学特性的适配器，但很可能取决于更高层次的适应神经表征的声乐影响。(C)2010 Elsevier B.

Previous research has demonstrated perceptual aftereffects for emotionally expressive faces, but the extent to which they can also be obtained in a different modality is unknown. In two experiments we show for the first time that adaptation to affective, non-linguistic vocalisations elicits significant auditory aftereffects. Adaptation to angry vocalisations caused voices drawn from an anger-fear morphed continuum to be perceived as less angry and more fearful, while adaptation to fearful vocalisations elicited opposite aftereffects (Experiment 1). We then tested the link between these aftereffects and the underlying acoustics by using caricatured adaptors. Although caricatures exaggerated the acoustical and affective properties of the vocalisations, the caricatured adaptors resulted in aftereffects which were comparable to those obtained with natural vocalisations (Experiment 2). Our findings suggest that these aftereffects cannot be solely explained by low-level adaptation to acoustical characteristics of the adaptors but are likely to depend on higher-level adaptation of neural representations of vocal affect.
