情绪的负面效价效应最早出现在听觉刺激后20毫秒，二价效应出现在30 - 130毫秒。为了了解情绪状态如何影响听者的脑干对言语的反应，实验对象一边听着不变的听觉刺激，一边看能唤起情绪的图片（danny）。图片（正价、负价或中性价）从IAPS数据库中选择，并控制优势和唤醒。利用一系列测量来评估皮层下调节，我们发现情绪并没有实质性地改变脑干改变，尽管在两种情绪条件下背景噪声抑制都有微妙的影响。
Effects of emotion have been reported as early as 20ms after an auditory stimulus onset for negative valence, and bivalent effects between 30 and 130ms. To understand how emotional state influences the listener's brainstem evoked responses to speech, subjects looked at emotion-evoking pictures while listening to an unchanging auditory stimulus (danny). The pictures (positive, negative, or neutral valence) were selected from the IAPS database and controlled for dominance and arousal. Utilizing an array of measurements to assess subcortical modulation, we have found that emotion does not substantially alter brainstem alter although there is a subtle effect of background noise suppression in both emotional conditions.
