情绪信息通过空间效价隐喻影响我们的身体体验（积极/消极是上/下）。在本研究中，我们考察了可见和不可见的情绪刺激是否也可以调节自愿行为。在观察了一个情绪图像（例如，积极的、中性的或消极的）之后，参与者使用操纵杆在显示器上任意定位一个点刺激。通过连续闪光抑制技术，即动态眼间掩蔽，对情绪图像进行掩蔽（掩蔽条件）或不掩蔽（未掩蔽条件）。我们发现，在未被遮挡的情况下，观察到的正图像的点的位置明显高于观察到的负图像，而在被遮挡的情况下则不存在这种差异。我们的研究结果表明，有意识的情绪信息对于激活垂直方向的感觉运动表征是必要的，而自愿行为是基于这些激活而进行的。(C) 2015 Elsevier B.V.版权所有
Emotional information influences our bodily experiences according to the space-valence metaphor (positive/negative is up/down). In the present study, we examined whether visible and invisible emotional stimuli could also modulate voluntary action. After observing an emotional image (e.g., positive, neutral, or negative), participants used a joystick to arbitrarily position a dot stimulus in a display. The emotional image was either masked (masked condition) or not (unmasked condition) via a continuous flash suppression technique, i.e., dynamic interocular masking. We found that in the unmasked condition, the placed position of the dot was significantly higher after observing the positive image compared with the negative image, but this difference was not present in the masked condition. Our findings suggest that conscious emotional information is necessary for activating sensorimotor representations of vertical directions, and voluntary action is performed based on these activations.
