Neuro-scientific basis of affective dimensions derived from semantic differential method

不同对象引起的情感意义可以通过语义差异(SD)技术来量化。在这项技术中，无论对象的差异和参与者的文化差异，都一致地提取了三个主要因素(评估、活动和能力)。利用神经成像(FMRI)，我们发现E、A和P分别在额下回、额上回和额上回产生脑活动。我们的研究是一项开创性的工作，表明情感维度的心理结构分布在大脑的特定区域。

Affective meanings aroused by various objects can be quantified by the semantic differential (SD)technique. In this technique, 3 main factors ("Evaluation","Activity", and"potency")have been consistently extracted irrespective of the differences in objects and the cultural differences of participants. Using neuro-imaging (fMRI), we showed that E, A, and P produced brain activities in the inferior frontal gyrus, the superior temporal gyrus, and the superior frontal gyrus, respectively. Our research is a pioneer work that suggests the psychological structures of affective dimensions being distributed in specific areas of the brain.
