人们会将“右”和“左”与积极或消极的事物相关联,这称为左右空间的情感效价。以具身认知理论和躯体特异性假设为基础的研究发现,右利手会将右侧空间与积极事物相关联,而左利手则会将左侧空间与积极事物相关连;左右空间情感效价是由利手与非利手的运动经验塑造的;利手与非利手运动经验的改变则会反转左右空间情感效价;趋近动机脑功能偏侧化与利手是一致的。未来的研究应进一步澄清利手运动与趋近动机在神经机制上的关联性,并探索文化因素与身体经验如何共同塑造左右空间情感效价。
Good things and bad things are often associated with the right or the left, which is the affective valence of left space and right space. The studies basing on theories of embodied cognition and body-specificity hypothesis show that right-handers implicitly associate "good" with "right" and the opposite is true for left-handers. The motor experience of dominant hand and nondominant hand shape space valence. Space valence can be reversed as a result of changes in motor experience of dominant hand and nondominant hand. The brain areas that support approach motivation functionally are related to areas that support motor actions of dominant hand. Future research should focus on the relationship between the laterality of motivation and the laterality of manual motor control and determine how influences of cultural and bodily experiences combine to shape space valence.
