Inconsistent findings regarding the valence hypothesis might relate to ambiguously valenced stimuli used in some studies. To account for this potential caveat, we used positive and negative attachment words. A total of 50 participants made lexical decisions in a bilateral simultaneous presentation paradigm. Results showed a general right-visual-field advantage for lexical decisions and a general superiority for positive over negative words. Crucially, we found a left-visual-field advantage for positive over negative words. Results oppose the valence hypothesis, but support a specific role of the right hemisphere in emotional processing, in particular when dealing with positive interpersonal relationship information.
关于效价假设的不一致发现可能与一些研究中使用的效价模糊的刺激有关。为了解决这一潜在问题，我们使用了积极和消极的依恋词汇。共有50名参与者在双侧同时呈现范式中进行词汇判断。结果显示，词汇判断总体上存在右视野优势，且积极词汇相对于消极词汇总体上更具优势。至关重要的是，我们发现积极词汇相对于消极词汇存在左视野优势。这些结果与效价假设相悖，但支持右半球在情绪加工中发挥特定作用，特别是在处理积极人际关系信息时。
