A new dopaminergic regulation hypothesis is proposed based on two experiments exploring eye-movement effects. In the Eye Movement Desensitization and Reprocessing (EMDR) and Saccade-Induced Retrieval Enhancement (SIRE) domains, eye-movement mechanisms are mainly studied with explicit measures. Here implicit and explicit measures of emotion and memory for positive and negative pictures were investigated after eye movements or fixation in extreme right-handers. Eye movements enhanced explicit recognition predominantly for negative pictures. The absence of implicit repetition priming in both experiments supported a dissociation between implicit and explicit memory. Motivational eye-movement effects emerged but implicit and explicit affect remained unchanged. Experiment 2 revealed, after initial freezing to negative pictures, an acceleration, particularly of approach responses. Eye movements are postulated to foster approach towards negative memories, and promote, though dopaminergic pathways from the Superior Colliculus, enhanced explicit memory and active emotion regulation, primarily in persons with a collateralization of eye and dopamine dominance.

基于探索眼睛运动效果的两个实验，提出了一种新的多巴胺能调节假说。在眼动脱敏和再处理（EMDR）和扫视诱发检索增强（SIRE）域中，主要通过显式措施研究了眼动机制。在此，在极端的惯用右手的眼睛移动或注视之后，研究了对正面和负面图片的情感和记忆的内隐和外在测量。眼睛运动主要增强了负面图片的显式识别能力。在两个实验中都没有隐式重复启动，这支持了隐式和显式记忆之间的分离。出现了动机性的眼动效应，但内隐和外显的影响保持不变。实验2显示，在最初冻结为负片后，加速了，尤其是进近响应。眼动被认为可以促进消极记忆的发生，并通过上丘C肌的多巴胺能途径促进显性记忆的增强和积极的情绪调节，主要是在具有眼睛和多巴胺优势的人中。
