Visual perspective (first-person vs. third-person) is a salient characteristic of memory and mental imagery with important cognitive and behavioural consequences. Most work on visual perspective treats it as a unidimensional construct. However, third-person perspective can have opposite effects on emotion and motivation, sometimes intensifying these and other times acting as a distancing mechanism, as in PTSD. For this reason among others, we propose that visual perspective in memory and mental imagery is best understood as varying along two dimensions: first, the degree to which first-person perspective predominates in the episodic imagery, and second, the degree to which the self is visually salient from a third-person perspective. We show that, in episodic future thinking, these are anticorrelated but non-redundant. These results further our basic understanding of the potent but divergent effects visual perspective has on emotion and motivation, both in everyday life and in psychiatric conditions.
视觉视角（第一人称视角与第三人与第三人称视角）是记忆和心理意象的一个显著特征，具有重要的认知和行为后果。大多数关于视觉视角的研究将其视为一个单维结构。然而，第三人称视角对情绪和动机可能产生相反的影响，有时会强化这些影响，而有时则起到一种疏离机制的作用，如在创伤后应激障碍中。基于诸多原因，我们提出，记忆和心理意象中的视觉视角最好理解为沿两个维度变化：第一，第一人称视角在情景意象中占主导的程度；第二，从第三人称视角看自我在视觉上的显著程度。我们表明，在情景未来思维中，这两个维度呈负相关但并非冗余。这些结果进一步加深了我们对视觉视角在日常生活和精神疾病中对情绪和动机产生的强大但不同影响的基本理解。
