尽管能够快速准确地推断自己和他人的视觉视角，但当两个视角发生冲突时，健康的成年人很难忽视不相关的视角;他们会经历自我中心和另类中心的干扰。我们第一次研究了被观察者的年龄（成人与儿童化身）如何影响成年人的视觉观点采择，特别是他们从自己或他人的角度体验干扰的程度。参与者完成了化身视觉视角的任务，在其中，他们验证了光盘的数量在一个视觉场景根据自己或屏幕上的化身的角度（实验1和2）或仅从自己的角度（实验3），其中两个角度可以是一致的或冲突。年龄的化身之间（实验1）或（实验2和3）的参与者，和干扰进行了评估，使用行为（实验1-3）和ERP（实验1）的措施。结果显示，当儿童化身存在时，替代干扰减少或消除，这表明成年人不会自动计算儿童化身的视角。我们将这种模式归因于同龄人的视觉处理能力增强或年幼儿童的心理意识降低。研究结果反对一个纯粹的注意力的基础上的alterncentric效果，而是支持一个帐户，其中两个mentalising和方向的过程调节自动视觉透视，透视效果的强烈影响实验环境。
Despite being able to rapidly and accurately infer their own and other peoples’ visual perspectives, healthy adults experience difficulty ignoring the irrelevant perspective when the two perspectives are in conflict; they experience egocentric and altercentric interference. We examine for the first time how the age of an observed person (adult vs. child avatar) influences adults’ visual perspective-taking, particularly the degree to which they experience interference from their own or the other person’s perspective. Participants completed the avatar visual perspective-taking task, in which they verified the number of discs in a visual scene according to either their own or an on-screen avatar’s perspective (Experiments 1 and 2) or only from their own perspective (Experiment 3), where the two perspectives could be consistent or in conflict. Age of avatar was manipulated between (Experiment 1) or within (Experiments 2 and 3) participants, and interference was assessed using behavioral (Experiments 1–3) and ERP (Experiment 1) measures. Results revealed that altercentric interference is reduced or eliminated when a child avatar was present, suggesting that adults do not automatically compute a child avatar’s perspective. We attribute this pattern to either enhanced visual processing for own-age others or an inference on reduced mental awareness in younger children. The findings argue against a purely attentional basis for the altercentric effect, and instead support an account where both mentalising and directional processes modulate automatic visual perspective-taking, and perspective-taking effects are strongly influenced by experimental context.
