我们采用眼动追踪来研究如何在场景中执行不同的任务（例如，有意地记忆它们、搜索对象、评估审美偏好）可以影响编码和随后的场景记忆期间的眼球运动。我们发现，与有意记忆相比，视觉搜索（一个附带的编码任务）后场景记忆力下降，偏好评估（另一个附带的编码任务）产生更好的记忆，类似于先前观察到的单词和面孔的附带记忆提升。通过分析注视图，我们发现，虽然注视图的相似性可以解释如何在视觉搜索过程中的眼动损害附带场景的记忆，它不能解释附带的记忆提升从审美偏好评价，这意味着内隐机制在发挥作用。我们的结论是，并非所有的附带编码任务都应该被认为是相似的，因为不同的机制（例如，显式或隐式）导致不同附带编码任务的记忆增强或减少。
We employed eye-tracking to investigate how performing different tasks on scenes (e.g., intentionally memorizing them, searching for an object, evaluating aesthetic preference) can affect eye movements during encoding and subsequent scene memory. We found that scene memorability decreased after visual search (one incidental encoding task) compared to intentional memorization, and that preference evaluation (another incidental encoding task) produced better memory, similar to the incidental memory boost previously observed for words and faces. By analyzing fixation maps, we found that although fixation map similarity could explain how eye movements during visual search impairs incidental scene memory, it could not explain the incidental memory boost from aesthetic preference evaluation, implying that implicit mechanisms were at play. We conclude that not all incidental encoding tasks should be taken to be similar, as different mechanisms (e.g., explicit or implicit) lead to memory enhancements or decrements for different incidental encoding tasks.
