Abstract

People’s memory for scenes has consequences, including for eyewitness testimony. Negative scenes may lead to a particular memory error, where narrowed scene boundaries lead people to recall being closer to a scene than they were. But boundary restriction—including attenuation of the opposite phenomenon boundary extension—has been difficult to replicate, perhaps because heightened arousal accompanying negative scenes, rather than negative valence itself, drives the effect. Indeed, in Green et al. (2019) arousal alone, conditioned to a particular neutral image category, increased boundary restriction for images in that category. But systematic differences between image categories may have driven these results, irrespective of arousal. Here, we clarify whether boundary restriction stems from the external arousal stimulus or image category differences. Presenting one image category (everyday-objects), half accompanied by arousal (Experiment 1), and presenting both neutral image categories (everyday-objects, nature), without arousal (Experiment 2), resulted in no difference in boundary judgement errors. These findings suggest that image features—including inherent valence, arousal, and complexity—are not sufficient to induce boundary restriction or reduce boundary extension for neutral images, perhaps explaining why boundary restriction is inconsistently demonstrated in the lab.

图像类别和偶然唤醒对边界限制的影响。
人们对场景的记忆会产生影响,包括对目击者证词的影响。负面场景可能会导致一种特殊的记忆错误,即缩小的场景边界会导致人们回忆起自己比实际距离更近的场景。但是边界限制--包括与之相反的边界扩展现象的减弱--一直很难被复制,这也许是因为伴随着负面场景的唤醒增强,而不是负面情绪本身驱动了这种效应。事实上,在Green等人(2019)的研究中,仅以特定中性图像类别为条件的唤醒就会增加对该类别图像的边界限制。但是,图像类别之间的系统性差异可能驱动了这些结果,而与唤醒无关。在这里,我们要澄清边界限制是源于外部唤醒刺激还是图像类别差异。在呈现一个图像类别(日常物品)时,一半伴有唤醒(实验 1),而在呈现两个中性图像类别(日常物品、自然)时,没有唤醒(实验 2),结果是边界判断错误没有差异。这些研究结果表明,图像特征--包括固有情绪、唤醒和复杂性--不足以诱发边界限制或减少中性图像的边界扩展,这或许可以解释为什么边界限制在实验室中的表现并不一致。

期刊介绍: Consciousness and Cognition: An International Journal provides a forum for a natural-science approach to the issues of consciousness, voluntary control, and self. The journal features empirical research (in the form of regular articles and short reports) and theoretical articles. Integrative theoretical and critical literature reviews, and tutorial reviews are also published. The journal aims to be both scientifically rigorous and open to novel contributions.
