The main purpose of this study was to examine whether we could find a color bizarreness effect in object memory. Given robust results that objects with bizarre shapes are remembered better than those with common shapes, we would also expect to find a color bizarreness effect. In experiment 1, as in most studies of bizarreness effects, participants were presented pictures one by one in the learning phase, and recalled the object names in the test phase. In experiment 2, we presented multiple objects simultaneously in the learning phase and measured how long participants looked at each object by eye tracking. If participants paid attention to bizarre color objects, it would provide strong support for a color bizarreness effect. The results supported the existence of this effect. Our results strengthen research findings on bizarreness effects in pictorial materials in a different aspect. Not only an object's shape, but also its color can produce the bizarreness effect. Furthermore, we clearly demonstrated that bizarre colors attract attention and enhance object memory. This could be applied to making memorable advertisements and creating learning materials.

物体记忆中的颜色奇异效应：来自回忆测试和眼动追踪的证据

这项研究的主要目的是检查我们是否可以在对象记忆中发现颜色奇异效应。鉴于具有奇异形状的物体比具有普通形状的物体更容易记住的稳健结果，我们还希望找到颜色奇异效应。在实验1中，与大多数奇异效应研究一样，参与者在学习阶段被一张一张地呈现图片，并在测试阶段回忆对象名称。在实验 2 中，我们在学习阶段同时呈现多个物体，并通过眼动追踪测量参与者注视每个物体的时间。如果参与者关注奇异的颜色物体，就会为颜色奇异效应提供强有力的支持。结果支持这种效应的存在。我们的研究结果在不同方面加强了对图片材料奇异效应的研究结果。不仅物体的形状，它的颜色也会产生奇异的效果。此外，我们清楚地证明了奇异的颜色会吸引注意力并增强物体记忆。这可以应用于制作令人难忘的广告和制作学习材料。
