An object located in the centre position is believed to be the most attended and well remembered, which increases its likelihood of being chosen (i.e., centrality preference). However, the literature has yielded inconsistent evidence. With the support of an eye-tracking technique, this study tried to provide another means of examining the relationship between preference and attention. Thirty undergraduates were asked to choose one of five similar items presented on a horizontal line. The findings on eye fixation points and looking duration positively related to the probability of an item being chosen as the preferred item. Yet performance in a recall test revealed an independence between preference and remembering. Furthermore, an unexpectedly large proportion of the participants also preferred the items on the leftmost side of the array. The mental number line and social norms, together with centrality preference, were used to provide an explanation of our implicit preference in decision making.

最好的东西总是在中间？通过眼动追踪技术和记忆记忆研究中心性偏好

位于中心位置的对象被认为是最受关注和记住最多的对象，这增加了其被选择的可能性（即，中心性偏好）。但是，文献得出的证据不一致。在眼动追踪技术的支持下，本研究试图提供另一种检查偏好与注意力之间关系的方法。要求30名大学生从水平线上选择的五个类似项目之一。眼睛固定点和注视时间的发现与某项被选为首选项的可能性成正比。然而，在回忆测试中的表现显示出偏好和记忆之间的独立性。此外，出乎意料的很大比例的参与者还更喜欢阵列最左侧的项目。
