People are frequently biased to use left-side information more than right-side information to inform their perceptual judgements. This research examined whether the leftward bias also applied to preferences for the arrangement of everyday consumer items. Pairs of consumer items were created where one item was more attractive than the other item. Using a two-alternative forced choice task, Experiment 1 found a robust preference for arrangements with the more attractive consumer item on the left side rather than the right side of a pair. Experiment 2 reversed the judgement decision, with participants asked to choose the arrangement they least preferred, and a bias for arrangements with the more attractive item on the right side emerged. Experiment 3 failed to find an effect of the “attractive left” preference on participants’ purchasing intentions. The preference for attractive left arrangements has implications for the display of consumer products and for the aesthetic arrangement of objects in general. The findings are discussed in relation to hemispheric asymmetries in processing and the role of left to right scanning.

人们经常偏向于使用左侧信息而不是右侧信息来告知他们的感知判断。这项研究调查了向左偏向是否也适用于日常消费品安排的偏好。创建了一对消费项目，其中一个项目比另一个项目更具吸引力。通过采用两种选择的强制选择任务，实验1发现了一种对偏好设置的强烈偏好，其中更具吸引力的消费品位于一对的左侧而不是右侧。实验2颠倒了判断的决定，参与者被要求选择他们最不喜欢的安排，并且在右边出现更具吸引力的项目的安排出现了偏差。实验3未能发现“有吸引力的左”偏好对参与者的购买意愿的影响。偏好有吸引力的左侧布置对消费品的展示和总体上物体的美学布置具有影响。讨论了有关半球形不对称性在处理过程中的发现以及从左到右扫描的作用。
