Prior studies have shown that a left-right spatial compatibility effect occurs for vertically oriented stimuli relative to a background context of a face rotated 90° clockwise or counterclockwise from upright. For stimuli presented at the location of the eyes, the mapping of the right eye to a right response and the left eye to a left response, as would be viewed by the participant, yields better performance than does the opposite mapping. An issue of current interest in social cognition is whether animate objects are processed differently from inanimate ones. We investigated this issue in two experiments in which we compared the compatibility effects obtained with inanimate objects to those obtained with animate, face stimuli. The results showed left-right compatibility effects from the participant's perspective for vehicles and faces from frontal and profile views, as well as for a road sign. Our findings indicate that coding of stimulus location relative to an external frame of reference is not restricted to face backgrounds.
先前的研究表明，相对于从直立状态顺时针或逆时针旋转90°的面部背景而言，对于垂直方向的刺激会出现左右空间兼容性效应。对于呈现于眼睛位置的刺激，从参与者的视角来看，右眼对应右反应、左眼对应左反应的映射比相反的映射产生更好的表现。社会认知中当前感兴趣的一个问题是有生命物体与无生命物体的处理方式是否不同。我们在两项实验中研究了这个问题，在实验中我们将无生命物体获得的兼容性效应与有生命的面部刺激获得的兼容性效应进行了比较。结果显示，从参与者的视角来看，对于车辆以及正面和侧面视图的面部，还有一个路标，都存在左右兼容性效应。我们的研究结果表明，相对于外部参照框架的刺激位置编码并不局限于面部背景。
