It was hypothesized that perception errors on a task requiring Ss to take different viewpoints could be explained in terms of response bias. Four hundred ten first graders, 421 fifth graders, and 260 undergradutaes' error patterns on 39 board/block adaptations of Piaget's three-mountain task were examined with respect to their front, opposite, and reversed choices of camera position. Front choices or egocentric errors were found, overall, to be independent of grade level. Results from this analysis were consistent with the response bias hypothesis: clearly, making an egocentric error is different from behaving in an egocentric manner.
研究假设，在一项要求被试采取不同视角的任务中出现的认知错误可以用反应偏差来解释。针对皮亚杰三山任务的39种棋盘/积木改编版，研究了410名一年级学生、421名五年级学生和260名本科生在相机位置的正面、对面和反向选择上的错误模式。总体而言，正面选择或自我中心错误与年级水平无关。该分析结果与反应偏差假设一致：显然，犯自我中心错误与以自我中心方式行事是不同的。
