本研究旨在确定对刺激值的记忆是否是刺激大小的贝叶斯加权和范例类别的集中趋势（Huttenlocher, Hedges, & Vevea, 2000）。在五个实验中，参与者从两个类别中复制了一个几何图形的记忆大小，这两个类别的大小平均值不同。再生产倾向于组合分布的平均值，而不是任何一个类别的平均值。再生产也受到前一个试验刺激大小的影响。这两个结果都不完全符合这样一种观点，即回忆部分是基于对类别隶属关系建立的长期概率的考虑而构建的。
This study was designed to determine whether memory for stimulus values is a Bayesian weighting of the magnitude of a stimulus and the central tendency of an exemplar's category (Huttenlocher, Hedges, & Vevea, 2000). In five experiments, participants reproduced the remembered size of a geometric figure drawn from one of two categories whose means for size differed. Reproductions were biased toward the mean of the combined distribution rather than the mean of either category Reproductions were also influenced by the size of the stimulus on the preceding trial. Neither of these results is entirely consistent with the view that recollections are partially constructed from a consideration of the long-run probabilities established by category membership.
