参考排斥是一种机制，被假定用来解释单个漂移点显示器的方向判断的系统偏差（Rauber和Treue，1998 Perception 27 393-402）。Rauber和Treue获得了系统的，但令人惊讶的是，非常不同的效果取决于是否标准和比较刺激同时或连续。连续效应被描述为表现出来自垂直和水平主轴的排斥，而同时效应仅表现出来自水平主轴的排斥。我们认为，所提出的机制没有可测试的预测，因为所谓的参考只能指定后验，一个事实，Rauber和Treue承认。我们试图复制Rauber和Treue的实验，但我们没有获得系统的方向判断偏差。几项研究的比较表明，单一漂移点模式的方向判断错误在幅度和方向上变化很大，这与基线或预测试测量的结果是一致的。在我们看来，参照排斥既没有描述真实的感知机制，也没有描述方向误判的可预测模式。
Reference repulsion is a mechanism posited to explain systematic biases of direction judgment of single drifting dot displays (Rauber and Treue, 1998 Perception 27 393–402). Rauber and Treue obtained systematic but, surprisingly, very different effects depending upon whether standard and comparison stimuli were presented simultaneously or successively. Successive effects were described as exhibiting repulsion from both vertical and horizontal cardinal axes, whereas simultaneous effects showed repulsion from horizontal only. We contend that the proposed mechanism makes no testable predictions because the so-called reference can only be specified a posteriori, a fact acknowledged by Rauber and Treue. We attempted to replicate Rauber and Treue's experiments, but we obtained no systematic biases of direction judgment. Comparisons across several studies suggest that errors in direction judgments of single drifting dot patterns vary widely in magnitude and direction, as might be expected with what are essentially baseline or pretest measures. In our view, reference repulsion describes neither a real perceptual mechanism nor a predictable pattern of direction misjudgments.
