20名正常受试者暴露于两个系列的两种不同的载玻片，随机与休克的发生或不发生配对。 第一个系列开始时，一个幻灯片与休克（“目标幻灯片”）的配对数量比另一个要多，以诱导一种虚幻的相关性（IC）。 同时，在所有试验中，两种载玻片的电击/载玻片偶然性相等。 在第二个系列中，一个真正的随机序列的滑动冲击试验，以检查是否IC是抵抗disconfirmational信息。 受试者的权变估计记录后验以及在线。 此外，皮肤电反应记录在一个试验的基础上。 数据表明，它是可能的，以诱导一个中性刺激和一个厌恶的结果之间的条件反射一样的程序。 此外，数据强烈表明，IC可以采取行动，以维持或增强协变偏差的指数由在线概率估计。 最后，数据支持的假设，协变偏差与差分自主反应。
Twenty normal subjects were exposed to two series of two different slides randomly paired with the occurrence or non-occurrence of shock. The first series started with a greater number of pairings of one slide with shock ("target slide") than the other to induce an illusory correlation (IC). Meanwhile, across all trials shock/slide contingency was equal for both slides. During the second series, a truly random sequence of slide-shock trials was used in order to examine whether IC was resistant to disconfirmational information. Subjects' contingency estimates were recorded a posteriori as well as on-line. In addition, electrodermal responding was recorded on a trial-by-trial basis. Data show that it is possible to induce an IC between a neutral stimulus and an aversive outcome by means of a conditioning-like procedure. Moreover, data strongly suggest that an IC can act in such a way as to maintain or enhance covariation bias as indexed by on-line probability estimates. Finally, data sustain the hypothesis that a covariation bias is associated with differential autonomic responding.
