Previous studies have demonstrated a retardation in the rate of novel learning about previously blocked cues as compared to appropriate control cues. We report an experiment investigating whether this retardation in novel learning about a blocked cue is accompanied by a reduction in attention to this cue, as anticipated by attentional theories of associative learning. Consistent with these theories, eye gaze measures revealed a reduction in overt attention to the blocked cue both during the compound training phase of the blocking procedure, and also during novel learning with respect to new outcomes. Moreover, the extent of the bias in overt attention away from blocked cues was positively correlated with the subsequent reduction in rate of novel learning about these cues.
以往的研究表明，与适当的对照线索相比，对先前被阻断线索的新学习速率会出现延迟。我们报告了一项实验，该实验旨在研究对被阻断线索的新学习延迟是否伴随着对该线索注意力的降低，这是联想学习的注意力理论所预期的。与这些理论一致，眼动注视测量结果显示，在阻断程序的复合训练阶段以及关于新结果的新学习阶段，对被阻断线索的明显注意力均有所降低。此外，明显注意力从被阻断线索上转移的偏差程度与随后对这些线索新学习速率的降低呈正相关。
