Previous research has shown that cues that are good predictors of relevant outcomes receive more attention than nonpredictive cues. This attentional bias is thought to stem from the different predictive value of cues. However, because successful performance requires more attention to predictive cues, the bias may be a lingering effect of previous attention to cues (i.e., a selection history effect) instead. Two experiments assessed the contribution of predictive value and selection history to the bias produced by learned predictiveness. In a first task, participants responded to pairs of cues, only one of which predicted the correct response. A second task was superficially very similar, but the correct response was determined randomly on each trial and participants responded based on some physical characteristic of a target stimulus in each compound. Hence, in this latter task, participants had to pay more attention to the target stimuli, but these stimuli were not consistently associated with a specific response. Results revealed no differences in the attentional bias toward the relevant stimuli in the two tasks, suggesting that the bias induced by learned predictiveness is a consequence of deploying more attention to predictive stimuli during training. Thus, predictiveness may not bias attention by itself, adding nothing over and above the effect expected by selection history. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
先前的研究表明,与相关结果有良好预测性的线索比非预测性线索会受到更多关注。这种注意力偏向被认为源于线索的不同预测价值。然而,由于成功的表现需要更多地关注预测性线索,这种偏差可能是先前对线索的注意力(即选择历史效应)的持续影响。两个实验评估了预测价值和选择历史对学习预测性产生的偏差的贡献。在第一个任务中,参与者对线索对做出反应,只有一个线索能预测正确的反应。第二个任务表面上非常相似,但每次试验的正确反应都是随机确定的,参与者根据每个复合刺激的目标刺激的某些物理特征做出反应。因此,在后者的任务中,参与者必须更加关注目标刺激,但这些刺激并不总是与特定的反应相关联。结果表明,两个任务中对相关刺激的注意力偏向没有差异,这表明学习预测性所引起的偏差是在训练期间对预测性刺激投入更多注意力的结果。因此,预测性本身可能不会引起注意力偏向,除了选择历史所预期的效果之外,没有增加任何东西。
