在过去的50年里,线索竞争现象已经形成了动物和人类学习的理论发展。然而,最近未能观察到竞争的影响,在标准的条件反射程序,以及长期和持续的争论,周围的线索竞争的空间学习文献,这些现象的普遍性提出了质疑。在本研究中,我们操纵了同时训练的预测因子和结果之间的时间连续性(实验1-4),以及空间学习中地标和目标之间的空间连续性(补充实验1和2;实验5)。在不同的参数变化,我们观察到遮蔽时,时间和空间的连续性强,但没有遮蔽时,连续性弱。因此,在时间和空间域,我们观察到,连续性是必要的竞争发生,并在学习过程中同时呈现的线索之间的竞争是不存在的,当这些线索是空间或时间上不连续的结果。因此,我们提出了一个模型,在该模型中,事件之间的连续性被占,并解释了这些结果,并调和了以前在空间学习中观察到的矛盾发现。
Over the last 50 years, cue competition phenomena have shaped theoretical developments in animal and human learning. However, recent failures to observe competition effects in standard conditioning procedures, as well as the lengthy and ongoing debate surrounding cue competition in the spatial learning literature, have cast doubts on the generality of these phenomena. In the present study, we manipulated temporal contiguity between simultaneously trained predictors and outcomes (Experiments 1–4), and spatial contiguity between landmarks and goals in spatial learning (Supplemental Experiments 1 and 2; Experiment 5). Across different parametric variations, we observed overshadowing when temporal and spatial contiguity were strong, but no overshadowing when contiguity was weak. Thus, across temporal and spatial domains, we observed that contiguity is necessary for competition to occur, and that competition between cues presented simultaneously during learning is absent when these cues were either spatially or temporally discontiguous from the outcome. Consequently, we advance a model in which the contiguity between events is accounted for and which explains these results and reconciles the previously contradictory findings observed in spatial learning.
