Associative learning theories offer one account of the way animals and humans assess the relationship between events and adapt their behavior according to resulting expectations. They assume knowledge about event relations is represented in associative networks, which consist of mental representations of cues and outcomes and the associative links that connect them. However, in human causal and contingency learning, many researchers have found that variance in standard learning effects is controlled by "non-associative" factors that are not easily captured by associative models. This has given rise to accounts of learning based on higher-order cognitive processes, some of which reject altogether the notion that humans learn in the manner described by associative networks. Despite the renewed focus on this debate in recent years, few efforts have been made to consider how the operations of associative networks and other cognitive operations could potentially interact in the course of learning. This paper thus explores possible ways in which non-associative knowledge may affect associative learning processes: (1) via changes to stimulus representations, (2) via changes to the translation of the associative expectation into behavior (3) via a shared source of expectation of the outcome that is sensitive to both the strength of associative retrieval and evaluation from non-associative influences.
联想学习理论解释了动物和人类如何评估事件之间的关系,并根据由此产生的期望来调整行为。这些理论假设,关于事件关系的知识以联想网络的形式呈现,该网络由线索和结果的心理表征以及连接它们的联想链接组成。然而,在人类因果关系和偶然性学习中,许多研究人员发现,标准学习效果的差异受“非联想”因素控制,而联想模型难以捕捉这些因素。这引发了基于高阶认知过程的学习理论,其中一些理论完全否定了人类以联想网络所描述的方式进行学习的观点。尽管近年来对这场争论重新给予了关注,但很少有人探讨联想网络的运作与其他认知操作在学习过程中可能如何相互作用。因此,本文探讨了非联想知识可能影响联想学习过程的几种方式:(1)通过改变刺激表征;(2)通过改变联想期望向行为的转化;(3)通过对结果的共同期望来源,该来源对联想检索强度和非联想影响的评估均敏感。
