研究人员认为，先前关于海马体区域在联想学习中的功能的计算解释（M. Gluck和C. Myers, 1993）具有新的含义，它准确地描述了海马体区域在语境处理中的作用。这篇文章统一了关于语境处理的两种看似矛盾的观点：它没有赋予语境线索特殊的表征地位（例如，R. Rescorla和a . Wagner, 1972），但它也允许语境与其所包含的线索处于一种上级关系（例如，L. Nadel和J. Willner；见记录1981-22862-001）。因此，该理论正确地预测了语境可以发展情境设置属性，语境变化可以削弱习得反应或减弱潜在抑制。这篇文章还解释了表明海马病变降低环境敏感性的数据。它可能有助于统一之前关于海马体区域在情境处理中的作用的几个理论解释。（PsycINFO数据库记录(c) 2016 APA，版权所有）
The researchers argue that a previous computational account of hippocampal region function in associative learning (M. Gluck and C. Myers, 1993) has emergent implications that accurately describe the role of the hippocampal region in contextual processing. This article unifies 2 seemingly conflicting views of contextual processing: It accords contextual cues no special representational status (eg, R. Rescorla and A. Wagner, 1972), yet it also allows context to stand in a superordinate relationship to the cues it contains (eg, L. Nadel and J. Willner; see record 1981-22862-001). As a result, the account correctly expects that context can develop occasion-setting properties and that context shifts can weaken learned responses or attenuate latent inhibition. The article also explains data suggesting that hippocampal lesions reduce contextual sensitivity. It may help unify several previous theoretical accounts of the hippocampal region's role in contextual processing.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
