众多的理论和药理学论据导致焦虑和记忆是两个密切相关的概念的假设。然而，对这种关系的研究充满了复杂性，因为记忆和焦虑都不是单一的现象。事实上，术语记忆涵盖了大量的概念，焦虑被分为两大类，“状态”焦虑和“特质”焦虑。最近，Balb/c小鼠面对自由探索范式时表现出的新恐惧反应被认为是一种“特质焦虑”模型，而在亮/暗选择过程中表现出的反应被认为是一种“状态焦虑”模型。本研究的目的是进一步阐明这两种焦虑类型和被动回避测试中评估的情绪事件记忆之间的联系。通过主成分分析评估了这三个测试中测量的变量之间的关系，证实了两个焦虑测试中记录的行为并不反映相同的心理状态，并表明情绪记忆与“状态”有关，但与“特质”焦虑无关。
Numerous theoretical as well as pharmacological arguments lead to the assumption that anxiety and memory are two closely linked concepts. Nevertheless, the study of this relationship is full of complexities because neither memory nor anxiety are unitary phenomena. Indeed, the term memory covers a large number of concepts, and anxiety has been divided in two main classes, ''state'' and ''trait'' anxiety. Recently the neophobic responses exhibited by Balb/c mice confronted to the free exploratory paradigm have been proposed as a ''trait anxiety'' model while response exhibited in the light/dark choice procedure as a ''state anxiety'' one. The aim of this study was to further clarify the link between these two anxiety types and memory of emotional events assessed in the passive avoidance test. The relationship between the variables measured in these three tests were assessed by a principal component analysis that confirmed that the behavior recorded in the two anxiety tests does not reflect the same psychological state, and showed that emotional memory is linked to ''state'' but not ''trait'' anxiety.
