Emotion influences various cognitive processes, such as memory. This beneficial or detrimental effect can be studied with verbal material, yet in this case a broad term of context has to be taken into account. The present work reviews recent literature and proposes that traditional differentiation between semantic and environmental context should be replaced with a novel conceptualization of hippocampus-dependent relational memory and item memory (related to the activations of cuneus and left amygdala). Additionally, instead of list-learning paradigms, words should be memorized in the context of sentences or stories for better control over their meaning. The recent evidence suggests that of particular importance for ecological validity in research paradigms is the presence of communicative and social context of verbal material related to such processes as theory of mind and brain activations in temporoparietal junction, posterior cingulate cortex, and dorsal medial prefrontal cortex. We propose that studying memory of verbal material within context gives a better understanding of enhancing and impairing effects of emotion as well as of the underlying brain mechanisms.
情绪会影响各种认知过程，比如记忆。这种有益或有害的影响可以通过语言材料来研究，但在这种情况下，必须考虑一个宽泛的情境概念。本研究回顾了近期的文献，并提出，应将海马体依赖的关系记忆和项目记忆（与楔叶和左杏仁核的激活有关）的新颖概念化，取代语义情境和环境情境之间的传统区分。此外，不应采用列表学习范式，而应在句子或故事的情境中记忆单词，以便更好地控制其含义。最近的证据表明，对于研究范式中的生态效度而言，特别重要的是与心理理论以及颞顶联合区、后扣带回皮质和背内侧前额叶皮质中的大脑激活等过程相关的语言材料的交流和社会情境的存在。我们认为，在情境中研究语言材料的记忆，能更好地理解情绪的增强和损害作用以及潜在的大脑机制。
