In the present study we investigated the impact of viscero-sensory feedback on memory performance. Participants with good and poor perception of their heart activity were presented with positive, negative and neutral words while heart rate and skin conductance were measured. After a distractor task, participants were asked to complete primed and unprimed wordstems. Implicit memory performance was assessed in terms of accuracy of completion. In our study, participants with good cardiac perception completed significantly more wordstems of previously presented positive and negative words, whereas no group differences were found for wordstems of neutral words and physiological measures during encoding. Our findings document a substantial role of visceral feedback in implicit memory processes. They are in line with Damasio's somatic marker hypothesis stating that access to information about somatic processes facilitates cognitive processing.
在本研究中，我们研究了内脏感觉反馈对记忆表现的影响。参与者在感知自身心脏活动的好坏的情况下，接受积极、消极和中性的单词，同时测量心率和皮肤电导。在分心任务之后，参与者被要求完成启动和未启动的单词词干。以完成的准确性来评估内隐记忆表现。在我们的研究中，具有良好心脏感知的参与者完成了先前呈现的积极和消极单词的更多单词词干，而在中性单词的词干和编码期间的生理测量方面没有发现组间差异。我们的发现证明了内脏反馈在内隐记忆过程中起着重要作用。它们与达马西奥的躯体标记假说一致，该假说指出，获取有关躯体过程的信息可以促进认知处理。
