Abstract
Previous studies have shown that semantic predictability and semantic relevance enhance the semantic activation of target words and improve memory performance. However, it is unclear whether semantic predictability and semantic relevance affect memory performance through the same neural mechanisms. The present study examined how semantic processing of semantic predictability and semantic relevance during encoding affects episodic memory retrieval. In our experiments (Experiment 1: item recognition; Experiment 2: associative recognition), we compared behavioral and EEG indicators across true (predictable), invalid (unpredictable but semantically relevant), and anomalous (unpredictable and semantically irrelevant) conditions. In both experiments, memory performance was best in the true condition. In Experiment 1, the old/new effect of FN400 was observed in the invalid condition, while the old/new effect of LPC was observed in the true condition. In Experiment 2, the old/new effects of FN400 and LPC were observed in the invalid condition. In the true condition, only the old/new effect of LPC was observed. These results suggest that semantic predictability and semantic relevance influence FN400 and LPC in different ways. These findings demonstrate that there are differences between semantic predictability and semantic relevance in retrieving information.
期刊介绍:
Brain and Cognition is a forum for the integration of the neurosciences and cognitive sciences. B&C publishes peer-reviewed research articles, theoretical papers, case histories that address important theoretical issues, and historical articles into the interaction between cognitive function and brain processes. The focus is on rigorous studies of an empirical or theoretical nature and which make an original contribution to our knowledge about the involvement of the nervous system in cognition. Coverage includes, but is not limited to memory, learning, emotion, perception, movement, music or praxis in relationship to brain structure or function. Published articles will typically address issues relating some aspect of cognitive function to its neurological substrates with clear theoretical import, formulating new hypotheses or refuting previously established hypotheses. Clinical papers are welcome if they raise issues of theoretical importance or concern and shed light on the interaction between brain function and cognitive function. We welcome review articles that clearly contribute a new perspective or integration, beyond summarizing the literature in the field; authors of review articles should make explicit where the contribution lies. We also welcome proposals for special issues on aspects of the relation between cognition and the structure and function of the nervous system. Such proposals can be made directly to the Editor-in-Chief from individuals interested in being guest editors for such collections.
