Do modern natural language processing (NLP) models exhibit human-like language processing? How can they be made more human-like? These questions are motivated by psycholinguistic studies for understanding human language processing as well as engineering efforts. In this study, we demonstrate the discrepancies in context access between modern neural language models (LMs) and humans in incremental sentence processing. Additional context limitation was needed to make LMs better simulate human reading behavior. Our analyses also showed that human-LM gaps in memory access are associated with specific syntactic constructions; incorporating additional syntactic factors into LMs' context access could enhance their cognitive plausibility.
