Human Factors Studies on Error Chains

Abstract

The study of error chains is an important area of research from the perspectives of basic human factors and the prevention of critical accidents. In this article, an error chain is defined as a phenomenon in which an initial error causes changes in emotion or cognition, which in turn leads to a subsequent error. Numerous studies have examined the latter half of the error chain—that is, how emotional or cognitive changes influence the occurrence of errors. However, relatively few studies have focused on the initial half of the error chain, which explores how the first error induces emotional or cognitive changes. To comprehensively understand error chains, it is necessary to increase research on the chain’s initial half and integrate findings from both halves. Furthermore, in experimental studies on error chains, it is essential to control the occurrence of errors adequately. Addressing these challenges is expected to advance the study of error chains.
