How Does Working Memory Capacity Affect the Accuracy of Simultaneous Interpreting

Abstract

Simultaneous interpreting is an intricate and demanding task that requires real-time translation between languages. This complex process involves the interpreter listening to the source language, processing the information, and simultaneously delivering it in the target language. Such a task places considerable demands on cognitive resources, especially working memory, which is crucial for retaining and manipulating information over short periods. This paper delves into the impact of variations in working memory capacity on interpreting accuracy, with particular attention to the cognitive challenges posed by multitasking and managing cognitive load. By synthesizing existing research, the paper explores the connection between working memory capacity and interpreting performance, revealing that interpreters with higher working memory capacity are generally more accurate in their translations. Moreover, the review highlights cognitive strategies like chunking—breaking information into manageable units—and anticipation, which enable interpreters to cope with the substantial cognitive load inherent in simultaneous interpreting. These findings emphasize the vital role of working memory in the interpreting process and suggest that focused training on enhancing cognitive skills could lead to significant improvements in accuracy and efficiency, particularly in high-stakes environments where precision is critical.
