Exploring the relevance and relative importance of interpreting aptitude constructs and their underlying factors: A data-driven tripartite investigation

Abstract

AbstractThis study aims to explore the relevance and underlying factors of an array of interpreting aptitude constructs, and, on that basis, the collective and group-specific perception of their relative importance. To meet the research purposes, a questionnaire survey was designed and distributed to interpreting trainers, trainees and professional interpreters, asking respondents to evaluate the relative importance of 40 aptitude constructs drawn from an extensive literature review. A total of 769 valid responses were collected. An explorative factor analysis retained 23 constructs divided into three factors focusing on cognitive skills for online information processing, personality traits and temperaments, and foundational linguistic skills respectively. While personality traits and temperaments were regarded as a stable and distinctive dimension of interpreting aptitude, cognitive skills for information processing were viewed as the most important factor. Particularly, listening and speaking in B enjoyed the highest rating. Although statistically significant differences existed in the relative importance of certain constructs, the substantive differences indicated by the effect sizes were small. Compared with trainees, trainers and professional interpreters demonstrated a more sharpened awareness of market demands and industrial priorities, but otherwise the three groups converged more than they diverged in the evaluation of aptitude constructs and factors.
