The general effects of self-efficacy and explanatory style on performance have been thoroughly researched in the field of psychology. This article is based on Atkinson’s (2012) psychological skill model, which attempts to construct these factors to complement traditional conceptions of interpreter and translator skill, and apply them to interpreter and translator training. This article is a discussion of psychological skill, including factors of self-efficacy, explanatory style, and locus of control, and outlines how self-efficacy and explanatory style can become a focus of interpreter training. Resources to help students conduct self-analysis on their occupational self-efficacy and explanatory style are provided in the appendices, in the form of scales educators can use in their classes. A range of ideas are highlighted to assist students in becoming aware of their psychological skill, and pedagogical suggestions are offered for changing and improving aspects of psychological skill in students.
