The book presents a study into the trainee interpreters' and certified interpreters' subjective experience of psycho-affective factors in consecutive interpreting. In the form of four case studies, the book offers an insight in how the subjective experience of anxiety, fear, language ego/language inhibition/language boundaries, extroversion/introversion, self-esteem, motivation and stress conditions and affects consecutive interpreting performance. What emerges from the study is that the interpreter's psycho-affectivity is a continually operating and intricate mechanism which may impact on nearly all constituents of the consecutive interpreting process and that its potential causes may lie in virtually all even the seemingly unimportant aspects of the interpreting process.
