| Abstract: | An analysis of the errors made by a skilled female typist led to the identification of error factors that often act conjointly. Substitution errors indicated that she had acquired a cognitive map of the keyboard and then controlled her fingers by spelling the to-be-typed words covertly. Accordingly, some typographical errors were attributed in part to errors of inner speech. Intrusion errors revealed both habit factors and a response perseveration tendency. A handedness effect and omission errors indicated response error factors, and transpositions indicated temporal error factors. The skilled typist was thus viewed as having learned to inhibit error tendencies, and errors such as antedating response and doubling were interpreted in terms of disinhibition.
