                             Abstract 

	A systematic analysis of the typographical errors of one
skilled female typist led to the identification of a number 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
is thus viewed as having learned to inhibit error tendencies, and
errors such as antedating response and doubling were interpreted in
terms of disinhibition.   

                            Method 

     Over a period of years during the 1960's and 1970's, a female
secretary (E.P.) voluntarily filled time between typing manuscripts by
copytyping selected abstracts onto filing cards.  Her instructions
were that her usual standards of perfectly clean copy were not
necessary because the cards were only to be used for my literature
review project.  She worked on an electric typewriter with a cloth
ribbon that did not duplicate letters if a letter-key was held down.į 

     In scanning this corpus for errors, I attended only to the
body of the abstract, I excluded proper names, numbers, and upper¬case 
acronyms such as UCS and PRE, and I did not count repeat errors 
in the same abstract.  Because of her instructions, even where E.P.
had corrected an error, it was usually possible (95%) to identify the 
error strokes that had been partially erased and then overstruck.
In order to get a reasonable sample of low-frequency errors,
I ultimately set a target of 3,000 keystroke errors.
