“This paper investigates the impact of different levels of expertise on errors in human-computer interaction. In a field study 174 clerical workers from 12 different companies were observed during their normal office work and were questioned on their expertise with computers. The level of expertise was determined by (a) the length of time an employee had worked with a computer (computer expertise); (b) the number of programs s/he knew (program expertise); and (c) the daily time s/he spent working with the computer (daily work-time expertise). These different operationalizations of novices and experts led to different results. In contrast to widespread assumptions, experts did not make fewer errors than novices (except in knowledge errors). On the other hand, experts spent less time handling the errors than novices. A cluster analysis produced four groups in the workforce: occasional users, frequent users, beginners, and general users.”

Zapf, Dieter, Brodbeck, Felix C., Frese, Michael, Peters, Helmut and Prumper, Jochen (1992): Errors in Working in Office Computers: A First Validation of a Taxonomy for Observed Errors in a Field Setting. In International Journal of Human-Computer Interaction, 4 (4) pp. 311-339
“An action-oriented taxonomy of errors in human-computer interaction in the office differentiated four classes: functionality problems, usability problems, interaction problems, and inefficient behavior. Functionality problems were differentiated in how they affect the action process. Usability problems were differentiated according to levels of action regulation and steps in the action process. For example, conscious strategies were differentiated from automatic ones. To examine the taxonomy's construct validation, several hypotheses regarding error-handling time, need for external support, complexity at work, and novices versus experts were tested in a field study of 198 clerical workers at 11 German companies and 7 small firms. A total of 1,749 errors were observed within a 2-hour period, 1,306 were rated concordantly by two re-raters. As expected, errors resulting from conscious regulation and functionality problems needed more error-handling time than errors resulting from more automatic actions. There were more thought and memory errors at workplaces with high complexity. The most external support was needed for knowledge errors. Novices committed more knowledge errors and experts more habit errors. Practical implications are discussed both for software development and training.”

Prumper, Jochen, Frese, Michael, Zapf, Dieter and Brodbeck, Felix C. (1991): Errors in Computerized Office Work: Differences Between Novice and Expert Users. In ACM SIGCHI Bulletin, 23 (2) pp. 63-66
“This paper deals with errors by novices and experts when interacting with the computer in normal office work. Three criteria are discussed to determine the level of expertise: a) total length of time that the user has worked computers, b) number of programs known, and c) length of daily work-time with the computer. In contrast to widespread assumptions, experts did not make less errors than novices (except knowledge errors). On the other hand, experts spent less time handling the errors than novices. A cluster analysis produced groups of Occasional-, Frequent-, Beginning- and General Users in the work force.”

Frese, Michael, Brodbeck, Felix C., Zapf, Dieter and Prumper, Jochen (1990): The Effects of Task Structure and Social Support on Users' Errors and Error Handling. In: Diaper, Dan, Gilmore, David J., Cockton, Gilbert and Shackel, Brian (eds.) INTERACT 90 - 3rd IFIP International Conference on Human-Computer Interaction August 27-31, 1990, Cambridge, UK. pp. 35-41.
“The relationship of four organizational variables-job complexity, job discretion, social climate, and the organization of the computer advisory service-with number and type of errors and use of support facilities was studied in a field observational study. 198 subjects from 12 different public and private companies in the southern part of the Federal Republic of Germany (secretaries, typists, specialists, low level managers) were observed for 2 hours while they used computers during their work. They also filled out a questionnaire (N=232). There were a number of small but significant and practically important relationships, e.g. errors pertaining to conscious strategies happened more often in more complex jobs. Perceived support by supervisors and co-workers was related to whether these people were asked in case of an error. Decentralized advisory services were preferred and used more often by users than centralized services.”

Frese, Michael, Albrecht, Karen, Altmann, Alexandra, Lang, Jutta, Papstein, Patricia Von, Peyerl, Reinhard, Prumper, Jochen, Schulte-Gocking, Heike, Wankmuller, Isabell and Wendel, Rigas (1988): The Effects of an Active Development of the Mental Model in the Training Process: Experimental Results in a Word Processing System. In Behaviour and Information Technology, 7 (3) pp. 295-304
“Three different training programmes for a word processing system were experimentally compared: (1) a sequential programme, which taught low-level skills and which did not help the user actively to develop a mental model, (2) a hierarchical programme, which provided an explicit and integrated conceptual model of the system to the user and (3) a programme in which the users were asked to develop hypotheses on the functioning of the software and in which they were encouraged to use an active and exploratory approach. From an action theory point of view it was hypothesized that the third group would be superior to the first group. In an experimental study with two training sessions each of two hours and a two-hour testing session (n=15), this was shown to be the case for several performance criteria (error time, transfer and experimenter rating). Additionally, an interindividual difference variable to measure the individual learning style was used, giving results that could be interpreted in a similar way to the experimental results.”
