Why Do We Leave Original Copies in Photocopy Machines….Post-completion Errors in Problem Solving

Abstract (Via Simon Y. W. Li, Ann Blandford, Paul Cairns & Richard M. Young)

A post-completion error is a specific form of omission error occurring after some task goal has been accomplished – for example, forgetting to collect your original after photocopying. Using a novel experimental paradigm, this study demonstrates the cognitive robustness of postcompletion error: that it occurs not only in routine procedural tasks but also in problem-solving situations. The effect of a simple static visual cue to mitigate the error was also assessed by testing two different interfaces through which users engaged in problem-solving. The findings suggest that even a simple static cue can reduce the error rate, though not eliminate it.
