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 post-completion 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.
