Effect of pacing and working memory loads on error type patterns in a routine skill.
Event counting provides a laboratory paradigm for studying types and causes of error in routine activity. Experiment 1 demonstrated that as more time per event is allowed, counting errors typically are undercounts, then overcounts as the time per event is extended to approximately 3 s. Experiments 2 and 3 examined 2 possible causes of this phenomenon, forgetting and confusions due to overrehearsal of the next number to be used. These findings demonstrate that overcount errors during event counting are reduced by working memory loads, which may result from a lower ability to rehearse the current total. Implications for theoretical accounts of goal representation, control, and error monitoring are discussed.
