A translational approach to investigating the effects of consequence‐based procedural fidelity errors postmastery

Procedural fidelity is the extent to which prescribed protocols are accurately and correctly implemented. Prior researchers found that consequence-based procedural fidelity errors can delay or impede learning, but not much is known about how they influence performance for tasks that have previously been mastered. The purpose of this study was to systematically replicate Falakfarsa et al. (2023) to further investigate how consequence-based errors affect performance postmastery. Twenty-four undergraduates mastered a computerized match-to-sample task under conditions of perfect fidelity (100%). Following mastery, consequence-based errors were introduced across varying levels of fidelity. For 13 participants, we observed decreased percentage of correct responses on the task in the presence of errors, with considerable intersubject variability. No effect of the independent variable was observed for 11 participants. The results suggest that error reinforcement was the more detrimental error type. We discuss the implications of the results and make several suggestions for future research.
