Decision processes in human performance monitoring.

ABSTRACT: The ability to detect and compensate for errors is crucial in producing effective, goal-directed behavior. Human error processing is reflected in two event-related brain potential components, the error-related negativity (Ne/ERN) and error positivity (Pe), but the functional significance of both components remains unclear. Our approach was to consider error detection as a decision process involving an evaluation of available evidence that an error has occurred against an internal criterion. This framework distinguishes two fundamental stages of error detection--accumulating evidence (input), and reaching a decision (output)--that should be differentially affected by changes in internal criterion. Predictions from this model were tested in a brightness discrimination task that required human participants to signal their errors, with incentives varied to encourage participants to adopt a high or low criterion for signaling their errors. Whereas the Ne/ERN was unaffected by this manipulation, the Pe varied consistently with criterion: A higher criterion was associated with larger Pe amplitude for signaled errors, suggesting that the Pe reflects the strength of accumulated evidence. Across participants, Pe amplitude was predictive of changes in behavioral criterion as estimated through signal detection theory analysis. Within participants, Pe amplitude could be estimated robustly with multivariate machine learning techniques and used to predict error signaling behavior both at the level of error signaling frequencies and at the level of individual signaling responses. These results suggest that the Pe, rather than the Ne/ERN, is closely related to error detection, and specifically reflects the accumulated evidence that an error has been committed.

Project description:ContextResidents are expected to ask for help when feeling insufficiently confident or competent to act in patients' best interests. While previous studies focused on the perspective of supervisor-resident relationships in residents' help-seeking decisions, attention for how the workplace environment and, more specifically, other health care team members influence these decisions is limited. Using a sociocultural lens, this study aimed to explore how residents' decision-making processes to seek help are shaped by their workplace environment.MethodsThrough a constructivist grounded theory methodology, we purposively and theoretically sampled 18 residents: 9 juniors (postgraduate year 1/2) and 9 seniors (postgraduate year 5/6) at Amsterdam University Medical Centers. Using semi-structured interviews, participating residents' decision-making processes to seek help during patient care delivery were explored. Data collection and analysis were iterative; themes were identified using constant comparative analysis.ResultsResidents described their help-seeking decision-making processes as an 'act of performance': they considered how asking for help could potentially impact their assessments. They described this act of performance as the product of an internal 'balancing act' with at its core the non-negotiable priority for providing safe and high-quality patient care. With this in mind, residents weighed up demonstrating the ability to work independently, maintaining credibility and becoming an accepted member of the health care team when deciding to seek help. This 'balancing act' was influenced by sociocultural characteristics of the learning environment, residents' relationships with supervisors and the perceived approachability of other health care team members.ConclusionsThis study suggests that sociocultural forces influence residents to experience help-seeking as an act of performance. Especially, a safe learning environment resulting from constructive relationships with supervisors and the approachability of other health care team members lowered the barriers to seek help. Supervisors could address these barriers by having regular conversations with residents about when to seek help.
