    Losing a point in tennis could result from poor shot selection or faulty stroke execution. To explore how the brain responds to these different types of errors, we examined feedback-locked EEG activity while participants completed a modified version of a standard three-armed bandit probabilistic reward task. Our task framed unrewarded outcomes as the result of either errors of selection or errors of execution. We examined whether amplitude of a medial frontal negativity (the feedback-related negativity [FRN]) was sensitive to the different forms of error attribution. Consistent with previous reports, selection errors elicited a large FRN relative to rewards, and amplitude of this signal correlated with behavioral adjustment after these errors. A different pattern was observed in response to execution errors. These outcomes produced a larger FRN, a frontocentral attenuation in activity preceding this component, and a subsequent enhanced error positivity in parietal sites. Notably, the only correlations with behavioral adjustment were with the early frontocentral attenuation and amplitude of the parietal signal; FRN differences between execution errors and rewarded trials did not correlate with subsequent changes in behavior. Our findings highlight distinct neural correlates of selection and execution error processing, providing insight into how the brain responds to the different classes of error that determine future action.

    OBJECTIVE: First branchial cleft anomalies are rare congenital head and neck lesions. Literature pertaining to classification, work up and surgical treatment of these lesions is limited and, in some instances, contradictory. The goal of this work is to provide refinement of the classification system of these lesions and to provide guidance for clinicians to aid in the comprehensive management of children with first branchial cleft anomalies.

    MATERIALS AND METHODS: Delphi method survey of expert opinion under the direction of the International Pediatric Otolaryngology Group (IPOG) was conducted to generate recommendations for the definition and management of first branchial cleft anomalies. The recommendations are the result of expert consensus and critical review of the literature.

    RESULTS: Consensus recommendations include evaluation and diagnostic considerations for children with first branchial cleft anomalies as well as recommendations for surgical management. The current Work classification system was reviewed, and modifications were made to it to provide a more cogent categorization of these lesions.

    CONCLUSION: The mission of the International Pediatric Otolaryngology Group (IPOG) is to develop expertise-based recommendations based on review of the literature for the management of pediatric otolaryngologic disorders. These consensus recommendations are aimed at improving care of children presenting with first branchial cleft anomalies. Here we present a revised classification system based on parotid gland involvement, with a focus on avoiding stratification based on germ layer, in addition to guidelines for management.
