RESUMEN

Error-related negativity (ERN) has been used to investigate neural mechanisms underlying error processing and conflict monitoring. Recent evidence highlights that affective and motivational states modulate the ERN and that aversiveness of errors plays a vital role in error monitoring. Therefore, our primary objective was to systematically evaluate and describe the influence of affect state-related manipulations on the ERN. A total of 51 publications identified from PsyInfo, PubMed, and PsyArticles databases were included following the Prisma procedures for systematic reviews. Papers were analyzed using sample attributes, psychological paradigms, and states manipulations. The present study shows that the ERN component has recurrently appeared to be sensitive to manipulations of affective states in the reviewed literature. However, conclusive findings concerning the affect state-dependent properties of the ERN remain elusive. Results are discussed considering heterogeneity in paradigms, variables, and the state-trait interactions. Furthermore, recommendations for future high-quality studies are provided along with the necessity of upcoming high-power replication attempts and more studies with positive affect manipulations.

RESUMEN

Error monitoring allows for the efficient performance of goal-directed behaviors and successful learning. Furthermore, error monitoring as a metacognitive ability may play a crucial role for neuropsychological interventions, such as rehabilitation. In the past decades, research has suggested two electrophysiological markers for error monitoring: the error-related negativity (ERN) and the error positivity (Pe), thought to reflect, respectively, error detection and error awareness. Studies on several neurological diseases have investigated the alteration of the ERN and the Pe, but these findings have not been summarized. Accordingly, a systematic review was conducted to understand what neurological conditions present alterations of error monitoring event-related potentials and their relation with clinical measures. Overall, ERN tended to be reduced in most neurological conditions while results related to Pe integrity are less clear. ERN and Pe were found to be associated with several measures of clinical severity. Additionally, we explored the contribution of different brain structures to neural networks underlying error monitoring, further elaborating on the domain-specificity of error processing and clinical implications of findings. In conclusion, electrophysiological signatures of error monitoring could be reliable measures of neurological dysfunction and a robust tool in neuropsychological rehabilitation.

RESUMEN

Objective To compare performance of children with attention deficit hyperactivity disorders-combined (ADHD-C) type with control children in multi-source interference task (MSIT) evaluated by means of error related negativity (ERN). Method We studied 12 children with ADHD-C type with a median age of 7 years, control children were age- and gender-matched. Children performed MSIT and simultaneous recording of ERN. Results We found no differences in MSIT parameters among groups. We found no differences in ERN variables between groups. We found a significant association of ERN amplitude with MSIT in children with ADHD-C type. Some correlation went in positive direction (frequency of hits and MSIT amplitude), and others in negative direction (frequency of errors and RT in MSIT). Conclusion Children with ADHD-C type exhibited a significant association between ERN amplitude with MSIT. These results underline participation of a cingulo-fronto-parietal network and could help in the comprehension of pathophysiological mechanisms of ADHD. .


Objetivo Comparar el rendimiento de un grupo de niños con trastorno por déficit de atención-hiperactividad de tipo combinado (TDAH-C), con niños controles, en la tarea de interferencia multi-fuente (TIMF), evaluado por la negatividad relacionada al error (NRE). Método Estudiamos 12 niños con TDAH-C con una mediana de 7 años, los controles estuvieron pareados por edad y género. Los niños realizaron la TIMF con registros simultáneos de NRE. Resultados No encontramos diferencias en los parámetros de la TIMF entre grupos. No encontramos diferencias en las variables de la NRE entre grupos. Encontramos asociaciones significativas entre la amplitud de la NRE en niños con TDAH-C. Una correlación fue en dirección positiva: (frecuencia de aciertos y amplitud de TIMF), y otras fueron en dirección negativa (frecuencia de errores y el tiempo de respuesta en la TIMF). Conclusión Los niños con TDAH-C presentan una asociación significativa entre la amplitud de la NRE con la TIMF. Los resultados sugieren la participación de la red cíngulo-fronto-parietal y pueden ayudar en la comprensión de los mecanismos fisiopatológicos del TDAH-C. .

RESUMEN

Investigaciones con Potenciales Relacionados a Eventos han demostrado la existencia de un componente llamado Negatividad Relacionada a Retroalimentación de Error, el cual ha sido referido como una deflexión negativa que distingue entre ganancias y pérdidas, en tanto resultados esperados y no esperados respectivamente. Así, mientras algunos estudios han operacionalizado la idea de resultado esperado como la probabilidad de ganar vs. Perder, otros lo han hecho como la magnitud esperada de las recompensas. Hasta ahora existe poca investigación tendiente a observar cómo estas interpretaciones alternativas de "resultado esperado", o su interacción en términos de un modelo de "valor esperado" que las integre, afectan la Negatividad Relacionada a Retroalimentación de Error. El presente trabajo contextualiza el estudio de los mecanismos cerebrales asociados a la toma de decisiones, situando los estudios de Negatividad Relacionada a Retroalimentación de Error en su contexto teórico, revisa las dos tendencias de estudio desarrolladas hasta la fecha y explora posibilidades de ampliación del estudio de este componente en el contexto del naciente campo transdisciplinario de la neuroeconomía.


Studies using Event-Related Potentials have shown the existence of a component called Feedback Error-Related Negativity (fERN). This component has been characterized as a negative deflection which responds differentially to profits and losses in terms of expected and unexpected outcomes. Thus, while some studies have defined the idea of "expected outcome" as the probability to win vs. to lose, others have defined it as the expected size of rewards. How these alternative interpretations of "expected outcome" affect the fERN's research, and the effects of their interaction under a specific model of "expected value" has not been properly assessed. This work contextualizes the general study of neural mechanisms involved in decisionmaking processes, putting the fERN studies in context; besides, it reviews the two main approaches to its research; and finally, it explores the possibilities to further expand the fERN studies, in the context of the transdisciplinary rising field of neuroeconomics.
