Event-related Potentials and the Oddball Task14:33

Event-related Potentials and the Oddball Task

29.2K
Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California
Given the overwhelming amount of information captured by the sensory organs, it is crucial that the brain is able to prioritize the processing of certain stimuli, to spend less effort on what might not be currently important and to attend to what is. One heuristic the brain uses is to ignore stimuli that are frequent or constant in favor of stimuli that are unexpected or unique. Therefore, rare...

Event-related Potentials During Target-response Tasks to Study Cognitive Processes of Upper Limb Use in Children with Unilateral Cerebral Palsy

12.6K
Several children with unilateral Cerebral Palsy seem to disregard the preserved capacity of their affected upper limb. This Developmental Disregard is extensively described in the literature but the involved cognitive processes have not been studied. To study underlying cognitive factors of upper limb control, an event-related potential protocol was developed.

Event Related Potentials (ERPs) and other EEG Based Methods for Extracting Biomarkers of Brain Dysfunction: Examples from Pediatric Attention Deficit/Hyperactivity Disorder (ADHD)

16.6K
EEG-methods are applied for extracting biomarkers of brain dysfunctions. The focus is on multi-channel event-related potentials (ERPs) recorded in a cued GO/NOGO task. Non-brain artifacts are corrected and ERPs are compared with the normative data. Examples relate to biomarkers for ADHD diagnosis and prediction of medication...

High Density Event-related Potential Data Acquisition in Cognitive Neuroscience

13.0K
Event-related potential (ERP) recording is under utilized in Cognitive Neuroscience because data acquisition techniques are not readily available and this method often has poor spatial resolution. To foster the increased use of ERPs in Cognitive Neuroscience, the present article details key techniques involved in high density ERP data...

Área de la Ciencia:

  • Psicología Cognitiva; Neurociencia; Ingeniería de Factores Humanos

Sus antecedentes:

  • La competencia es el nivel de habilidad para las tareas, pero las demandas de recursos atencionales pueden variar incluso cuando se cumplen los criterios de rendimiento.; Los métodos existentes pueden no capturar completamente los cambios sutiles en la competencia relacionados con la carga cognitiva.

Objetivo del estudio:

  • Investigar si la técnica de sonda irrelevante para la tarea puede evaluar los cambios en la competencia midiendo los recursos atencionales.; Evaluar cómo el rendimiento repetido de la tarea afecta el esfuerzo cognitivo requerido para cumplir un criterio específico.

Principales métodos:

  • Los participantes realizaron una tarea de conducción en simulador semanalmente durante cuatro semanas, cumpliendo un criterio de control de la dirección.; Se utilizaron sondas auditivas irrelevantes para la tarea para medir los potenciales evocados auditivos (PEA) durante el rendimiento de la tarea.; Se analizaron los potenciales cerebrales relacionados con eventos (ERPs) para estimar la asignación de recursos atencionales.

Principales resultados:

  • La amplitud del componente P2 de los potenciales evocados auditivos (PEA) aumentó durante las cuatro semanas.; Este aumento indica una reducción en los recursos atencionales necesarios para mantener el criterio de control de la dirección.; La competencia mejoró, lo que llevó a una disminución de la carga cognitiva para la tarea.

Conclusiones:

  • La técnica de sonda irrelevante para la tarea es un método viable para evaluar los cambios en la competencia.; Esta técnica cuantifica los cambios en las demandas de recursos atencionales a medida que se desarrolla la habilidad.; El esfuerzo cognitivo disminuye a medida que los individuos se vuelven más competentes a través de la práctica.
