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 Palsy08:26

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 Neuroscience08:33

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...

科学分野:

  • 認知心理学;神経科学;人間工学

背景:

  • 熟練度とはタスクのスキルレベルですが、パフォーマンス基準が満たされた場合でも注意資源の需要は変化する可能性があります。;既存の方法では、認知的負荷に関連する熟練度の微妙な変化を完全に捉えられない場合があります。

研究 の 目的:

  • タスク非関連プローブ技術が注意資源を測定することによって熟練度の変化を評価できるかどうかを調査すること。;特定の基準を満たすために必要な認知的努力に反復タスクパフォーマンスがどのように影響するかを評価すること。

主な方法:

  • 参加者は4週間、毎週シミュレーター運転タスクを実行し、操舵制御基準を満たしました。;タスク遂行中に聴覚誘発電位（AEP）を測定するためにタスク非関連聴覚プローブが使用されました。;注意資源配分を推定するために事象関連電位（ERP）が分析されました。

主要な成果:

  • 聴覚誘発電位（AEP）のP2成分の振幅は4週間で増加しました。;この増加は、操舵制御基準を維持するために必要な注意資源の減少を示しています。;熟練度が向上し、タスクの認知的負荷が減少しました。

結論:

  • タスク非関連プローブ技術は、熟練度の変化を評価するための実行可能な方法です。;この技術は、スキル開発に伴う注意資源需要の変化を定量化します。;練習によって習熟度が高まるにつれて、認知的努力は減少します。
