まとめ

高度のテスト不安 (HTA) は,特にストレス下では,作業記憶 (WM) と注意制御を損なう. HTAの個人は,低テスト不安 (LTA) の個人に比べて異なる脳活動パターンを示し,認知機能が損なわれていることを示しました.

科学分野:

認知神経科学とは
心理学心理学とは

背景:

テスト不安は,作業記憶 (WM) や注意制御などの認知機能に悪影響を及ぼします.
アテンションコントロール理論 (ACT) は,高いテスト不安 (HTA) は,特に高い認知負荷と脅威条件下では,注意制御の障害につながると主張しています.

研究の目的:

高テスト不安 (HTA) と低テスト不安 (LTA) の個体間の感情的な作業記憶処理の違いを調査する.
HTAおよびLTAの個体における作業記憶のパフォーマンスと神経活動 (EEG) に関する認知負荷と脅威刺激の影響を調査する.

主な方法:

参加者は,テスト不安スケール (TAS) を使用してHTAまたはLTAとして分類されました.
Sternberg WMタスクは,EEGと併せて,さまざまな認知負荷 (高/低) と刺激タイプ (中立/脅威) の下で,エンコーディングとメンテナンスフェーズ中の脳活動を測定するために使用されました.

主要な成果:

高負荷のWMエンコーディング中に,HTA個人は中性刺激でテータパワーの増加を示したが,LTA個人は脅威刺激でテータパワーの増加を示した.
グループ間のメンテナンスフェーズでは,テータパワーの有意な差は見つかりませんでした.
LTA個体と比較して,メンテナンス段階でHTA個体においてアルファパワーの上昇が観察され,注意力資源の割り当てがより高いことが示唆されました.

結論:

HTAの個人は,神経活動パターンの変化によって証明される,作業記憶の欠陥を示します.
高度な認知負荷下での脅威刺激への反応として,テータ活性を調節する彼らの能力は損なわれています.
HTAの個人は,WMのメンテナンス中に無関係な情報を抑制するために,より多くの注意制御リソースを必要とします.

Working Memory

Working Memory

Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

The Influence of Cognition on Affect

The Influence of Cognition on Affect

Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

Psychological Responses to Stress

Psychological Responses to Stress

Psychological responses to stress encompass the various cognitive and emotional reactions individuals experience when faced with challenging or threatening situations, such as a job loss. Prolonged exposure to stressors can disturb emotional balance, increasing negative emotions (e.g., anxiety and sadness) and diminishing positive emotions (e.g., joy and satisfaction). These persistent emotional shifts are associated with an increased risk of both physical illness and mental health issues, such...

Lazarus's Cognitive Appraisal Theory

Lazarus's Cognitive Appraisal Theory

Cognitive psychologist Richard Lazarus proposed the cognitive-mediational theory of emotions, which emphasizes how individuals' assessments of stressors significantly affect their experience of stress. According to Lazarus, the stress response is determined by a two-step appraisal process: primary appraisal and secondary appraisal. These cognitive appraisals help individuals evaluate the potential impact of a stressor and determine the adequacy of their coping resources.
Primary Appraisal:...

Cognitive Theories: Schachter-Singer Theory of Emotion

Stanley Schachter and Jerome Singer proposed the two-factor theory of emotion, which emphasizes the interplay between physiological arousal and cognitive labeling in forming emotional experiences. This theory suggests that emotions are not simply a result of physiological responses but rather a combination of these responses and the individual's cognitive interpretation of them.
Physiological Arousal and Cognitive Labeling
According to this theory, when an individual experiences...
