まとめ
スマートフォンの問題的な使用は 報酬処理中の脳の反応の変化と関連しています 機能不全の報酬フィードバックは ストレス関連のPSUを増幅し デジタル依存症の介入の潜在的マーカーとして ERPを示唆します
科学分野:
- 神経科学
- 心理学
- デジタル・ヘルス
背景:
- スマートフォンの問題的な使用 (PSU) は,しばしばストレスと機能不全の報酬処理に関連して,公衆衛生上の懸念が高まっています.
- この機能障害は 報酬の予期期期間に神経の活動が増加し 報酬の受給期間に神経の活動が低下し 感情の調節に影響します
研究 の 目的:
- 報酬予想とフィードバックにおけるPSUとイベント関連ポテンシャル (ERP) の関連性を調査する.
- エコロジカル・モメンタリー・アセスメントを使用して,報酬処理機能障害が日常のストレスとPSUエスカレーションの関係をどのように媒介するのかを探る.
主な方法:
- 44人のPSU参加者と50人の健康な対照者 (HC) の間に記録されたERPは,金銭的インセンティブの遅延作業です.
- エコロジカル・モメンタリー・アセスメントで14日間,一時的なストレス,PSUレベル,スクリーン時間のデータを収集した.
主要な成果:
- PSUの参加者は,HCと比較して,報酬の予期中により大きなP3振幅を示し,フィードバック中にRewPとfb-P3振幅を減少させた.
- 一時的なストレスは PSUとスクリーン時間の増加と正に相関しています
- 鈍化したRewP反応は,ストレスによって引き起こされたPSUとスクリーン時間の増加を増幅し,緩和的な役割を果たしました.
結論:
- 報酬に関連するERP,特にRewPは,PSUを特定するための神経マーカーとして機能します.
- 機能不全の報酬処理は ストレス関連のPSUを悪化させ デジタル依存症の予防と介入戦略に 洞察を与えてくれます

Psychological Responses to Stress
98
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...

Introduction to Stress and Lifestyle
177
Stress is a multifaceted response to events perceived as challenging or threatening, highlighting physical, emotional, cognitive, and behavioral reactions. Physically, stress can lead to fatigue, sleep disruptions, and various health issues such as frequent colds, chest pains, and nausea. Emotionally, it can manifest as anxiety, depression, irritability, and anger triggered by both minor and major life events. Cognitively, it may result in difficulty in concentration, memory, and...

Lazarus's Cognitive Appraisal Theory
506
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.

Types of Stressors
296
A stressor is any event, condition, or stimulus that triggers stress and causes a physical or psychological response in the body. Stressors can be categorized into three main types: catastrophes; significant life changes; and daily hassles, including social stress. Each can be detrimental to physical and mental well-being.
Catastrophes
Catastrophes refer to large-scale, unpredictable events that create overwhelming stress and a sense of threat. Examples include natural disasters like...

Schemas
12.0K
A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.
