Motivational Bias01:25

Motivational Bias

296
Cognitive bias results from limitations in thinking and information processing, leading to systematic errors in judgment. Conversely, motivational bias stems from personal desires or emotions, causing distortions in perception to align with self-interest. Motivational bias influences how individuals perceive and attribute causes to events, often shaped by personal needs, goals, and self-esteem preservation. This bias can distort judgment, leading to inaccurate assessments of success, failure,...

The Placebo Effect01:54

The Placebo Effect

6.8K
The placebo effect occurs when people's expectations or beliefs influence or determine their experience in a given situation. In other words, simply expecting something to happen can actually make it happen.

Blinding01:11

Blinding

3.8K
Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.

Blind Procedures02:07

Blind Procedures

12.8K
Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

Nociception01:44

Nociception

33.0K
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

Halo Effect01:27

Halo Effect

365
The halo effect is a cognitive bias in which an individual's overall impression influences judgments about their specific traits. This psychological phenomenon leads people to associate positive characteristics with those they perceive as generally good and negative characteristics with those they view as bad. This effect is particularly influential in social perception, professional evaluations, and decision-making processes.The Psychological Basis of the Halo EffectThe halo effect is rooted...

まとめ

痛みに向けた解釈バイアスの修正は、痛みの期待によって媒介されるノセボ過剰痛を増加させました。痛みの解釈の低減は、臨床設定におけるノセボ痛の低減を標的とする可能性があります。

科学分野:

  • 心理学
  • 疼痛科学
  • 認知神経科学

背景:

  • 解釈バイアス、すなわち曖昧な刺激を痛みに関連するものとして解釈する傾向は、痛みの重症度と相関します。
  • ノセボ過剰痛のメカニズムを理解することは、効果的な疼痛管理戦略を開発するために不可欠です。

研究 の 目的:

  • 解釈のための認知的バイアス修正（CBM-I）がノセボ過剰痛に影響を与えるかどうかを調査すること。
  • 解釈バイアスとノセボ過剰痛の関係における痛みの期待の媒介的役割を決定すること。

主な方法:

  • 参加者は、痛み関連解釈または良性解釈を標的とするCBM-Iにランダムに割り当てられました。
  • ノセボ誘発手順には、偽の経皮的電気神経刺激（TENS）と熱痛のペアリングが含まれていました。
  • ノセボ過剰痛は、同一の熱刺激下でのTENSおよび非TENSトライアル中の痛みの評価を比較することによって評価されました。

主要な成果:

  • ノセボ過剰痛は確実に観察され、痛みの期待によって媒介されました。
  • CBM-Iは解釈バイアスを首尾よく操作し、痛みバイアス群はより強いバイアスを示しました。
  • 痛み中心のCBM-Iを受けた参加者は、良性中心の群と比較して有意に高いノセボ過剰痛を示しました。

結論:

  • 痛み関連解釈を標的とする認知的バイアス修正は、ノセボ過剰痛を増幅します。
  • 解釈バイアスは、痛みの期待の増加を通じてノセボ過剰痛に因果的な役割を果たします。
  • CBM-Iを介した痛み関連解釈バイアスの低減は、臨床的疼痛管理のための潜在的な心理的介入を表します。
