まとめ
努力の知覚 (PE) は,精神運動能力を維持するための認知的需要とともに増加します. しかし,固定型PEの高い認知需要はパフォーマンスを低下させ,PEがタスクの強度を監視できることを示唆しています.
科学分野:
- 認知心理学とは,認知心理学である.
- 神経科学は神経科学である.
- エンジンの制御装置
背景:
- モチベーション強度理論は,努力の知覚 (PE) を,目標指向の行動を自己調節するためのリソースモニタリングメカニズムとして置く.
- 資源モニタリングと自己調節は,通常,認知または運動領域内で孤立して研究されます.
- 精神運動のタスクにおける認知需要とPEの相互作用を調査することは,労力の調節を理解するために重要である.
研究 の 目的:
- 心理運動のタスクにおける認知需要が PE にどのように影響するかを調べる.
- 目標PEの強度を規定することで,作業のパフォーマンスに与える影響を評価する.
- 心理運動タスクの強度をモニタリングし,処方するためのメトリックとしてPEの潜在能力を探求する.
主な方法:
- 参加者内の2つの実験は,それぞれ20人の参加者を対象に実施されました.
- 実験1:上肢の精神運動の課題 (BoxとBlock,指す) で,異なる認知的要求 (Stroopタスク) の下でPEを評価した.
- 実験2: 操作された認知の需要の下で固定PEで自己ペースの指すタスクで評価されたパフォーマンス. 生理学的測定値 (心拍数,呼吸率,EMG) をモニタリングした.
主要な成果:
- 実験1では,認知的需要の増加に伴いPEが増加し,精神運動のタスクにおけるパフォーマンスの維持を助けました.
- 実験2では,固定型PE下での高度の認知需要により,自己ペースで指すタスクのパフォーマンスが低下しました.
- 心拍数は認知的需要に敏感でしたが,実験1の低~中程度の増加を完全に捉えることができませんでした.
結論:
- 努力の知覚は,精神運動のタスクの強さを処方し,モニターするために効果的に使用することができます.
- 発見は,努力に基づく意思決定と認知および運動領域の自己規制におけるPEの役割を支持しています.
- この研究は,PEの神経生理学と認知と運動の努力の間の関係を調査するための道を開きます.

01:38Cognitive Dissonance
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
01:04Social Facilitation
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.
01:20Motor Unit Stimulation
When the neuron of a motor unit fires an action potential, it triggers a series of events, leading to a twitch contraction in the muscle fibers. The process of excitation-contraction coupling is crucial in relaying the action potential to the muscle fibers.
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...

01:27Exercise and Muscle Performance
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

01:24Muscle Coordination and Action
Muscle coordination is a complex and finely tuned process essential for smooth and purposeful movements like flexion, extension, adduction, abduction, and rotation. The human body orchestrates the actions of various muscles working in concert, each with a specific role. Four functional types describe how muscles work together: agonist, antagonist, synergist, and fixator.
Agonists
Agonist muscles, often called prime movers, are the primary muscles responsible for producing a specific movement.

01:29Self-Efficacy
Self-efficacy is the belief in one's capacity to organize and execute actions necessary to manage prospective situations. This belief significantly influences how individuals approach goals, tasks, and challenges across different domains of life.Psychological and Educational ImpactsIndividuals with strong self-efficacy are more resilient in the face of difficulties. They are more likely to adopt effective problem-solving strategies, persist through obstacles, and regulate emotions such as...
