なぜ脳は幸福を予測するのが苦手なのか | デイビッド・ザルド | TEDxNashville Salon

神経科学者デイビッド・ザルドによるこのTEDxNashville Salonでの講演は、人がなぜ何で幸せになれるかを誤って予想しがちなのかを取り上げています。快楽がなぜ時間とともに薄れるのか、努力を伴う経験がなぜ過小評価されるのか、そして活動そのものより取りかかることのほうが難しい場合がある理由を説明しています。また、不安や自己意識が薄れる完全な没入状態であるフロー（flow）の神経科学にも触れています。ザルドは、意味のある関わりが、快楽や達成だけよりも持続的な幸福をもたらす可能性があると示唆しています。

• 快楽が薄れる理由と幸福の予測が難しい理由
• 努力を伴う活動が過小評価される理由
• フローの神経科学

Why are we so bad at predicting what will make us happy? In this TEDxNashville talk, Zald explores why pleasure fades, why we underestimate experiences that require effort, and why getting started can be harder than the activity itself. He also examines the neuroscience of **flow**—the state of complete absorption in which worry and self-consciousness fade—and why meaningful engagement may bring more lasting happiness than pleasure or achievement. What if our brains weren't designed to keep us happy, but to keep us learning, exploring, and growing? Perhaps happiness isn't the destination. Perhaps it's what happens when we stop chasing it and become fully engaged in living. David Zald uses functional neuroimaging and neuropsychological techniques to examine and map the cognitive, affective and sensory functions of the orbitofrontal cortex, amygdala and the mesolimbic dopamine system. This work particularly focuses on understanding the manner in which individual differences in the functioning of these systems contributes to personality and risk for psychopathology. In recent years this work has examined the interaction of emotion and attention, and the substrates of economic decision making, particularly as it relates to motivation, the willingness to expend effort and reward processing, both in healthy individuals and people with certain forms of psychopathology. A final area of focus is the examination of the neural substrates of dimensions of psychopathology, specifically factors of psychopathology that cross the boundaries of different psychiatric disorders.
