Pourquoi votre cerveau est mauvais pour prédire le bonheur | David Zald | TEDxNashville Salon

Cette intervention TEDxNashville Salon de David Zald, neuroscientifique, explore pourquoi nous anticipons mal ce qui nous rendra heureux. Il évoque la disparition progressive du plaisir, la sous-estimation des expériences qui demandent un effort et la difficulté parfois plus grande de se lancer que de pratiquer l'activité elle-même. Le discours aborde aussi les neurosciences du flow, cet état d'absorption totale où l'inquiétude et la conscience de soi s'effacent. Selon l'orateur, un engagement porteur de sens peut apporter un bonheur plus durable que le plaisir ou la réussite seuls.

• Pourquoi le plaisir s'estompe et pourquoi le bonheur est difficile à prévoir
• Pourquoi les activités exigeant un effort sont sous-estimées
• Les neurosciences du flow

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. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
