Today's society is pleasure seeking. We expect to obtain pleasurable experiences fast and easily. We are used to hyper-palatable foods and drinks, and we can get pornography, games and gadgets whenever we want them.
with this type of pleasure-maximizing choice behaviour we may be turning ourselves into mindless pleasure junkies, handing over our free will for the next dopamine shoot. Pleasure-only activities are fun. In excess, however, such activities might have negative effects on our biopsychological health: they provoke a change in the neural mechanisms underlying choice behaviour. Choice behaviour becomes biased towards short-term pleasure-maximizing goals, just as in the addicted brain (modulated by the amygdala, posterior ventromedial prefrontal cortex' (VMPFC), striatum, nucleus accumbens; 'A-system') and away from long-term prosperity and general well-being maximizing objectives (normally ensured by the insula, anterior VMPFC, hippocampus, dorsolateral prefrontal cortex (DLPFC), anterior cingulate cortex (ACC); 'I-system'). This paper outlines, first, what 'pleasure' is and what 'pleasure-only' activities are (e.g. social media engagement, hyper-palatable eating). Second, an account is given of the type of action that might aid to maintain the neural systems underlying choice behaviour balanced. Finally, it is proposed that engagement with the arts might be an activity with the potential to foster healthy choice behaviour-and not be just for pleasure. The evidence in this rather new field of research is still piecemeal and inconclusive. This review aims to motivate targeted research in this domain.
当今社会追求享乐。我们期望快速且轻松地获得愉悦体验。我们习惯了极易入口的食物和饮品,并且随时随地都能获取色情内容、游戏和小玩意儿。
通过这种追求最大愉悦感的选择行为,我们可能正把自己变成毫无思考能力的愉悦成瘾者,为了下一次多巴胺释放而交出我们的自由意志。仅为获取愉悦的活动很有趣。然而,过度进行此类活动可能会对我们的生物心理健康产生负面影响:它们会引发选择行为背后神经机制的变化。选择行为会偏向于追求短期愉悦最大化的目标,就如同成瘾大脑(由杏仁核、腹内侧前额叶皮质后部(VMPFC)、纹状体、伏隔核调节;“A系统”)那样,而远离追求长期繁荣和总体幸福感最大化的目标(通常由脑岛、腹内侧前额叶皮质前部、海马体、背外侧前额叶皮质(DLPFC)、前扣带回皮质(ACC)确保;“I系统”)。本文首先概述了“愉悦”是什么以及“仅为获取愉悦”的活动有哪些(例如参与社交媒体、食用极易入口的食物)。其次,阐述了可能有助于维持选择行为背后神经系统平衡的行动类型。最后,提出参与艺术活动可能是一种有潜力促进健康选择行为的活动——而不只是为了获得愉悦。在这个相当新的研究领域,证据仍然零散且尚无定论。本综述旨在推动该领域的针对性研究。
