With rapid advancements in medicine, technology, and nutrition, the future holds the possibility of longer and healthier lives. Despite garnering attention from myriad disciplines, psychological perspectives on life extension are scarce. In three studies, we addressed this gap by exploring key mental characteristics and psychological variables associated with simulating an expanded life span and thus an extremely distant future self.
Three studies investigated the construal (i.e., valence, vividness, and visual perspective) of extremely distant future simulations and the extent to which participants felt connected to their future selves (i.e., self-continuity). Studies 1 and 2 investigated the characteristics of imagery associated with different ages ranging from near the current species maximum (e.g., 120, 150) to more highly hypothetical ages (e.g., 201, 501). Study 3 probed the mental construal of extreme aging among different populations (i.e., life-extension supporters, students, and Mechanical Turk workers). Studies also assessed participants' general feelings about the ethicality and likelihood of techniques that halt or reverse biological aging to help individuals live beyond the current life expectancy.
Participants in all studies reported being able to vividly imagine expanded aging scenarios (increased chronological, without biological, and aging), but these simulations were characterized by a decreased sense of connection to one's future self (i.e., self-continuity) compared to a control condition. Temporal distance did not, however, impact ratings of self-continuity when comparing experimental conditions (i.e., imagining one's self 120 vs 150 or 201 vs 501). Curiously, a sense of self-continuity (when simulating oneself well beyond the current life expectancy) remained intact for individuals who belonged to a community of life-extension supporters. The perceived likelihood and ethicality of extended life-span scenarios also varied significantly across different populations.
The current work is the first to quantify the disconnect between one's current and extremely distant (i.e., beyond the current life expectancy) future self. Given the behavioral implications of feeling disconnected from one's future self (e.g., failing to save for retirement or care for one's own physical health), these findings inform a critical barrier of extended life spans and provide insight into potential remedies (e.g., enhancing the perceived likelihood of living longer). Theoretical implications of hypotheticality and temporal distance, two key dimensions of Construal Level Theory, and their impact on the construal and self-continuity associated with future simulations are also discussed.
随着医学、技术和营养的迅速发展,未来人们有可能活得更长、更健康。尽管这一话题已引起众多学科的关注,但从心理学角度对延长寿命的探讨却很少。在三项研究中,我们通过探索与模拟延长寿命及由此产生的极其遥远的未来自我相关的关键心理特征和心理变量,填补了这一空白。
三项研究调查了对极其遥远的未来模拟的理解(即效价、生动性和视觉视角),以及参与者感觉与未来自我相连的程度(即自我连续性)。研究1和研究2调查了与不同年龄相关的意象特征,年龄范围从接近当前物种寿命上限(如120岁、150岁)到更具假设性的年龄(如201岁、501岁)。研究3探究了不同人群(即寿命延长支持者、学生和亚马逊土耳其机器人平台工作者)对极端衰老的心理理解。研究还评估了参与者对能够阻止或逆转生物衰老以帮助个体超越当前预期寿命的技术的道德性和可能性的总体看法。
所有研究中的参与者都报告称能够生动地想象延长衰老的情景(增加实际年龄,无生物衰老),但与对照条件相比,这些模拟的特点是与未来自我的联系感(即自我连续性)降低。然而,在比较实验条件时(即想象自己120岁与150岁或201岁与501岁),时间距离并未影响自我连续性的评分。奇怪的是,对于属于寿命延长支持者群体的个体,当模拟自己远超当前预期寿命时,自我连续性的感觉依然完好。不同人群对延长寿命情景的感知可能性和道德性也存在显著差异。
当前的研究首次量化了个体当前与极其遥远的(即超出当前预期寿命)未来自我之间的脱节。鉴于与未来自我脱节所带来的行为影响(如不为退休储蓄或不关心自身身体健康),这些发现揭示了延长寿命的一个关键障碍,并为潜在的补救措施(如提高对活得更长的感知可能性)提供了见解。还讨论了构念水平理论的两个关键维度——假设性和时间距离的理论意义,以及它们对与未来模拟相关的构念和自我连续性的影响。
