The Impact of Soft and Hard Tactile Experiences on Intertemporal Decision-Making—The Mediating Role of Uncertainty

本研究基于具身认知理论，探讨软硬触觉经验对跨期决策的影响，并通过不确定感这一中介变量解释其影响机制。研究1采用单因素两水平被试间设计(软球组、硬球组)，以114名成人为研究对象，被试被随机分配至不同的组别并充分按压小球后，通过滴定范式、定价范式测量个体的跨期决策行为；研究2以111名成人作为研究对象，以物体的软硬程度及作答环境中的座椅柔软度为自变量，不确定感为中介变量，并使用滴定范式测量跨期决策行为。研究1的结果显示，软硬触觉体验显著影响个体的跨期决策。研究2通过证明触觉体验影响个体不确定感进而影响决策行为，揭示了其背后的心理机制。This study, grounded in embodied cognition theory, examines the effects of soft and hard tactile experiences on intertemporal decision-making, focusing on the mediating role of uncertainty. Study 1 employed a single-factor, two-level between-subjects design with 114 adult participants, who were randomly assigned to either a soft ball group or a hard ball group. After engaging in tactile manipulation by pressing the balls, participants’ intertemporal decision-making was assessed using titration and valuation paradigms. Study 2 involved 111 participants, manipulating the softness and hardness of various objects and the cushioning of seating as independent variables while using uncertainty as a mediating variable. The titration paradigm was utilized to measure intertemporal decision-making behavior. Study 1 found that tactile sensations significantly influenced intertemporal decision-making. Study 2 revealed the underlying psychological mechanisms, demonstrating that these tactile experiences impacted decision-making processes by altering individuals’ perceptions of uncertainty.
