We explored children's and adults' ability to disengage from current physiological states when forecasting future desires. In Study 1, 8- to 13-year-olds and adults (N = 104) ate pretzels (to induce thirst) and then predicted and explained what they would want tomorrow, pretzels or water. Demonstrating life-span continuity, approximately 70% of participants, regardless of age, chose water and referenced current thirst as their rationale. Individual differences in working memory and undergraduate grade point average were positively related to performance on the pretzel task. In Study 2, we obtained baseline preferences from adults (N = 35) and confirmed that, prior to consuming pretzels, people do not anticipate wanting water more than pretzels the next day. Together, these findings indicate that both children and adults are tethered to the present when forecasting their future desires.
我们探讨了儿童和成人在预测未来欲望时,从当前生理状态中解脱出来的能力。在研究 1 中,8 至 13 岁的儿童和成人(N=104)吃椒盐卷饼(引起口渴),然后预测并解释他们明天想要什么,椒盐卷饼还是水。研究表明,无论年龄大小,大约 70%的参与者选择了水,并将当前的口渴作为他们的理由。工作记忆和本科平均绩点的个体差异与椒盐卷饼任务的表现呈正相关。在研究 2 中,我们从成年人(N=35)那里获得了基线偏好,并确认在食用椒盐卷饼之前,人们并不期望第二天比椒盐卷饼更想要水。总的来说,这些发现表明,儿童和成人在预测未来欲望时都受到当前的束缚。
