Social interactions are theorized to inform relation-inferred self-efficacy (RISE), which, in turn, may influence self-efficacy and behavior. This study investigated the effects of peer encouragement on RISE, task self-efficacy, and physical performance. Children (N = 84) were assigned to dyads and randomized to provide peer encouragement to one another or not (control group). Participants completed two endurance handgrip trials, separated by a cognitively demanding task intended to induce mental fatigue and increase the salience of the peer encouragement manipulation. Participants in the experimental group exchanged words of encouragement prior to the second endurance trial, whereas those in the control group did not. The peer encouragement group reported higher RISE and showed increased performance across trials compared with controls. Providing peer encouragement prior to a challenging physical task was associated with more positive RISE perceptions and improved physical performance.

社交互动被理论化为关系推断自我效能（RISE），这反过来又可能影响自我效能和行为。本研究调查了同伴鼓励对 RISE、任务自我效能感和身体表现的影响。儿童（N  = 84）被分配到二人一组，并随机分配是否互相提供同伴鼓励（对照组）。参与者完成了两项耐力握力试验，其间进行了一项认知要求较高的任务，旨在引起精神疲劳并增加同伴鼓励操作的显着性。实验组的参与者在第二次耐力试验之前交换了鼓励的话语，而对照组的参与者则没有。与对照组相比，同伴鼓励组报告了更高的 RISE，并且在整个试验中表现出更高的表现。在进行具有挑战性的体力任务之前提供同伴鼓励与更积极的 RISE 认知和改善的体能表现相关。
