The Köhler effect is a social-psychological group motivation gain phenomenon that has been successfully adapted to video-based exercise games (exergames) using human partners. This research then shifted to using software-generated partners (SGPs), providing greater flexibility and adaptability to manipulate the game environment to be most motivating for the user. However, recent SGP-based experiments have demonstrated a diminished motivation gain effect. Extending previous work with human-human partners, this experiment varied the perceived exercise ability of the SGP as a potential motivation gain effect moderator on the participant's exercise persistence. Male and female college students ( = 176; mean age, 21.5 years) completed two series of abdominal plank exercises using an exergame developed specifically for a previous Köhler study. Participants completed the exercises individually and, after a rest, were randomly assigned to complete the same exercises again alone or with one of three SGPs: low ability discrepancy partner (LP), moderate ability discrepancy partner (MP), and high ability discrepancy partner (HP). A 2 (sex) × 4 (condition) analysis of covariance main effect for Condition was not significant after controlling for Block 1 times ( = 0.093). However, contrast estimates of plank persistence times between the MP condition and individual no-partner control were significant, = 0.014, 95% confidence interval [4.34-37.68]. There were no other significant condition persistence differences. A moderate discrepancy between the participant and the superior nonhuman partner is more motivating in a conjunctive task paradigm than exercising alone or with an SGP that is low or high in ability discrepancy.
科勒效应是一种社会心理学的群体激励增益现象，已经成功地应用于基于视频的运动游戏（运动游戏）中，使用人类伙伴。然后，这项研究转向使用软件生成的伙伴（SGPs），为用户提供更大的灵活性和适应性来操作游戏环境，以使其最具激励性。然而，最近基于 SGP 的实验表明激励增益效果减弱。在之前与人合作的实验基础上，本实验将 SGP 的感知运动能力作为参与者运动持久性的激励增益效应调节变量进行了变化。男性和女性大学生（n=176；平均年龄，21.5 岁）使用专门为之前的科勒研究开发的运动游戏完成了两组腹部平板支撑练习。参与者单独完成练习，休息后，随机分配再次单独完成相同练习或与三个 SGP 中的一个完成练习：低能力差异伙伴（LP）、中能力差异伙伴（MP）和高能力差异伙伴（HP）。在控制第 1 块时间后（ = 0.093），对条件进行的 2（性别）×4（条件）协方差分析主效应没有显著差异。然而，在个体无伙伴对照条件下，平板支撑持续时间的对比估计在 MP 条件下显著， = 0.014，95%置信区间 [4.34-37.68]。没有其他显著的条件持续时间差异。在联合任务范式中，参与者与卓越的非人类伙伴之间存在适度的差异比单独运动或与能力差异低或高的 SGP 更具激励性。
