The relative reinforcing value of toys was assessed in the absence of, and immediately following, participant observation of a peer manipulating one of the toys. Preference assessments were used to identify preference hierarchies. Reinforcer assessments were conducted with a high-preference item, a low-preference item, and a control. Each participant allocated responding toward the high-preference item during baseline. When reinforcer assessment sessions were preceded by a peer observation period, 3 of the 4 participants shifted allocation to the toy manipulated by the peer. The 4th participant shifted allocation only when the high-preference stimulus was replaced with a medium-preference stimulus. These data suggest that, among preschoolers, response allocation is influenced by observations of peers playing.
在没有同伴对其中一个玩具进行操作的情况下以及同伴操作玩具后立即对玩具的相对强化价值进行了评估。使用偏好评估来确定偏好等级。对一个高偏好项目、一个低偏好项目和一个对照物进行强化物评估。在基线期，每个参与者都将反应分配到高偏好项目上。当强化物评估阶段之前有一个同伴观察期时，4名参与者中有3名将分配转向了同伴操作的玩具。第4名参与者仅在高偏好刺激被中等偏好刺激取代时才改变分配。这些数据表明，在学龄前儿童中，反应分配会受到同伴玩耍观察的影响。
