A variable that may influence the outcomes of stimulus preference assessments (SPAs) is whether social interaction is provided during the stimulus access period. In Experiment 1, we compared the outcomes of a Solitary paired stimulus preference assessment (PSPA) (toys only), Social PSPA (toys plus social interaction), and Combined PSPA (toys alone and toys plus social interaction) to determine whether the addition of social interaction influenced preference for toys in preschool children. In Experiment 2, we conducted a concurrent-operant reinforcer assessment to compare the reinforcing efficacy of stimuli with and without social interaction. Experiment 1 showed preference for toys was stable across assessments (Solitary and Social PSPAs) and most participants preferred toys plus social interaction when compared in a single assessment (Combined PSPA). Experiment 2 showed that results of the Combined PSPA in Experiment 1 predicted the outcome of most participants' reinforcer assessments.

评估社交互动对休闲项目偏好评估结果的影响

可能影响刺激偏好评估（SPA）结果的一个变量是在刺激访问期间是否提供社交互动。在实验 1 中，我们比较了单独配对刺激偏好评估 (PSPA)（仅限玩具）、社交 PSPA（玩具加社交互动）和组合 PSPA（单独玩具和玩具加社交互动）的结果，以确定是否添加社会互动影响学龄前儿童对玩具的偏好。在实验 2 中，我们进行了并发操作性强化物评估，以比较有和没有社会互动的刺激的强化效果。实验 1 显示，对玩具的偏好在各个评估（单独和社交 PSPA）中是稳定的，并且在单一评估（组合 PSPA）中进行比较时，大多数参与者更喜欢玩具和社交互动。实验 2 表明，实验 1 中组合 PSPA 的结果预测了大多数参与者强化物评估的结果。
