We explored the effect of controlled and autonomous learning choices on the consumption of a high-energy snack food, and also examined whether snack consumption during a controlled choice learning activity could 'up-regulate' subsequent performance on a self-regulation task. Participants were randomly assigned to a controlled choice learning condition in which food was provided, a controlled choice learning condition in which food was not provided, or an autonomous choice learning condition in which food was provided. Results indicated that the autonomous choice group consumed significantly less snack food than the controlled-choice-and-food group. Participants in the autonomous choice condition also performed better on the subsequent self-regulation task than the controlled-choice-and-food group, even after controlling for the amount of food consumed. Furthermore, within the controlled-choice-and-food condition, there was no association between food consumption and subsequent self-regulation task performance. Discussion focuses on the potential impact of a controlled learning climate on snack food consumption and on the degradation of self-regulation capacities.
我们探讨了控制型和自主型学习选择对高能量零食消费的影响，还研究了在控制型选择学习活动期间吃零食是否能“上调”随后的自我调节任务表现。参与者被随机分配到一个提供食物的控制型选择学习条件、一个不提供食物的控制型选择学习条件，或一个提供食物的自主型选择学习条件。结果表明，自主选择组比控制型选择和食物组消耗的零食明显更少。即使在控制了食物摄入量之后，自主选择组的参与者在随后的自我调节任务中表现也优于控制型选择和食物组。此外，在控制型选择和食物组中，食物消费与随后的自我调节任务表现之间没有关联。讨论重点关注了受控学习环境对零食消费和自我调节能力下降的潜在影响。
