许多日常行为都是隐含的赌博，因为我们视觉系统中的不精确性决定了我们成功或失败的可能性。选择最佳的行动策略涉及到通过相应的概率来衡量潜在结果的成本和收益，并且需要对自己的不精确性进行稳定的表示。这种能力是如何在儿童期视觉技能发生剧烈变化的发育过程中获得的尚不清楚。在一项奖励性的快速达成任务中，6至11岁的儿童遵循“风险寻求”策略，导致过高的失分。相比之下，成年人的表现接近最佳。儿童的错误不能解释为价值或概率的扭曲估计，但可能反映了不同的行动选择标准或不成熟的价值和概率信息的整合，而规划运动。这些发现为理解儿童在日常视觉环境中的冒险行为提供了一个起点，因为次优选择可能是危险的。此外，儿童的危险视觉决策反映了非运动赌博的报告，提高了跨决策领域发展的共同过程的可能性。
Many everyday actions are implicit gambles because imprecisions in our visuomotor systems place probabilities on our success or failure. Choosing optimal action strategies involves weighting the costs and gains of potential outcomes by their corresponding probabilities, and requires stable representations of one's own imprecisions. How this ability is acquired during development in childhood when visuomotor skills change drastically is unknown. In a rewarded rapid reaching task, 6‐ to 11‐year‐old children followed ‘risk‐seeking’ strategies leading to overly high point‐loss. Adults' performance, in contrast, was close to optimal. Children's errors were not explained by distorted estimates of value or probability, but may reflect different action selection criteria or immature integration of value and probability information while planning movements. These findings provide a starting point for understanding children's risk‐taking in everyday visuomotor situations when suboptimal choices can be dangerous. Moreover, children's risky visuomotor decisions mirror those reported for non‐motor gambles, raising the possibility that common processes underlie development across decision‐making domains.
