计算机序贯事件抽样决策任务管理的187个5至10岁的儿童和成人参与者之间的选择，不同的获胜概率（研究1）或输赢概率（研究2）的一系列选择。使用了直观和更明确的措施。研究我发现，在不同年龄段，参与者表现出直觉的敏感性概率;然而，成年人的参与者表现出更大的敏感性比儿童，和年幼的儿童未能表现出更明确的理解概率。研究2还表明，儿童直觉上对概率敏感;然而，包括损失对决策过程的影响有限。这些发现及其相关的认知发展理论进行了讨论。(c)2007爱思唯尔公司All rights reserved.
A computerized sequential event sampling decision-making task was administered to 187 5- to 10-year-olds and adults Participants made a series of choices between alternatives that differed in win probability (Study 1) or win and loss probability (Study 2). Intuitive and more explicit measures were used. Study I revealed that, across ages, participants demonstrated intuitive sensitivity to probability; however, adult participants evidenced greater sensitivity than did children, and younger children failed to demonstrate more explicit understanding of probability. Study 2 also revealed that children were intuitively sensitive to probability; however, the inclusion of loss had limited impact on decision processes. These findings and their relevance to cognitive developmental theory are discussed. (c) 2007 Elsevier Inc. All rights reserved.
