THE DEVELOPMENT OF DECISION MAKING

一个信息处理模型的发展决策将 制定和测试。 该模型强调决策的偶然性 根据决策任务的结构制定策略。 给定一个复杂的 任务，决策者将通过使用较少的相关 环境中可用的信息。 年龄较大的儿童和 成年人，然而，预计将采用更复杂的策略， 比年幼的孩子更容易获得相关信息。 中使用的信息 7岁，10岁和大学生的决策将是 通过要求他们在两个选择之间做出决定来评估 有随机的结果导致损失和收益。 A受试者内 将使用不同收益、损失和概率的析因设计， 评估每个主题对这些信息维度的敏感性。 在第二项研究中，类似的受试者群体将在两个方面做出决定。 简单（2种选择）和复杂（4种选择）任务，以评估 任务复杂性对决策策略的影响。

An information processing model for the development of decision making will be formulated and tested. The model stresses the contingency of decision making strategies on the structure of the decision task. Given a complex task, decision makers will simplify it by using less of the relevant information that is available in the environment. Older children and adults, however, are expected to employ more complex strategies using more of the relevant information than younger children. The information used in decision making by 7-year-olds, 10-year-olds, and college students will be assessed by requiring them to make decisions between pairs of alternatives having random outcomes leading to losses and gains. A within subject factorial design varying gains, losses, and probabilities will be used to assess the sensitivity of each subject to these dimensions of information. In a second study, similar groups of subjects will make decisions in both simple (2 alternative) and complex (4 alternative) tasks to assess the effect of task complexity on decision making strategy.
