Age Differences in Children's Choice Behavior: The Impact of Available Alternatives
研究了4至12岁儿童在面临选项增加时的选择行为差异，发现年龄较小的儿童与年龄较大的儿童对选择集扩大的反应不同，部分原因在于他们运用相似性判断的能力存在差异。
The authors examine how children of different ages respond to the addition of new alternatives into an existing choice set. Children 4 to 12 years of age made choices from an initial and an expanded set of products using a modified constant sum allocation procedure. The findings indicate that younger children respond differently than older children to the expansion of choice sets and that this pattern is related, in part, to age differences in children's ability to incorporate similarity judgments into the choice process.
