The study examines the typicality effect in Spanish-English bilingual children and adults in their 2 languages.
Two studies were conducted using a category-generation task to compare the typical items generated by children with those generated by adults. Children in the 1st study differed orthogonally with respect to age (older, younger) and language use (higher Spanish use, higher English use). In the 2nd study, the older and younger children were matched with adults on their current Spanish use to delineate the influence of test language and age.
Children with higher English use generated more typical items, and these occurred earlier in their word lists in English than in Spanish. Participants at all levels of Spanish experience generated fewer typical items in Spanish than in English. Thus, there was less convergence of items considered typical among participants in Spanish. Older and younger children did not differ in the number of typical items generated. However, when participants were matched for language use, older children produced typical items earlier in their word lists than did younger children.
This study demonstrates the influence of language use and test language in generation of typical items in bilingual children.

本研究考察了西班牙语-英语双语儿童和成人在两种语言中的典型性效应。
进行了两项研究,使用类别生成任务来比较儿童和成人生成的典型项目。第一项研究中的儿童在年龄(较大、较小)和语言使用(较高的西班牙语使用、较高的英语使用)方面相互正交。在第二项研究中,根据当前的西班牙语使用情况,将年龄较大和较小的儿童与成人进行匹配,以确定测试语言和年龄的影响。
英语使用较多的儿童生成了更多典型项目,并且这些项目在他们的英语单词列表中比在西班牙语单词列表中出现得更早。所有西班牙语水平的参与者在西班牙语中生成的典型项目都比在英语中少。因此,在西班牙语中,参与者之间认为典型的项目的一致性较低。年龄较大和较小的儿童在生成的典型项目数量上没有差异。然而,当参与者在语言使用上匹配时,年龄较大的儿童在他们的单词列表中比年龄较小的儿童更早地生成典型项目。
本研究证明了语言使用和测试语言对双语儿童典型项目生成的影响。
