We compared responding to joint attention (RJA) in younger siblings of children with ASD (SIBS-ASD; n = 46) and younger siblings of children developing typically (SIBS-TD; n = 35). Children were tested between 12 and 23 months of age in a situation in which an experimenter directed the child's attention to one of 8 targets. Each child responded to 10 different combinations of verbal and nonverbal cues containing varying levels of attention-specifying information. SIBS-ASD had significantly lower overall RJA scores than SIBS-TD. Moderately redundant cues were most difficult for SIBS-ASD relative to SIBS-TD; adding a point to moderately redundant cues improved RJA for SIBS-ASD, bringing them to a level of RJA commensurate with SIBS-TD.
我们比较了患有自闭症谱系障碍儿童的年幼兄弟姐妹（自闭症谱系障碍儿童的兄弟姐妹组，n = 46）和发育正常儿童的年幼兄弟姐妹（正常发育儿童的兄弟姐妹组，n = 35）对共同注意的反应（RJA）。在12至23个月大的儿童中进行测试，实验者将儿童的注意力引导至8个目标之一。每个儿童对包含不同水平注意力指定信息的10种不同的语言和非语言线索组合做出反应。自闭症谱系障碍儿童的兄弟姐妹组的总体RJA得分显著低于正常发育儿童的兄弟姐妹组。相对于正常发育儿童的兄弟姐妹组，中等冗余线索对自闭症谱系障碍儿童的兄弟姐妹组来说最难；给中等冗余线索加一分可提高自闭症谱系障碍儿童的兄弟姐妹组的RJA，使其达到与正常发育儿童的兄弟姐妹组相当的RJA水平。
