In this study, removal of a transitional object (pillow) was applied as the sole intervention for one of two siblings who sucked their thumbs. The intervention was applied only to the older sibling, whereas data were collected on the thumb sucking of both participants. Results indicated that removal of the transitional object for the older sibling reduced thumb sucking in both siblings and increased thumb sucking when the pillow was reintroduced. Discussion focuses on possible explanations for the effects of the intervention across both participants and the limitations of this study.
在本研究中，去除一个过渡性物品（枕头）被用作对两个吮拇指的兄弟姐妹中一人的唯一干预措施。该干预仅应用于年长的兄弟姐妹，而对两名参与者的吮拇指情况都进行了数据收集。结果表明，去除年长兄弟姐妹的过渡性物品减少了两名兄弟姐妹的吮拇指行为，而当重新引入枕头时，吮拇指行为增加。讨论集中在对该干预措施对两名参与者产生影响的可能解释以及本研究的局限性。
