This study examined the effects of variant versus invariant high-probability (high-p) request sequences on the performance of requests to initiate a social bid by young children with emotional-behavioral disorders. In the initial phases of the investigation, a multiple baseline design showed that the delivery of invariant sequences (i.e., high-p requests delivered in the same sequence) produced initial increases in compliance to requests to initiate a social bid to a peer. However, increases were not maintained across the invariant condition. The delivery of variant high-p sequences produced increases in compliance to requests to initiate social bids that were maintained across the variant condition. In a follow-up condition, the number of requests within the pool of the variant and invariant high-p requests were controlled. Results of the follow-up condition replicated those found in the initial condition. Implications for applied use and future research are discussed.
本研究考察了可变与不变的高概率（高p）请求序列对患有情绪行为障碍的幼儿发起社交邀请请求表现的影响。在调查的初始阶段，多重基线设计表明，不变序列（即以相同顺序发出的高p请求）的呈现使对向同伴发起社交邀请请求的依从性最初有所提高。然而，在不变条件下，这种提高未能持续。可变高p序列的呈现使发起社交邀请请求的依从性提高，且在可变条件下得以维持。在后续条件中，对可变和不变高p请求库中的请求数量进行了控制。后续条件的结果重复了初始条件中的发现。文中讨论了其应用意义及未来研究方向。
