Descriptive observations were conducted to record problem behavior displayed by participants and to record antecedents and consequences delivered by caregivers. Next, functional analyses were conducted to identify reinforcers for problem behavior. Then, using data from the descriptive observations, lag-sequential analyses were conducted to examine changes in the probability of environmental events across time in relation to occurrences of problem behavior. The results of the lag-sequential analyses were interpreted in light of the results of functional analyses. Results suggested that events identified as reinforcers in a functional analysis followed behavior in idiosyncratic ways: after a range of delays and frequencies. Thus, it is possible that naturally occurring reinforcement contingencies are arranged in ways different from those typically evaluated in applied research. Further, these complex response-stimulus relations can be represented by lag-sequential analyses. However, limitations to the lag-sequential analysis are evident.
进行描述性观察，以记录参与者表现出的问题行为，并记录照顾者提供的前因和后果。接下来，进行功能分析以确定问题行为的增强物。然后，使用描述性观察的数据，进行滞后序列分析，以检查问题行为发生时环境事件发生的概率随时间的变化。滞后序列分析的结果根据功能分析的结果进行解释。结果表明，在功能分析中确定为增强物的事件以特殊的方式跟随行为：在一系列延迟和频率之后。因此，自然发生的强化事件可能以与应用研究中通常评估的不同方式安排。此外，这些复杂的反应-刺激关系可以通过滞后序列分析来表示。然而，滞后序列分析存在明显的局限性。
