This paper provides an overview of the logic that underlies a sequential analytic approach to the analysis of descriptive data. Several methods for quantifying sequential relations are reviewed along with…

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…

It is very important for individuals with all kinds of developmental disabilities to learn skills in order to be independent at home. The purposes of the study were twofold; (1) to examine the effectiveness of caregiver-delivered home-based instruction using simultaneous prompting to children with moderate developmental disabilities on teaching…
