Kristina Willett applied behavior analysis II 11/26/2013 unit 6 assignment Kristina Willett applied behavior analysis II 11/26/2013 unit 6 assignment Case Study 1: Martin Martin, a behavior analyst, is working with Sara, a 14-year-old girl with severe developmental delays who exhibits self-injurious behavior (SIB). The self-injurious behaviors included pulling her hair, biting her arm and banging her head against the wall. After conducting a functional analysis, Martin decided to employ an intervention program consisting of differential reinforcement of other (DRO) desired behavior. Martin collected data on Sara's SIB before and during the intervention. Below is a depiction of the data that Martin collected: Sara’s Frequency of SIB | BASELINE Occurrences | DRO Occurrences | 22 | 5 | 25 | 5 | 27 | 3 | 26 | 2 | 1. Create a basic line graph using Microsoft Excel, to be included in your Word document. The graph should depict the data provided in this case study. You should only need to create one graph, with SIB depicted, both in baseline and in intervention. 2. What type of research design did Martin employ when working with Sara? It is my opinion that Martin used the Interval recording procedure for collecting data pertaining to Sara’s self-injurious behaviors. The Interval recording procedure involves observing and recording the occurrence and nonoccurrence of behaviors at predetermined units of time (i.e., intervals ranging from several seconds to several minutes or even hours). The research design that Martin implemented when working with Sara is the A-B Design. The A-B Design is a two phase design consisting of a no-intervention baseline phase (A) and an intervention phase (B). It allows for evaluation of pre-intervention and intervention problem status. It is a quasi-experimental design (Cooper & Howard,
