In another version of the multiple-baseline design, multiple baselines are established for the same participant but for different dependent variables, and the treatment is introduced at a different time for each dependent variable. Practice: Create a graph that displays the hypothetical results for the study you designed in Exercise 1. This pattern of results strongly suggests that the treatment was responsible for the changes in the dependent variable. Winifred worked with two children with autism who engaged in self-injurious behavior (SIB) involving head-slapping. Definition: An experimental design where the initial baseline phases are followed by a series of treatment phases consisting of successive and gradual changing criteria for reinforcement or punishment. During the first phase, A, a. baseline. Other acquisitions were also made for consideration of $204 million making a total of$13,963 million (net of cash acquired) for the year. This means plotting individual participants data as shown throughout this chapter, looking carefully at those data, and making judgments about whether and to what extent the independent variable had an effect on the dependent variable. In visually inspecting their data, single-subject researchers take several factors into account. This could mean that the positive attention had a lasting effect on the students studying, which of course would be good. ), Figure 10.1 Results of a Generic Single-Subject Study Illustrating Several Principles of Single-Subject Research. Which type of chromosome region is identified by C-banding technique? But if the dependent variable changes with the introduction of the treatment and then changesbackwith the removal of the treatment (assuming that the treatment does not create a permanent effect), it is much clearer that the treatment (and removal of the treatment) is the cause. Three basic types of multiple baseline design are (a) multiple baseline across different behaviors of the same subject, (b) multiple baseline across the same behavior of different subjects, and (c) multiple baseline of the same behavior of one subject across different settings.
