I’m working on a Psychology question and need guidance to help me study.

• Watch the Unit 9 Lecture. (Click here for transcripts)
• Read the following scenario.

Visit the Purdue Global Library: Using Publication Finder search bar, search for the Journal of Applied Behavior Analysis. Then, search within the Journal of Applied Behavior Analysis for one of the research designs you read about this week. The article must use an ABAB design, a multiple baseline design, an alternating treatments design, or a changing criterion design to evaluate a behavior intervention.

Your search should return a number of articles. You are looking for an article that used one of the research designs we have covered to evaluate the effectiveness of an intervention. You are not looking for an article just on the research design. Review the titles to find a topic that is of interest to you. Read the article. Then, in your Discussion Board post, complete the following:

• Briefly describe the intervention that was used by the researchers. What is the independent variable? What was the dependent variable (the behavior being measured)?
• Briefly describe the research design used in the study.
• Identify how this research design demonstrates a functional relationship between the intervention and the dependent variable (the target behavior).
• Were these researchers able to demonstrate a functional relationship?
• Make sure to include a full APA formatted reference for the article you chose.

Peer Responses:

Review two of your classmates’ posts to assess the following:

• Describe one possible threat to interval validity and one possible threat to external validity that applies to the research described by your peer.
