Discussion topic 1 of 1
In this unit you learned about four different comparison designs. Using the behavior and intervention you described in before, choose one of the comparison designs and apply the behavior and intervention to it. For example, you may want to compare the original intervention chosen to a second intervention, or you may want to investigate procedural integrity of the original intervention. In your presentation make sure to include a discussion of the internal validity for the specific comparison design you chose.

I described this

John is 15 years old boy who lives in Seattle with his mother Maria, his father Erick and his sister Clare. The family has lived in Seattle for the past 10 years. He was born in Mexico, and he speaks and understands some Spanish and sometimes prefers to be given direction in Spanish. In school, he is spoken to in English!

Past psychiatric history
John's parents become concerned when he stopped talking and would hide from people who did not know! He was diagnosed with Autism at 3.5 years old.

Behavior -Picking hands and fingernails
Topographical definition- any instance of using hands, mouth or objects to make contact with a finger or toe nails, with enough force to remove any part of the nails or skin.

Measure & Criteria to discontinue targeting - frequency and duration

Hypothesized Function- Sensory
Intensity key 1=Makes contact; 2=takes piece of nail off; 3 =takes pieces of nail or skin off; 4=enough to cause bleeding.

When the behavior is put on extension-this behavior no longer produces reinforcement.

A-imperfection of the nail; B-biting nail; C–imperfection is done.

Tracker every time you see imperfection, you use a nail clipper.

Comparative designs can be described as experimental designs that allow researchers to determine which intervention is more effective or efficient for changing the target behavior by comparing them (Gast & Ledford, 2014). The terms “baseline” and “intervention” may be somewhat ambiguous in comparative designs. To select comparative design, researchers must decide on: research question(s), whether target behavior is reversable, time available for study, number of participants and likely threats (Gast & Ledford, 2014). The comparative design subtype used in this study is called the multitreatment design.
The multitreatment design is a flexible experimental design with sequential introduction and withdrawal of treatments, which allows comparisons between two treatments and comparisons between baseline and one treatment...
