E N D
ID participant • Barb- stressed out mature woman • Health episode derailed exercise • Anxious to resume activity levels
ID and Define a Target Behavior • Sustained walking • Increase from a mere 10 minutes without fatigue to 60 minutes of vigorous activity • Trail or Treadmill? • Incentive? • Antecedent?
Technique to Measure • Duration • To increase time spent engaged in meaningful activity • Will record minutes per day • Goal: To increase each days minutes spent walking by 5 minutes to reach goal of 60 minutes of sustained walking
AntecedentOr, the incentive to move! • What can be done to insure that the behavior will occur? • Yoga! • 15 minutes of daily stretching • Also serves as the reinforcer- the more you move, the more you can move.

Intervention:Premack Principal Yoga stretchesIndependent Variable
Report Occurrence of Target Behavior • Behavior recorded for two weeks after intervention • Walking Increased incrementally daily • Mean of Target Behavior after intervention– 25.6 minutes • Graph Data Points for Behavior after intervention - 15
Design of intervention • AB Design chosen for speed and fast results • Only 2 phases- baseline and intervention • ABAB would have established functional relationship between dependent and independent variables. • ABAB gives more descriptive and predictive information.
What could go Wrong? • Selected inappropriate design • Unable to establish functional relationship • Unable to be replicated • Trendline too varied • Too much variability • 100% overlap • Intervention and independent variable is also the reinforcer??? • What was I thinking?
What Went Right? • Quick Results • Easy charting • Behavior increased! • Well Being increased! • Learned recording, selecting and graphing intervention techniques
Was it a successful intervention? • The data is insufficient to state that the intervention is the cause of the improved behavior. • The Behavior improved.
