Chapter 7 – Cooper ABA

Term Definition
Correlation When systematic variation between 2 events is found and can be used to predict the relative probability that one event will occur, based on the presence of the over event
Experimental Control When a predictable change in behavior can be reliably produced by the systematic manipulation of some aspect of the individual’s environment (analysis dimensions of the 7 Dimensions of ABA)
Internal Validity The extent to which an experiment convincingly shows that changes in behavior are a function of the IV and not the result of uncontrolled or unknown variables
Confounding Variables
4 Important Elements of Behavior Behavior is:
• Individual
• Continuous
• Determined
• Behavior variability if extrinsic to the organism
6 Components of Experiments in Applied Behavior Analysis 1. At least 1 subject
2. At least 1 behavior (DV)
3. At least 1 setting
4. At least 1 treatment
5. A measurement system and ongoing analysis of data
6. An experimental design
Experimental Question
Single-Subject Design
Dependent Variable
Experimental Control
Extraneous Variables
Independent Variable
Experimental Design
Parametric Analysis
Steady/Stable State Responding A pattern of responding that exhibits very little variation in its measured dimensional quantities over a period of time
Baseline Logic Refers to experimental reasoning inherent in single-subject experimental designs
3 Parts of Baseline Logic 1. Prediction
2. Verification
3. Replication

Each of these elements depends on an overall experimental approach called steady state strategy

Steady State Strategy Repeated exposure of a given subject to a given condition while trying to eliminate extraneous influences on behavior & obtaining a stable pattern of responding before introducing the next condition
Stable Baseline
Ascending Baseline/ Descending Baseline
Variable Baseline
Practice Effects
Affirmation of the Consequent
5 Main Experimental Designs 1. Multiple Baseline
2. Changing Criterion
3. Reversal
4. Alternating Treatments
5. Withdrawal
Alternating Treatments Design Rapid alteration between 2 or more treatments
Multiple Baseline Design Staggered implementation of the intervention in a step-wise fashion across subjects, settings, or behaviors
Reversal (withdrawal) Design Alternation between baseline and a particular intervention
Changing Criterion Design Reinforcement or punishment is contingent upon a certain level of behavior, which changes in a step-wise fashion
