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

Prediction
Verification
Replication
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
Baseline
Stable Baseline
Ascending Baseline/ Descending Baseline
Variable Baseline
Prediction
Practice Effects
Affirmation of the Consequent
Verification
Replication
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
