Study Notes
Importance of Individual Subject
- Focus on individual subjects allows for tailored interventions targeting socially significant behaviors.
- Group-comparison approaches can mask individual variability in performance.
Groups-Comparison Experiment
- Involves random selection of subjects into experimental and control groups.
- Standard procedure includes pretest, application of independent variable, and posttest.
Limitations of Group Data
- Group averages can hide individual fluctuations; some may improve while others do not.
- Understanding treatment effectiveness is crucial at an individual level rather than just the group average.
Experimental Design Flexibility
- Researchers must ensure each experimental design is tailored to its specific research question.
- Effective design manipulates independent variables to yield convincing data.
Experimental Designs
- Multiple analytic tactics can be combined in designs, promoting varied experimental setups.
- Continuous evaluation of individual data aids in prediction, verification, and replication.
Internal Validity
- High internal validity indicates a clear functional relationship demonstrated by the experiment.
- Must control relevant variables to avoid confounding, which threatens internal validity.
Subject and Setting Confounds
- Maturation effects can alter subjects' performance over time.
- Natural settings may introduce more confounding variables compared to controlled environments; changes necessitate capping new conditions until steady responding is established.
Assessing Social Importance of Behavior Changes
- Outcomes can be assessed through comparisons to normative samples, standardized tests, and expert evaluations.
- Direct assessments in natural environments promote maintenance and generalization of behavior changes.
Normative Samples
- Ongoing measurements against normative samples allow for continuous tracking of behavioral improvements.
Role of Consumers and Experts
- Consumer feedback is a common method for assessing social validity.
- Experts can evaluate the significance of behavioral changes.
Standardized Testing
- Tools like the Self-Injury Trauma Scale (SITS) serve as examples for assessing performance validity in real-world conditions.
External Validity
- Refers to the generalizability of a study's findings under different conditions and populations.
- Stronger generality implies greater contribution to the field of applied behavior analysis.
Evaluating Internal Validity
- Requires scrutiny of measurement systems, experimental designs, and potential confounds.
- Visual analysis is favored for evaluating behavior change over mere statistical significance.
Visual Analysis and Statistical Errors
- Type I error (false positive) occurs when an effect is claimed to exist when it does not.
- Type II error (false negative) happens when it fails to identify an effect that exists.
- Visual analysis minimizes Type I errors while statistical approaches may increase them.
Social Validity Considerations
- Evaluate independent variables based on acceptability, complexity, practicality, cost, and generalization of behavior changes.
Theoretical Significance
- Studies should be analyzed for their scientific merit and contributions to behavioral science, promoting "knowledgeable reproducibility."
Need for Conceptual Understanding
- Emphasizes the importance of grasping underlying principles for successful behavior change demonstrations.
- Calls for heightened attention to technology, result interpretation, and conceptual integrity in experimental reporting.
