In single-subject rearch designs, each subject serves as his or her own control
Practice effect
- to have occurred when performance improves due to repeated opportunities to engage in the behavior during baseline
Methology of behavior analysis is guided by the principle Determinism. Behavior analysts assume that behavior is lawful and determined; that is, all behavioral phenomena occur in relation to other environmental events.
Experimental Design
- refers to how the independent variable is manipulated during a study.
- refers to the sequence and form of independent variable manipulations in a study.
- onle one variable should be changed at a time in an experiment in order to maintain experimental control and demonstrate internal validity.
- comprised of (a) at least one subject, (b) at least one dependent variable, (c) at least one setting, (d) at least one independent variable, (e) a standardized measurement system, (f) and experimental design.
- IV is manupulated by the experimenter
- DV is observed and measured, not manupulated.
- measurement procedures and observations must be conducted in a standarized manner is order to demonstrate Internal Validity and support replication of the study by future researchers.
Experiments are used to achieve the highest level of scientific understanding, control #causation
Experimental Question
- a specific statement of what the researcher wants to learn from their experiment
Experimental control
- achieved when a predictable change in behaivor(DV) can be reliably produced by the #systematic manipulation of some aspect of the environment(IV) #analytic #functionalRelation
The target behavir is an experiment is known as the dependent variable.
Treatment should only be implemented once baseline responding is stable. This is the best way to demonstrate experimental control/internal validity.
Types of baseline responding patterns: ascending, descending, variable, and stable.
Confounding variables
- refer to variavles which were #uncontrolled for but supected to have exerted an influence on the dependent variable.
Baseline logic : Prediction, verification, and replication
Verification
- behavior returns to the previously predicted level of baseline responding by termination, or withdrawal, of the independent variable.
