Quiz 5 Flashcards
Types of Single-Subject Designs
Extinction - when levels return to baseline after a reinforcer (treatment condition) is removed
Reversal - Actively moving behavior back toward baseline (a negative treatment condition)
ABA/ABAB design
Types of Experimental Designs
Pre-experimental, Quasi-experimental, True-experimental
True Experimental designs
matched control group; are the gold-standard, but are not always feasible (time, expense, difficulty in using control group)
Pre-experimental
no control group or untreated controls
Quasi-experimental
control group not matched to Tx group
Three Pre-Experimental Designs
- One-shot case study
- One-group pretest-posttest
- Static-group comparison
Two Quasi-Experimental Designs
- Non-equivalent control group
- Time-series
Two True experimental
- Randomized pretest-posttest control group
- Solomon randomized four-group
Efficacious treatments should have what three things
Therapeutic effect, clinical significance, and personal significance
One shot case study
One observation after a treatment
One-group pretest-posttest
within-subjects, pretest, treatment and posttest
static-group comparison
between-subjects: one group is treated, then compared to a group that didn’t receive treatment, and was not matched to the treatment group
Non-equivalent control group
groups are chosen based on convenience, not equivalence, and are thus subject to validity threats due to differential subject selection
Time-series
Within-subjects. Useful when the experimenter wants to measure the effects of a treatment over a long period of time
Randomized pretest-posttest control-group
strongest level of evidence, due to matched groups and equivalent testing conditions
