Psych Research Pt 9
Time Series & Single Subject Designs
| Question | Answer |
|---|---|
| Time-Series Design | a quasi-experiment in which the performance of one group of subjects is measured both before and after an experimental treatment |
| Single Group, Pre-test, Post-test Design | one group of subjects tested only once before and after treatment |
| Interrupted Time-Series Design | one group of subjects tested more than once before and after treatment |
| Non-Equivalent Before-After Design | two non-randomly assigned groups of subjects and DV is pretest minus posttest |
| Ex Post Facto Design | a research design in which the researcher uses archival data to study an event that occurred in the past |
| Reversal Design | subject's behavior is recorded prior to treatment, then treatment, behavior measured again, treatment withdrawn to see if behavior reverses back to pre-treatment levels, then treatment reintroduced (1 treatment for 1 behavior) |
| Multielement Design | several treatments for one behavior |
| Multiple Baseline Design | several different behaviors are recorded w/ one treatment for each |
| Problems w/ All Single Subject Experimental Designs | likely chance of both type I and type II errors, placebo effects, experimenter bias, generalization difficulties |
