learning and motivation 2/2/22
- Animal Research * advantages: * can control genetic makeup * can control animal’s learning history * can control environment entirely * some research can’t be ethically conducted with humans * disadvantages: * animals should have rights similar to humans * findings may have limited application to humans
- How do we measure behavior? * operationalize your definitions * record behavior * rate of response / frequency * intensity / magnitude of behavior * speed of behavior, start to finish * time required for behavior to begin (latency) * interval recording - continuous intervals * time-sample recording - discontinuous intervals * topography: observing physical form of the behavior
- Assessing Reliability (repeatability) * interrater reliability: measures the degree to which 2+ coders agree
- Research Designs * experimental research - establishes cause and effect * group design: manipulate 1+ IVs across group * comparative design: independent species are dif IVs * single-subject design * pros: only need one subject, is individualized, statistical tests may not be needed to determine if there are meaningful changes in behavior, can have precise control over the variables * cons: does behavior revert to baseline after treatment is revoked? * inappropriate for situations when treatment intended to produce a long-lasting effect * ethically inappropriate to remove treatment once improvement is obtained * to get around these: use multiple baseline design
- Multiple-Baseline Design * treatment is instituted at successive points in time for 2+ persons, settings, or behaviors * pros: don’t have to return to baseline, can produce permanent change in behavior * cons: treatment effect might generalize across dif settings / behaviors before treatment instituted
