In a research study on the multi-store model of memory, scientists found that as subjects spend more time rehearsing learned information, the more information they are able to recall on a retrieval task. What type of research is described in this scenario? A. Case study
B. Correlational study
C. Experiment
D. Naturalistic observation
The correct answer is C. Experiment.
In this scenario, scientists are manipulating the variable of rehearsal time to observe its effect on memory recall, which is a hallmark of experimental research. Experimentation allows researchers to establish cause-and-effect relationships by systematically varying one factor (rehearsal time) and measuring its impact on another (amount recalled).
