Which aspect of the scientific method does this demonstrate?
The scientific method facilitates the establishment of a literature or knowledge base.

development is plastic
A researcher is interested in studying the relationship between sensitivity to negative information over positive (i.e., negativity bias) and hours of sleep at night (i.e., average total sleep time). Correlational research would allow this researcher to ________.

Development is multidirectional.
Researchers conducted an experiment to study the effects of sleep training on sleep duration and quality. They randomly assigned some participants to a treatment condition where they received eight sessions of sleep enhancement training and some participants to a control condition where they did not receive the training. If the participants who received sleep enhancement training had better sleep duration and quality than the people who did not receive the training, then the researcher can conclude that the training works. What advantage of experimental research does this demonstrate?
Experimental research helps establish cause and effect relationships.
Suppose a group of researchers wants to investigate the relationship between daily mindfulness meditation and cortisol (stress hormone) levels in the body over a 20-year time period. Which research design would allow them to measure changes with age and within individuals over time, even though it would be expensive, limited to one cohort, take a long time, and they might have people drop out of the study?
Longitudinal research design
