Document Summary
Roles of nature and nurture in development. Basic research methodology: methods of data collection. How can we test whether some variable has changed with age: age related research designs. Observational research: case studies, field observational studies. Correlational research: e. g. , field observational studies, e. g. , archival studies, e. g. , survey studies. Experimental research: key concepts, iv, dv, experimental control, random assignment, causation. Types of experiments: true lab experiments, quasi experiments (in lab or field), no causation, subject variables: properties of your subject. Three main designs for studying age effects: cross sectional, longitudinal, sequential. Each design can use any data collection method: surveys, observation, quasi-experimental, quasi-field experimental. Multiple subjects at one point in time. Pros: quick, cheap, demonstrates age differences. Cons: cohort effect (a group of people who were born at about the same time, same historical experiences at the same time in their lives, can say nothing about how development occurs.
