Document Summary

Research methods: themes and research methods in developmental psychology & ethics in research. Observational research - used to observe behaviour in a natural habitat. These studies are not manipulated by the researcher. Correlational research - correlations can be either positive (+1) or negative (-1) Survey studies (child"s intellectual abilities), archival studies, retrospective studies. A negative correlation = as one thing increases another decreases- vice versa ex) as age increases, skin elasticity decreases, resulting in wrinkles. A positive correlation = as one thing increases, the defendant variable also increases ex) as outside temperature rises, the incidence of aggression/violence rises also. Age-related studies: used to determine whether a variable has changed (or not) with age. Experimental research: involves measurement of the dependant variable in terms of the independent variable and random assignment into control/non-control groups. ** if you cant randomly assign, you can"t prove causation. Quasi-experiments - random assignment not possible for at least one variable.
