Research Design 1. Research methods in developmental psychology A. The Scientific Method: a value that says we have to be objective and let the data determine if the theory has/does not have merit *Examples are not data B. Selecting a sample -Sample a subgroup out of the larger population of children -Generalization idea that the results of your study will be able to generalize beyond the particular children that you studied - All abused/3 yr. olds/etc. -Need to pick a sample that is broad, diverse -Varied incomes, environments, genetics, advantages, etc. -Classic studies may have been flawed in terms of broad generalization -Large studies funded by special interest groups, gov. strict guidelines C. Necessary qualities for data collection strategies -Reliability - the extent to which a measure yields consistent results both over time and across observers a. Temporal stability the extent to which a measure gives you similar results at 2 points in time which are close together -Use same coding scheme/measure/strategy (ex: observational) with same research participants -Would expect fairly comparable results; if not, measure is flawed b. Interrater reliability the extent to which two raters obtain similar data when they use the same measure on the same individual at the same time -Need to be objective -Validity = the extent to which a measure accurately reflects what the researcher intended to measure -ex: need to define aggression, intelligence, etc. to show what you’re looking for D. Data collection strategies: can be combined in the duration of one study -Self report ask children to tell you about themselves
