Correlational Method | determining whether 2 or more variables are related in a systematic way |
Independent Variable | the variable manipulated so that its casual effects can be assessed |
Dependent Variable | have different effects on the behavior expected to be affected |
Advantage of Experimental Design | |
Question addressed by Correlational Method | |
Cross Sectional Research Design | the performance of people of different age groups, or cohorts,are compared -provides info about age difference |
Longitudinal Research Design | the performance of one cohort of individuals is assessed repeatedly over time -same individuals are studied as they develop |
Sequential Research Design | combines the cross-sectional and longitudinal approach in a single study |
Longitudinal Research Design example | study of development of vocab |
Sequential Research Design Can Tell What 1 | ~ age-related trends are truly developmental in nature & reflect how it can be expected to change over time |
Sequential Research Design Can Tell What 2 | ~age trends differ from cohort to cohort & suggest that each generation is affected by its distinct growing-up experiences |
Sequential Research Design Can Tell What 3 | ~ which trends suggest that events during a specific period of history similarly affect all cohorts at the time |
