A cross-sectional research design involves testing multiple groups of individuals who differ in age at the same point in time. This allows for comparisons across age groups and is useful for studying developmental changes. Longitudinal research design involves testing the same individuals over a period of time, and multifactorial research design involves manipulating multiple variables to determine their effect on an outcome. Habituation research design typically involves measuring an organism's response to a repeated stimulus over time.
