Question

Cross-Sectional, Longitudinal, and Sequential Research Designs Directions: The following list contains descriptions, challenges, and examples of cross-sectional, longitudinal, and sequential research designs. For each statement, determine which research design is being described. The researcher studies groups of participants who differ in age at the same point in time. The researcher is interested in whether frequent exposure to violent television in early childhood predicts aggressive and antisocial behavior in adulthood. May have the same problems as longitudinal and cross-sectional strategies, but the design itself helps identify difficulties. Age-related changes may be distorted because of biased sampling, participant dropout, practice effects, or cohort effects. Theoretical and methodological changes in the field can make findings obsolete. The researcher follows a sequence of samples (two or more age groups), collecting data on them at the same points in time. Does not permit the study of individual developmental trends. Age differences may be distorted because of cohort effects. The researcher is interested in age-related changes in children's problem-solving skills. The researcher selects three samples-preschool-age children, school-age children, and adolescents-and tracks them for five years. The researcher is interested in how children of different ages process traumatic events, such as terrorism or natural disasters. The researcher recruits children in grades 3, 6, 9, and 12 for the study and interviews them about the London terrorist attacks, the Asian tsunami, and Hurricane Katrina. The researcher studies the same group of participants repeatedly at different ages.

Explanation / Answer

1) this is the cross sectional study since it is happening at the same time.

2) it is longitudinal study

3) Sequential research design since it considers both
