Question

7/ The results of an experiment on the effects of sleep training on sleep quality showed that participants who received eight sessions of sleep enhancement training had longer sleep duration and better sleep quality than participants who did not receive the training. This led the researchers to conclude that an eight-week sleep enhancement training program is effective for improving sleep quality. What advantage of experimental research does this demonstrate? Multiple Choice Question Experimental research helps establish cause and effect relationships. Experimental research reviews media (e.g., old texts, pictures) to explore patterns in behavior. Experimental research allows the researcher to serve as a participant in the study. Experimental research uncovers as much as possible about a single person or situation. 8/ A research team designed a study of parenting style that included three groups: parents in their 30s with preschool-age children (2-5), parents in their 40s with children ages 6-11, and parents in their 50s with adolescents ages 12-18. This design is considered by the researchers to be less-time consuming and expensive than other potential designs, but they acknowledge the limitation of having only one measurement of parenting style for one point in time. As such, they cannot conclude that changes between parent groups indicate changes with age over time. Which research design does this describe? Multiple Choice Question Cross-sectional research design Cohort sequential research design Sequential research design Longitudinal research design 9/ College students are often recruited for research studies of young adult development, but this is often discussed as a limitation of those studies.
