Suppose a group of researchers wants to investigate the relationship between daily mindfulness meditation and cortisol (stress hormone) levels in the body over a 20-year time period. Which research design would allow them to measure changes with age and within individuals over time, even though it would be expensive, limited to one cohort, take a long time, and they might have people drop out of the study?

In addition, researchers can account for the possibility of cohort and/or time of measurement effects.

sequential research design

A team of researchers is interested in studying changes in parenting style over time, as children and parents grow older. One researcher states, "If we choose a ________, then it would be less time consuming and expensive. Another researcher comments, "If we choose that design, then we have measurements of parenting style for one point in time, and we can't be sure about changes with age over time." They are discussing the advantages and disadvantages of which research design?

cross sectional research design

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?

development is plastic

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?

experimental research helps establish cause and effect relationships

In a study of the effect of playing video games on sleep quality, researchers randomly assigned some participants to play an up-tempo video game for either one or three hours before bed. Other participants had no engagement with electronics in the time before bed.

In this experiment, the time spent playing video games (e.g., one or three hours) is the ________.

independent variable

There is a growing concern that Americans are not getting enough good quality sleep. A researcher hypothesizes that playing video games before bed may have something to do with this. The researcher conducts a study to randomly assign some participants to play an up-tempo video game for either one or three hours before bed. Other participants had no engagement with electronics in the time before bed. Then, the researcher assessed all the participants' sleep quality (e.g., number of awakenings, percentage of time in deep sleep) during an overnight sleep study.

Researchers wanted to study alcohol use by teenagers and observe if there were any differences between cohorts over time. They compared three groups of students (grades 6 to 8, grades 9 to 10, and grades 11 to 12) and focused on the frequency and amount of their alcohol use over a five-year period. They collected useful information about age-related changes, changes within the same individuals as they aged, and were able to account for the possibility of cohort and/or time of measurement effects. This is an example of ________.
