Suppose you are interested in how participants behave in different color conditions. You select 30 participants and assign them to one of three rooms. The rooms differ only with respect to the color of the walls. One room is white, one is pale blue, and a third is bright red. Each participant is served a meal of a hamburger and french fries, and you then measure how long it takes them to finish
eating. In this research, what is the dependent variable?
What will be an ideal response?

A newspaper headline reads “Intellectual pursuits key to preventing Alzheimer’s disease?” The researchers scanned the brains of healthy seniors with no memory loss and asked the seniors to recall how much reading, writing, and game-playing they did when they were growing up. The researchers found that those who reported doing daily brain activities from a young age had very low levels of amyloid plaques, which are associated with Alzheimer’s disease. The study involved fewer than 100 participants and could not account for certain factors that may have confounded the results, including socio-economic factors, diet, and overall health behaviors that might also contribute to amyloid plaque formation and Alzheimer’s risk. It also asked participants, whose average age was 76, to recall how much reading, writing, and game-playing they did when they were in elementary school, high school, and as young adults. What will be an ideal response?
