When 75-year-old Ross discusses what he thinks about war, he often cites World War II. 62-year-old Joey tends to give examples form the Korean War. 50-year-old Chandler tends to talk about the Vietnam War. Their views on war, and the examples they choose, illustrate the enduring effects of:

A developmental researcher is conducting an experiment on whether engaging in cognitive activities, such as crossword puzzles, helps to reduce the risk of Alzheimer’s disease in adults. The independent variable is [BLANK-1].

A political consultant is working for a candidate to determine what will influence the candidate’s popularity in the voting district. Rather than using a poll, the consultant brings together sets of voters in groups of 10-12 to hear their concerns. This type of method is known as a(n) [BLANK-1].

A man in his 50s finds that he does his best work when he allows himself to daydream or even take a break and play a video game. According to Erikson, this individual is high on the psychosocial quality of [BLANK-1].

All of the following examples are results due to primary aging EXCEPT:

Which research measure would be best suited for witnessing rare occurrences in everyday life and why?

If a researcher interviews a group of 20-year-olds, a group of 40-year-olds, and a group of 60-year-olds about their social roles,  this would be an example of a(n) [BLANK-1] research design.

Which of the following influences on development, in Bronfenbrenner’s model, would be considered to fall into the microsystem?

According to developmental psychologists, the most significant age period of development is:

A block attached to an ideal spring oscillates on a frictionless horizontal surface (simple harmonic motion). At what point(s) in the motion is the block’s kinetic energy maximized and at what point(s) is the spring potential energy maximized? Explain how energy is exchanged between kinetic and potential forms during one cycle, and describe qualitatively what would change if there were small non-conservative losses (e.g., light damping). Write the points where the kinetic energy is maximized below, and your explanation in your scratch paper, which will be submitted to Gradescope at the end of the exam. For full credit, your answers should match, and the explanation in the scratch paper should be sufficient. (10 points)
