A Researcher Performs a Cross-Sectional Study Comparing the Video Game

question 14

Multiple Choice

A researcher performs a cross-sectional study comparing the video game playing ability of 20-year-olds to 60-year-olds. The results indicate that the 20-year-olds learned to play a new game much faster than the 60-year-olds, however the researchers are uncertain whether this indicates that the 20-year-olds' ability will decrease over time, or whether the 60-year-olds had more difficulty because they grew up before there were video games. What issue is this an example of?

• A) cohort effects
• B) attrition
• C) sampling bias
• D) scaffolding effects
