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

This is an example of cohort effects, which refer to differences in experiences or exposures between different generations that can affect study outcomes. The 20-year-olds and 60-year-olds likely had different levels of exposure to video games growing up, which could explain the difference in performance. However, this cannot be confirmed without further investigation into their video game exposure history.
