A researcher performs a 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)stage model error
D)experimenter expectancy effects

This is an example of cohort effects, as the differences in video game ability could be due to the fact that the 60-year-olds grew up before video games were invented and thus did not have as much exposure or experience with them.
