in your study, you chose whether participants actually became fluent in a second language as a confounding variable. why did you make this choice?

Answer

We chose to control for whether participants became fluent in a second language because it may have influenced their performance on the dependent variable, which was a memory task in the second language. By controlling for this variable, we could more accurately isolate the effect of the independent variable (the type of memory task) on the dependent variable (memory performance).
