Answer:
D. Crossword Puzzle Performance
Explanation:
In experiments, we have the Independent and Dependent variables. The dependent variable is the variable being measured while the independent variable influences the dependent variable and can be manipulated by the exprimenter. In the scenario above, the Independent variable is the stress task vs. no stress task which is manipulated by the researcher as he has the power to assign the participants to either groups.
The effect of the stress task would influence the performance of the participants at the crossword puzzle which is a measure of cognition. Therefore, the later becomes the dependent variable in the research because the cognition ability reflected in the crossword puzzle performance is the variable being measured.
