A researcher investigated the relationship between alcohol intake and reaction time using a driving simulation task. Participants drank either one or three ounces of pure alcohol with the taste masked by diluting the alcohol in a strong-tasting fruit punch. Their reaction time was measured in terms of the speed with which they braked on seeing a red light during the simulated driving task. In this case, the dependent variable in the experiment is the _____.

In this case, the dependent variable in the experiment is the reaction time shown by participants after drinking alcohol, as explained below.

What is a dependent variable?

When we conduct a experiment such as the one described in the question, the dependent variable is what we measure in the study, that is, the behavior that changes or is affected by the independent variable.

In this study, the independent variable is alcohol consumption. What is being measured after participants drink alcohol is their reaction time upon seeing a red light. Therefore, we can say that the dependent variable is the reaction time.
