Quizplus · Accepted Answer

The experiment described is a correlational study, as it aims to examine the relationship between two variables (performance on a cognitive task and age) without manipulating either variable. There is no somatic or epigenetic intervention, as the study is only measuring existing variables. There is no behavioral intervention, as the study does not aim to change the behavior of the participants.
