Brain-training apps are
                popular. But can they help
                you succeed in college?

                                           processing speeds, better memory, and problem solving (Hardy
                                           et al., 2015). That sounds promising, but a brain-training company
                                           funded the study and also happened to employ the study’s authors.
                                           However, another study found that training memory had benefits,
                                           but mainly for subsequent tasks that were more similar to the training
                                           (Gathercole et al., 2019). Now you aren’t sure what to think. To really
                                           be convinced, you need to answer a key question: Does brain-training
                                           improve college performance?


                                           Where Do the Data come From?
                                                   According to a social butterfly friend of yours, he has 12
                                                   friends who are using brain-training and 13 who aren’t, and
                                                   you’re curious to know if you could actually see any differ-
                                           ences between the two sets of people.
                                             To see brain-training’s potential for improving college performance,
                                           the exercises would need to improve outcomes on a task that col-
                                           lege students typically have to do. College students’ most common
                                           course-related task is still studying notes and taking a test on that
                                           material. You ask your friend if his acquaintances are up for a little
                                           challenge. You take a section of notes from your first-year history
                                           course, and the 10-question multiple-choice weekly quiz that went
                                           with it. You give your participants 15 minutes to study the notes, then
                                           they take the quiz. You note their scores along with whether they had
                                           been doing brain-training (see Figure 10.1).
