Study procedure. After introducing the tasks, the electroencephalography (EEG) devices were worn. Participants first opened or closed their eyes for 2 min. Then, the five cognitive-factor induction tasks (each one tailored to remote association, common association, retrieval, combination, and recall) were conducted in random order. The entire study lasted around 1 h. Participants can have a 5-min rest after each induction task.
