An example of a slide from the Effectivate serious game for cognitive training in aging—the exercise, The Last One Counts, is based on the ‘n-back’ task. In this exercise, the users were presented with a sequence of shapes and asked to decide whether each shape is identical to the one previously presented. Task difficulty changed gradually by updating different parameters, such as exposure latencies. In advanced levels, users were asked to decide whether the current shape is the same as, different from, or partially similar to the previously presented one. This additional level of complexity requires users to segregate the item’s different features (ie, color and shape) to selectively focus on some and inhibit others.
