Mind’s Eye uses a technique known as sensory discrimination. Sensory discrimination tasks require the brain to focus on one particular aspect of the visual field while ignoring similar visual distractors. In Mind’s Eye, the task is asked to remember a target image and determine whether a set of similar images presented contain the target image.
Here’s how the exercise works: A moving image will be shown. Remember the direction in which the image is moving for the duration of the exercise. The particular pattern within the moving image isn’t important - the direction in which the image is moving is what is important.
The exercise will then display three moving images in succession. The challenge is to identify if any of the three images were moving in the same direction as the original moving image. All three images must play before an answer can be given. If none of the images match the original image, then select “not presented”.
Once a selection is made, another three moving images will appear and the process repeats.
(Tip!: If you forget what direction the image seems to be moving in, you can press the pause button to pause the exercise. When you unpause the exercise, you will be shown a new moving image, giving you a new target.)
