Sleight of Hands

The task

This exercise consists of deciding whether a hand presented on the screen is a left or a right hand. To provide a varying degree of challenge, the hand can be presented under various conditions: just the hand itself, the hand in action with an object, or a mirror image of the hand.

What It Trains

Mental rotation is the main ability used in this exercise. This skill usually takes place in the right parietal region of the brain where perception occurs. Mental rotation comparison tasks can be broken down into five components: (1) create a mental representation of an object, (2) rotate the representation until a desired configuration is reached for comparison, (3) compare the rotated configuration , (4) decide if the representation and physical object are the same or not (5) report the decision and re perform these steps until correct solution is reached.
