It is widely acknowledged in neuroscience and psychology research that problem-solving abilities rely not only on language-analytical reasoning but also on temporal-spatial skills that we use to visualize some problems. 

Mental rotation, the main ability used in this exercise, usually takes place in the right cerebral hemisphere of the brain, more specifically, in the parietal regions where perception also occurs. Mental rotation comparison tasks can be analyzed into five steps: (1) create a mental image of an object, (2) rotate the object mentally until a comparison can be made, (3) make the comparison, (4) decide if the objects are the same or not and (5) report the decision.

Spatial reasoning is an important ability that we use on a daily basis. We use spatial reasoning skills to navigate through streets or explain where the placement of items should be. The skills used in Sleight of Hands may also help to improve tasks that require an individual to be able to differentiate between their left and right hands, such as shaking hands, typing, and playing video games.

You can modify:

• The number of hands (2, 4, 6, 8, 10, 15 or 20)
• The type of hands (alone, in action, or both types)
• Then hand presentation (normal, mirrored, or both presentations)
• The display time (unlimited, 10, 5, or 2 seconds)
• The time limit (unlimited, 10, 5, or 2 seconds)
