Attention and awareness in stage magic: turning tricks into research

Nature Reviews Neuroscience volume 9, pages 871–879 (2008)Cite this article

Abstract

Just as vision scientists study visual art and illusions to elucidate the workings of the visual system, so too can cognitive scientists study cognitive illusions to elucidate the underpinnings of cognition. Magic shows are a manifestation of accomplished magic performers' deep intuition for and understanding of human attention and awareness. By studying magicians and their techniques, neuroscientists can learn powerful methods to manipulate attention and awareness in the laboratory. Such methods could be exploited to directly study the behavioural and neural basis of consciousness itself, for instance through the use of brain imaging and other neural recording techniques.

Colour-Changing Card Trick

Glossary

After-discharge

A sensory neuron's response to the turning off of a stimulus.

Blindsight

A neurological condition in which a patient with damage in the primary visual cortex is unaware of visual events that occur in the corresponding portion of the visual field, despite exhibiting good performance on visual tasks conducted in that region.

Change blindness

The failure to notice changes in an object or scene over a period of time.

Inattentional blindness

The failure to notice a salient object or visible feature in a scene owing to misdirected attention or attention that is not engaged at a level sufficient to achieve awareness of the object.

Magic palming technique

The technique used by magicians to hide items in the palms of their hands (which are turned away from the observer), so as to make it look like the hands are empty.

Microsaccades

Small, involuntary saccades that are produced when subjects attempt to fixate their gaze on a visual target.

Saccade

A fast, jerky eye movement that transports the fovea from one visual target to another in a straight-line trajectory.

Smooth pursuit movement

A type of eye movement in which the retinal fovea smoothly tracks the position of a moving object.
