binding problem

Syllable breakdown

Dictionary meaning

The question of how the brain integrates separate, spatially distributed representations of different features (colour, shape, motion, sound) of a perceived object into a single, unified conscious experience; a central puzzle in neuroscience and philosophy of perception

History and origin

Described as the 'binding problem' since the 1980s; connected to the classical philosophical problem of the unity of consciousness; gamma-band neural synchrony was an early proposed solution

Examples

• The binding problem asks how you experience a red bouncing ball as a unified percept rather than separate patches of colour, motion, and shape.
• Feature integration theory by Anne Treisman was an influential early attempt to address the binding problem.

Synonyms: combination problem, unity of consciousness problem
