The Binding Problem(s) 8/25/2010 9:38 AM

The neural binding problem (NBP) encompasses three distinct situations: feature binding, variable binding, and the subjective unity of perception. Feature binding involves associating the correct (visual) features with objects and is fairly well understood. Variable binding arises in natural language and other abstract thought; there are ingenious proposed models, but no experimental confirmation. The subjective unity of perception is the deepest variant of the NBP, but unfortunately, contemporary science has nothing to say about it.
