ABSTRACT
As organisms learn to predict and control their environment through serial observation, they have to assess the correlations that exist between important stimulus events. What signals accompany danger and safety? What behaviours are forbidden or allowed? Which traits characterize which social group? Or more generally, which causes precede which effects or consequences? The ability to figure out the correlations that hold between signals and their meanings, behaviours and reinforcements, groups and social attributes, or causes and effects, is a basic module of adaptive intelligence.
