Animal procrastination: Pigeons choose to defer experiencing an aversive gap or a peck requirement.

abstract：:We frame behavior in classical conditioning experiments as the product of normative statistical inference. According to this theory, animals learn an internal model of their environment from experience. The basic building blocks of this internal model are latent causes-explanatory constructs inferred by the animal tha...
