Je. Hummel et Pj. Kellman, FINDING THE POPE IN THE PIZZA - ABSTRACT INVARIANTS AND COGNITIVE CONSTRAINTS ON PERCEPTUAL-LEARNING, Behavioral and brain sciences, 21(1), 1998, pp. 30
Schyns, Goldstone & Thibaut argue that categorization experience resul
ts in the learning of new perceptual features that are not derivable f
rom the learner's existing feature set. We explore the meaning and imp
lications of this ''nonderivability'' claim and relate it to the quest
ion of whether perceptual invariants are learnable, and if so, what mi
ght be entailed in learning them.
