What does a pigeon see in a picasso?
Journal of the Experimental Analysis of Behavior,
69, 223-226.
The present paper is primarily a response to Watanabe, Sakamoto,
and Wakita's 1995 paper "Pigeons' Discrimination of
Paintings by Monet and Picasso." Our main criticism is that
the key term concept, and in particular the way in which a
class of stimuli is specified, remains equivocal. We argue that
it is only useful to study categorization if the organism in
question can be expected to have access to the information that
is used in defining the classes, and that evidence for
categorization requires selective responses that cannot be
attributed to similarity in features that are not essential to
the classification.
Key words: concept, stimulus control, pigeon
