Might there be parallels between category learning in animals and word learning
in children? To examine this possibility, we devised a new associative learning
technique for teaching pigeons to sort 128 photographs of objects into 16 human
language categories. We found that pigeons learned all 16 categories in parallel,
they perceived the perceptual coherence of the different object categories, and
they generalized their categorization behavior to novel photographs from the
training categories. More detailed analyses of the factors that predict
trial-by-trial learning implicated a number of factors that may shape learning.
First, we found considerable trial-by-trial dependency of pigeons' categorization
responses, consistent with several recent studies that invoke this dependency to
claim that humans acquire words via symbolic or inferential mechanisms; this
finding suggests that such dependencies may also arise in associative systems.
Second, our trial-by-trial analyses divulged seemingly irrelevant aspects of the
categorization task, like the spatial location of the report responses, which
influenced learning. Third, those trial-by-trial analyses also supported the
possibility that learning may be determined both by strengthening correct
stimulus-response associations and by weakening incorrect stimulus-response
associations. The parallel between all these findings and important aspects of
human word learning suggests that associative learning mechanisms may play a much
stronger part in complex human behavior than is commonly believed.
