Not All Same-Different Discriminations Are Created Equal: Evidence Contrary to a Unidimensional Account of Same-Different Learning

Peer reviewed

Gibson, Brett M.; Wasserman, Edward A.; Cook, Robert G. – Learning and Motivation, 2006

In Experiment 1, we trained four pigeons to concurrently discriminate displays of 16 same icons (16S) from displays of 16 different icons (16D) as well as between displays of same icons (16S) from displays that contained 15 same icons and one different icon (15S:1D). The birds rapidly learned to discriminate 16S vs. 16D displays, but they failed…

Natural Concepts in Pigeons

Peer reviewed

Herrnstein, R. J.; And Others – Journal of Experimental Psychology: Animal Behavior Processes, 1976

Pigeons learned discrimination rapidly and responded differentially to pictures seen for the first time. The essential feature of a natural discrimination--which is the ability to cope with natural ranges of variation--was approached and earlier experimental results were extended using other classes of stimuli.
