Abstract
E. A. Wasserman, K. Kirkpatrick-Steger, L. J. Van Hamme, and
I. Biederman (1993)
demonstrated that scrambling an object's parts or "geons"
(
I. Biederman, 1987
) produced
marked reductions in the pigeon's picture recognition accuracy, indicating that discriminative responding to pictures is controlled
by more than simple particulate features. The present effort was
designed to further assess the contribution of various stimulus
attributes to picture perception. Four pigeons were trained to
discriminate 4 line drawings of human-made objects. Subsequent tests
revealed that (a) the spatial organization of the geons was a major
contributor to picture recognition; (b) the individual geons were
also important, with different pigeons demonstrating control by
different subsets of geons; (c) recognition of the training drawings
was positionally invariant; and (d) the points where the geons
contacted one another were largely unimportant for picture
recognition. The results provide further support for the notion that
pigeons perceive both global and local aspects of complex stimuli in
much the same way as do humans.
