| Abstract: | We conducted four experiments in order to investigate whether pigeons' responses to a recently attended (i.e., recently pecked)
location are inhibited. In Experiments 1 and 2, stimulus displays were similar to those used in studies of inhibition of return
(IOR) with humans; responses to cued targets tended to be facilitated rather than inhibited. In Experiments 3 and 4, birds
were presented with stimulus displays that mimicked clusters of small grains and were relatively localized, which should have
been more appropriate for detecting IOR in pigeons. The results from these experiments again provided evidence for facilitation
of responding to cued targets, rather than for IOR. |
