Abstract
Four pigeons responded under chained variable-interval schedules in which the required response topographies were either similar (i.e., a homogeneous chain) or dissimilar (i.e., a heterogeneous chain). The pigeons were exposed to all possible combinations of initial-link key pecking or treadle pressing and terminal-link pecking or treadling. Three of four birds displayed higher initial-link response rates under the homogeneous chains. These results were explained in terms of an induction effect in which the strengthening effect of reinforcing a particular terminal-link response topography generalizes to similar responses earlier in the chain but not to topographically different responses.
