Pigeons either trained to treadle hop for food or given response-independent food were exposed to positive and negative keypeck automaintenance procedures. Effects of pretraining on acquisition of keypecking were minimal. Measures of asymptotic levels of pecking indicated that treadle-trained pigeons with access to the treadle during automaintenance and pigeons that had obtained free food pecked less than either naive pigeons or treadle-trained pigeons that did not have access to the treadle during automaintenance. On negative automaintenance, treadle-trained pigeons pecked substantially more than either naive or free-food pigeons. These data suggest that prior experience influences automaintenance via response competition, rather than by inducing states of learned laziness or industriousness in organisms, as suggested by Engberg, Welker, Hansen, and Thomas (1973).
