Abstract
Three pigeons with long operant conditioning histories were studied under a variable interval schedule as deprivation was varied. Periods of food deprivation up to 72 h and prefeeding up to 20 g of food had little effect upon responding. One pigeon did show a significant decrease in responding following a 10% increase in body weight. These findings indicate that variable interval responding in pigeons can become relatively insensitive to changes in deprivation.
