Allocation of complex, sequential operants on multiple and concurrent schedules of reinforcement.

abstract：:Responding under fixed-interval schedules usually generates either scalloped or break-and-run cumulative records. Earlier, it was generally accepted that the characteristic pattern was the scallop, but in recent years there has been an increasing emphasis on the break-and-run pattern. The break-and-run pattern has bee...
