concurrent schedule of reinforcement
the simultaneous presentation of two or more independent schedules, each leading to a reinforcer
Matching law
the proportion of responses emitted on a particular schedule matches the proportion of reinforcers obtained on that schedule
the proportion of responses is less different than expected. Occurs when there is little cost for switching between schedules
changeover delay
the cost of switching between schedules
the proportion of responses is more different than expected. Occurs when there is a high cost for switching between schedules.
Bias from matching
One response alternatives attracts a higher proportion of responses than expected, regardless of which is the richer and which is poorer.
Controlling response
Physical restraint, depriving and satiating, doing something else, self-reinforcement and self-punishment
Commitment response
an action carried out at an early point in time that serves either to eliminate or greatly reduce the value of an upcoming temptation
small-but-cumulative effects model
each individual choice on a self-control task has only a small but cumulative effect on our likelihood of obtaining the desired long-term outcome
