This is called an "interval schedule". In addition, ratio schedules can deliver reinforcement following fixed or variable number of behaviors by the individual organism. Likewise, interval schedules can deliver reinforcement following fixed or variable intervals of time following a single response by the organism.
Fixed interval schedule: Reinforcement occurs following the first response after a fixed time has elapsed after the previous reinforcement. This schedule yields a "break-run" pattern of response; that is, after training on this schedule, the organism typically pauses after reinforcement, and then begins to respond rapidly as the time for the ...
This equation predicts serious instability for non-contingent schedules of reinforcement. Fixed-interval schedules are guaranteed a strengthening of a target response, b=w1, as reinforcement is contingent on this final, contiguous response (Killeen, 1994). This coupling is equivalent to the coupling on FR 1 schedules w1=b=1-e-l.
This schedule yields a response rate that is low just after reinforcement and becomes rapid just before the next reinforcement is scheduled. Variable interval schedule (VI): A procedure in which behavior is reinforced after scheduled but unpredictable time durations following the previous reinforcement. This schedule yields the most stable rate ...
He initially used the model to account for a pattern of behavior seen in animals that are being reinforced at fixed-intervals, for example every 2 minutes. [ 3 ] An animal that is well trained on such a fixed-interval schedule pauses after each reinforcement and then suddenly starts responding about two-thirds of the way through the new interval.
A s he prepares for his second term as President, Donald Trump’s approach on some issues is poised to mirror that of his first term. He's set to once again increase tariffs on imported goods and ...
For instance, Nevin, Tota, Torquato, and Shull (1990) had pigeons pecking lighted disks on separate variable-interval 60-s schedules of intermittent food reinforcement across two components of a multiple schedule. Additional free reinforcers were presented every 15 or 30 s on average when the disk was red, but not when the disk was green.
Can we imagine ourselves back on that awful day in the summer of 2010, in the hot firefight that went on for nine hours? Men frenzied with exhaustion and reckless exuberance, eyes and throats burning from dust and smoke, in a battle that erupted after Taliban insurgents castrated a young boy in the village, knowing his family would summon nearby Marines for help and the Marines would come ...
