Some people may use an intermittent reinforcement schedule that include: fixed ratio, variable ratio, fixed interval and variable interval. Another option is to use a continuous reinforcement. Schedules can be both fixed and variable and also the number of reinforcements given during each interval can vary. [10]
Administrating two reinforcement schedules at the same time Concurrent schedules – A complex reinforcement procedure in which the participant can choose any one of two or more simple reinforcement schedules that are available simultaneously. Organisms are free to change back and forth between the response alternatives at any time.
The most notable schedules of reinforcement studied by Skinner were continuous, interval (fixed or variable), and ratio (fixed or variable). All are methods used in operant conditioning. Continuous reinforcement (CRF): each time a specific action is performed the subject receives a reinforcement. This method is effective when teaching a new ...
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.
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.
If R 1 and R 2 are the rate of responses on two schedules that yield obtained (as distinct from programmed) rates of reinforcement Rf 1 and Rf 2, the strict matching law holds that the relative response rate R 1 / (R 1 + R 2) matches, that is, equals, the relative reinforcement rate Rf 1 / (Rf 1 + Rf 2).
Shaping is a conditioning paradigm used primarily in the experimental analysis of behavior.The method used is differential reinforcement of successive approximations.It was introduced by B. F. Skinner [1] with pigeons and extended to dogs, dolphins, humans and other species.
The reinforcement schedule can also be manipulated to determine how motivated an animal is to receive stimulation, reflected by how hard they are willing to work to earn it. This can be done by increasing the number of responses required to receive a reward (FR-2, FR-3, FR-4, etc.) or by implementing a progressive-ratio schedule, where the ...
