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.
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.
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.

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.
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]
The center itself—an open, free-flowing physical space on campus—was conceived of as the "chamber" in which instruction and learning occurred. The environment adhered in obvious ways to such cornerstone concepts as immediate positive reinforcement, successive approximation, schedules of reinforcement, discriminative stimuli and the like.
