fixed interval scallop: the pattern of responding that develops with fixed interval reinforcement schedule, performance on a fixed interval reflects subject's accuracy in telling time. Organisms whose schedules of reinforcement are "thinned" (that is, requiring more responses or a greater wait before reinforcement) may experience "ratio strain ...
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.
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.
In operant conditioning, the matching law is a quantitative relationship that holds between the relative rates of response and the relative rates of reinforcement in concurrent schedules of reinforcement. For example, if two response alternatives A and B are offered to an organism, the ratio of response rates to A and B equals the ratio of ...
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 ...
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 ...
Fixed interval The first response that is emitted after a set time has elapsed is reinforced. [11] While continuous reinforcement in a fixed ratio schedule may be necessary for the initial learning stages, a variable ratio schedule is the most effective at maintaining behavior over long periods of time. [12]
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]
