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 ...
Weighted interval scheduling is a generalization where a value is assigned to each executed task and the goal is to maximize the total value. The solution need not be unique. The interval scheduling problem is 1-dimensional – only the time dimension is relevant. The Maximum disjoint set problem is a generalization to 2 or more dimensions ...
This is the same coupling coefficient as an FT schedule, except it is an exact solution for VT schedules rather than an approximation. Once again, the feedback function on these non-contingent schedules predicts serious instability in responding. As with FI schedules, variable-interval schedules are guaranteed a target response coupling of b.
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 ...
Interval schedule: based on the time intervals between reinforcements. [8] Fixed interval schedule (FI): A procedure in which reinforcements are presented at fixed time periods, provided that the appropriate response is made. This schedule yields a response rate that is low just after reinforcement and becomes rapid just before the next ...

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.
The matching law can be applied to situations involving a single response maintained by a single schedule of reinforcement if one assumes that alternative responses are always available to an organism, maintained by uncontrolled "extraneous" reinforcers. For example, an animal pressing a lever for food might pause for a drink of water.
