Functions of the schedule of reinforcement
Simple schedules[ edit ] A chart demonstrating the different response rate of the four simple schedules of reinforcement, each hatch mark designates a reinforcer being given Ratio schedule — the reinforcement depends only on the number of responses the organism has performed.
Fixed time FT — Provides a reinforcing stimulus at a fixed time since the last reinforcement delivery, regardless of whether the subject has responded or not. This produces behavior similar to that seen during extinction.
Variable ratio schedule VR — reinforced on average every nth response, but not always on the nth response. Superimposed schedules[ edit ] The psychology term superimposed schedules of reinforcement refers to a structure of rewards where two or more simple schedules of reinforcement operate simultaneously.

Simple schedules[ edit ] A chart demonstrating the different response rate of the four simple schedules of reinforcement, each hatch mark designates a reinforcer being given Ratio schedule — the reinforcement depends only on the number of responses the organism has performed. As with primary reinforcers, an organism can experience satiation and deprivation with secondary reinforcers. An example would be reinforcing clapping to reduce nose picking Differential reinforcement of low response rate DRL — Used to encourage low rates of responding. These equations predicted, among other things, a violation of the constant-ratio rule of formal choice theory and an absence of simultaneous contrast effects between response alternatives reinforced on variable-interval schedules. In other words, it is a non-contingent schedule. The particular pattern of reinforcement has an impact on the pattern of responding by the animal. For example, anti-drug agencies previously used posters with images of drug paraphernalia as an attempt to show the dangers of drug use. The orderliness and predictability of behavior under schedules of reinforcement was evidence for B. The choice axiom after twenty years. Partial reinforcement schedules are more resistant to extinction than continuous reinforcement schedules. Example: FR4 when given a whistle and FI6 when given a bell ring. Reinforcement occurred after an average of 3 pulls on the lever. Clients: to guide your clients for the achievement of the goals or targets.
Informal persuasion This tells about the way in which a person interacts with colleagues and customers. Formal persuasion This type of persuasion is used in writing customer letter, proposal and also for formal presentation to any customer or colleagues.
Example: VR 10, after it is completed the schedule is changed without warning to FR 10, after that it is changed without warning to FR 16, etc. The orderliness and predictability of behavior under schedules of reinforcement was evidence for B.

Other definitions have been proposed, such as F. The correlation-based law of effect. Individual behaviors tend to generate response rates that differ based upon how the reinforcement schedule is created. Real-world example: changing channels on a television. For example, if the rabbit is reinforced every time it pulls the lever exactly five times, it would be reinforced on an FR 5 schedule. Partial reinforcement schedules are more resistant to extinction than continuous reinforcement schedules. Variable ratio schedule VR — reinforced on average every nth response, but not always on the nth response. Thus, one person may prefer one type of food while another avoids it. However, behavior reinforced under a partial schedule is more resistant to extinction. Fixed interval FI — reinforced after n amount of time. Later, when the behavior is well established, the trainer can switch to a partial or intermittent schedule. Concurrent schedules[ edit ] In operant conditioning , concurrent schedules of reinforcement are schedules of reinforcement that are simultaneously available to an animal subject or human participant, so that the subject or participant can respond on either schedule. Differential reinforcement of other behavior DRO — Also known as omission training procedures, an instrumental conditioning procedure in which a positive reinforcer is periodically delivered only if the participant does something other than the target response.
He did not use it, as it is today, for selecting and strengthening new behaviors. Much subsequent research in many labs examined the effects on behaviors of scheduling reinforcers.
In negative reinforcement, the stimulus removed following a response is an aversive stimulus; if this stimulus were presented contingent on a response, it may also function as a positive punisher.
If the average was about every 3 pulls, this would be a VR 3 schedule.
