The Premack Principle describes how activities can be used as reinforcers for behavior that is less probable in an individual. In this lesson.

In the second phase of the experiment, the children were tested with one of two procedures. Several subsequent experiments have supported this alternative to the Premack principle.
Stated objectively, if high-probability behaviors more desirable behaviors are made contingent upon lower-probability behaviors less desirable behaviorsthen the lower-probability rpincipio are more likely to occur.

This page was last edited on 22 Marchat David Premack and his colleagues, and others, have conducted a number of experiments to test the effectiveness of the Premack principle in humans.
The roles of responses were reversed in the second test, with corresponding results. Such observations led the team of Timberlake and Allison to propose the Response Deprivation hypothesis. The Premack principle was derived from a study of Cebus monkeys by Professor David Premackbut it has explanatory and predictive power when applied to humans, and it has been used by therapists practicing applied behavior analysis.
Premack’s principle – Wikipedia
Premack’s principle may be violated if premck situation or schedule of reinforcement provides much more of the high-probability behavior than of the low-probability behavior. All articles with unsourced premmack Articles with unsourced statements from March Premack’s principle suggests that if a person wants to perform a given activity, the person will perform a less desirable activity to get at the more desirable activity; that is, activities may themselves be reinforcers.
Some of the children preferred one activity, some the other.
The results were consistent with the Premack principle: Just as “reward” was commonly used to alter behavior long before “reinforcement” was studied experimentally, the Premack principle has long been informally understood and used in a wide variety of circumstances.
One of the earliest studies was conducted with young children.
Premack gave the children two response alternatives, eating candy or playing a pinball machine, fe determined which of these behaviors was more probable for each child. In effect, the subject must subsequently increase responding to make up for the “deprivation” of the contingent response. Premack’s principleor the relativity theory of reinforcementstates that more probable behaviors will reinforce less probable behaviors.
This study, among others, helps to confirm the Premack principle in showing that a high-probability activity can be an effective reinforcer for an activity that the subject is less likely to perform. Views Read Edit View history. From Wikipedia, the free encyclopedia.
That is, only children who preferred playing pinball over eating candy showed a reinforcement effect. An example is a mother who says “You have to finish your vegetables low frequency before you can eat any ice cream high frequency “.
Retrieved from ” https: More desirable behaviors are those that individuals spend more time doing prncipio permitted; premaxk desirable behaviors are those that individuals spend less time doing when free to act.
In one procedure, eating was the reinforcing response, and playing pinball served as the instrumental response; that is, the children had to play pinball in order to eat candy. Reinforcement occurs only when the situation is set up so that access to the contingent response has been reduced principii to its baseline level.
