BASIC REINFORCEMENT STRATEGY


The term reinforce means to strengthen, and is used in psychology to refer to anything stimulus which strengthens or increases the probability of a specific response. For example, if you want your dog to sit on command, you may give him a treat every time he sits for you. The dog will eventually come to understand that sitting when told to will result in a treat. This treat is reinforcing because he likes it and will result in him sitting when instructed to do so.
There are four types of reinforcement: positive, negative, punishment, and extinction. We’ll discuss each of these and give examples.

    Punishment:
    Punishment refers to adding something aversive in order to decrease a behavior. The most common example of this is disciplining (e.g. spanking) a child for misbehaving. The reason we do this is because the child begins to associate being punished with the negative behavior. The punishment is not liked and therefore to avoid it, he or she will stop behaving in that manner.

    Extinction:
    When you remove something in order to decrease a behavior, this is called extinction. You are taking something away so that a response is decreased.

    Positive Reinforcement:
    Positive re-enforcement is institution of reward for a particular desired behaviour. The intensity of reward must stimulate a desired behaviour. The examples above describe what is referred to as positive reinforcement. Think of it as adding something in order to increase a response. For example, adding a treat will increase the response of sitting; adding praise will increase the chances of your child cleaning his or her room. The most common types of positive reinforcement or praise and rewards, and most of us have experienced this as both the giver and receiver.

    Negative Reinforcement:
    In organizations acts are committed or omitted. For commission of desired acts a reward is given while rewards can also be given for displaying behaviour by terminating undesired consequences. Think of negative reinforcement as taking something negative away in order to increase a response. Imagine a teenager who is nagged by his mother to take out the garbage week after week. After complaining to his friends about the nagging, he finally one day performs the task and to his amazement, the nagging stops. The elimination of this negative stimulus is reinforcing and will likely increase the chances that he will take out the garbage next week.
