An operant response is a behavior that is modifiable by its consequences. When behavior is modified by its consequences, the probability of that behavior occurring again may either increase (in the case of reinforcement) or decrease (in the case of punishment). Show For example, speeding through a red light may lead to getting struck broadside by another vehicle. If this consequence follows such a response, then the likelihood of a person's responding in the same way under similar conditions should drop significantly. It is also possible for temporal or topographical properties of behavior to be modified by reinforcement (in the case of response differentiation). Quotations Free Operant Once an operant response occurs, it may be "free" or available to occur again without obstacle or delay. This would be the case, for example, of someone picking up a stone from a rocky beach and skipping it across the water. Other operants are only available for very limited periods of time and cannot be freely repeated. This would be the case, for example, of someone wishing their friend a happy birthday. Operant Level Operant behaviors occur at some base rate prior to reinforcement. This unconditioned level of responding is called the operant level. The operant level is one of a number of ways (like the yoked control) in which we can determine whether or not changes in the occurrence of the operant response are due to the prevailing contingencies of reinforcement. Glossary Index
What has occurred when there is a decrease in the likelihood or rate of a target response?Punishment occurs when a stimulus delivered to an organism decreases the rate, or probability, of a response that preceded it.
What decreases the likelihood a behavior will occur again?Punishment. As a reminder, punishment is a consequence that immediately follows a behavior and decreases the future likelihood of the behavior. As with reinforcement, there are two types of punishment: positive and negative.
What is the decrease in the conditioned response?Extinction is the decrease in the conditioned response when the unconditioned stimulus is no longer presented with the conditioned stimulus.
Which of the following decreases the likelihood that a response will recur?The correct answer is: c) positive punishment. Positive punishment is used to decrease an undesired response by adding something undesirable to their life. The answer is not b) response cost or d) negative punishment because response cost is a type of negative punishment.
