Final answer:
Extinction in psychology involves the decline of learned behaviors due to lack of reinforcement. This process leads to behaviors being 'extinguished,' and can be observed in various conditioning types.
Explanation:
Extinction refers to the decrease in the strength of a learned behavior when the conditioned stimulus is presented without the unconditioned stimulus or when the behavior is no longer reinforced. It describes both the procedure and the result where the learned response declines.
Behaviors reduced through extinction are considered 'extinguished.' This process can be seen in various conditioning types such as classical and instrumental conditioning, where behaviors cease due to the lack of reinforcement.
A concrete example of extinction is when parents stop rewarding a child's tantrums with attention, leading to the eventual cessation of tantrum throwing behavior.
