What is extinction and when does it occur?
Extinction occurs when species are diminished because of environmental forces (habitat fragmentation, global change, natural disaster, overexploitation of species for human use) or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers).
How does extinction occur in classical conditioning quizlet?
In classical conditioning, extinction occurs when the conditioned stimulus is presented several times after the unconditioned stimulus has been withdrawn. the name given to the conditioned stimulus before it becomes conditioned. It is referred to as a neutral stimulus while it fails to produce a response.
What is extinction in psychology quizlet?
extinction. the diminishing of a conditioned response; occurs in classical conditioning when an unconditioned stimulus (US) does not follow a conditioned stimulus (CS); occurs in operant conditioning when a response is no longer reinforced. ( Myers Psychology 8e p.
What causes extinction quizlet psychology?
What is extinction during classical conditioning? Caused when no reinforcement is given after operant response.
What are the 4 main causes of extinction?
Overview. There are five major causes of extinction: habitat loss, an introduced species, pollution, population growth, and overconsumption. Through the activity, students will create a list of reasons why animals can become extinct.
What are examples of extinction?
In psychology, extinction refers to the gradual weakening of a conditioned response that results in the behavior decreasing or disappearing. In other words, the conditioned behavior eventually stops. For example, imagine that you taught your dog to shake hands. Over time, the trick became less interesting.
How extinction occurs in classical conditioning?
In classical conditioning, extinction occurs when the conditioned stimulus is applied repeatedly without being paired with the unconditioned stimulus. Over time, the learned behavior occurs less often and eventually stops altogether, and conditioned stimulus returns to neural.
Whose behavior is most likely to show the greatest resistance to extinction?
The behavior that is most likely to show the greatest resistance to extinction is Rick, in which he sometimes gets what he asks from his parents when they are shopping. The greatest resistance to extinction occurs when there is an occurrence of partial reinforcement schedules in which is seen in the behavior of Rick.
What will happen if a conditioned stimulus is repeatedly?
If the conditioned stimulus is repeatedly presented without the unconditioned stimulus, the conditioned response will eventually be eliminated. The idea that the conditioned response will be made to stimuli that are similar to the conditioned stimulus.
What are three main effects of extinction psychology?
2) The three main effects of extinction is that the rate of responding decreases, the response variability increases, and there is an increase in emotions (frustration).
What causes extinction?
Extinction happens when environmental factors or evolutionary problems cause a species to die out. Humans also cause other species to become extinct by hunting, overharvesting, introducing invasive species to the wild, polluting, and changing wetlands and forests to croplands and urban areas.
What is meant by extinction and spontaneous recovery?
Spontaneous recovery can be defined as the reappearance of the conditioned response after a rest period or period of lessened response. If the conditioned stimulus and unconditioned stimulus are no longer associated, extinction will occur very rapidly after a spontaneous recovery.
What is the difference between generalization and discrimination?
Here’s how they work. Psychology’s definition of discrimination is when the same organism responds differently to different stimuli. This means that you discriminate in your reactions to the two different animals. In generalization, on the other hand, the organism has the same reaction to different stimuli.
What consequence is most conducive to learning?
According to Skinner, what consequence is most conducive to learning? Positive reinforcement and positive punishment are similar in that both: a. Produce an decrease in the probability of a behavior.
What is meant by extinction of a conditioned response quizlet?
Extinction (in Classical Conditioning) Reduction of a learned response that occurs because the conditioned stimulus is no longer paired with the unconditioned stimulus. Also, the procedure of repeatedly presenting a conditioned stimulus without the unconditioned stimulus.
