What is overshadowing in classical conditioning?
n. in classical conditioning, a decrease in conditioning with one conditioned stimulus because of the presence of another conditioned stimulus. Usually a stronger stimulus will overshadow a weaker stimulus.
What does the blocking effect demonstrate?
Kamin’s Blocking effect demonstrates that conditioning to a stimulus could be blocked if the stimulus were reinforced in compound with a previously conditioned stimulus. For example, an animal is exposed to conditioned stimulus 1 (CS1), which predicts the occurrence of a reinforcer.
What is blocked during blocking psychology?
In psychology, the term blocking refers broadly to failures to express knowledge or skill because of failures of learning or memory, as in the everyday experience of “blocking” of the name of a familiar face or object.
What is high latent inhibition?
The latent inhibition paradigm assesses a subject’s tendency to ignore irrelevant stimuli, a process integral to healthy perceptual and cognitive function that has been hypothesized to be a key deficit underlying the development of schizophrenia.
What’s the definition of overshadowing?
1 : to cast a shadow over. 2 : to exceed in importance : outweigh. Synonyms & Antonyms Example Sentences Learn More About overshadow.
What is blocking in psychology learning?
Blocking refers to the finding that less is learned about the relationship between a stimulus and an outcome if pairings are conducted in the presence of a second stimulus that has previously been established as a reliable predictor of that outcome.
What is an example of overshadowing in psychology?
Overshadowing is when the first stimulus has no more stimulus control. An example is a teenager who can study in a classroom, but not in front of the a group of cheerleaders.
What disorder does Michael Scofield have?
Michael has been clinically diagnosed with low latent inhibition, a condition in which his brain is more open to incoming stimuli in the surrounding environment. As a result of this condition, he is unable to block out periphery information and instead processes every aspect and detail of any given stimulus.
Is low latent inhibition good?
But it turns out there’s a good side to low latent inhibition, too. In people with high intelligence and good working memory (an ability to think about many things at once), it can lead to original ideas and creative achievement.
What does block out mean?

Does latlatent inhibition exist in schizophrenics?
Latent inhibition (attenuated responding to a signal due to signal-alone presentations preceding the signal-outcome pairings) and blocking (attenuated responding to Signal B due to Signal A being paired with the outcome prior to pairings of an AB compound with the outcome) are reportedly absent in acute schizophrenics.
How does context exposure affect overshadowing and blocking?
The present experiments delineate the effects of context exposure on reducedOV and blocking. Experiment 1a indicates that overshadowing is greatly reduced when the overshadowing stimulus is preexposed in a relatively short training session, and it is less affected when the training session is longer.
Is overshadowing a useful procedure to Prese NT et al?
However, overshadowing remains of interest in its own right as a procedure to prese nt et al. 2011 ). error. Through unblocking manipulations, we can s tudy the liberation of attention by surprise and drug effects thereon. However, the reliable dem onstration of unblocking can require ex tensive behavioral pilot work.
What is the difference between overshadowing and reducedov?
Thus, the ECH posits that overshadowing occurs because X impairs responding to Z at test, and reducedOV occurs because the context interferes with X’s ability to serve as an effective comparator stimulus. This differs from the SOP account because the formation of the Z-O association is unaffected according to the ECH.
