please check my answer thanks so much
Which of the following best describes when extinction occurs
A When a CS is repeatedly prsented and periodically followed ba a US
B When a CS is repeatedly presented without the prsention of a US
C CS and US are presented together
D CS is repeatedly overshadowed
This question doesn'tmake sense to me
I have learend that Extinction is a process by which a particular behavior decreases or disappears
The correct answer to the question is B: When a CS (conditioned stimulus) is repeatedly presented without the presentation of a US (unconditioned stimulus).
Now, let me explain why this answer is correct and how you can arrive at this conclusion.
When we talk about extinction in the context of classical conditioning, we are referring to the process of weakening or eliminating a previously learned association between a conditioned stimulus (CS) and an unconditioned stimulus (US). Extinction occurs when the CS is repeatedly presented without the US.
To understand this, let's break down each option mentioned in the question:
A) When a CS is repeatedly presented and periodically followed by a US: This statement is not describing extinction because it is indicating that the CS is still being paired with a US, which would strengthen the association between them.
B) When a CS is repeatedly presented without the presentation of a US: This option accurately describes extinction as the CS is being presented alone without the US, leading to a weakening of the association.
C) CS and US are presented together: This statement is not referring to extinction because presenting the CS and US together actually strengthens the association between them.
D) CS is repeatedly overshadowed: This option does not describe extinction directly. Overshadowing occurs when a more salient stimulus (one that grabs more attention) is paired with the CS, resulting in a weaker conditioning of the CS. However, extinction is specifically about weakening or eliminating the association between the CS and US.
So, in summary, Option B is the correct answer as it accurately describes the process of extinction in classical conditioning.
