What will happen in a classical conditioning experiment if the likelihood of the US following the CS is 30% and the likelihood of the US being presented alone is also 30%?
A) There will be no conditioning, no matter how contiguous the CS and US.
B) There will be strong conditioning if the US arrives about half a second after the CS.
C) There will be no obvious effect at first, but after a rest period the CR will appear when the CS is presented.
D) The animal will show surprise reactions when the CS is presented.

In classical conditioning, the contingency between the CS and US is an important factor in determining the strength of conditioning. If the likelihood of the US following the CS is low (30% in this case), the CS will not be a reliable predictor of the US, and conditioning will not occur. Additionally, if the likelihood of the US being presented alone is also high (30%), the animal may not learn to associate the CS with the US, as it may not perceive the US as a consequence of the CS. Therefore, there will be no conditioning in this scenario, regardless of the temporal contiguity between the CS and US.
