Question 1

What happens during the acquisition phase of classical conditioning?

Accepted Answer

During acquisition, a neutral stimulus like a bell is repeatedly paired with an unconditioned stimulus such as meat powder until the bell alone triggers a conditioned response of salivation. This learning process relies on contiguity, requiring the bell and meat powder to be paired closely in time, and contingency, meaning the bell must consistently predict food arrival for a strong association to form.

Question 2

How do contiguity and contingency differ in classical conditioning?

Accepted Answer

Contiguity refers to the temporal closeness between the conditioned stimulus and unconditioned stimulus, requiring them to be paired within a fraction of a second. Contingency involves predictability—the conditioned stimulus must consistently signal the unconditioned stimulus. If the bell rings randomly without food, the dog fails to associate the bell with food, weakening the conditioned response regardless of timing.

Question 3

What is the difference between generalization and discrimination in classical conditioning?

Accepted Answer

Generalization occurs when stimuli similar to the conditioned stimulus trigger the conditioned response; a dog conditioned to a bell may also salivate to a whistle. Discrimination is the opposite—the dog learns to respond only to the specific conditioned stimulus when other similar stimuli are not paired with food. These processes demonstrate how animals refine their learned associations.

Question 4

What occurs during extinction in classical conditioning?

Accepted Answer

Extinction is the process where a conditioned response diminishes and disappears when the conditioned stimulus is repeatedly presented without the unconditioned stimulus. If the bell rings without food several times, the dog gradually stops salivating in response to the bell. This demonstrates that the learned association weakens when the predicted outcome no longer follows the stimulus.

Question 5

Can an extinguished conditioned response return after extinction?

Accepted Answer

Yes, spontaneous recovery can occur, where an extinguished conditioned response reappears after a period of rest. Days after extinction, the dog might briefly salivate again upon hearing the bell. This indicates that the learned association is not entirely erased but rather suppressed, and the memory can resurface under certain conditions.

Question 6

Why is the timing between stimuli important in classical conditioning?

Accepted Answer

Timing is critical because contiguity requires the conditioned stimulus and unconditioned stimulus to be paired closely in time, typically within a fraction of a second. If there is a significant delay between the bell and meat powder, the association weakens substantially. Effective classical conditioning depends on this temporal proximity for the animal to form a strong predictive link between the two stimuli.

Question 7

How does classical conditioning demonstrate associative learning?

Accepted Answer

Classical conditioning shows associative learning by transforming a neutral stimulus into a conditioned stimulus through repeated pairing with an unconditioned stimulus. The bell becomes associated with food, enabling it to elicit salivation independently. This foundational process reveals how organisms learn to predict events and adjust their behavior based on stimulus associations, forming the basis for understanding broader learning mechanisms.
