Different types of learning

Non-associative Learning

It is what we see when a sitimulus is presented repeatedly.

There is the Habituation and Sensitization

Habituation

This is when a stimulus is keep repeatedly to a organism and the organism will gradually change the magnitude.

Such as when we goes to a environment we will gradually notice less.

Sensitization

This is the opsitie as Habituation

Or in a quite room clock keep ticking it will become more annoying and noticeable.

What determines whether sensitization or habituation?

Both basic forms of non-associative learning happen when stimuli are repeated.

It depends on the overall level of repetition thats in your brain.

One theory is that both occur simultaneously and that the learning that manifests depends on the organism’s state of arousal

Can infants detect the difference between stimuli?

This is a application of how infants react to the world and learn the world.

Sometimes infants show us that they can tell two things apart by showing a preference for one thing over another.

For example, infants look longer at faces than some other patterns

But sometimes they don’t show a preference, and this could be for a couple of reasons:

  1. Maybe they can tell them apart but don’t prefer one to another
    1. Maybe they just can’t tell the difference.

We can use habituation to figure out whether infants can tell things apart

Classical Conditioning

Making connections between stimuli

Classical Conditioning: Pavlov’s dogs

If show dog a food, there will be a natural respond before learning

This is called a unconditional response, because it’s with out any training.

The other thing relevant here is this not connected element inside the dog. In this case it don’t provoke any response.

Then there is the Period of training, present a other stimulus with the unconditioned stimulus

Now just raining the bell is a conditioned stimulus - because now rining the bell will let the dog respond the bell.

The other example is this high schooler trying to condition his younger brother.

The Quack - Neutral stimulus

The Gun - Unconditioned Stimulus (US)

The Reaction - Unconditioned Response (UR)

After conditioning:

Conditioned Stimulus (CS)

Conditioned Response (CR)
