What are some basic forms of learning?
We Learn by Association
This process is called conditioning
There are two forms of conditioning:
1. Classical (Involuntary Behaviors)

Pavlov’ Study: Terminology
Neutral Stimulus (NS)- in classical conditioning, a stimulus that elicits no response before conditioning.
Unconditioned stimulus (UCS) - a naturally occurring stimulus that leads to an involuntary response.
Unconditioned means “unlearned” or “naturally occurring.”
Unconditioned response (UCR) - an involuntary response to a naturally occurring or unconditioned stimulus.
Conditioned stimulus (CS) - stimulus that becomes able to produce a learned reflex response by being paired with the original unconditioned stimulus.
A neutral stimulus can become a conditioned stimulus when paired with an unconditioned stimulus.
Conditioned response (CR) - learned reflex response to a conditioned stimulus.Sometimes called a conditioned reflex.

CLASSICAL CONDITIONING BASICS
• Classical Conditioning (involuntary responses)• Acquisition
– The initial stage in classical conditioning in which an association between a neutral stimulus and an unconditioned stimulus takes place
– In this process the conditioned stimulus needs to come before the unconditioned stimulus
– The time between the two stimuli should only be half a second

Higher Order Conditioning
• AKA- Second Order Conditioning: After a Conditioned Stimulus (CS1) has been established, another conditioned stimulus (CS2) can be added to induce the Conditioned Response (CR).
16
Example: Once the dog has been conditioned to drool to the sound of the bell, the dog can be conditioned again to drool to the sight of a ball using only the bell and no food.
First-Order and Second-Order ConditioningFirst Order Conditioning.
•Bell + meat = salivation. •Bell = Salivation.
Second Order Conditioning(After first order conditioning has occurred)
•Light + Bell = Salivation.
•Light = Salivation.

Classical Conditioning
• Extinction (Extinguished)– A stoppage of the conditioned response– May be learned or occur naturally
• Spontaneous Recovery– After a resting period, sometimes the classically
conditioned behavior reappears. “Old feelings” come back for no reason

• Discrimination– The learned ability to
distinguish between two stimuli that are similar

– Sometimes called the contingency model of classical conditioning
– showed that animals will learn better through classical conditioning if the UCS reliably predicts the CS
– Point to remember: cognition also plays a role in classical conditioning

Biological Predispositions•The Garcia Effect
– Sometimes referred to as Taste Aversion
– Garcia showed that the duration between the CS and the US may be long (hours), but yet result in conditioning.
– A biologically adaptive CS (taste) led to conditioning and not to others (light or sound).
– Used by ranchers in California to prevent wolves from eating sheep

Token Economy
• Every time a desired behavior is performed, a token is given.
• They can trade tokens in for a variety of prizes (reinforcers)
• Used in homes, prisons, mental institutions and schools.
Premack Principle
• You have to take into consideration the reinforcers used.
• Is the reinforcer wanted….or at least is it more preferable than the targeted behavior.
Red Robin’s Whiskey River Veggie burger might be a great positive reinforcer for me, but it would not work well on a carnivore.

you study. Your parent’s goal: to get you to increase your performance and study time.
• Punishment– Used to DECREASE a behavior from reoccurring.– Example: You do poorly on your psychology test, so your parents take
away your cell phone. Your parent’s goal: to stop you from doing other things that distract you and lead to performing poorly on tests in the future.
