Observational learning; bobo doll experiment
US (Unconditioned Stimulus)
A stimulus that naturally and automatically triggers a response (food)
UR (Unconditioned response)
The unlearned, naturally occurring response to the unconditioned stimulus (salivation)
CS (Conditioned stimulus)
An originally neutral stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response (a bell)
CR (Conditioned response)
The learned response to a previously neutral (but now conditioned) stimulus (salivation in response to the bell) Also called a learned response.
Progression of classical conditioning
US triggers a UR (all natural). A CS is associated with the US, both triggering a UR. The US is removed and the CS is used to triggered the UR (now a CR). When the CS triggers the UR the UR is now called a CR.
How is a learned response acquired in classical conditioning?
Its acquired through repeated pairings of the CS (neutral stimulus) with the US (unconditioned stimulus)
How is a learned response acquired in operant conditioning.
Its acquired through reinforcement or punishment, which strengthens or weakens the likelihood of a behavior occurring again.
When does extinction occur in classical conditioning?
Extinction occurs when the CS is repeatedly presented without the US, leading to a weakening and disappearance of the CR.
When does extinction occur in operant conditioning?
Extinction occurs when a behavior is no longer reinforced, leading to a decrease in its frequency.
Spontaneous Recovery
The reappearance, after a pause, of an extinguished conditioned response
Higher-order conditioning
A procedure in which the conditioned stimulus in one conditioning experience is paired with a new neutral stimulus, creating a second (often weaker) conditioned stimulus.
Stimulus Generalization
The tendency, once a response has been conditioned, for similar stimuli to illicit the same conditioned response. (dog responding to sit, but also hit and pit)
Stimulus Discrimination
The learned ability to distinguish between conditioned stimulus and similar stimulus and only respond with the CR to the CS. (dog responding to sit, but not hit, or pit)
The Little Albert Study
A controversial experiment by John B Watson demonstrating classical conditioning in humans. Little Albert (a baby) was conditioned to fear a white rat and other animals by pairing the white rat with a loud noise. (The fate of little albert is unknown)
Skinner Box
A chamber containing a bar or key that an animal can manipulate to obtain a food or water reinforcer; attached devices record the animals rate of bar pressing or key pecking.
Cumulative Record
A graphical record of responding and reinforcement in a skinner box as a function of time.
Reinforcement
Any event that strengthens the behavior it follows.
Punishment
Any event that weakens the behavior it follows
Primary Reinforcers
Natural, innate reinforcing stimuli, such as those that satisfy biological needs (Food, water, ect)
Secondary reinforcers
Stimula that gain their reinforcing ability through their association with primary reinforcers (Money, praise, ect)
