Learning
Any process through which experience at one time can alter an individual’s behaviour at a future time
Experience
Any effects of the enviornment that are mediated by individuals sensory systems
Classical Conditioning
A learning process that creates new reflexes.
Reflexes: simple relitively automatic stimulus response produced by nervous system
Habitation
A decline in the magnitude of a reflective response when a stimulus is repeated several times in succession
Ex. Ever decreasing response to jump scares followed by no response to it
Classical Conditioning Procedure
A neutral stimulus initially does not elicit a response. But after it is paired with an unconditioned stimulus for several tries it becomes a conditioned stimulus and does elicit a response.
Extinction
When conditioned stimulus is presented repeatedly without addition of unconditioned stimulus the conditioned response decreases until it is entirely gone
When reinforcement of behaviour ceases and thus behaviour no longer occurs
Spontaneous Recovery
Mere passage of time following extinction can partly renew conditioned response
Single Pairing
A single pairing of conditioned stimulus with unconditioned stimulus (or reinforcement/punishment with behavior) can fully renew the conditioned response following extinction
Generalization
Showing conditioned response to a new stimuli that is similar to the conditioned stimulus.
Magnitude of conditioned response depends on degree of similarity between the new stimuli and the original.
Shows understanding for conceptualisation and of subject similarity.
Discrimination Training
Generalization between 2 stimulus is abolished if response to one is reinforced while the other is extinguished
Behaviorism
Focuses on the relationship between observable events in enviornment (stimuli) and observable behavioral reactions to those events (responses)
Stimulus-Responss Theory
Unconditioned stimulus -> response
Conditioned stimulus -> response
Ex. Rats freeze when there is a light because direct learned connection between light and freezing
Stimulus-Stimulus Theory
Conditioned stimulus -> mental representation of unconditioned stimulus -> response
Ex. Rats freeze because of learned connection between light and a loud sound
Predictive Value of Conditioned Stimulus
Conditioning is dependent on predictability, since response to conditioned stimulus is depended on Expectancy (theory) of receiving unconditioned stimulus.
Evaluative Conditioning
Changes in strength of liking/disliking of a stimulus is a result of it being paired with another positive or negative stimulus
Law of Effect
Edward Lee Thompson
Responses that produce as satisfying effect in a particular situation become more likely to occur again in that situation, while responses that produce a discomforting effect become less likely to occur again in that situation.
Operate Response
Any behavioural act that has some effect on the environment
Operate Conditioning
The process by which the effect of an operate response change the likelihood of the response’s reoccurance
Reinforcer
A stimulus change that follows an operate response and increases the frequency of that response happening again
Increases the likelihood of reoccurance
Conditioned Reinforcers
Stimuli that have reinforcing values only because if previous knowledge
Ex. Money only has a reinforcing value for us to want to work because we know what money can get us
Operate vs Classical Conditioning
Operate: individual emits a behaviour that has some effect on the environment
Classical: a stimulus elicits a response from the individual
Shaping
Successively closer approximations to desired response are reinforced until desired response fully occurs and can then be reinforced
(Reinforcer can only come after subject makes desired response, but if they never do then there can never be a reinforcer.)
Continuous Reinforcement
Response is always reinforced
Used while first training
Partial Reinforcement
Response only sometimes produces reinforcement
