Learning
A change in behaviour due to the environment.
Aspects to learning
Types of learning
not all changes in behaviour can be attributed to learning (phineas gage)
Classical conditioning
Unconditional Stimulus (US)
a stimulus that naturally and automatically triggers a response without any prior learning or conditioning
Unconditional Response (US)
It is the automatic, reflexive response to the unconditioned stimulus (US) without any prior learning or conditioning
(biologically relevant)
Conditional Stimulus (CS)
A neutral thing that starts making you react because it’s been paired with something else that makes you react automatically.
bell with food
Conditional Response (CR)
When something makes you behave in a certain way because you’ve learned to associate it with a particular situation

Delayed conditioning
(e.g. dog growling => biting (continues growling for a little bit)
details dont seem too important
Trace conditioning
Caveat: Depends on the response being learned.
e.g. flash of light => thunder
Simultaneous Conditioning
Backwards Conditioning
Respondent Extinction:
Presenting the conditional stimulus (CS) in the absence of the unconditional stimulus (US). Results in the gradual reduction of the (CR).
Spontaneous Recovery:
An increase in the magnitude of the conditional response (CR) after respondent extinction has occurred and time has passed.
Demonstrates that extinction is not simply “forgetting” what was learned.
Respondent/Stimulus Generalization
Produces a generalization gradient. (graph of tones and salivation)
Operant/Stimulus Generalization
When an organism responds to values of the discriminative stimulus that are different than the originally trained values.
Produces a generalization gradient. (graph of tones and salivation)
Respondant/Stimulus Discrimination
When values of the CS, other than what was originally trained, elicit little to no conditioned response.
Higher-Order Conditioning:

Aversion Therapy
Difference between respondant and operant conditioning
When the stimulus is administered
Learning: Operant Conditioning

Thorndikes law of effect
behaviors that are followed by positive consequences are more likely to be repeated, while behaviors followed by negative consequences are less likely to be repeated.
