Learning Flashcards
Learning
- refers to any enduring change in the way an organism responds based on its experience
- is about predicting the future from past experienceand using these predictions to guide behaviour.
Conditioning
learn associations between stimuli (events) in the environment that reliably predict other stimuli…(especially those stimuli that relate to survival)
Classical conditioning
- Learning an association between a stimulus that reliably predicts another stimulus that is naturally associated with a defensive or appetitive reflex response
- learning to produce a reflex response
Neutral stimulus
A stimulus that doesn’t produce a respond
Normal Reflex pathway?
UCS+UCR= Reflex
Stimulus generalisation
When a stimuli that is similar to a preregister stimuli, the respond is the same
Extinction
The process of removing a learned relex(CS)
What do spontaneous recovery and rapid reacquisition suggest about the extinction process?
It show that a reflex is never truly forgotten
Operant Conditioning
Behaviouris shaped by the learner’s history of experiencing rewards and punishments for their actions.
Reinforcement
A behavior is reinforced(strengthened) whenever a desirable outcome occurs as a consequence of performing the behaviour.
Behaviours that are reinforced are more likely to be repeated.
reinforcer
is any consequence of a behaviour that makes that behaviour more likely to recur in future.
Positive and Negative reinforcement
- Positive Reinforcement = An animal will learn to produce a behaviour if the consequence of doing so is receiving something pleasant.
- Negative Reinforcement = An animal will learn to produce a behavior if the consequence of doing so is stopping something unpleasant.
Continuous vs. Partial Reinforcement Schedules
Partial is more effective as the organism wouldn’t know when the reinforcement will come=> led to them keep trying.
when reinforcement is stopped, behavior that was partial reinforce stick longer compare to continuous
Extinction
-occurs when reinforcement is withheld
-Not immediate, in fact there may be a brief increase in responding referred to as an extinction burst followed by decrease in trained behaviour.
Then an increase in more variable behaviour(ideal for shaping).
Punishment
A behavior is punished(weakened) whenever an undesirable outcome occurs as a consequence of performing the behaviour.
Behavioursthat are punished are less likely to be repeated.
