3-Learning Flashcards
LEARNING
The acquisition, from experience, of new knowledge, skills, or responses that results in a relatively permanent change in the state of the learner
Instincts and reflects
- complex set of behaviours that are shown by every animal in the species
- Unlearned
- Helps keep a species alive
where are reflexes processed
Reflexes are processed by nerve bundles in your spinal cord
- Sensory neutrons send signal to spinal cord, then to motor neurons
- Doesn’t even touch the cortex
difference between reflexes and instincts
- Instincts are complex behaviours, triggered by a broad range of events
- Involve higher brain centres
- Reflects are relatively simple motor/neural responses
- Localized (Eg hand or knee)
ASSOCIATIVE LEARNING
making Connections between stimuli or events that occur together in the environment
CLASSICAL/PAVLOVIAN CONDITIONING
type of learning whereby a neutral stimulus produces a response after being paired with a stimulus that naturally produces that response
Unconditioned stimulus (US)
stimulus that naturally causes a response (happy music)
Unconditioned response (UR)
a natural response in response to the stimulus
Neutral stimulus (NS)
does not naturally cause a given response
Conditioned stimulus (CS)
once the NS is paired with the US such that the NS Elicits a response
Conditioned response (CR)
the response in relation to the NS/CS
acquisition
- learn to associate the NS with the UCS. During this time, the NS begins to create the response
- Initial period of learning
- The closer the pair is to each other (NS and UCS), the faster the learning
- For aversive (negative) conditioning, longer time lags can still lead to learning
- Served an evolutionary purpose—prepared learning
extinction
decrease in the conditioned response when the UCS is no longer presented with the CS
spontaneous recovery
a brief resurgence of the conditioned response to the conditioned stimulus
generalization
when a conditioned response is evoked by a stimulus that is similar to the original conditioned stimulus
discrimination
- When a conditioned response is not evoked by a stimulus that is similar to the original
- Weakened response (part of generalization) and no response
Higher-order/second-order conditioning
when you use the conditioned stimulus to condition another stimulus
Habituation
occurs when we learn not to respond to a stimulus that is presented repeatedly without change
law of effect
Behaviours followed by…
- Positive outcome are likely to be repeated (duh)
- Negative outcome are unlikely to be repeated
OPERANT CONDITIONING
organisms learn to associate events—a behaviour and its consequence
REINFORCER
Anything that increases the likelihood that a target behaviour will be repeated
PUNISHER
Anything that decreases the likelihood that a target behaviour will be repeated
POSITIVE
when something is added
