Learning
The process if acquiring theough experience new and relatively enduring information or behaviours
Associative learning
Learning that certain events occur together. The events may be two stimuli (as in classical) or a response and its consequence (as in operant)
Classical conditioning
Process includes pairing neutral stimulus with a response until neutral stimulus elicits same response.
A type of learning in which we link two or more stimuli
Created by Ivan Pavlov
Stimulus
Any event or situation that evokes a response
Respondant behaviour
Behaviour that occurs as an automatic response to some stimulus
Operant conditioning
Type of learning in which a behaviour becomes more likely to reoccur if followed by a reinforcer or less likely to reoccur if followed by a punisher.
- give treat to dig for tricks
- cat in box accidentally oressed lever and lever opened door to food. Car put bscj in and when hungry, opens door on purpose.
Operant behaviour
Behaviour that operates on the environment, producing a consequence
Cognitive learning
Acquisition of mental information, whether by observibg events, by watching othwrs, or through language
Behaviourism
The view that psychology should be an objective science that studies behaviour without reference to mental processes.
- John Watson(founder): focused on envrionment and associated effects as key determinants of learning. (Little albert)
- Ivan Pavlov: classical conditioning
- Skinner: Operant conditioning
- Bandura: Social learning
Neutral stimuli
In classical conditioning, a stimulus that elicits no response before conditioning. Anything seen or heard that must not be associated with unconditioned response
Ex: A tone
Unconditioned response
In classical conditioning, unlearned, naturally occurring response (such as salivating) to an unconditioned stimulus such as food in mouth
Unconditioned stimulus
In classical conditioning, a stimulus that unconditionally, naturally and automatically triggers a unconditioned response without prior learning
Aka food
Before conditioning and after conditioning Dog example
Before:
U.S=food in mouth causes U.R=Salivation
Trials:
N.S=Tone causes no salivation to start
After:
N.S(tone) +U.S(food)=U.R (salivation)
C.S. (Tone)=C.R.(salivation)
Conditioned response
In classical conditioning, a learned response to a previosuly neutral stimulus
Conditioned stimulus
In classical conditioning, an original neutral stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response
Acquisition
In classical conditioning, the inital stage-when one links a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response
-strongest conditioning occurs when CS is presented slightly before US, usally 1/2 second to a fee seconds
Higher-order conditioning
Procedure in which the conditioned stimulus in one conditioning experience is paried with a new neutral stimulus, creating a second (often weaker) conditioned stimulus.
Ex: Tone=Food, theb learns light=tone=food so then light=food
Extinction
Gradual weakening and apparent disappearance of conditioned behaviour
-occurs when the conditioned stimulus is repeatedly presented without the hnconditioned stimulus
Spontaneous recovery
The reappearance after a pause of an extinguished conditioned response
Generalization
The tendency, once a response has been conditioned, for stimuli similar to the conditioned stimulus to elicit similar responses. (In operant-responses learned in one situation occur in other situations)
Ex: salavate to sinilar tones with 1000hz
Discrimination
In classical conditioning, the learned ability to distinguish between conditioned stimulus and similar stimuli that do not signal an unconditioned stimuli (in operant, ability to distinguish responses that are reinforced from similar responses that are not reinforced)
Occurrence of a learned response to a soecific stimulus but not to other, sinular stimuli. Ex: CS (Bell), dog wint salivate to a whistle
Law of effect
Thordikes principle that behaviours followed by favourable consequences become more likely and that behaviours followed by unfavourable consequences become less likley
Operant chamber
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 (skinner box)
Reinforcement
Any event that strengthens the behaviour if follows
