Learning Flashcards
What is learning?
Relatively permanent change that is the result of an experience
What is classical conditioning?
The pairing of 2 stimuli that results in a learned response
What is an unconditioned stimulus?
Anything that reliably produces a naturally occurring reaction
What is an unconditioned response?
An automatic reaction produced by the unconditioned stimuli
What is a neutral stimulus?
A stimulus that initially produces no response
What is a conditioned stimulus?
Initially, a neutral stimulus that has now been associated with with the unconditioned stimulus
What is a conditioned response?
Reaction that resembles the unconditioned response but is caused by the conditioned stimulus
What were 2 studies conducted uncovering classical conditioning?
- Pavlov’s Dogs
- Little Albert
What Was the aim of Pavlov’s experiment?
To test his hypothesis of the dogs associating the footsteps with food, by replacing the footsteps with a bell, seeing the resulting behaviour
What were the methods of Pavlov’s experiment?
A bell was rung before feeding the dogs and this was repeated many times
What were the results of Pavlov’s experiment?
- Originally the dogs only salivated when seeing or smelling food
- Soon the dogs would drool whenever the bell was rung even when food wasn’t present
What were the conclusions of Pavlov’s experiment?
The dogs unconsciously associated the bell stimulus with the stimulus of the food, resulting in the same unconscious response for both stimuli.
What does extinction mean?
The gradual elimination of a learned response that occurs when the unconditioned stimulus is no longer presented with the neutral stimulus
What does spontaneous recovery mean?
Describes how a conditioned behaviour can be recovered from extinction after a rest period (like relearning, happens faster 2nd time)
What does stimulus generalisation mean?
When the conditioned response still occurs even when the conditioned stimulus is slightly different
What does discrimination mean?
Capacity to distinguish between similar but distinct stimuli
Who conducted the Little Albert experiment?
Watson & Rayner
What was the aim in the Little Albert experiment?
To find out if an infant could be classically conditioned
What were the methods of the Little Albert experiment?
- 8 month old presented with many stimuli, was unafraid of all of them
- 2 months after the baseline session, a conditioning session was conducted where Albert was shown a white rat paired with a loud banging sound
What were the results of the Little Albert experiment?
- After pairing the loud noise with the rat, Albert only needed to be shown the rat without the loud noises to display signs of fear and avoidance
- Fear faded as time went on but the association could be relearned by repeating the procedure
- Albert developed phobias of objects with similar characteristics to the rat, generalisation occured
What were 3 limitations of the Little Albert experiment?
- Loud noise could have made Albert fear any object in the laboratory setting
- Alberts’s responses were inconsistent, much calmer when allowed to suck on his thumb
- As it is a case study there was no control and results cannot be generalised
What principle is operant conditioning based off?
Behaviour is increased through reinforcement and decreased through punishment
What are 3 things that need to be present for behaviours to occur consistently?
- Antecedent: The stimulus that triggers a desired behaviour
- Behaviour: The desired action made by the animal
- Consequence: the reward or punishment recieved for the behaviour
What is reinforcement?
A consequence that increases the likelihood of a behaviour
Name and describe the 2 types of reinforcement
- Positive reinforcement: The addition of a positive stimulus
- Negative reinforcement: The removal of a negative stimulus
What is punishment?
A consequence that decreases the likelihood of a behaviour
Name and describe the 2 types of punishment
- Positive punishment: The addition of a negative stimulus
- Negative punishment: Removal of a positive stimulus
