learning approach Flashcards
What is Classical conditioning?
A form of learning through association. takes place when we associate two stimuli together.
What is the unconditioned stimulus?
a stimuli that triggers a unlearned response. e.g. a dog salivating when it sees food (the stimulus)
What is an unconditioned response?
An unlearned response to a stimulus. e.g. a dog salivating (unconditioned response) at the sigh of food.
What is a neutral stimulus?
A stimulus that doesn’t produce a wanted response. e.g. the sound of a bell will not make a dog salivate before conditioning.
How did Pavlov condition his dogs to salivate at the sound of a bell?
Pavlov repeatedly exposed his dogs to the unconditioned stimulus (food) and the neutral stimulus (bell) at the same time so that the dogs eventually learned to associate the neutral stimulus (bell) with the unconditioned stimulus (food). After enough pairings, the neutral stimulus (bell) on its own produces the same response as the unconditioned stimulus (food). This means that the neutral stimulus (food) is now a conditioned stimulus and the response it produces (salvation) is an unconditioned response.
What is operant conditioning?
when we form links between a behaviour (the operant) and its consequences (the response)
What is positive reinforcement?
occurs when behaviour is followed by a pleasant consequence. reward can be tangible e.g. food or money or intangible e.g. a smile or compliment.
What is negative reinforcement?
Occurs when behaviour is followed by the removal of an unpleasant stimulus e.g. the removal of an annoying noise
What is positive punishment?
when a behaviour is followed by an unpleasant consequence e.g. a slap or harsh words.
What is a negative punishment?
occurs when behaviour is followed by the removal or something pleasant e.g. being fined or grounded
What does reinforcement do?
reinforcement increases the probability of behaviour being repeated.
What does Punishment do?
makes it less likely for a behaviour to be repeated.
What two experiments were conducted for classical conditioning?
- Pavlov’s dogs
- Little Albert
What is the Little Albert experiment and what did they find?
The baby Albert fear experiment. They tested baby Albert for fear reactions, they presented him with a white rat, rabbit, cotton wool, dog etc. and no fears were noted. They then banged a steel bar and he started to cry showing a fear response. Then 2 months later they presented him with the same animals and when he reached out to touch the white rat, they banged the steel bar and he showed a fear reaction by jumping. He then reached out again and the bang happened again and he started to whimper. A week later they continued the experiment and he wouldn’t touch the white rat and even attempted to get away from it. This shows that fear can be s learned response.
Strengths and weaknesses of Little Albert Study.
+good experiment controls
- poor generalisability
- ethical issues
