Approaches: The Learning Approach Flashcards
Who were the three psychologists who largely worked on the learning approach?
•Pavlov
• Skinner
•Watson
What are me main assumptions of the learning approach?
-The main assumption of the learning approach is that all behaviour is learned and we have a birth is the capacity to learn
-From this viewpoint, a person is the product of their environment, and born a blank slate: Tabula Rasa
-This puts The learning approach at the extreme nurture end of the nature nurture debate
-The learning approach also argues that an order for psychology to be scientific. It should focus on observable behaviour which can be objectively measured rather than on things like cognitive processes which can only be inferred.
What does the acronym CIA stand for?::
C: consequences (operant conditioning)
I: imitation (slt)
A: association (classical conditioning)
Pavlovs research:
Pavlov carried out research to see if his laboratory dogs could learn to salivate in response to a bell. Pavlov (1902) started from the idea that there are some things that are dog does not need to learn. For example, dogs don’t learn to salivate when they see food. This reflects is hardwired into the dog to help them digest and break down food. In behaviourist terms, it is unconditioned response, I.e. stimulus response connection that requires no learning.Pavlov carefully measured the volume of saliva produced from the dogs in response to food and or a bell
 
Define extinction and give an example relating to Pavlov
If the condition stimulus is continually presented without the unconditioned stimulus, then the conditions response gradually dies out or extinguish. For example, no salivation to the bell sound anymore.
Define spontaneous recovery and give an example relating to Pavlov
If I conditioned response is not reinforced, it becomes extinguished. But after a period of rest, the response may suddenly reappear. For example, hearing the bell after a week of no salivation And then, starting to salivate again
Define discrimination stimulus and give an example relating to Pavlov
The conditioned response is produced only by presentation of the original stimulus it doesn’t extend to similar stimuli. Only reacting to a particular tone of bell
Define generalisation and give an example.
Extension of CR from theoriginal stimulus to similar stimuli.E.g. Salivation at all types of bell.
Define one trial learning and give an example
When conditioning occurs immediately, after one trial learning. e.g. food poisoning- never eat that food again
Outline Skinners research
Skinner called learning from consequences operant conditioning. Essentially theory is that the likelihood of future behaviour is determined by the consequences of past behaviour. This means ‘behavioural expression is determined by its consequences’. In common with Watson, Skinner did not think it necessary to speculate on what went on in people’s minds. Throughout his research he used what had become known has skinner boxes with pigeons and rats and carefully measured the frequency of selected behaviour
Primary reinforcers…
Anything that fulfils a basic/biological need.
E.g., food fulfils hunger and water fulfils thirst.
Secondary reinforcers…
not inherently reinforcing, it only becomes a reinforcer because it is associated with a primary reinforcer.
E.g., caregiver gives the food that fulfils hunger.
Continuous reinforcement….
Desired behaviour is reinforced every single time it occurs.
E.g., rats gets a food pellet every time it presses the lever.
Partial reinforcement….
Desired behaviour is reinforced only part or some of the time.
Fixed ratio schedule - a rat gets a food pellet after 5 lever presses.
Variable ratio schedule - a rat gets a food pellet after a number of lever presses that changes all the time.
What is positive reinforcement?
Increasing the frequency of a desired behaviour by giving pleasant consequences.
Skinner’s research - when the rat pressed a lever it dispensed food into the box.
Other examples - giving a dog a treat when they give you their paw to shake / a teacher giving students a sticker when they complete a piece of homework really well.
What is negative reinforcement?
Increasing the frequency of a desired behaviour by removing something unpleasant.
Skinner’s research - the rat had to press the lever to turn off the electric current running through the floor so they would stop receiving electric shocks.
Other examples - having a shower so that people don’t think you stink / tidying your bedroom so that you can have your phone back.
Define punishment with examples
Decreasing the frequency of a desired behaviour by giving unpleasant consequences.
Skinner’s research - when the rat pressed a lever they received an electric shock so never pressed the lever again.
Other examples - you skip school and get grounded by your parents / you misbehave in class and get a detention / you commit a crime and go to prison.
Evaluation of behaviourist approach (general): evidence
There is lots of credible evidence to support the behaviourist approach.
Little Albert was conditioned to fear rats. Through pairing rats (NS) with an unpleasant stimulus of a loud bang (UCS), after 7 pairings Albert showed fear in response to the rat. Watson & Rayner had used CC to teach/condition a fear response.
This means the approach has evidence to validate its claims, and can be seen as falsifiable.
