Assumptions Flashcards
What are the 3 assumptions for the behaviourist approach
-blank slate—> tabula rasas
-behaviour can be learnt through conditioning
-humans and animals, learn in similar ways
What does being born as a blank slate mean?
That we are born with no prior knowledge and understanding, therefore our behaviour is learnt through our surrounding environment
What study shows how humans and animals learn in similar ways
Skinners rats
What happened in skinners rats study?
-Skinner developed operant, conditioning, principles, through using positive reinforcement on rats
-The rats were put in a box, and when they pulled a lever a treat would fall.
-similarly to how parents reward children.
What is positive reinforcement?
Positive reinforcement provides a reward to increase the likelihood of a desired behaviour being repeated.
What is negative reinforcement
The removal of an unpleasant experience to increase the likelihood of the desired behaviour being repeated.
What is operant conditioning?
Learning through consequence
What study supports that we are born as a blank slate slate?
Bandauras bobo, doll study
What is classical conditioning?
Learning through association
What study is an example of classical conditioning?
Pavolovs dogs
What is the classical conditioning process?
- for pavolovs dogs
-food(ucs)—> salivation(ucr)
-bell(ns)—> no response
Bell+food(ucs)—>salivation(ucr)
Bell(cs)—> salivation
What are the three assumptions for the biological approach?
-behaviour can be explained through neurotransmitters
-behaviour can be explained through localisation of brain function
-behaviour can be explained through evolutionary influences
What are the five neurotransmitters and what do they do?
Dopamine—> pleasure, satisfaction
GABA—> inhibits nerve transmission
Serotonin—> mood, sleep, health
Neuroadrenaline—> flight/ fight
Oxytocin—>love hormone, relaxation
How do neurotransmitters work?
Neurotransmitters past chemical messages from one neuron to the next, through synapses.
The neurotransmitters travel from the presynaptic neuron, over the synaptic gap and bond with receptors on the post synaptic neuron.
What are the Four Main brain lobes, and their functions?
-Frontal—> regulates emotion, in control of voluntary movement and expressive language
-Parietal—>processes sensory info
-temporal—> processes auditory info and in control of face recognition
-occipital—> visual processing
What study can be used for localisation of brain function?
-phineaus gague
How does Phineas Gage link to localisation of brain function?
Phineas gauge had a rod, go through his eye and pass through his frontal lobe. After this, he lived a fully functioning life. However, his friends and family reported that his personality had changed, and he had become more and more cold and short tempered.
What does localisation of function mean?
That different regions within our brain or play separate roles, and if impaired can alter our behaviour.
What is evolution?
The changes in inherited characteristics in a population over successive generations.
How does evolution work?
We adapt through natural selection developing traits that are passed on allowing us to survive within our environment.
Which study can be used for the assumption of evolutionary influences?
Buss
- mate selection
What dose busses study show about mate selection?
Buss found that woman prefer men who are strong, physically, fit, wealthy, etc. as this shows how they can provide for the family. He also found that men are attracted to women with breasts, hips, slim, caring, etc. as it indicates they are fertile and can have a child.
