Who was the first ‘Psychologist’?
Wundt (1832-1920)
He believed all aspects of nature, including the human mind can be studied scientifically.
What technique was used by Wundt?
Wundt used a technique called introspection.
(Do NOT need the exact definition - just the section in capitals)
This is the process where a person gains knowledge about his or her OWN MENTAL STATES as a result of the OBSERVATION OF THEIR OWN conscious THOUGHTS OR FEELINGS
What is Empiricism?
The scientific method where knowledge is derived from experience.
Outline one criticism of Wundt’s contribution to psychology. (3 marks)
NOTE: This is an actual possible exam question, make sure to make all points listed
- Criticisms mainly from BEHAVOURISTS
- introspection is unreliable due to it being ‘unobservable’
- we have very little knowledge of why we do things
Classical conditioning key study
Association
Pavlov's Dog's: NS = Neutral stimulus (bell) UCS = Unconditioned stimulus (food) UCR = Unconditioned response (salivation) CS = Conditioned stimulus (bell) CR = Conditioned response (salvation)
NS + UCS = UCR
eventually
NS (CS) = CR
Operant conditioning key study
Reinforcement/punishment
Skinner’s Box
A rat is placed in a box, when it presses a leaver a food pellet (the reinforcer) is dropped into the box. The rat then learns to obtain food it must press the leaver. If the food pellets stop the rat tries the leaver a few more times then abandons it (extinction).
What are the two types of reinforcement?
Positive reinforcement - adding something, e.g. praising a child or giving an animal food when they do something well
Negative reinforcement - removal of unpleasant stimulus e.g. pressing the ‘off’ button on an alarm to stop the ringing.
What are two other features of classical conditioning?
NOTE: I have listed 4, only 2 are needed
- timing - if the time interval between NS and UCS is too great conditioning will not take place.
- extinction - Pavlov discovered that if the association of the CS is stopped the CR will also stop
- spontaneous recovery - following extinction if the CS and UCS are then paired together again the link is made much more quickly
- stimulus generalisation - Pavlov discovered once an animal has been conditioned they will also respond to other stimuli that are similar to the CS
Social learning theory key study
Bandura’s Bobo doll
children observed aggressive or non-aggressive adult models and were then tested for imitative learning in the absence of the model.
Children who observed the aggressive model reproduced a good deal of behaviour resembling the model, children who observed the non-aggressive models exhibited virtually no aggressive behaviour towards the Bobo doll
Define ‘identification’
A form of influence where an individual adopts an attitude or behaviour because they want to be associated with a particular group or person.
Define ‘imitation’
The action of using someone or something as a model and copying their behaviour
Define ‘modelling’
A form of learning where individuals learn a particular behaviour by observing another individual performing that behaviour
Define ‘social learning theory’
learning through observing others and imitating behaviours that are rewarded
Define ‘vicarious reinforcement’
Learning that is not a result of direct reinforcement of behaviour, but through observing someone else being reinforced for that behaviour
What is the role of a schema?
A schema is a cognitive framework that helps organise and interpret information in the brain.
A group of information which allows us to act accordingly e.g. mental interpretation of how to act at a festival vs in a church.
What does the cognitive approach compare or use to explain mental processes?
This approach compares mental processes and memory to a computer model. The hard-disk would represent the long-term memory, the RAM would represent the working memory as on a computer the RAM functions on limited capacity to carry out specific tasks.
What is the main focus of neuroscience?
cognitive neuroscience is dedicated to underlying neurons in the human body. These neurons can be tested via PET scans and fMRI scans.
What is an issue with cognitive psychology research?
some studies may lack ecological validity, for example it is not normal for someone to record how many random word lists or digits they can remember for a specific amount of time.
What is the biological approach?
the biological approach views humans as biological organisms. it focuses mainly on genetics and evolution.
What is the difference between genotype and phenotype?
Genotype is the genetic makeup of an individual - DNA which determines our genetic outcome.
Phenotype is the observable characteristics of an individual - these are consequences of our genotype and the environment.
What does neurochemistry refer to?
neurochemistry refers to neural and chemical processes in the nervous system.
What are the two nervous systems in the human body and what are their purposes?
the central nervous system (CNS) consists of the brain and spinal cord.
the peripheral nervous system (PNS) consists of the somatic and autonomic nervous systems.
the nervous system is responsible for carrying messages from one part of the body to another as well as controlling breathing, eating and sexual behaviour.
what is the frontal lobe responsible for?
the frontal lobe is responsible for speech, thought and learning
what is the temporal lobe responsible for?
hearing and memory
