Approaches Flashcards
What is included in the origins of psychology?
Wundt, introspection and the emergence of psychology as a science.
Who was Wilhelm Wundt?
Cited as one of the founders of psychology and believed the human mind could be studied scientifically
He founded the institute of experimental psychology in 1879 in Germany. He was credited with making psychology more scientific.
He aimed to study the structure of the human mind and break them down into basic elements - structuralism.
He used a key technique called introspection.
What is introspection?
Investigating events by examining thoughts and feelings as a form of data collection. Systematic analysis of our own conscious experience of a stimulus. Allows us to report our own inner thoughts and feelings in terms of intensity, duration and quality.
What did Wundt believe?
All human behaviours and mental processes can be studied this way in the controlled setting of his laboratory. He did claim some complex mental processes may not be suited to such controlled environments. His study of mental and emotional processes relied on a concept known as empiricism.
What is empiricism?
Means that knowledge and abilities come from observation and experience alone, rather than innate. Believes that all behaviour has causes, and therefore behaviour can be predicted. To explore such assumptions, the scientific method was used.
What is the scientific method?
It is the hypothetico-Deductive model
It is the hypothetico-Deductive model?
An observation is made of a phenomena in the world.
A theory is developed to explain the observation and a hypothesis is developed.
A hypothesis is tested using empirical methods.
Results are analysed to evaluate whether the hypothesis is supported or not.
This is used to refine or modify the theory.
What features of science could Wundt’s work be characterised by?
FROGS
Falsifiable
Replicable
Objective
General laws
Systematic
What does falsifiable mean?
All theories and research must be capable of being tested and potentially disproved, which is more scientific.
What does replicable mean?
Research procedures should be capable of being repeated to check the consistency of the findings - standardised.
What does objective mean?
Should be observable and measurable on an agreed scale so it is not open to interpretation.
What are general laws?
Basic generalisable principles about human or animal behaviour
What does systematic mean?
Recordings are carried out in a controlled and orderly manner using direct observations
Are the origins of psychology scientific?
It has led to useful general laws. Hunter in 2003 used introspection with teenagers to identify what makes them happy or unhappy. By questioning their own thoughts, they were able to identify that when energies were focussed on challenging tasks, they were far more upbeat.
Led to psychology getting more attention as a discipline.
Are the origins of psychology subjective?
Introspection introduces personal opinions and beliefs. Limited when trying to create general laws about the causes of behaviour in this manner.
Lack of numerical data limits the statistical analysis. FMRI scans could be used more objectively to detect changes in the brain.
Shows introspection lacks scientific rigour.
Is the origins of psychology helpful in improving our understanding?
Wundt tried to apply the rigour of natural sciences to the study of human behaviour. He used systematic observation and experimentation on human and animal behaviour using an evidence based approach. This helps our understanding.
Is Wundt’s scientific approach in the origins of psychology generalisable?
Introspection is in artificially contrived environments fail to fully represent real life experiences, so lack ecological validity.
Similar with other methods designed to measure thoughts, intentions and behaviour in a scientific way.
Control needed to make this scientific takes away from the realism of the task.
What are the assumptions of the biological approach?
All behaviour is driven by physical factors and has its roots in biological functioning.
Suggests that genetic factors, biological structures and neurochemistry seems to drive all of our behaviour.
Emphasises our nature in shaping behaviour.
It is probably the most scientific as it uses precise measurements.
What is evolution?
The gradual change within a species over several generations in response to environmental pressures.
What is natural selection?
The process where inherited characteristics that enhance survival are passed on to the next generation - this occurs over thousands of generations.
What does adaptive mean?
Refers to a behaviour or trait that will increase the chance of survival and boost reproductive success
How does evolution and behaviour link to the biological approach?
According to Darwin, natural selection ensures that only those behaviours that are adaptive will be naturally selected and passed down through generations.
Seligman suggests that there was a biological preparedness to phobias of certain things due to an innate tendency to rapidly acquire a phobia to potentially harmful phenomena.
Some behaviours are seen as highly adaptive - showing a fear to a massive spider would lead to better survival rates.
What is a genotype?
The genetic constitution of an individual. The variation in human genotype can account for enormous variation across the species.
What is a phenotype?
The result of interactions between inherited characteristics and inherited material and the environment - this is then expressed through physical, behavioural and psychological characteristics.
What is PKU research in reference to the biological approach?
A disorder that can cause learning difficulties in those who carry the genotype. It causes a deficiency of the enzyme that is needed to process phenylalanine and a dangerous build up of this can develop if a person eats protein rich food, which can damage nerve cells in the brain. If detected early enough, a child can be placed on a restricted diet. Genotype + environment leads to the phenotype.
Genetic inheritance of OCD in reference to the biological approach?
Polygenic condition and an individual with one of the candidate genes may experience OCD. Nestadt did a twin study and found a concordance rate of 67% for MZ twins but only 31% for DZ twins. Suggests that the closer the genetic relationship to a sufferer, the greater the risk of developing OCD.
