Key Approaches Flashcards
Define bios and logos (origins of the word biology).
Life, study; the study of life.
What are the 5 different approaches?
Biological, behaviourist, cognitive, psychodynamic, humanism.
What are the three main studies of the biological approach?
Physiology, investigation of heritability (genes), and comparative method (studying animals and comparing them to humans).
How many chromosomes are in the human cell nucleus?
46 (23 pairs).
Why are rats and mice used in study?
They have a short gestation period.
What three ways of study can be used to study genes?
Genetic mapping, genetic engineering and selective breeding.
What is the study of genetic aggression?
Bock and Goode found mice reared alone found a strong tendency to attack other male mice when first exposed to other animals.
What is selective breeding?
The artificial selection of male and female animals for a particular trait.
What is a chromosome?
The part of the cell that contains genetic information.
What was the book Darwin wrote and what is it on?
The Origin of Species, about evolution and natural selection.
Give example of evolution.
Animals - male species display traits like mating calls and brightly coloured plumage to attract a mate.
Human - rooting reflex. Babies will turn their heads towards anything they strokes or touches their cheek, helping with breastfeeding.
Is the biological approach nature or nurture? Why?
Nature. Genes, hormones.
Is the biological approach free will or determinism?
Determinism.
Is the biological approach scientific or non-scientific?
Scientific.
What are the applications of the biological approach?
Drug therapy such as anti-depressants.
Is the biological approach reductionist? How?
If explains all behaviours through actions, nerves or chemicals.
What is one ethical issues of the biological approach?
Genetic mapping. Is it right to artificially manipulate genetic make-up?
Is the biological approach too simplistic?
Yes. It doesn’t take into account and environmental factors.
What is tabula rasa, and who used the term?
John Locke described the mind as a tabula rasa, or blank slate. All behaviour is learnt and dependant on interactions with the environment.
Who established behaviourism? Why did he?
John Watson. He opposed the psychodynamic approach and said the consciousness could not be observed or defined so should not be studied.
Edward Thorndike proposed what law?
Law of Effect. If a behaviour is followed be a pleasing effect then that behaviour will be stamped in. However if it is followed by negative consequences it is unlikely to be repeated.
How did Thorndike observe his Law of Effect?
He observed cats trying to escape from puzzle boxes. The only way to escape was to operate a latch to open the door. This caused Skinner to develop his theory.
B.F. Skinner proposed what form of conditioning?
Operant conditioning.
What is operant conditioning?
All behaviour is learnt from consequences in our environment. It uses positive reinforcement, negative reinforcement and punishment. It is an active process where we operate on the environment and behaviour is emitted. Behaviour is harder to predict.
What is the operant conditioning experiment?
Skinners box. A hungry rat was placed into a box, and if he pressed the lever he would receive food as positive reinforcement.
What is positive reinforcement?
It provides a feeling of satisfaction that increases the likelihood of the action being repeated.
What is negative reinforcement?
This is the removal of an unpleasant experience in order to increase the likelihood of an action being repeated.
What is punishment?
The addition of a negative stimulus to prevent an action being repeated.
What are the applications of operant conditioning?
Education, prisons and psychiatric institutions. Modifying speech in autistic children who have under developed speech by using positive reinforcement.
Who proposed classical conditioning and with what experiment?
Pavlov’s dog. While researching the digestive system of dogs he discovered they would always salivate when presented with food. He paired this with the ringing of a bell.
What is classical conditioning?
The pairing of a neutral stimulus with an unconditioned reflex response. It is a passive process, where behaviour is elicited and behaviour is easy to predict.
What is the ‘formula’ for classical conditioning?
- UCS –> UCR
- UCS + CS –> UCR
- CS –> CR
What is another famous experiment for classical conditioning?
Watson and Rayner, the study of Little Albert.
Explain the Little Albert experiment.
When he was 11 months old they used classical conditioning to induce fear of a white rat. They used the reflex response of fear of striking a metal bar with a hammer.
What are some issues with the Little Albert experiment?
Ethical: conditioning fear into a young boy.
Methodological: we can’t generalise one study. It has been hard to replicate this experiment with successful results, especially in adults.
How can classical conditioning be used in real life?
The treatment of atypical behaviour. For example, aversion therapy in the treatment of alcoholism. They are given a drug that causes an unpleasant response such as nausea and vomiting.
Is behaviourism scientific or non-scientific?
Scientific.
Is behaviourism nature or nurture?
Nurture.
Is behaviourism free-will or determinism?
Determinism.
What are some issues with the behaviourist approach?
It ignores possible biological explanations for behaviour.
Is behaviourism reductionistic?
Yes. We are reduced to stimulus and response.
What two approaches is SLT like and how?
It moves away from radical behaviourism and take into account cognitive processes involved in learning.
What are the four mediating cognitive processes? Explain them.
Attention: notice someone in their environment.
Retention: remember what they observed.
Motor reproduction: replicates the behaviour shown by the model.
Motivation: they seek to replicate the behaviour they observed.
What is vicarious reinforcement?
Learning through an observation of another persons experience. For example through TV. This type of learning is indirect.
What two types of models are there? Give an example of each.
Live models: mother, teacher, pop star.
Symbolic models: people present in books, film and television.
What is a problem with vicarious reinforcement?
Not all behaviours observed can be directly reproduced.
What is the famous SLT experiment? Explain it.
Bandura’s Bobo doll experiment. Three to six year old girls and boys were shown a video in which children of a similar age acted aggressively towards a Bobo doll. There were three different endings to the video. The children were then placed in a room with a Bobo doll to see how they behaved.
What were the three endings of the Bobo doll experiment video?
- the adult in the film commented positively.
- the adult commented negatively.
- the adult made no comment at all.
What were the results of the Bobo doll experiment?
Boys showed greater levels of aggression, even when exposed to the same behaviour. Girls were more influenced by the negative comments made by the adult. Children learn by observing models and imitate their behaviour.
What is modelling?
The observation of a model and the imitation of the behaviour observed.
What are mediating cognitive factors?
The mental processes that over in-between a stimulus and response that influence our behaviour.
Is SLT nature or nurture?
Nurture.Not as strongly as behaviourism as it takes into account cognitive factors.
Is SLT free-will or deterministic?
Determinism.
Is SLT scientific or non-scientific?
Scientific.
