Key Approaches Flashcards
(135 cards)
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.
