Paradigms and Psychology as related to abnormal behavior and classification (psych notes)

Biological paradigm - medical/disease model. eg. Diabetes is also a condition that is responsive to what happens in the environment eg. amount of sugar entering the body. Another disease is PKU an enzyme deficiency. An amino acid specific if positive test in children - diet low in the amino acid is prescribed. Amino acids get metabilized. R1 plus R2 > Product. Without proper enzymes R slow with proper enzymes million x faster. Phenomenally > use foods that don’t contain. Biology provides person with potential for behaviour individual will learn to perform/exhibit. This is mechanism that takes in what is happening in environment and determine what the behaviour will be. eg. We all are born with ability to learn languages. There is a critical period of time to learn language. A donkey won’t be able to learn language because does not have the biology. As we learn more, one more connection made between neurons. More nerve cells at birth than two years later or more. Use it or lose it. Learning new language - don’t hear the accent. Evaluating biological paradigm, comment on reductionism. Predicting earthquakes on leves of plates. Can’t predict earthquakes by physical layers of earth - however * reductionism - recall as you get more elements within a system you start to get more elements and that gets dynamic of your own. If your car does not start you do not call the physics department. You call a mechanic - those same - many more elements. Biological methods to treatment: Brain is an organ of behaviour. As times goes on more biological to change behaviour. Large techniques for resetting EEG rhythm in abnormal people eg. anxiety, depression and chronic pain syndrome - osculation in brain waves have been identified as marking- can reset- stays for four or five months - not dangerous. No side effects that others have progress with biological treatment - major advance more specific types. eg. serotonin 5-HT a few families of receptors [ _ ] > [ ____ ] (my diagram attempts need work) The old fits in new way - more receptors to fit. Dopamine in schizophrenic - too many. Receptors in the brain - so lets find way to block receptors. The problem with early dopamine, blocking agents - many severe side effects. Have found - dopamine receptors D 1 2 3 psycho 4 5 6 before blocked everything. Now reduced to control problematic receptors. to be continued ……. Frued Id, Ego, Super ego. Anxiety - Egos’s reaction to danger in external world - defence mechanism.Retreating to behaviour patterns of an earlier age.
