what are the advantages of the biological model of phychiatry?

Answer 1

If you're going to study psychiatry and psychology at least learn how to spell it. Your question is virtually meaningless. But we do know that hormones have a blanket effect on the whole of the human body or whole systems. Hormones like cortisol have a blanket effect on the nervous system including the brain - this helps us understand the physiological effects of stress for example. A study done in the Netherlands some years ago on rodents who are particular sensitive to cortisol - died when their cortisol levels went up high - through stress. We suspect - the same hormone suppresses the immune system in humans and causes many illness or at least makes them worse. Best I can do - make your questions clearer for clearer answers.....

Answer 2

If psychiatric disorders have a biological basis, then the moral blame for having a sick mind can be eliminated, at least over time. People used to think schizophrenics were possessed by evil spirits. We now know that they have all kinds of bizarre chemical imbalances in their brains, and even that their brains are built differently. We now see them as victims of a biological disorder, which certainly has improved their care. For one thing, it (the biological model) led to medications that are very effective in treating the halluncinations and other symptoms of schizophrenia. As genetic research and brain research progresses, more and more behaviors can be shown to have a biological basis. This in turn leads to new medications, and a reduction in the stigma attached to the mentally ill. It's not a bad model.

Answer 3

I doubt it, or at least I've never heard of it in any actual ecosystem. It seems unlikely, because while it may be beneficial in very large populations, in smaller populations of a particular species it would do the opposite, and prevent the species from populating. So if homosexuality were impactful enough to alter a population's growth rate, it would only be beneficial if it were more prominent in large populations than in small populations. But since there's no evidence to suggest that larger populations of any animal have a higher rate of homosexuality (if any animals are actually exclusively homosexual), then I'd be very doubtful that homosexuality serves any ecological funtion
