A literal ton of research has been done on the causes of depression. Below is a brief discussion of the multiple biological, psychological and social factors that have been identified as being related to the development of depression. In context of the Diathesis-Stress hypothesis, the biological factors typically function as diatheses, the psychological factors may serve as diatheses or stressors, and sociological factors tend to function as stressors or triggers.

If a single problem has vexed biologists for the past couple of hundred years, surely it concerns the relation between biology and physics.
The former, reductionist aim can easily seem to ignore what is special about living creatures — and above all to ignore the way meaningful human experience seems to transcend the kind of lawfulness we observe in inanimate physical objects.
But, on the other hand, scientists who attempt to articulate a principle differentiating the living from the non-living have all too often posited some kind of special matter or vital force that no one ever seems able to identify.
I have shown in previous articles that, whatever their belief in these matters, biologists today — and molecular biologists in particular — routinely and unavoidably describe the organism in terms that go far beyond the language of physics and chemistry.
But they are always employed in attempts to understand the living organism.
Further, I have pointed out that such descriptions, rooted as they are in the observable character of the organism, show no sign of being reducible to less living terms or to the language of mechanism.
But this immediately raises a suspicion of vitalism in the minds of many scientists. Who, after all, is this organism? Bear in mind, however, that these questions press just as urgently upon the conventional molecular biologist as on the suspected vitalist.
After all, the loaded terminology comes straight from the laboratory, where researchers are trying to make sense of what they see. A subject possessing a power of agency adequate to regulate or coordinate at the level of the whole organism looks for all the world like what has traditionally been called a being.
But you will not find biologists speaking of beings.
What, or who, is capable of all the highly directed activity of cell and organism? We will leave aside for the time being any features of that agency other than ones for which the life scientist has vouched. To think of it positively: After all, a lot of experiment and observation has led to this language; if we start with it, we will surely gain valuable clues about the being of the organism.
For example, the language tells us that every organism discriminates in many circumstances between health on the one hand and disease or injury on the other, and acts flexibly and intelligently — within its own limits and based on the particulars of its disorder which may involve conditions it has never encountered before — to restore health.
More generally, it pursues a coherent path of development and self-maintenance, and manages to produce new life from existing life via intricate processes at the molecular, cellular, and behavioral levels. If the biological literature is to be believed, the organism is a being who in some sense perceives, knows, and responds appropriately to the meanings of diverse stimuli.
And it may even participate in a superordinate self: Such, at least, is the being we are handed by biologists. Not unanimously in all details, to be sure, and in need of critical assessment without a doubt. Our aim is to locate this being of the organism a little more comfortably within the landscape of an acceptable science — locate it in a way that remains faithful to observation while sparing biologists any embarrassment at their own language.Describe and evaluate biological explanations of schizophrenia (24 marks) Schizophrenia is a psychotic disorder characterized by distorted thinking, impaired emotional responses, poor interpersonal skills and a distortion of reality.
It is the most common of psychotic disorders that, in most countries around the world, affects around 1 per cent of the population. Below is a brief discussion of the multiple biological, psychological and social factors that have been identified as being related to the development of depression.
In context of the Diathesis-Stress hypothesis, the biological factors typically function as diatheses, the psychological factors may serve as diatheses or stressors, and.
In this essay, I’ll discuss the main reasons that contribute the stress in the banking industry (particularly in the UK), the effects of stress on different parties and how the financial institutions and individuals somehow manage to reduce the stress resulted from their workload. Jun 26, · Introduction In this assignment I am going to compare some areas of molecular revolution with genomics revolution.
