The genes adopt behaviour to the environment; our intelligence depends on the genetic make-up. It is found that environmental toxins and recreational drugs can cause problems for the health due to chemical poisoning. Infection is the result of pathogens entering the blood stream and entering the blood brain barrier or the nervous system. Changes in the body's balance of hormones may be involved in causing or triggering depression and can be a result of menopause or a thyroid problem. Psychotherapy versus medication for depression: Challenging the conventional wisdom with data. Accidental brain damage can lead to psychological disorders. All of these involve comparing people with different degrees of genetic relatedness to see how similar they are in relation to a particular trait or behaviour.
This is shown through the Bobo Doll studies by Bandura and Ross. In conclusion, it is very effective to explain aggression through the biological perspective since there are many aspects that control aggression such as hormones and even parts of the brain. The model as 4 different elements that may be the cause of psychological abnormalities; viral infections, biochemistry, brain damage, genetic factors. Several meta-analytic reviews of studies comparing benefits and efficacy of treatments for depression have found that psychotherapy treatments are the most safe and long lasting choice and also raise concerns about the antidepressants side effects. Section One — 1 When psychology first began to become a science in 1860, it was more of a field of philosophy than an actual medical study.
Presented here it is a critical evaluation of biological approach for treatment of depression. Psychology is the scientific study of the behavior of humans and animals. . It is my personal belief that biology has a great deal to do with mental illness. These biological markers are what researchers look for when examining the brain. It is nearly twice as many as men. As side effects, patients can develop heart irregularities due a blockage of some sodium channels as well drowsiness, dry mouth and difficult to urinate since histamine and acetylchoine receptors can also be blocked.
Use free sample essays on biological perspective to understand that the idea of parallelism of psychic phenomena with the physiological processes in the nervous system was proved by a huge number of observations and experiments, proving that the damage to different centers of the brain, cranial or abducens nerves immediately distorts or destroys any mental functions with the full and detailed definitions, besides, it is not hard to see how close is the psychological development and the development of neuro-cerebral apparatus in the number of animals or in the human development from embryo to a mature man. This idea was supported by Claudius Galen, who was the most influential physician of the Roman Empire. Accordingly both normal and abnormal behaviors may involve a component inherited from biological parents. The majority of studies on depression has been finding positive answers for biological markers connected to hormonal responses to stress that are related to the hypothalamic-pituitary-adrenal system. This hormone was investigated by Dabbs et al, where testosterone levels in prisoners where compared to the level of crime committed. The causal level of analysis incorporates physiological explanations, such as the effect of nerves and hormones on behaviour. There are many different types of gene research such as; Genetic mapping where the genes responsible of each behaviour and function are tracked, genetic engineering where the genetic code is altered to change or eliminate a function or to measure the effects on behaviour and selective breeding where the genetic code is manipulated to produce a prime specimen within a species.
Words: 768 - Pages: 4. It was not until the 18th century that psychologists began to argue that this behaviour should be treated as an illness and medical techniques could be used to treat it; and so emerged the medical model of abnormality. The behavioural approach believes all behaviour is learnt through conditioning, there are two types of conditioning. The causal level of analysis incorporates physiological explanations, such as the effect of nerves and hormones on behaviour. Yet, further studies have failed to confirm this link; Wilkin et al 1976 found that only 12 men in a large sample of 4500 males had the extra Y chromosome, with none being an offender. The most friendly and social monkeys had the highest serotonin levels.
The counselling must be undertaken in a safe environment where the change that occurs within the client is based on a personal level and not in a social context 2008. Extensive research and studies show that natural remedies are better than antidepressants for treating depression because there are fewer side effects, more health benefits and according to most studies, antidepressants are no more effective than placebos. According to biological psychologists, behaviour is controlled by the nervous system, which consists of the central nervous system the brain and the spinal cord and the peripheral nervous system the surrounding nerves , which itself includes the autonomic nervous system that controls automatic processes such as heart rate and the fight or flight syndrome. Strengths and Weaknesses of Biological Explanations of Criminal Behaviour Positivist criminology began towards the late 18th century and early 19th century and contrasted with Cesare Becharios early ideas of classicism. These individuals are also said to be high on the neuroticism dimension, with high anxiety levels and an emotionally unstable central nervous system.
The approach does not explain the thought process and bring into account free will. However antidepressant drugs provide an effective and inexpensive help, studies have found that the behavioural effects of these drugs could take over two weeks before showing any benefit and any perceived effect before this period would be a placebo effect Kalat, 2001. The nervous system can also be studied by manipulating the brain surgically. Psychology Essay- Discuss the effectiveness of the biological perspective in explaining one psychological or social question. Lower levels increased impulsiveness and aggressiveness in animals whereas higher levels decreased the amount of aggression. Within the central nervous system, neurons communicate with each other via sending chemical impulses, neurotransmitters, across synapses.
Charles Darwin took human biology a step further. The psychoanalytic approach is an approach to psychology proposed by Freud 1971. These three areas give explanations on why the offender commits acts of criminal activity and also help to provide answers to why there is crime in society. There is no solid evidence of long-term memory loss problems after electro convulsive therapy but many patients experience confusion on waking up from the anaesthetic, but this usually clears within a few hours. It is no secret that psychotropic medications have been a great advancement and advantage in the treatment of abnormal behavior.
It is also difficult finding a large samples of participants for twin studies. Historical Beginnings Historically, biopsychology can be dated back to the Ancient Greeks. Also, this focuses on experiences that you have had in different areas of life. Paul Broca 1860 discovered by examining the behavioural deficits of people with brain damage that people's personality can be changes if they suffer from brain damage. The biological model argues that inheritance of developmental abnormality is a possible cause for psychopathology.
The nature-nurture debate highlights a key argument in psychology, over the relative influence of biology and environment on the characteristics of an individual; an extreme biological approach assumes that these are determined solely by nature. Maslow believed that all humans need to fulfill needs of human nature such as love, esteem, and self-fulfillment. But the environment can also affect brain activity. In the 20th century, behaviorism was introduced. This signal triggers the release of adrenaline from the adrenal glands. This is known as direct reinforcement.
