The Biological And Cognitive Approaches

(P1)The biological approach means that our behavior is the cause of biological factors. This approach looks at our genetics to construct a reason why we act the way we do and why we develop abnormal behaviors. The brain and nervous system are the biological approach and so are chemical changes in the body .This can mean chemical reactions in the brain. For instance, in eating disorders - twin studies were carried out and it was shown that if one identical twin suffered from an eating disorder then the other twin would also be more likely to suffer from a disorder as well. This did not happen with non-identical twins, suggesting that the

Cognitive Psychology draws the comparison between the human mind and a computer, suggesting that we like the computer process the information we acquire from around us and then react accordingly. Hearnshaw, (1987), claims that Cognitive Psychology is both one of the oldest and also one of the newest parts of Psychology, cited in ?T. Malim?, (1994). Information is collected through our senses i.e. vision, touch, smell etc and then processed through our

The medical model focuses on the molecular structure of drugs and indicators of mental or emotional disorders. However, the medical model is not effective treating mental and emotional disorders. The medical model indicts the notion that abnormal behavior is the product of physical problems and be treated medically. The medical model depends upon independent tests to demonstrate or contradict if a patient is ill. The psychological model uses tests to demonstrate or contradict whether a patient is ill. It is at this point of agreement that the two models separate. A restriction to the psychological model is if a patient that is unconscious, or their communication ability is compromised to the degree that they are

Cognitive psychology is a pure science based mainly on laboratory experiments and began to revolutionize psychology in the late 1950’s and early 1960’s and became the dominant approach in psychology by the late 1970’s [ (McLeod, 2007) ] according to Saul McLeod. An example of the cognitive perspective would be when one learns to take blood pressure. First you must learn how to manipulate the blood pressure manometer, learn how to hear blood pressure sounds and understand the meaning of the sounds. As each time you practice these activity, you will gain more confidence and competence in performing the task. The strong point of this perspective is that it mostly uses rigorous scientific methods and the approach has had many practical applications. The weakness of this perspective is that it is to simplistic. It ignores the complexity of the human function, biological influences of the human function and it ignores the emotions, conscious experience and free will.

The behaviourist approach believes that people, as well as animals, are controlled by their surrounding environment which has a direct impact upon their behaviour and whether they would suffer from mental illness (McLeod, S. 2007). Whereas the biological approach views genes, chromosomes and the nervous system as contributing factors to mental health and the way people behave, this theory believes that people have inherited traits of mental illness which may have adapted through evolution. These perspectives argue whether nature (biological) or nurture (behaviourist) have an influence over life and life decisions which has caused numerous ongoing debates (McLeod, S. 2007).

Though we may not realize it nor want to acknowledge it, Cognitive Psychology is a part of every human 's daily life. Cognitive Psychology is the scientific study of the mind as an information processor. In a simpler definition, it is the study of how our minds interpret and process things that we either are informed of or something we take into thought. Cognitive Psychology is a part of our attention process, language use, our memory for both long and short term, perception, problem solving, creativity, and the way we think. Each of these different features are a part of how we perceive information, think, remember, and use the information we gather. Through this branch of psychology, researchers are able to observe the relationship

The nature- nurture debate has many different case studies, which often questions environmental and hereditary aspects of the nature- nurture debate. A tangent which is focused on in this essay is how the case studies of schizophrenia and IQ, specifically affect twin and adoption studies. This essay will firstly, give a brief outline of the nature-nurture debate and the definitions of twin and adoption studies. Secondly, it will illustrate two main case studies, which are IQ and Schizophrenia studies. Thirdly, will contrast and compare the two and research’s impact on the case studies in regards to nature vs. nurture and finally, will conclude with the impact of the nature-nurture debate and twin and adoption studies.

According to Ronald Comer, biological theorists view abnormal behavior as an illness brought about by malfunctioning parts of the brain. These malfunctioning parts can be brought around by a chemical imbalance as well as brain structure abnormalities. So, they tend to point the problem to the anatomy or the chemistry alone, adopting a purely medical perspective. The brain is made up of millions of tiny connections call synapse. In order for the biological process in the brain to work properly everything must be functioning perfectly. The brain runs on an all or none perspective, meaning if one small neuron isn’t firing properly, (the firing of the neurons is how the brain is charged to function) the neuron will die and stop working. This is the chemical outlook of mental illness, that mental illness could possibly be brought around by the misfiring of neurons, or the complete failure to fire that neuronal death could cause.

Nevertheless, the term “mental disorder” is applied to a set of categories and classifications of abnormal human functioning. Millon (1969) grouped perspectives on mental disorders into four different categories. First, there are biophysical theories, which assume that physiological processes are the primary determining factors of psychopathology. Second, there are intrapsychic theories which assume that psychological factors determine abnormal psychological behavior. Third, there is phenomenological theory which talks about the unique experience and perception of each individual, and how that perception is lived out. Lastly, behavioral theories assume that the process of learning through reinforcement shapes pathology in the individual.

The biomedical model of health takes into account the physical or biological quality of life and is widely used in the Western medicine approach to health (Gurung, 2104). A basic assumption of this model is that the mind and body connection is irrelevant. Many advances in medicine have occured because of the biomedical model of health. In using evidence-based medicine it has been possible to evaluate the results of clinical and pharmaceutical research in order to make strides in medicine (Ashton, 1999). It takes advantage of algorithmic treatment options. Even though this approach may be more difficult for a psychiatrist to utilize when diagnosing and treating a patient, this model has radically shaped psychotherapy research and psychiatric medication (Deacon, 2013). The biomedical approach lends itself more readily to research because of its quantitative nature and it is less subjective than the biopsychosocial approach when measuring emotions and culture.

The chapter discussed nature versus nurture and how even if we have a genetic disposition to something depending on the environment we are in we may not wind up getting that thing for instance adoptees whose mothers had schizophrenia, who grew up in healthy environments only 5.8% were likely to develop schizophrenia meanwhile adoptees who lived in disturbed family environments were 36.8% likely to develop schizophrenia. This indicates that while nature plays a role in the possibility of developing schizophrenia nurture plays a role as

There are several models of abnormality in use today (Comer, 2009) lists “The Biological Model…”, “The Psychodynamic Model…”, The Behavioral Model…”, The Cognitive Model…”, The Humanistic-Existential Model…”, The Sociocultural Model…” (p.33). The biggest contrasts would be the Biological model, and the other models. Comparing the biological model, and the cognitive model will highlight those differences.

Cognitive psychology is the study of mental processes. The American Psychological Association defines cognitive psychology as "The study of higher mental processes such as attention, language use, memory, perception, problem solving, and thinking."[1] Much of the work derived from cognitive psychology has been integrated into various other modern disciplines of psychological study including social psychology, personality psychology, abnormal psychology, developmental psychology, and educational psychology.

How is the nature vs nurture debate related to a consideration of the mental disorder, schizophrenia?

“Cognitive psychology is a modern approach to the study of [processes by which people come to understand the world- such processes as memory, learning, comprehending language, problem solving, and creativity. Cognitive psychology has been influenced by developments in language, computer science, and of course, earlier work in philosophy and psychology” – Hayes (cited by Lundin)
