The Cognitive-Behavioural Aetiology of Schizophrenia
The case study suggests that the most likely principal diagnosis of Molly’s mental disorder is schizophrenia, as evidenced by the presence of its main symptoms. The cognitive-behavioural model proposes that schizophrenia develops from the presence of distorted information processing, as well as from maladaptive learning, which lead to the presence of the psychotic symptoms. This essay examines the aetiology of schizophrenia based on the cognitive-behavioural model: Beck and Rector’s cognitive theory, the five-factor theory of hallucinations, and the stress-vulnerability model. It is followed by critical evaluations of each theory.
Beck and Rector’s cognitive theory indicated that schizophrenia …show more content…

Egocentric bias suggests that individuals have an excessive tendency to relate personal experiences to irrelevant events. Extreme externalizing happens when individuals favour explanations of their experiences using unlikely/impossible attributions. Clinical research supports this interpretation, by which individuals with paranoid delusions favour external stimuli that are socially threatening (Bentall & Kaney, 1989), especially when they are emotionally significant (Kinderman, 1994). In terms of disorganisations, Beck and Rector (2005) indicated that disorganised behaviours occur, not only due to neurocognitive impairment, but also the paucity of their cognitive resources, which leads to the difficulty of maintaining and adhering to the rules of …show more content…

A study revealed that there are interplays between the level of stress and vulnerability based upon cellular functioning, and that there are subsequent consequences for the human brain if these conditions are present (Goh & Agius, 2010). This model expands the idea on how individuals process and react towards biological and environmental stressors in different ways.
Additionally, this model integrates several factors that are associated with the disease, not only genetic and biological factors but also the contribution of social learning. Regardless of the elaboration of various factors, this model fails to explain how being vulnerable towards the stressor could lead to the onset of positive symptoms. In other words, there is no clear link established between the vulnerability and the symptoms.
To conclude, the cognitive-behavioural model proposes that schizophrenia originates from the dysfunctional beliefs/attitudes and maladaptive learning. As a strength, the cognitive-behavioural model gives rise to the development of treatment that focuses on challenging and replacing distorted thoughts and dysfunctional behaviours, which is also known as “reality testing”. However, this model does not capture causal relationships with the biological model, which makes it difficult to establish the true link between

It is hard to comprehend how and why people lose their sanity and become mad. I will address how the mind’s struggles caused by individual genes, stress and social-cultural influence affect the lives of Naomi, a 24-year-old college student with schizophrenia and Eric, a 27-year-old classical musician with severe depression.

Mental illnesses are diseases that plague a being’s mind and corrupts one’s thoughts and feelings. Schizophrenia is one of the many disastrous illnesses that consume one’s life, is known as a real disease that deserves much attention. Experts believe that what causes the illness is a defect in the gene’s of the brain, and little signs of schizophrenia are shown until about one’s early adult years. Some effects of schizophrenia can either be negative or positive, but even if the effects could be either one, people should still be aware that there is something puzzling and alarming happening in the mind of a schizophrenic patient.

Paranoid Schizophrenia Essay
531 Words | 2 Pages
Coined by Eugen Bleuler in 1950, the term ‘Schizophrenia’ refers to a group of mental disorders with heterogeneous outcomes. The most prevalent subtype of schizophrenia is the paranoid subtype. Typically, this disorder is characterized by psychosis, in which the patient suffers from altered perceptions of reality. According to the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM – V), the typical subtypes – paranoid, catatonic and disorganized, among others have been eliminated, although the general definition of the disorder remains unchanged. These changes were made due to the clinically diverse prognosis, pathophysiology and etiology of the disorder, which add to its heterogeneity1, 2. In addition, sex of the patient and age of onset of the disorder also contribute to schizophrenia’s diverse effects. The age of onset and sex of the patient heavily influence the demographics and course of paranoid schizophrenia, and in turn are also affected by the patients ethnicity and any premorbid conditions the patient may have suffered1, 3...

The Positive Effects Of Stress: Portrait Of A Killer
873 Words | 2 Pages
To a great extent, stress can be a helpful response, especially for prehistoric humans. During this era, our species needed to react quickly to outside stimuli through a response of “fight or flight”. Through stress, certain hormones are released to help the individual resist the stressor, which may have meant running away from a natural predator. Thus, stress is a positive response that ensures the survival of the species. However, stress over a prolonged period of time causes exhaustion in the individual. Consequently, although stress can be helpful for individuals today, many often experience chronic stress, inflicting varying degrees of damage to their bodies.

Essay On Assessing Schizophrenia
967 Words | 2 Pages
It is not until the Church’s power begins to fade that science could rise to the forefront for the understanding and treatment of disorders. However, science’s reasoning for schizophrenia failed sometimes too. For instance, an explanation of schizophrenia that developed in the 1900’s by Freud believed that schizophrenia evolves from conditions that are caused by a world that is exceedingly strident towards individuals either by parents that have been unnurturing to their children or if they have experienced a trauma. However, in 1948 Frieda Fromm-Reichmann expanded on Freud’s ...

The Origins of Schizophrenia
2420 Words | 5 Pages
Schizophrenia is a behavioural disorder that affects both men and woman. It involves a difficulty in telling the different between real and imagined experiences. The disorder usually sees its onset in teen years or young adulthood. It is often referred to as a type of split personality or multiple personality disorder. Oftentimes people with this condition find themselves socially isolated mainly because people with this condition find it difficult to make normal social responses and have generally disorganized minds. The irritability caused by living with a mind that feels confused much of the time often causes feelings of depression, anxiety and sometimes suicidal thoughts. With treatment many people manage to function well with this affliction, however others are find it difficult and this leads to many other social problems. In this essay I hope to explore some first person accounts of living and dealing with schizophrenia, as well examining some popular texts about culture and scholarly but non medical texts that look at schizophrenia. Such a complex illness and its patients have become the study and focus of many different disciplines over the years so this will allow me to pull information from other non medical disciplines, giving a more ‘real-life’ account of the condition.

Should this be reconsidered as evidence shows that anomalous perception, deviation from what is considered standard, is also exhibited in the normal population? Consequently, conflicting research evidence shows varying differences in whether or not cognitive biases are necessary in the presence of delusions. Which models should scientists, psychologists, and practitioners be referring to, with a wide array of opposing views and findings? Do cognitions give rise to delusions, or do delusions bring about increased levels in

The Relationship Between the Transactional Model, and the General Adaptation Syndrome
1591 Words | 4 Pages
The term ‘stress’ was generally thought to have been a concept created by Robert Hooke in the 17th century. He worked on the design of physical structures, such as bridges; his concept of stress came from how much pressure a structure could withstand. However, Lazarus (1993) pointed out that the term ‘stress’ has been used as far back as the 14th century, when it meant hardship or adversity. Back then it referred to the external stressor, such as the death of a spouse or financial worry; in the 20th century, there are many different schools of thought on this area. Hans Selye (1956), brought together the work of Cannon and Bernard and devised a comprehensive system of physiological stress; which he termed the ‘General Adaptation Syndrome’, and is a 3-stage process. He theorised that a certain level of stress called ‘eustress’ (Cox, 1978) could actually be beneficial to our overall performance. Later In 1976, Cox & Mackay devised another model called the ‘Transactional model’. This model takes into account the individual differences in the perception of the amount of stress experienced by the person. The main difference between these two models is that Selye’s model only accounts for the physiological side of stress, whereas Cox’s model takes into account both the physiological and psychological aspects of stress. Therefore, both models will have slight similarities and differences in their explanation for how stress occurs in individuals, which is the main focus of this essay.
