Discuss the biological approach in psychology. Refer to at least one other approach in your answer. (12 marks) The biological approach focuses on both the physiological and evolutionary aspects which explain human behaviour. The causal level of analysis incorporates physiological explanations‚ such as the effect of nerves and hormones on behaviour. According to biological psychologists‚ behaviour is controlled by the nervous system‚ which consists of the central nervous system (the brain and the

TYPES OF PACEMAKERS The classification of pacemakers into different types is based on the mode of application of the stimulating pulses to the heart. EXTERNAL PACEMAKERS: These are used when the heart block presents itself as an emergency and when it is expected to be present for a short time i.e during critical post operative periods and in patients during cardiac surgery‚ involving the valves or septum. * The pacemaker is placed outside the body. It may be in the form of wrist watch or in

Psychology AS Level Guy Webber The Biological Approach What assumptions do biopsychologists make? Psychologists from the biological approach assume that behaviour and experiences are caused by activity in the nervous system of the body. The things that people think and feel‚ say and do are caused‚ one way or another‚ by electrochemical events occurring within and between the neurones that make up their nervous system‚ particular those in the brain. Many biopsychologists also agree that

Describe circadian rhythms (8marks) Circadian rhythms occur every 24 hours; an example of a circadian rhythm is the sleep-waking cycle. We are diurnal animals who are active during the daytime and asleep at night‚ other animals are nocturnal they are active at night but asleep during the day. The circadian rhythm depends on the interaction of physiological and psychological processes to be tuned into the sleep-waking cycle so energy is provided when needed. As diurnal humans we have a fairly stable

Discuss Biological Treatments for Schizophrenia (24 marks) The vast majority of people who suffer from schizophrenia will receive some form of treatment to try and diminish their symptoms. There are drug therapies that help patients to function as well as possible‚ and were founded in the 1950’s when the drugs were given to hospital patients to try and calm their anxiety before surgery but were also found to relieve the symptoms of schizophrenia and so consequently were used for treatment of

Living with a Pacemaker or Implantable Cardioverter Defibrillator (ICD) With advances in technology‚ pacemakers and ICDs generally last five to seven years or longer (depending on usage and the type of device) and‚ in most cases‚ allow a person to lead a normal life. In addition‚ advances in device circuitry and insulation have reduced the interference risk from machinery‚ such as microwaves‚ which‚ in the past‚ may have altered or otherwise affected these surgically implanted cardiac devices.

This chapter discusses the biological perspective on addiction. When looking at this perspective it is important to understand the biological causes of addiction‚ tolerance and withdrawal. The chapter discusses the different ways drugs can be administered and absorbed. Further it talks about the different ways drugs are metabolised and excreted and how drugs affect the central nervous system. Lastly it examines tolerance and withdrawal as understood from the biological perspective. There are many

Essay ON PAcemaker A pacemaker (or artificial pacemaker‚ is a medical device that uses electrical impulses‚ delivered by electrodes contacting the heart muscles‚ to regulate the beating of the heart. The primary purpose of a pacemaker is to maintain an adequateheart rate‚ either because the heart’s native pacemaker is not fast enough‚ or there is a block in the heart’s electrical conduction system. Modern pacemakers are externally programmable and allow the cardiologist to select the optimum pacing

There are several different explanations for the disorder schizophrenia. One of these explanations is the biological model. This model explains schizophrenia through biological faults‚ for example viral infections and brain abnormalities. Genetic Factors Some psychologists say that schizophrenia can be passed down generations‚ meaning that some people inherit the disorder from their parents. Twin research has consistently shown that identical twins have a greater risk of developing schizophrenia
