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

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.

The Circadian rhythm is a daily cycle of biological activity based on a 24-hour period and influenced by regular variations in the environment‚ such as the alternation of night and day. Circadian rhythms include sleeping and waking in animals and flowers closing and opening. The 24-hour sleep–waking cycle is a good example of a circadian rhythm because it clearly illustrates that circadian rhythms depend on an interaction of physiological and psychological processes. Our fairly consistent sleep pattern

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

Pacemaker The human heart is an essential organ of the human body. Its sole purpose is to supply the body with oxygen by pumping blood through a complex system of veins and arteries. However‚ it is often common for the human heart to suffer from various heart conditions‚ such as a heart block‚ slow heart beat‚ heart attack or heart failure. Such heart conditions can lead to weakness‚ fainting‚ shortness of breath‚ or even possibly death. These can usually be treated with medication but in cases

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

CHAPTER 1 Basic principles of pacing Malcolm Kirk The aim of this chapter is to give sufficient background and information about cardiac pacemakers to allow interpretation of electrocardiograms (ECGs) and telemetry strips of normal pacemaker behavior. For more in-depth information‚ such as would be necessary for programming pacemakers‚ a standard pacing text should be consulted. Several of these are listed in the bibliography. Most italicized terms are defined in the glossary at the end of the chapter

A pacemaker is a small computer that sends electrical signals to the heart and helps your heart beat normally. A pacemaker also stores information about your heart rhythms. You may need pacemaker implantation if you: • Have a slow heartbeat (bradycardia). • Faint (syncope).
