This essay aims to compare and contrast two of the four models of stress; Hans Selye’s (1907-1982) general adaptation syndrome (GAS) and Mowrer (1939) avoidance model. Firstly, the author will give published definitions of the term stress; the author will then briefly discuss the term stress. This essay will look at the Selye (1956) general adaptation syndrome and Mowrer (1939) avoidance model of stress and then compare and contrast both models.
Chorousos et al. (1988) define stress as “the recognition by the body of a stressor and therefore the state of threatened homeostasis”. Schaffer (2000) defines stress as “the arousal of mind and body in response to demands made on them. And according to Sapolsky (1994 p7) a stressor is anything that throws the body out of homeostatic balance, for example, an illness, loud noise, an injury etc. Cox (1978 p. 180) defines stress as a “complex and dynamic system of transaction between the person and his environment”. Based on the published definitions of stress, the author therefore defines stress as anything that causes the body to be uncomforted. Stress can be caused by several different factors ranging from physical (such as fear of something dangerous) to emotional such as worry over children, job, marriage etc.
The term “Stress” was coined by scientist Hans Selye (1907-1982) in 1936. Selye (1926) defined stress as “the non specific response of the body to any demand for change”. Selye (1926) discovered in several laboratory experiments that animals showed similar symptoms when exposed to severe physical and emotional stimuli i.e. extreme heat or cold, loud disturbing noise, etc. Selye (1935) also noted that patients with different illness showed these same similar biological symptoms ...

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.
In the presence of a chronic stress there is a related physiological response that can ultimately influence the progression of health disorders. Clinically, understanding the cognitive and behavioral causes and responses to stress is essential for public health, education, and intervention. The transactional model of stress and coping attempts to evaluate and understand how a person copes with stressful events. We become stressed when the environmental demands exceed our ability to cope. Whether stress becomes a part of a situation is based on primary appraisal. This concept determines the significance of the stressor to the individual’s life. Then, if there is a perception of threat, the secondary appraisal determines whether the individual has the tools to cope with the stress effectively leading to a positive outcome, or if the demands exceed one’s ability to overcome leading to bad
The phenomenon of stress is presented in our lives more and more strongly. In the media, on the internet or at the doctor, we hear about it constantly. But what exactly is this phenomenon? “A large number of studies during the past several decades have explored relationships among environmental stimuli, psychological processes and organismic responses. Those studies that have investigated the various ways in which environmental changes or the perceived threat of such changes lead organisms to make specific adaptive responses are often subsumed under the rubric of stress research.”( Field, Mccabe, Schneiderman, 1985).
Stress, as defined as a reaction to a stimulus that breaks our physical and mental harmony, is ubiquitous. However, stress has two sides – the bad and the good, in which the latter is mostly overlooked as most people suffer from the affliction of the former.
The purpose of this paper is to define stress and how it effects the body's physiological systems. This paper will include the normal functions and organs involved in the following five physiological systems, cardiovascular, gastrointestinal, respiratory, immune and musculoskeletal. This paper will also include a description of a chronic illness associated with each physiological system and how the illness is affected by stress.

What is Stress actually? Hans Selye, the noted stress researcher, once said, “Stress is a scientific concept which has suffered from the mixed blessing of being too well known and too little understood. Physicians, psychologists, biologists, engineers, and students may each have a different meaning in mind when they talk about stress”. One useful definition of stress is that it is a demand made upon the adaptive capacities of the mind and body.
In today’s society, life is fraught of troubles, deadlines, frustrations and demands. In the lives of many people, stress is so prevalent that it has become a way of life. According to many doctors and researchers stress refers to the response people have when facing circumstances that force them to act, change, or adjust in some way to maintain their footing, or to keep things balanced. Today, there are many important contributors to stress (called stressors) and the effects they cause to the human body and mind. Physical, cognitive and behavioral problems are some of the effects that stressors can contribute to the human body and mind. Stress can lead to financial problems, work problems, and relationship difficulties.
Stress is a different for every individual and culture plays a role in the way an individual deals with it. Stress causes the body to lose its internal balance known as homeostasis. Homeostasis states the ideal levels of the body functions in order to maintain its balance (Gerung, 2014). The passage of time changes what stresses individuals. In ancient times, stressors were physical and considered acute and short-term. Such as considering their protection form invading tribes and looking out for predators. The modern times perceives stressors as chronic and long-term. Although now, stress invades through the death of close friends and family, relationships, habit changes in eating, sleeping, social, and pregnancy. The continuous stressers of
Stress a term used to describe the human response to pressure when faced with challenges or even dangerous situations, resulting in an increase in our energy and alertness, a prolonged exposure to stressful stimuli can lead to harmful effect on health, a functional definition of stress may be hard to establish, the research of stress probably started with Selye Hans (1956) using the term “stress” in his book “the stress of life” referring to stress as the unpleasant environmental events and the physiological reaction toward it, examining the effect of anxious but different physical and emotional stimuli on laboratory animals, suggesting that persistence exposure to stress caused these animals to develop diseases similar to those seen in humans.
Stress is the combination of psychological, physiological, and behavioral reactions that people have in response to events that threaten or challenge them. Stress can be good or bad. Sometimes, stress is helpful, providing people with the extra energy or alertness they need. Stress could give a runner the edge he or she needs to persevere in a marathon, for example. This good kind of stress is called eustress. Unfortunately, stress is often not helpful and can even be harmful when not managed effectively. Stress could make a salesperson buckle under the pressure while trying to make a sales pitch at an important business meeting, for example. Moreover, stress can increase the risk of developing health problems, such as cardiovascular disease and anxiety disorders. This bad kind of stress is called distress, the kind of stress that people usually are referring to when they use the word stress.
Stress is not something to be avoided. Everyone feels stressed from time to time and it depends on people that may feel stress in different ways. Not all stress is bad but it depends on how peoples take it. The words “stress” is something all of us have experienced but it seems that there are many different definitions used by psychologist, medics, management consultants or others. Psychologists describe stress as “demands of life” which pointed out as “stressors” and stress is the cause of the worn out tissue of our body (Meenakshisundaram, 2012, p.101). Stress can be divided into four types which are eustress, acute stress, episodic acute stress and chronic stress (illustrated in Figure 1).
Stress is defined as “any circumstances that threaten or are perceived to threaten one’s well-being and thereby tax one’s coping abilities” (Weiten & Lloyd, 2006, p. 72). Stress is a natural event that exists literally in all areas of one’s life. It can be embedded in the environment, culture, or perception of an event or idea. Stress is a constant burden, and can be detrimental to one’s physical and mental health. However stress can also provide beneficial effects; it can satisfy one’s need for stimulation and challenge, promote personal growth, and can provide an individual with the tools to cope with, and be less affected by tomorrow’s stress (Weiten & Lloyd, 2006, p. 93).
The term “stress” has multiple meanings. As Richard Lazarus stated in his 1966 book “Psycho...
First, stress is defined as an unpleasant state of emotional and physiological arousal that people experience in situations that they perceive as dangerous or threatening to their well being (Patel, 14). Stress is a universal feeling to everyone but the word stress means different things to different people. Some people define stress as events or situations that cause them to feel tension, pressure or negative emotions such as anxiety or anger (Patel, 15). Other people may view stress as a process involving a person’s interpretation and response to a threatening event. In any case, stress has many facets of how one perceives and responds to the certain predicament that is ailing them.
