Selye was convinced that reactions to stressful situations: a. were general and nonspecific b. differed, depending on the type of stressor that was present c. were stronger when people had other physical illnesses d. differed, depending on the personality characteristics of the individual __A__ 3. The physiological reaction to an environmental threat, in which the autonomic nervous system energizes the body and hormones are released by the endocrine system, is called: a. a fight-or-flight response b. a resistance response c. a generalized anxiety response d. reaction formation ___D_ 4. In the general activation syndrome (GAS), described by Selye, the sympathetic division of the autonomic nervous system first becomes activated during: a. the resistance phase b. the stage of exhaustion c. recovery from the stress d. the alarm reaction __C__ 5. Quinn was driving his car on an icy road when the back end started to skid out of control. His car crossed the centerline, and he could see the headlights of rapidly approaching oncoming traffic.

As a result, this document can fail to accurately represent a culture, producing misleading data. - One major problem for deindividuation theory is that deindividuation can produce increases in pro-social behaviour rather than aggressive behaviour. - Deindividuation can also lead to a freeing of inhibitions rather than aggression - For example: Gergen et al – men and women were placed in either a lit room (control group) or a completely dark room (experimental group) - Participants who did not know each other were told that there are no rules about what they do together. Also told that after the study, they would not interact with each other. - Participants in the lit room – found the experiment a boring experience - Participants in dark room – First 15 minutes, participants in the dark room chatted idly.
Outline and evaluate the body’s response to stress The body responds to stress by releasing chemicals into our blood to give us a boost to do whatever needs to be done to survive, one way to describe what happens is to use Selye’s General Adaptation Syndrome (GAS). Stage 1: Alarm When something is perceived as stressful and the HPA axis and SAM pathways are activated, the body releases stress-related hormones such as adrenaline, the heart rate and blood pressure increases, this is to give us a boost to either run away or face the stressor head-on, (otherwise known as the “fight or flight response”. Stage 2: Resistance If the stressor persists the body’s response carries on, and stress-related hormones continue to be released, and the arousal remains. Stage 3: Exhaustion If the stress persists for a long period of
The human body is designed to know when stress is used and is effecting the body and your body should know how and when to react to it. Everyone thinks that stress is a bad thing but it is also a positive. This is because stress is keeping you alert and will prepare you for any kind of danger. Stress can become dangerous is someone is faced with stress continuously without any kind of relief. Stress becomes very dangerous when they use alcohol, tobacco or drugs to try and relieve the stress.
Cohen found a positive correlation, as stress levels increased so did the likeliness of illness. However Evans et al (1994) says the effects of stress are not always negative and can even enhance the immune system. Evans looked at the effects of stress by studying the activity if one particular antibody- sIgA. He arranged for students to give talks to other students (mild acute stress). These students showed an increase in sIgA whereas during the examination period, which stretched over several weeks, the levels of sIgA decreased.
FAHEEM KHAN GRADE 12 A SUBJECT : L . O TASK TWO ACTIVITY 2 : INVESTIGATION TASK ( HUMAN ) HYPERTENSION DATE : 25 /04 / 2012 DESCRIBE THE LIFE STYLE DISEASE THAT YOU HAVE CHOSEN HYPERTENSION; HBP; BLOOD PRESSURE – HIGH HYPERTENSION IS THE TERM USED TO DESCRIBE HIGH BLOOD PRESSURE. BLOOD PRESSURE IS A MEASUREMENT OF THE FORCE AGAINST THE WALLS OF YOUR ARTERIES AS YOUR HEART PUMPS BLOOD THROUGH YOUR BODY. BLOOD PRESSURE READINGS ARE USUALLY GIVEN AS TWO NUMBERS – FOR EXAMPLE, 120 OVER 80 ( WRITTEN AS 120/80mmHg ). ONE OR BOTH OF THESE NUMBERS CAN BE TOO HIGH.
I believe that what Milgrim did in his experiments were unethical to his naive subjects because he lied to them to get what he wanted, it caused them to have mental break downs when they left the test room, and because he abused the trust people have with scientists. What Milgrim did in his experiments was he would take random people from the town of New Haven and basically say to them that he
When the body detects stress, the SNS is activated which leads to raised heart rate, which leads to higher blood pressure which can lead to Chronic Heart Disease, heart attack, stroke etc. The Beta Blocker is taken then and it acts by reducing activity of adrenaline and noradrenaline and also binds to the receptors of the heart and other areas of the body stimulated by arousal. As a result of blocking these receptors, it is therefore harder to stimulate them and so the heart beat is slowed, and therefore lower blood pressure. A strength of drug treatment is that they are proven to be affective, for example Kahn et al tested 250 participants over 8 weeks, and found that BZs were better than a placebo. The drugs are also very quick and easy to use, and do not require extra effort or stress that could be incurred using other, longer methods of stress management.
The release of dopamine typically induces a sense of aroused euphoria which may last several hours. When we are stressed or under threat, the central nervous system prepares us for physical action by creating particular physiological changes. Amphetamines prompt the brain to initiate this 'fight or flight' response. These changes include, the release of adrenalin and other stress hormones, increased heart rate and blood pressure, and redirected blood flow into the muscles and away from the
