The sweat glands most likely to such hormones are those in the palms and armpit. Most people shake when they’re scared because of the flight of fight response engraved in our genetic codes. Humans naturally have the response to fear or danger because it prompts us to take action when there in danger. Flight or fight is triggered by an increase of adrenaline which quickens the heartbeat, alerts our sense and makes us shake. Sometimes people are scared of the dark is because they feel threatened of what can be in the darkness since not everything is clearly identified in the dark compared to daytime light. It’s just fear of what could be there what might jump out. And they’re not sure how they’ll handle the situation if something does come out and scare them. In a fight or flight situation you body does a number of things automatically so it’s ready for quick action or quick escape. Your heart rate increases to pump more blood to your muscles and the brain. Sometimes it also occurs when there seems nothing to be frightened about. When you feel scared but there is no clear reason why then that is called anxiety. Other feelings that come with this are tightness in your chest, a bellyache, dizziness, and a sense that something wrong is going to happen. When scared your brain activity can be relaxed by mediation and mindfulness which can tame the amygdale, an area of the brain which is the hub of fear of memory. Ekman discovered that experienced were less likely to be shocked, flustered, surprised or as angry as other people. Flanagan believes that if the findings of the studies can be confirmed they can be a major important. Stages of fear is at first people try to avoid a threat in the first place. Then they exaggerate or emotional fear deals with an individual “recalling past fears or occurs and injecting them into a current situation. The controlling variable in this experience is how many people I am going to survey, the dependent variable is how people respond to the survey because I don not control what they are going to respond. In addition the independent variable is what type of question I’m going to ask. [pic] Purpose: Questions that we’ll be in my mind throughout the experiment our: How is fear measured' How do we experience fear' What are the stages of fear' What is fear' Can fear be triggered by past experience' How does fear start' When facing a fear do people have certain habits we do such as shaking, sweating, and etc.' The older you are This experiment is relevant to research because scientist can see how the human mind works and how something can trigger fears to age group. Hypothesis: Based on the information background our hypothesis is that all the age groups have different fears based n their age. As for teens it is hypothesized that they will be worried about their social life and acceptance from others. For adults they are probably be scared of losing someone special such as a family member. In elderly people it is hypothesized that they are going to be scared of getting a disease such as cancer or end up dead leaving their family members behind. The predictions can be testable by getting different age groups and seeing what they are fearful the most. Citation: 1. Andrew Olson, Ph.D., Science Buddies Last edit date: 20 2.
