What is the Effect of Watching Various Emotional Videos on Average Heart Rates?
Introduction
Throughout the body, blood is constantly being pumped during the Circulatory system from the heart to the lungs and body and back to the heart. The heart repeats this process multiple times per minute that varies in accordance to the independent variable (i.e. emotion, sugar intake or level of exertion). As the emotion grows more intense, the body then releases adrenaline and other chemicals to start sweating or palpitating in response to the cause of the emotions (Sakuragi, Sokichi, et al. 2002). Knowing when heart rate levels change and how much it changes is important since it can lead to other circulatory or respiratory functional changes (i.e.

The overall average heart rate when watching the satisfying video was 72.72 bpm, which consisted of five of the six experimental subjects’ lowest average heart rates. This situation was similar to the overall 79.92 bpm heart rate average in response to the fear video that caused two- thirds of the subjects’ average heart rates to increase the most. When watching the excitement video, the fourth subject experienced their lowest heart rate average of 71.51 bpm while the third subject’s heart rate was elevated to an average of 67.50 bpm. After watching the sad video the first subject experienced their highest average heart rate of 114.51 bpm, and these three instances of inconsistent responses to emotional videos contribute to the indirect correlation between video type and average heart rate. Since the p- value of 0.2001316741 is less than 0.05 for the evidence to support the null hypothesis, the evidence indicates that there is no significant difference between the specific populations because of the testing errors in the experiment. Such statistical insignificance depended on two main factors: the changed proximity of the data monitor cube to the heart rate hand grips, and the sharp exhalations of CO2 when the subject laughed or talked which caused abrupt increases in the heart rate data. The theory that the average heart rates would increase in …show more content…
The average heart rate’s bpm had shown variation in response to intensifying emotional videos ranging from highest average for one particular video to lowest average for another particular video. After watching the satisfying video, most of the subjects’ average heart rates were comprised of the lowest average heart rate at 72.72 bpm. In similar response to the fear video, most of the subjects’ average heart rates contributed to highest recorded average heart rate of 79.92 bpm. Despite this, there was still uncertainty about which emotional video the subjects’ average heart rates were supposed to increase more than the other. After having watched the exciting video, one subject’s heart rate was recorded as their lowest average heart rate while another subject’s heart rate was recorded as their highest average heart rate. While watching the sad video did not include a subject’s lowest average heart rate, one subject had experienced their highest average heart rate during this particular emotional video. This was because while although certain stronger emotions spark more difference in people’s heart rates, there are also sub genres of primary emotions that result in unreliable heart rate records (Karim, Kasssam S., and Wendy Berry Mendes 2013). As a result of these average heart rates being inconsistent to the emotional video, the given p- value of 0.2001316741 is
Friedman, B. H. Feelings and the body: The Jamesian perspective on autonomic specificity of emotion(2010). Biological Psychology.
Heart rate variability (HRV) reflects the variations in the intervals between heart beats (R waves) over time. The time between two consecutive R waves is termed the R-R interval; it is measured in milliseconds, and is controlled by the autonomic nervous system 1. HRV is a non-invasive method for interpreting autonomic nervous system modulation and provides information relating to each branch of the autonomic nervous system 2. Analysis of the beat to beat variability provides an insight into the relative contributions of the sympathetic and parasympathetic components of the autonomic nervous system’s control of the heart 34. In healthy individuals it is now widely agreed that under normal resting conditions, a high HRV is an indicator that the parasympathetic pathway is dominant over the sympathetic pathway. Consequentially, a large number of various disease states for example, cardiovascular disease have been linked to a low HRV reflecting increased sympathetic activity at rest 5. Studies have reported that regular practice of physical activity improves ...
In the movie, The Human Experience, Abraham Maslow’s and James Fowler’s beliefs play a major role in describing the three experiences that the characters chose to live out. The characters Cliff, Jeff, Michael, and Matthew join each other on three different encounters to experience life in other people’s shoes. The encounters were homelessness, caring for physically and mentally handicapped children, and visited Ghanaians with HIV AIDS and leprosy. Each character learned lessons and were humbled immensely by their experiences.
The study of cardio physiology was broken up into five distinct parts all centering on the cardiovascular system. The first lab was utilization of the electrocardiogram (ECG). This studied the electrical activities of the heart by placing electrodes on different parts of the skin. This results in a graph on calibrated paper of these activities. These graphs are useful in the diagnosis of heart disease and heart abnormalities. Alongside natural heart abnormalities are those induced by chemical substances. The electrocardiogram is useful in showing how these chemicals adjust the electrical impulses that it induces.
To determine if the intensity of exercise affects the heart rate of a 15-year-old boy. Apparatus - 2 stopwatches - 1 laptop (beep test) - 1 fire glass tape (min. 20 meters) - Chalk to mark 20 meters (start to finish). Method 1) Get beep test ready on laptop from - http://www.youtube.com/watch?v=e0U_yQITBks - 2) Bring five male subjects ready at the starting line to run the beep test. 3) Mark 20 meters on the ground outside on the AstroTurf using a long tape.
AIM: - the aim of this experiment is to find out what the effects of exercise are on the heart rate. And to record these results in various formats. VARIABLES: - * Type of exercise * Duration of exercise * Intensity of exercise * Stage of respiration
Metaphorically, emotional energy begins with what Peterson (2007) calls a “thud” and causes a feeling in the gut, such as anger, excitement, jealousy, or happiness. This feeling, whether it is positive or negative, grows and puts pressure on the heart, hardening it and closing the openness one may have earlier had towards what other people feel or ideas they may have. When the heart hardens, the brain becomes “flat” and causes the ears to become barred from hearing anything besides what is inside the mind. This process, called th...

This experiment is designed to test whether or not gender is a major contributing factor to the recovery heart rate in humans. Most would assume that the male heart rate would be considerably faster in recovery time than that of the female. This experiment furthers that assumption by eliminating uncontrolled variables such as age, build, and health conditions.
Cultural based explanations posit that emotions are acquired via socialisation and recognise that cultural beliefs play an important role since research has indicated cultural variations amongst individualistic (USA) and collectivists (Japan) cultures. Studies have also focused on recognition rates of emotions and in relation to age.
Discuss the "cognition versus biology" debate in the study of emotion. Outline first the cognitive position and then the biological position. Discuss one possible, satisfying resolution to the cognition versus biology debate, using an original example to illustrate this
Emotion is the “feeling” aspect of consciousness that includes physical, behavioral, and subjective (cognitive) elements. Emotion also contains three elements which are physical arousal, a certain behavior that can reveal outer feelings and inner feelings. One key part in the brain, the amygdala which is located within the limbic system on each side of the brain, plays a key role in emotional processing which causes emotions such as fear and pleasure to be involved with the human facial expressions.The common-sense theory of emotion states that an emotion is experienced first, leading to a physical reaction and then to a behavioral reaction.The James-Lange theory states that a stimulus creates a physiological response that then leads to the labeling of the emotion. The Cannon-Bard theory states that the physiological reaction and the emotion both use the thalamus to send sensory information to both the cortex of the brain and the organs of the sympathetic nervous system. The facial feedback hypothesis states that facial expressions provide feedback to the brain about the emotion being expressed on the face, increasing all the emotions. In Schachter and Singer’s cognitive arousal theory, also known as the two-factor theory, states both the physiological arousal and the actual arousal must occur before the emotion itself is experienced, based on cues from the environment. Lastly, in the cognitive-mediational theory
“Some emotional experience is an interpretation and not merely given by our physiological state” (Hutchison, 2015, p.127). Dan shows that his personality is biased against sadness, which could be caused by something that has happened in his earlier years. Hutchison (2015) states, “Dan interprets sadness as a way to regain energy and to reevaluate his needs, which also signals other to provide Dan with support” (p.129). However, with the cultural difference many did not know what Dan’s interpretation of sadness was because his fellow classmates have a different meaning of sadness. So, physiological theory shows within different cultures, each emotion are organized around many different affective
The Pursuit of Happyness is a film, based on a true story, depicting the life of a black man who lives in the borderline of the middle class, before falling deeper into poverty while trying to support his motherless child. Chris Gardner and his son Christopher, portrayed by actor Will Smith and his own son Jayden, depict how the lower class lived in the 1980’s, and explored the hardships many Americans faced, such as homelessness, the job market, the breaking apart of a family, and supporting a family while living in poverty. The Pursuit of Happyness, a real life film directed by Gabriele Muccino, tells the story of a man and his family living in poverty, and how Chris Gardner climbed out of poverty through hard-work and determination, while showcasing issues that are still relevant even today.
To conclude, researches propose a number of theories that experience human emotions. The James-Lange theory of emotion and the Cannon-Bard theory of emotion belong to one physiological category of theories. However, chosen theories differ greatly from each other. While the James-Lange theory affirms that different physiological states respond to various experiences of emotion, the Cannon-Bard theory claims that humans react to an inducement and experience that is related to the emotion at that time. Both theories have individuals that criticize them and it is up to the individual to decide which one to
