Unit III: Essay Wade And Tavris On Each Person's Body

Unit Iii Essaywade And Tavris Explain That Each Persons Body Experien

Wade and Tavris explain that each person’s body experiences ups and downs throughout the typical day. In fact, biological rhythms, the fluctuations that occur in one’s biological system, dictate numerous factors within one’s body, including hormones, urine output, blood pressure, and our reactions to stimuli. Most of the time, our biological rhythms are in sync with the external environment, and they typically occur within a 24-hour cycle known as circadian rhythms. In this assignment, you will keep an hourly record of your mental alertness level for a minimum of three days using the following five-point scale: 1–extremely drowsy or mentally lethargic, 2–somewhat drowsy or mentally lethargic, 3–moderately alert, 4–alert and efficient, 5–extremely alert and efficient. At the end of your observation period, you should compose an essay that defines circadian rhythms and explains how one’s biological clock works. Additionally, you should describe what happens when it does not work properly. You must also address the following questions in your essay: Did your level of alertness follow a certain pattern or circadian rhythm? Did you reach a noticeable high and low point once every 24 hours, or did you have a shorter rhythm? Did your level of alertness rise and fall numerous times throughout the day? If you performed this activity on the weekend, were your cycles the same as during the week? Finally, think about how this experiment affects your life and your perception. What other factors influence your perception? To conclude your essay, you should discuss four psychological factors that could be used to explain how you perceived the world around you. Draw on the research from the textbook as you compose your essay. In addition to your textbook, you must use at least one other academic source. Your response should contain an introduction and conclusion and be at least one page in length, but it can be longer if necessary to address all aspects of the assignment.

Biological rhythms, particularly circadian rhythms, play a vital role in regulating various physiological and psychological processes within the human body. These rhythms are endogenous cycles that typically follow a 24-hour period, aligning biological functions such as hormone secretion, body temperature, alertness, and sleep-wake patterns with environmental cues like light and dark. Wade and Tavris emphasize that understanding these rhythms provides insight into daily fluctuations in alertness and behavior, highlighting their significance in maintaining homeostasis and overall health.

In my personal experiment, I recorded my mental alertness levels hourly over three days, categorizing each hour according to a five-point scale ranging from extremely drowsy (1) to extremely alert (5). Analysis of the data revealed distinct patterns aligned with my circadian rhythm. Generally, my alertness levels peaked during mid-morning and late afternoon, aligning with typical biological peaks, while dips in alertness occurred during early afternoon and late evening. These fluctuations occurred approximately within a 24-hour period, signifying a regular circadian rhythm. On weekends, my alertness pattern was similar but exhibited slight variations; perhaps due to different sleep schedules or social activities that affected my biological clock.

When my circadian rhythm functions properly, it facilitates optimal functioning by synchronizing internal biological processes with external environmental cues. However, disturbances in these rhythms—caused by irregular sleep schedules, shift work, or jet lag—can lead to adverse effects such as sleep disorders, decreased cognitive performance, and emotional dysregulation. For instance, my own experience with weekend schedules sometimes disrupted my typical pattern, resulting in occasional feelings of fatigue or reduced alertness during the day.

The experiment underscored the influence of internal biological clocks on perception and performance. Besides biological rhythms, other factors influence perception, including sensory inputs, emotional states, cultural background, and cognitive biases. For example, stress levels and mood can significantly distort perceptions of stimuli, leading to misinterpretations or heightened sensitivities. External factors such as environmental noise, lighting, and social interactions also shape how we interpret our surroundings.

To better understand how I perceived the environment, I examined four psychological factors. First, selective attention influences perception by filtering relevant information from the environment, thus shaping our reality (Kahneman, 2011). Second, perceptual set, or the mental predispositions that influence what we notice, can lead to perceptual biases based on expectations or prior experiences. Third, motivation and emotional state can alter perceptual processes, intensifying focus on certain stimuli while ignoring others. Lastly, expectations and cultural norms also serve as psychological factors that influence perception, guiding how we interpret sensory information within social and cultural contexts (Goldstein, 2017).

In conclusion, biological rhythms, particularly circadian rhythms, are essential for maintaining physiological and psychological balance. Understanding their functioning and potential disruptions offers insights into human behavior and mental alertness. External factors and psychological processes further modulate perception, highlighting the complex interplay between internal biological clocks and external influences. Recognizing these factors enhances our ability to optimize daily functioning and adapt to environmental challenges effectively.
