Question

Objective: Understand how stress is positive and negative and relates to aggression and emotions. A bell-shaped curve can be given to describe stress and performance of simple tasks. A specific level of stress can peak performance. However, too low or high amounts of stress decreases the performance of certain tasks. If the task is more complex, lower amounts of stress increases performance. Vice versa, if the task is simpler, higher amounts of stress can increase performance. (Yerkes-Dodson, 1908) In your own life, give examples of peak performance of a simple task (with high stress), medium task (with average stress), and difficult task (with low stress). Additionally, describe how your brain would relieve itself of the high stress through neurochemicals. Read Chapter 14 in your textbook. Discovering Behavioral Neuroscience: An Introduction to Biological Psychology by Laura Freberg Discuss how stress is positive and negative.

Answer 1

Stress can positively affect performance up to an optimal stress level, known as eustress, but beyond that point, it becomes detrimental, causing distress. The brain counteracts high stress levels through the release of neurochemicals such as endorphins and serotonin, promoting relaxation and well-being.

Step-by-step explanation:

Understanding Stress and Performance

Stress affects performance in complex ways. When stress increases, so does performance, up to a point; this positive aspect of stress is known as eustress. For simple tasks, higher stress levels might enhance performance, enabling an individual to feel energized and focused. However, an optimal level of stress exists where performance peaks. Beyond this peak, excessive stress, or distress, begins to impair performance and can lead to burnout, fatigue, and health problems. A practical example of optimal stress might involve an athlete who experiences stress before a game, leading to heightened concentration and improved performance.

Moving towards how the brain relieves high stress, neurochemicals such as endorphins and neurotransmitters like serotonin are released in response to stress. These chemicals help to alleviate stress by inducing relaxation and feelings of well-being, essentially counteracting the negative aspects of stress. Chronic stress, however, may disrupt this balance, leading to issues such as chronic anxiety or depression.

Furthermore, stress has a two-fold nature where it can be a motivator, pushing us to perform better or act in our best interests, yet it also poses significant risks to our health if it becomes long-term and unmanageable. Managing stress effectively is essential for optimal health and performance.
