Week 2 Assignment
Assignment: Perception
You are not aware of the many brain processes that help create your experiences. For example, the hippocampus, a part of your brain, processes memories of facts and episodes while the amygdale, another part of your brain, processes emotions. Additionally, the thalamus, located on top of the brainstem is the brain’s sensory switchboard because it receives information from all of the senses, except smell. Imagine life without one of or more of these parts of your brain functioning properly.
To further explore the connection between brain structure and thoughts, consider the following scenario:
Car A runs a red light and collides with Car B. Two women witness the collision. One, a mechanic at an auto body repair shop, is able to analyze details of the crash because of her extensive experience repairing damaged vehicles. The other woman had a panic attack because she was involved in a near fatal accident six months prior. Although both witnessed the same collision, each woman’s reaction is very different.
For this Assignment, you explore the brain’s interworking by explaining why two people witnessing the same event have different reactions.
To prepare for this Assignment:
- Two people can experience the same situation yet have dramatically different perceptions of what happened. Review the following scenario:
- You are sitting in a meeting, when two coworkers arrive late. The first apologizes and says, “Sorry, there was a minor fender bender at the intersection, and I had to wait a few minutes to get around it.” A few moments later, the second coworker enters and says, “I’m sorry I’m late, but there was a terrible accident at the intersection. There was a lot of damage. I’ll be surprised if no one was killed!” You realize that both are describing the same accident.
- Review Module 3, “Neural and Hormonal Systems,” to explore the link between biological activity and psychological events.
- Review Module 4, “The Brain,” and focus on what each part of the brain controls. Consider how brain function is related to thoughts, feelings, and behaviors.
- Review the web tutorial, “Neural Messages.” Focus on each function of the nervous system (such as hearing a sound).
Submit by Day 7 a paper of 1–2 pages explaining how two people may have completely different perceptions of the same event. Use this week’s Learning Resources to inform your response. Explain how each witness’s brain structure and neurotransmission is responsible for their different reactions.

How Mind is Responsible for Differences in Perceptions among Individuals
Perceptions are the way people organize and interpret their sensory feelings to achieve a particular meaning (Finkelstein, Matarazzo, & Zimmerman, 2007). Each Individual has his/her unique way of viewing things. Perception often results from the mental way of giving significance to particular stimuli such as color, feeling, shapes, smell, pain, sound, taste and touch. It is from the perception that individual responses to particular situations that can be understood or known. At the center of the perception is the role of the mind, which coordinates all body responses.
Human mind is the manifestation of thought and awareness of the consciousness, perception, emotion and imaginations that take place in the brain (György, 2006). The biggest part of the brain is the cerebrum, which is responsible for intelligence and reasoning. The body organs such as hands, skin and eyes are responsible for detecting a stimulus, which is then transmitted to the brain for interpretation. The brain can interpret a similar stimuli felt by two in two different ways. Individual nerves contain specialist nerves that respond differently to energy that are received. Although the brain works with the aid of the electrical signals send by the neurons, it is also subject to influence from other neurotransmitting substances. In addition, the mind stores information, which can be retrieved and used to interpret current situations. Therefore, minds of two individuals are general in respond to changes in the environment. This provides some implications in which two individuals perceive the world. Two individuals can have different perception of a particular situati…….…………………………………………………………………………………………………….
