sensation and perception

Post Question 3\’ PSYC 1710 General Psychology Post Question 3 Chapter 3 – Sensation and Perception Use what you read about sensation and perception in your text, as well as the definition of sound, to answer the following question: “If a tree falls in the forest and no one is there to hear it, does it make a sound?” Your post will be graded on the persuasiveness and originality of your argument (use evidence from the text), as well as the clarity and accuracy of your response (as always, refer to the Psychology Post Rubric for details on how to get a perfect score on your post response). Note: Do NOT use other sources besides your textbook for this post. Notice:Sensation and Perception INSTRUCTOR’S SYNOPSIS This chapter explains how our senses work from a physiological point of view. There are a couple things I would like you to pay attention to as you read the chapter. First, make a note of the seven physical senses, keeping in mind the fact that extra sensory perception (e.s.p.) is not a physical sense. Notice that, besides the five basic senses we usually think about, we also have kinesthetic and vestibular senses, which help us keep our balance. Also, think about the fact that, although our sense organs can be found in various places on the body, the raw data of sensory experience is sent to the brain where it is sorted out. This is how perceptions are formed. Each sensory experience produces a different type of perception, for example, our sense of touch can produce the perception of pain, whereas our sense of smell can produce the perception of certain odors, etc. However, the process by which our senses produce their respective perceptions is very similar. Each sense starts with some form of energy, which is picked up by certain sensory receptors located in the organ (eye, ear, tongue, etc.). The sensory neurons send the signal to the part of the brain responsible for processing the particular form of information (for example, the occipital lobe processes visual information – for a review, see Chapter 2). Finally the association cortex combines incoming messages from all the senses, along with past experiences, to create a meaningful impression (a perception).
