The perceptual process can be described in seven basic steps, plus knowledge.

  • In your own words, briefly describe each step and knowledge.
  • Consider the flow of information. At what point in the process does sensation occur? Is there a distinct and identifiable point where sensation ends and perception begins? Is the point between sensation and perception located at the same place for all people? Explain.
  • Discuss the interaction during this process. For example, how can perception alter sensation? How do you think attention and interest factor into this process?                                                ***make sure to cite your sources in your work and provide references for those citations utilizing APA format.*** no plagerism and respond to two student responses in 4-5 sentences

Perception is the process by which people become aware of objects and events in the outer environment. Stimulation, organization, interpretation-evaluation, memory, and recall are the five stages of perception. People who researched perception did so because they were curious about themselves and the world, not because they were trying to solve a problem. ( Goldstein, E. B., & Brockmole, J.)(2016). (pg5)

The process begins with a stimulus in the environment, light is reflected and focused, the Receptor process, Neural processing, perception, recognition, action.

These seven processes, plus “knowledge” within a person’s brain, outline the major events that occur between the time a person looks at a stimulus in the environment (in this case, a tree) and perceives, acknowledges, and acts on it. (McCartney, 1970) (pg5)

· (Step 1). It is called distal because it is “distant”—out there in the environment.

· (Step 2). The reflection of light from the tree introduces one of the central principles of perception, the principle of transformation, which states that stimuli and re­ responses created by stimuli are transformed, or changed, between the distal stimulus and perception.

· (pg22-23)

· Step 3 of the perceptual process. Receptor processes include transduction (the transformation of light energy into electrical energy) and the shaping of perception by the properties of visual pigments in the receptor’s outer segments. The result is an electrical representation of the tree

· Step 4 of the perceptual process. Neural processing involves interactions between the electrical signals traveling in networks of neurons early in the system, in the retina; later, on the pathway to the brain; and finally, within the brain.

· The person perceives the tree (Step 5) and recognizes it

· (Step 6). We can distinguish between perception, which is conscious awareness of the tree, and recognition, which is placing an object in a category, such as “tree,” that gives it meaning, by considering the case of Dr. P., a patient described by neurologist Oliver Sacks (1985).

· The final behavioral response is action (Step 7), which involves motor activities. For example, the person might decide to walk toward the tree, have a picnic under it, or climb it. (Cengage, 2015), (pg. 21-24)

Sensation and perception are two distinct but closely connected processes. Our sensory receptors provide us with information about the physical world, and perception is the process through which the brain picks, organizes, and interprets this information. In other words, the physiological basis of perception is the senses. Because each person’s brain interprets stimuli differently based on their learning, memory, emotions, and expectations, perception of the same senses might change from person to person. The chemical changes in the cells that line the back of the eye are caused by the light that enters the eye. The central nervous system receives messages from these cells in the form of action potentials. The way sensory information is organized, analyzed, and consciously experienced is referred to as perception. Bottom-up and top-down processes are both involved in perception. Perception begins when the brain accepts incoming information. It does not always imply a definite and obvious point where feeling finishes and perception begins, nor does it imply that sensation and perception occur in the same location for everyone. (Psychology Press, 2008) (pg. 8)

My question is how can perception affect people’s behavior if every individual perceives the situation differently?
