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. (pg22-24)
· 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?

Sensation occurs at the beginning of a sensory system, and perception involves interpretation and memory that surrounds the brain (Goldstein & Brockmole, 2016). There are basically seven steps to perceptual process: Stimulus in the environment, light is reflected, receptor process, neural processing, perception, recognition and then action (Goldstein & Brockmole, 2016). Sensation activates our senses, and perception follows sensation, and is the understanding of the sensations (https://explorable.com>sensations-and-perception).
Perception always leads to action, and is constantly changing, for example, if I constantly move my body and eye close to a rose bush, then I will continue to have new images or transformations (Goldstein & Brockmole, 2016). As long as one has the ability to to touch, taste, or feel pain, sensation and perception exists, although our perceptions are built from sensations, but not all sensations result in perception, although they both work together, we don't receive stimuli that remain relatively constant over prolonged periods of time, for example, if I walked into a room and heard a clock ticking, after while, after I start talking on my phone, I would no longer hear the ticking of the clock, this is known as sensory adaption ( https://course.lumenlearning.com ).
Perceptions helps us to understand our world, but it can also be faulty, because it can allow to think things that are not true. There are also things such as beliefs, values, prejudices, culture, and life experiences, that affects perception, an there are things such as attention and motivation, that affects sensation ( https://course.lumenlearning.com ).

Introduction to Sensation and Perception
Try this. Stop focusing on the computer screen and pay attention to any of the other things that are happening right now. Do you hear any noises that you hadn't heard before? Do you hear birds singing, car sounds, airplanes, or the sound of your breathing? There are stimuli around us all the time, and we are always selecting, consciously or unconsciously, what to pay attention to or what to prioritize for processing. However, remember that we can only attend to stimuli that we have the ability to process. We have to possess the proper body parts and specially designed receptors to be able to receive the stimuli. Not having the proper body parts is like trying to catch a fish for dinner without a net or a hook and bait. Sensory processing is like fishing for food—if we do not have appropriate tools, we cannot catch a fish. As you probably know, each sensory modality has specific hooks or receptors that enable us to detect stimuli. For example, our eyes have photoreceptors, and our ears have auditory receptors called hair cells. These receptors are a key component because they transduce physical and chemical stimuli, which means that they change the stimuli into electrical currents so the brain can process the information. If there is no problem with receiving and transducing a stimulus, that stimulus (which is now represented by electrical impulses) must be transmitted and processed throughout the brain. It is in the brain, between primary sensory and higher-level processing, that perception occurs. Recognition and categorization are part of perception, and this is where the perspectives and views of human beings significantly diverge. People significantly diverge in their perceptual processes.
