According to psychology professor Yolanda Williams, perception is our ability to perceive and evaluate sensory data. This involves how we respond to a situation with our facts (Williams). Psychology studies behaviour and thought processes (Milnes). Psychology studies behaviour and mental processes, whereas perception is how we react to stimuli. That is our reaction to the situation.
The sensation is another name for perception, and the trend is revaluating information from the world into the brain (Alley Dog). We utilize our senses to notice and distinguish things, which help us absorb information, uncover emotions, and respond to situations.
There are two sorts of perception theories: self-perception and cognitive dissonance. There are various ideas concerning perception. Even if you think perception is only a person's point of view, some illnesses connect to it.
First, the self-perception hypothesis, based on B. F. Skinner's research, holds that people learn about themselves through witnessing their behaviour and the contexts in which it happens. A person who describes "butterflies in the stomach" is one example. We've all felt it, alone (Bem).
The cognitive dissonance theory involves a person having two opposing thoughts. For example, someone who believes sugar is unhealthy for you yet continue to consume it because they feel that not eating sugar will make no difference to their present health. These ideas clash, almost hypocritically. According to Leon Festinger, dissonance generates psychological discomfort, which leads the individual to attempt to keep their thinking consistent. Also, to minimize dissonance, the individual will want to avoid settings that feature that issue (Festinger).
Perception, like other aspects of psychology, is very scientific. Something about the light and our eyes: reflecting light reflects from your face, mirror, and into your eyes. The energy is subsequently converted into neural impulses by your eyes, which your brain analyses and arranges into what you see. Humans can only perceive a small percentage of the electromagnetic spectrum, from gamma to radio waves (Jenkins, Sensation & Perception).
Wavelengths and amplitudes are how our eyes see. Short wavelengths and high frequencies delete blueish hues, whereas long and low frequencies omit reddish colours. The amplitude controls the brightness. Amplitudes are bright or drab colours (Jenkins, Sensation & Perception).
Light enters the pupil and cornea, and then hits the lens, a clear disc behind the pupil. This concentrates light rays into pictures that are projected onto the retina. The retina is the inner surface of the eyeball that includes all of the visual receptor cells. The axon tails form the ropy optic nerve, which travels from the thalamus to the visual cortex in the occipital lobe (Jenkins, Perceiving believes). This gives us a new perspective on the world.
Oliver Sacks, a distinguished physician, lecturer, and author of unique case studies, is admired for his work yet cannot recognize himself in a mirror. A kind of Prosopagnosia limits the capacity to see or identify faces. AKA: facial blindness. He can see his handwriting or a book on a shelf, but not a close buddy in a crowd. His Fusiform Gyrus, considered essential in facial perception, is broken. Many studies demonstrate that the occipital lobe and amygdala play this condition (Jenkins, Sensation & Perception).
Hallucinogen Persisting Perception Problem is another perception disorder. It is a psychological condition, not a medical illness, according to DSM 5. Palinopsia generates recurring visuals after the stimulus has passed. Hallucinogen Persisting Perception detects more distractions or interferences than normal vision. It's natural to notice floaters while staring at something bright. Higher frequencies are experienced by hallucinogen users, interfering with daily living. A person with this disease may have trouble naming colours or distinguishing between them. While reading, the words and letters may move all over the page (Joseph).
Expectations, experiences, feelings, and occasionally cultural conventions all affect perception. The mind, not the brain, is involved here. Expectations allow us to deceive ourselves. Our eyes help us see information, but our reason is the most powerful. Psychological variables determine our perceptual set. Mood, for example, might affect our perspective. A hill may feel harder while walking alone while listening to sad music, but it will feel less steep when walking with a companion while listening to pop or a happy track (Jenkins, Perceiving is Believing).
Another aspect of perception is depth perception. To perceive in three dimensions, the retina only receives two-dimensional pictures. Depth perception aids in determining an object's distance and form. We employ binocular cues, or retinal disparity, which requires two eyes. Rx difference aids with depth perception. You now have four fingers instead of two by seeing beyond your index fingers. Interposition and linear perspective are monocular signals. This includes relative height and size, linear perspective, texture gradient, and interposition (Jenkins, Perceiving believes).
Motion perception determines object speed and direction. Your brain interprets motion as decreasing items retreating and expanding objects arriving. When it comes to action, your brain may easily be deceived. For example, huge things appear to move more slowly than small ones. We need consistency in our world experience to organize objects by form, depth, and motion. No matter the distance, view angle, or movement, perceptual constancy allows us to recognize an item. Even if it varies in color, size, and shape, if we see a green Chihuahua, we know it's a Chihuahua. A person with contradictory ideas could claim it's not a Chihuahua because it's a different color, even if it is (Jenkins, Perceiving is Believing).
Our minds shape most of our perceptions. Our eyes and brain conduct the science, while our minds determine how to interpret the results. Whenever we feel anything, our minds opt to store it for later evaluation.
