reactions. Many people wonder why this still fascinates psychologists. Part of the answer is the effect taps into the essential operations of cognition, which helps us figure out how the brain works. In order to counter this effect, you must have good eyes and a very keen perception. Along with that, you must be very good at being able to focus on a certain thing, and pay attention to detail. If you can't complete these tasks, you…

of vision at which perception can become impaired. Cortical (or cerebral) visual impairment (CVI) refers to any impairment or loss of vision brought about by damage to the brain or the central nervous system, rather than physical problems with the eye itself (ocular impairment); therefore, children and other individuals with CVI do not appear to have any cause for visual impairment when examined physically (Palmer, 2003). Historically, CVI has also been referred to…

The eye is one of the significant special sensory organs that is responsible for vision. Through observation, we handled a cow’s eye and discerned our findings to our knowledge of a human’s eye. A cow’s eye has similarities, such as the overall layers of the eye like the sclera, choroid, and retina layer, to that of a human’s eye. Also the structures and organs contained within these layers. Also, we discovered many other anatomical structures that are much the same to a human's eye during the…

nature in it's best forms and that's precisely what she did. Taking a look back at the historical value of the painting, the techniques she used gave a greater perception of abstract reality. By gracefully placing each stroke of paint it allows the eye to feel emotion from up-close and even more from afar. Using a 74 by 110 sized canvas, Lazzari formed layers upon layers of acrylic paint to transform what appears to be a flower at full bloom, the peak of its life. Although it is uncertain…

handles light. As I get to the path light takes as it enters our eyes I will point out four mechanisms that have to function in order for us to see. Each of our eyeballs have six muscles that attach them to our skull. Four of these muscles pull straight and are called rectus muscles. Two of these muscles pull on an angle and are called oblique muscles. The first mechanism is the coordination of these muscles (both eyes) so that our eyes move together. As we open our eyelids (provides protection…

happened: As Marcus and I parted ways, we walked the same pace. We approached our respective doors, stopped, turned, and shared a look. I looked away and put my hand on the door handle. There does not seem to be a lock. I slowly turned the handle, both eyes closed, expecting something to shoot me. Surprisingly enough, I managed to fully open the door, and didn’t find a mindless, Dauntless soldier pointing a gun at me. I stepped inside and looked around. The room is average-sized, and the same…

eased the sheets down to expose her shoulders, Isla took a slow breath in, confused by the deep voice pressed tightly against her ear. Melatonin and adrenaline both rushed through her veins, causing the woman to jolt in the very next instant. Green eyes flashed open, a startled grunt trembled beneath the grip of his heavy hand and all she could do was react on instinct as her mind struggled to…

Fear. What is fear? To some fear is nothing more than an emotion that we feel whe we feel unsecure about something. To others it's a whole different story. Imagine having everything in the world that you ever wanted, and in the blink of an eye it's all gone. One can never get over the feeling of loosing someone special in they're life. To know that the person that gave you everything is no longer around to help you continue in life. This is my fear, to lose more people that mean so much to me.…

are the successions of ideas,images,sensations and emotions that occurs in the mind involuntarily during our certain stages of sleep.”oneirology” is the term for the scientific study of dreams. Dreams majorly occur in the REM i.e., the rapid- eye movement stage of sleep(when our brain activity is high and resembles the state of being awake) The length of a dream varies i.e., they can last for few seconds, minutes or even for a duration of twenty-thirty minutes, approximately. An average…

person’s eye socket. Thus theoretically making an artificial retina in the process of making the eyeball. This would have to take the creation of artificial photoreceptors as well that could connect to neurons in the brain to create the image for the blind person to see. The key component in the blind person gaining sight is the creation of artificial photoreceptors because they detect light. Photoreceptors convert information into chemical signals that stimulate neurons that process movement,…
