Being able to recognize faces is very important for us to distinguish one person from another. A disorder called Prosopagnosia or face blindness, usually caused by damage to the brain, causes people to lose the ability to recognize faces. This disorder is more common than we realize. I found this topic interesting because I think prosopagnosia is a very usual and complicated disorder to understand, so I wanted to know more about facial recognition. The question at hand is how damage to certain parts of the brain affect facial recognition. Benton (1980) examined patients with brain legions and how it affected their ability to recognize faces. In one study, they presented the participants with a test consisting of 3 parts: “(a) matching …show more content…
However, damage to certain parts of the brain can create false memory. Reminger, Glisky, Kaszniak, and Comer (1999) researched how frontal lobe damage can cause false facial recognition. The first study consisted of patients with frontal lobe damage, patients with temporal lobe damage, and the control group. There were four versions of the test: 32, 24, 16, or 8 faces. The participants were presented pictures of faces one at a time. After looking at all the pictures, the participants were presented the faces again and they had to hit the “yes” key if the have seen the face before and the “no” key if they have not. The results showed that all groups did better the smaller the set size was .There was no significant difference in hit rates between the control group and frontal lobe group, but the temporal lobe group did significantly worse compared to the others. However, the Frontal lobe group had a greater false alarm rate compared to the temporal and control group. The Discrimination index (Pr) was used to measure recognition accuracy and the Bias index (Br) was used to measure probability that the participants said “yes” when they were not sure of the

Visual Information Processing

...to express what we see. The brain and eyes work together to help processing information through our vision. The brain stimulates our five senses, such as touch, smell, sight, taste, and hearing however, most stimuli are interpret through the sight. Our eyes allow us to see things, such as objects, shapes, and colors. The brain helps to perceive and interpret what we see. This process is called visual information processing which pertain to person cognitive skills. Our cognitive skills allow us to see things, process it, and interpret it to make sense. By using our eyes we can see things and hold on to memories and tell our children family history. This paper will describe visual information processing and explain two conditions that impair visual information processing. This paper wills also discuss current trends in research of visual information processing and give two scholarly peer reviews on visual information processing. Visual Information Processing The human brain is responsible for to help understand information that see to the brain.. To understand visual information processing one must for know how the brain and eyes work together. The human brain is an important part of our body. The brain helps other parts of the body function properly. Perception must occur and the brain helps to interpret and perceive information by stimulating our five senses, such as taste, smell, sight, and touch. To process information a stimulus is needed to trigger senses in the brain...

Brain and Lobes

...The Brain and Behavior In this paper I will be discussing the contrasting roles of the temporal and frontal lobes on behavior. What types of behaviors the temporal and frontal lobes are responsible for, and finally what can possibly happen if there is any damage within these lobes. According to the Merriam Webster online dictionary, the brain is an “organ of the body in the head that controls functions, movements, sensations, and thoughts.” (Merriam Webster, n.d.) The cerebrum is the largest part of the brain; and is divided into two hemispheres and four different lobes. Each lobe controls many major functions, behaviors, emotions, and feelings that we need and use in our everyday lives. Lobes and What They Control There are four different sections in the brain called lobes, these lobes are called, the frontal lobe, the parietal lobe, the occipital lobe and finally, the temporal lobe. Each of these lobes has different functions that contribute to the many different behaviors of people. The frontal lobe, also called the cerebral cortex is located at the front of the brain right behind the forehead. This lobe is associated with reasoning, higher level cognitive, motor skills, and expressive language. According to K. L. Hartwig, the frontal lobes of the brain “are the seat of emotions and judgments related to sympathy, which is the ability to feel sorrow for someone else's suffering, and empathy, which the ability to understand another's feelings and problems.”...

Visual Information Processing Paper

...Visual Information Processing Paper Laura Nancy Vargas PSYCH/64 December 2, 2013 Holly Berry Perception Paper Humans have a unique and wonderful device in how one sees. The eye and brain work together to turn the world into visual data one’s brain can understand and use. There are some eye conditions that inhibit the sight or the recognition of the shapes one sees. Research continues to overcome these conditions as well as to further understand the biochemical reaction that gives humans the sight and understanding one has of visual data. Included in the paper are some of the latest research methods. Describe Visual Information Processing The way a human eye and brain works together to produce visual data understandable to the brain is through a biochemical reaction to light turned into neural impulses by the brain. The section of the brain dedicated to interpreting vision is the visual cortex. . Light passes through the lens and the vitreous humor and falls on the retina at the back of the eye (J.R. Anderson, 2009, pg. 34). The retina includes the light sensing or photoreceptor cells. These cells change physical shape when exposed to light. The photoreceptor cells are of two kinds; rods and cones. At this point the photochemical process occurs that turns the information of the light, including shapes, texture, color, orientation, and depth, into neural impulses. Rods are the cells that when exposed to less light energy are responsible for less sharp images, the kind...

Visual Artist Research Paper

...the World in Seventy-Two Days. I will now look at each of these people in more detail starting with Chuck Close by writing a bit about his contemporaries. All of the contemporaries of Chuck Close in this research paper are part of the Photorealism Movement. The first contemporary is Ralph Goings who was born in 1928 and his work focused on painting buildings and cars. The next contemporary is Malcolm Morley who was born in 1931 and he would take photographs from places such as magazines and would repaint them. The final contemporary I will be writing about is Robert Bechtle who was born in 1932 and he would paint images from where he lived and the people around him. The next thing I will be looking at is what makes Chuck Close’s style unique and why he is considered to be important. One of the things that makes Close’s style unique is that he very rarely paints a subject’s body and focuses on their face instead. Another thing that makes Close’s style unique is that he has used multiple types of media throughout his career, such as photography and painting. Close also was paralyzed later in his life and now paints using his mouth. Chuck Close is considered to be important because he brought back the art of painting portraits in the 1960’s to now. The next thing this research covers is the people that influenced his work. One person that Chuck Close influenced is Jackson Pollock who was and abstract artist who was born in 1912 and died in 1956. Another person that influenced him...

...THE NERVOUS SYSTEM  The nervous system allows the animal to quickly detect, communicate and co-ordinate information about its external and internal environment so it can make efficient appropriate responses for survival and/or reproduction. The two major parts of our nervous system are the central nervous system (CNS) and peripheral nervous system (PNS). The CNS is made of the brain and spinal cord.   The cranial nerves, spinal nerves and ganglia make up the PNS. The cranial nerves connect to the brain. The cranial and spinal nerves contain the axons (fibres) of sensory and motor nerve cells.   Nerve cells areas are also known as neurons. Neurons are the basic unit of the nervous system. They carry information or impulses as electrical signals from one place to another in the body. There are 3 types of neurons: Sensory Neurons- Sensory neurons carry electrical signals (impulses) from receptors or sense organs to the CNS. Sensory neurons are also called afferent neurons. The cell body of sensory neurons is outside the CNS in ganglia.   Motor Neurons- Motor Neurons Carry Impulses From The CNS To Effector Organs Motor Neurons Are Also Called Efferent Neurons. The Cell Bodies Of Motor Neurons Are Inside The CNS.   Interneurons- These are also called intermediate, relay, or associative neurons. They carry information between sensory and motor neurons. They are found in the CNS.  TOP The Structure of Neurons A Neuron consists of THREE MAIN PARTS:     A. CELL...

What are the things that glue in our knowledge of the world? We are talking about the role of experience in shaping our lives. The rules of learning give us great adaptability. There are three basic types of learning. They are habituation, classical conditioning, and instrumental conditioning. Imagine a worm. When the tide is in, it comes out. It has extensions from its head, getting particles from the outside. So it comes out of its hole to snatch these particles. It has one fear though: seagulls. The worm is delicious to them. They see him and they eat him. The worm has a detection system wired in though. When there is a shadow, he ducks. It is a hard-wired reflex. Sometimes, however, shadows don’t mean a darn, like on a cloudy day. If it doesn’t come out because of the shadows, it will get nothing done and starve to death. Therefore, if the shadows are too frequent, it will ignore them. There...
