Selective Visual Detection

The system consists of the eyes where the information is collected, geniculate lateral nucleus and visual cortex. The visual cortex could be subdivided into the primary visual cortex and the striate cortex. This sensory system is located at the back of a brain parts of which are located in both hemispheres. Recent studies obtained a sufficient amount of information in order to construct the two-stream hypothesis, which describes the ventral and dorsal streams. The ventral stream begins at the primary visual cortex and goes to the inferior temporal cortex. Main functional responsibilities of this area include identification of objects and the emergence of the long-term memory the origins of which are placed in this area (Rauschecker, Josef P and Sophie K. Scott 722). Dorsal stream also begins at the primary visual cortex and ends at the posterior parietal cortex. It is mainly responsible for the body part control required in order to manipulate an object. The research shows that these "what" and "why" systems are not directly related, and the damage in one affect the other only to a certain extent. It could be explained by the fact that that input is transformed differently via action and

Attention is thought to be selective-focused on one subject at a time. Traditionally, it has been assumed that automatic processing is involuntary, it does not require attention, and is relatively fast; whereas, controlled processing is voluntary, does require attention, and is relatively slow. We can conclude from this that the more we repeat a certain material or tasks the more it becomes automatic and effortless to us.

Selective attention is a cognitive process used when reacting to only certain stimuli when multiple occur simultaneously, helping the human brain be productive, focus, and filter out unnecessary information. This phenomenon is explained by the Stroop effect theory. This was studied by Stroop (1935) in the experiment we will be loosely replicating to further increase credibility of the theory. He aimed to explore how cognitive interferences affect the reaction time of a task. In the experiment, participants were asked to to verbally name the color of the ink or the meaning of the word depending on the condition. He began by testing words with congruences, incongruencies, and a neutral control. The congruent words matched the meaning and color, the incongruencies were random and the color did not match meaning, and the neutral control was black ink. By recording the time

Attention is considered to be a core cognitive process, it refers to how people actively process specific information in the environment. Attention refers to how people select from information and stimuli in the environment, facilitating processing of some of the stimuli and inhibiting processing of others. "Everyone knows what attention is, it is the taking possession by the mind in clear and vivid form, of one out of what seem several simultaneously possible objects or trains of thought...It implies withdrawal from some things in order to deal effectively with others, and is a condition which has a real opposite in the confused, dazed, scatterbrained state. “This definition of attention was proposed by psychologist William James (1890). This review will focus on literature that gives explanation to selective attention. Selective attention refers to the process where a person is able to select out of many stimuli and focus on the one they want and ignore other stimuli.

Abrupt appearance of an object within peripheral visual fields are sudden onset distractors (SOD) and they can have effects on attention and reaction times. Attentional capture occurs when a distractor stimulus appears in a field of vision and pulls focus away from the task at hand. This has the effect of increasing reaction times as it diverts a subject’s attention while the brain registers and processes the new information. When the brain is focussed upon a specific task the distractor captures attention and thus can increase reaction time through this visual processing mechanism. This demonstrates automaticity, a reflex which is both not inhibited by increasing cognitive load (load-insensitivity criterion) and not voluntarily controlled (intentionality criterion). The attentional

I think the perceptual filter, media, had the most impact on how we see the world. In this day and age, we have an app for everything and there’s always gossip on every single one of them. In my opinion the campaigns for the US election was the worst. We had to be pick a president for our country and the two did nothing but bash each other ON THE MEDIA. From the media all I got out of the election was I either had to vote for a man who made women out to be victims and had no respect for them or a woman who should have been in prison already and lies so she looks like a good person. It was terrible.

When a specific behavior is practiced, multiple areas of the brain can light up and become active. When that behavior is continually practiced over prolonged periods of time, the coactivation of the two zones signifies a link to be created between the corresponding locations, thus changing the physical structure connecting the regions. Once this structure is established, it itself can influence the neural activity of each specific region of connectivity, due to the messages from connecting regions being able to pass through.

The temporal lobe functions activated from the game are retrieving information, auditory reception, and receptive speech. These are activated when landing on the yellow star spot on the game board and having to listen to the word you are suppose to spell and using speech to answer the question. The basal ganglia and cerebellum are activated in the game by using automatic memorized movements and balance. The basal ganglia and cerebellum are most active when doing the action cards in “The Journey To

Cortical plasticity explains to us that changes in neuronal circulatory methods and information processing has lead us to receiving information by experiencing encountering obstacles (McEwen et al. 2013). The plasticity in the brain is very crucial

The basic function is to measure the ability to learn and remember the location of a target zone using a configuration of distal

During this stage, I am able to concentrate on some stimuli while ignoring others. For example, in this picture you can see that I am working by myself. I am concentrating doing an activity and forgetting about the classmates.

The study written about here’s aim was to look at the development of selective attention by using the cross-model Stroop test. The study used fifteen 4-5 year olds, fifteen 6-7 year olds, fifteen 9-11 and thirty undergraduates to participate in the study. The participants were tested individually in a lab and were told they would play a computer game, the aim of the game was to name to colour that appeared of the computer screen however they were wearing head phones and sometimes they would hear a word that could confuse them. The participants were given multiple trial, the first consisting of 18 rounds that occurred in silent conditions, giving the participants a chance to practice and

While system 2 runs the voluntary parts of our brains. It processes suggestions offered by System 1, makes final decisions and chooses where to allocate our attention. The funny thing about how these system work is that we assume a lot of the things we do are purely conscious decisions made by System 2. In fact, almost everything we consciously decide on is based on automatic reactions and suggestions fed to us by System 1.New research shows it takes one part of the brain to start concentrating and another to be distracted. This discovery could help scientists develop better treatments for attention deficit disorder.
