The Stroop Effect On The Brain

756 Words4 Pages

After recently suffering from a severe concussion, I became more interested in how the brain functions and processes different things. During that time, I had to take multiple concussion tests in which the Stroop Test was included. At the time, I had no clue what this scientific phenomenon was. Later, my Uncle had also suffered from a concussion and had to take the same tests as I did. This led me to wonder, does age affect your results when completing a Stroop task? The Stroop effect is a phenomenon that demonstrates how the brain processes words and colors differently. According to professors at the University of Michigan, "The Stroop effect (sometimes called the Stroop test) is an outcome of our mental (attentional) vitality and flexibility". …show more content…

The brain is one of the most complex organs in the body and it engages in a complex process that allows it to save and recall information. This process begins with the encoding or registration of information and then continues with processing and combining of received information or stimulus. Interference comes into play when you try to recall this processed information. In response to some prompt for use, in this case the Stroop test, the brain searches form some recollection of the stored information. Trying to access that information becomes difficult and interference …show more content…

In the eye, the cornea is entry point for light. In simple terms, the cornea is the transparent tissue at the front of the eye that functions as the window through which all light has to pass through on its way to forming visual perception. The reception of a clear image is dependent on the integrity of the corneal surface. However, with age, the lens is subject to cataracts and presbyopia in addition to other damage. This damage to the surface of the eye effects how people see and could potentially slow their reaction time to what they are seeing. So, a persons eyesight could potentially effect their results when challenged with a Stroop task. Overall, the Stroop effect is a very complex theory that is still being studied today and is very important to understand as it relates to the functions of the brain and eyes and is used as an important measurement or when testing for

When reading Stereo Sue by Oliver Sack in 2006, I realized how important our vision is in multiple ways. The memory of a close friend that passed a few years ago continued to come to mind. My friend named Bill Vickery lost his vision after a surgery on his optic nerve where the nerve was beyond repair and completely damaged. Shortly after his surgery and the loss of sight be started to fall into depression and I was able to see he really needed some help.

In order to reverse or prevent some types of eye damage, variations of gene-replacement, or the identifying a mutation that cripples retinas and fixing the problem by slipping a good copy of genes into the eye, could find, or even fix similar genetic defects early on. In addition to gene-replacement, stem cells, or cells in early stage of development, replace or reduce the failing retinal cells that cause blindness. Dobbs also talks about bionic retinas, or microchips that replace failed retinal cells by collecting or amplifying light. They bring a low-resolution version of sight to people with histories of blindness.

Concussions are increasingly being recognized as a public health issue. Traumatic brain injuries, like concussions, have short and long term side effects. The long term effects of concussions are not fully known, however, it has been observed that multiple concussions have cumulative effects. (Kutcher et al., 2013). Understanding the effects of concussions on brain activity is key to developing assessments and preventing future injury.

The Impact of Concussions During Football Concussions have become a major problem in athletics throughout the entire world. Head injuries can impact many athletes lives in a negative way. Hard contact to the head of a player can damage the brain and the way he goes about life. The way football is played, equipment should be better equipped to prevent significant injuries such as concussions. Head injuries drive a player out of the sport earlier than normal, so the NFL has looked into the issue and has gone about bettering technology and equipment to prevent concussions in the future.

Recently, researchers in a new study found that the effects of concussion could last for much longer than what scientists had previously guessed. After clinical recovery from concussions, we have seen a lot of athletes who still have reduced blood flow to the brain. Normally, sports-related concussions are judged based on the symptoms and through neurological tests. According to research from the Medical College of Wisconsin, athletes have decreased blood flow in the brain long after they appeared to recover from a brain injury. Despite these findings, the study did not reveal why blood flow will remain at lower levels after a person has experienced a concussion.

Some of the symptoms include: headaches, dizziness, difficulty concentrating or completing tasks, Irritability, and the sense that you “just don’t feel like yourself”. According to Dr. Maryse Lassonde, “even when the symptoms of a concussion appear to have gone, the brain is still not yet 100 percent normal.” In a study done on athletes that had concussions 30 years past then now have symptoms of parkinson's. Also further tests showed that past athletes who had a concussion experienced a thinning of the cortex in the same part of the brain that Alzheimer's

The study of the link between automated operations and inhibition has been seen by psychology scholars as one of strong importance over time. John Ridley Stroop (1935) demonstrated that a automated operation like reading words interference the execution of not automated actions. In the experiment conducted by Stroop, participants read words denoting colors (eg. Red,Yellow and Green). Regardless of what color that was written; when participants had mentioned the colour which was the written word, they did more slowly when the word "red" was written in "green" and quickly when the word "green" was written in green, ignoring ink color reduces the speed of reading.

The second group was asked to read the same two sheets however in reverse order, comparing for practice and fatigue on each test. Participants were instructed to name the colours as quickly as possibly leaving no errors uncorrected, researchers followed on another sheet recording the time participants required to complete the task. Results from this experiments led Stroop to his conclusion, that since individuals are more practiced at reading words than naming colours, there is less interference with word reading than colour naming. Other researchers have also modified the Stroop test in order to include other sensory modalities and variables. Frank H. Durgin known for the Reverse Stroop Effect experiment provided a modified version of the Stroop Test.

More now than ever athletes are being watched out for when there is trauma to the brain. After multiple cases of poor treatment to concussions parents and doctors are cracking down on letting concussions not be a big deal. As more studies advance, it is discovered that every case is different. The range is created by severity, past experience with trauma, and how the patient heals. Concussions in sports can range in severity, and how they affect each individual over time depending on times of impact.

The speed of processing theory says that colors are named slower than the words being read. The selective attention theory shows that reading words need less attention than reading color. Both theories state that words are easier to resight than colors. Perception (which is the amount of awareness about something) is another thing that is

The results revealed the surface of the iris at a higher stress was profoundly affected by a higher IOP (30 mmHg) while there is a less amount of stress distribution in the iris surface at the IOP of 10 mmHg (Fig. 4). The vitreous body, regardless of the variations in the IOP, showed almost the same amount of stress with the same distribution (Fig. 5). The amount of stress in the retina and sclera which act as holder pressure applied from the external load was different by variation of the IOPs. That is, by increasing the pressure in the aqueous body the stress in the retina and sclera are increased and decreased, respectively (Fig. 6). The crucial role of the optic nerve is to link the eye to the brain for image interpretation.
