Review of Literature The Stroop effect
The stroop effect is a used to measure your mental vitality and flexibility. The effect is named after John Ridley Stroop it takes advantage of our brain's ability to read words more quickly and automatically than we can name colors. The words have a strong influence over your brain to say the color. The different information (what the words say and the color of the words) your brain receives causes the problem. The Stroop effect shows how the brain deals with different information. The interference is caused by one side of the brain dominating the other one wants to read the word and the other side wants to say the color. The brain has limited attention resources.

As people age, the number of nerve cells in the brain decreases but the number lost is most of the time different from person to person, according on the person's health. The nerve cells that are left start to work slower. (Steven A. Goldman 2012)
The Human Brain
The brain is a thinking organ that learns and grows by interacting through perception and action. Mental stimulation improves brain function and actually protects against cognitive decline. The human brain is able to continually adapt and rewire itself. Even in old age, it can grow new neurons. Severe mental decline is usually caused by disease, whereas most age-related losses in memory or motor skills simply result from inactivity and a lack of mental exercise and stimulation. In other words, use it or lose it. (Than, Ker 2007)
The Test This test is checking your brain's ability to separate the left brain functions and right brain functions. The problem is that the left side of your brain is trying to tell you to read the word, while at the same time; the right side of your brain is trying to tell you to identify the color. (Steven Novella
As a child, we have little that takes up space in the memory bank of our brains, but as time goes on we develop new memories, develop beliefs based on new knowledge. We access those old memories less and less, making the reliability of those earlier memories questionable. On the other hand, suppose a person has developed a mental disorder or age has caught up to them and they suffer from Dementia or Alzheimer's, the reliability of their memories would also be questionable but on the grounds that their minds aren’t functioning
Two of the most important concepts are the Strain theory by Robert K. Merton and General Strain theory by Robert Agnew. Strain theory describes that society puts pressure on individuals to achieve socially accepted goes such as the American dream. Though they lack the means to have the American dream, which leads to strain, but might lead to the individuals to commit crimes. On the other hand, Robert Agnew’s General theory describes as seeing crime as a coping mechanism to help people deal with socioemotional problems that are generated by negative social relations. Each member of society has similar goals and aspirations.
Dementia Is a Normal Part of Aging Although, age
The Stroop effect was established by John Ridley Stroop in 1935 and has since become increasingly influential through its replication in published works. This effect illustrates the interference in human perception (Hilbert, Nakagawa, Bindl, & Buhner, 2014) and is a perfect example that describes situations in which task-irrelevant stimuli are hard to ignore. This study aims to investigate whether the fast and automatic processing of the colour denoted by a word will interfere with the ability to identify the font colour of the word. According to Raz, Moreno-Iniguez, Martin and Zhu (2007), Stroop effect is the difference in response time between congruent and incongruent stimuli – increase in time taken to name the font colour when it differs from the colour denoted by the word
A group of scientist conducted research on children aged between 2 and 9 months. Researchers showed pictures to infants: the backgrounds were in different colours (red, green, blue and yellow) and had either circles or triangles drawn on in black. If babies did not have synaesthesia, they would observe all the pictures for the same amount of time, regardless of shapes drawn. However, if they saw shapes in specific colour, i.e. one of them always saw circles in green, then that infant would look at a picture of circles on a green background longer, than on a background of any other colour. Observations confirmed the theory.
Dementia is a disorder which causes the brain cells to deteriorate therefor causes a decline in several symptoms and affects a person’s mentality, capacity and how they go about their everyday life. NVQ 1.2 2) Describe the functions of the brain that are affected by dementia. There are many brain functions affected by dementia depending on which form of dementia the individual has. The temporal lobe’s functions affected are Memory loss for example forgetting things you have just been told or something you have just said so repeating yourself several times, balance, posture and vision can also be affected due to decline in health of the temporal lobe. Frontal lobe affects behaviour for example becoming withdrawn.
The term ‘dementia’ is an umbrella term for a range of progressive conditions that affect the brain. Doctors typically use the word ‘dementia’ to describe the common symptoms such as memory loss, confusion and problems with speech and understanding. Each type of dementia stops an individual’s brain cells working in specific areas, namely their ability to speak and remember things. 1.2 -Describe key functions of the brain that are affected by dementia The brain is made up of four lobes, namely frontal, temporal, parietal and occipital, all of which have different functions.
This test can be inconsistent because sometimes I would answer questions correctly regardless of how they are associated but unconsciously. Because this measured my speed, I would answer the not always with the picture shown, but with the word associated with. For example, if thin individuals and
Sol Lim, like Kaiser, agrees with the previous statement and talks about how the lack of connectivity throughout the brain development can essentially help recover and enhance the brain functions by rearranging the systems more effectively (Knapton, 2013, para.9). Considering that fact, instead of approaching so many people when you are lost, you can ask people who have lived in the area for the longest time and easily find your way around (Knapton, 2013, para.10). In a comparable method, decreasing some predictions in the brain assists in emphasizing on crucial knowledge, such as connecting the sound of an accustomed person’s voice to their face (Knapton, 2013, para.12). While examining the brains of 121 volunteers amongst the ages of 4 and 40, they established important alterations. Earlier studies show that the brain re-organizes itself and that there is more activity all throughout puberty (Knapton, 2013, para.13).
However, there is a very distinct difference between forgetfulness and the beginning symptoms of Alzheimer’s and dementia. The symptoms for this disease begin to affect the part of the brain that relates to learning. Having no memory whatsoever of newly learned things is an unfortunate symptom of the beginnings of this brain degenerative disease. The brain cells will continue to be affected and other parts of the brain will begin to show more severe symptoms. Loss of short term memory will lead to long term.
Design In this replicated study of the Stroop Effect, there were several replicated measures, resulting in a longitudinal study that represents a collection of data collected through changes in time with each of the participants. In this repeated experiment, it presented demonstrations of how distractions or in this case, directions that do not correspond to the word may lead into cognitive difficulties, taking a longer period of time to understand cognitively. In simpler terms, In this replicated study, there was a separation between the experimental group and the control group. In the control group, participants were only exposed to the sets of words (24 sets) that correspond to the directions.
Research has shown that, just like the body, the brain gets weaker as we age. Our brains get smaller and that causes us to process things much slower. The impact of this depends on the person and their gene pool. This article refers to a 2015 MIT study on the brain which states “The majority of mental processing skills like
Dementia is one of the diseases of the nervous system, and it is particularly common in older people. It is the result of extensive damage to the connections of the cerebral cortex and neurons. This damage prevents efficient conduction of impulses as a result dementia patients suffer from memory loss, impaired judgment and a Loss of communication skills. Large tumours, HIV, intoxication and repeated brain infarctions which destroy large volumes of tissue cause dementia.
Three conditions were looked at in this research study, congruent, incongruent and neutral. In the congruent condition, participants could rely on reading processes to enable fast and precise responding. In the incongruent condition, participants were supposed to rely more on colour naming processes and reduce the reading words process. The Stroop task had shown that participants had made more errors in the incongruent trials than the congruent trials. Similarly, it also showed that the time that they took to respond was longer for incongruent trials than congruent trials.
"At a certain age"it is in our nature to wear out, and die, and that is that." This overlooks about human nature. We possess the only nervous system that is aware of the phenomenon of aging. Old lions and tigers do not realize what is happening to them—but we do.
