Stroop Effect The “Stroop Effect” was named after John Ridley Stroop who discovered this occurrence in the 1930s. The stroop effect is used in many clinical and psychological applications. It is often used to compare the brain development of early school age children. It has been found that interference is often present in conditions such as brain damage, dementia, ADHD, alcoholism, addiction such as drugs and gambling.
The stroop effect works by the use of words on their own have a much stronger influence over a person’s ability to say the color. The interference that occurs between the different information received by the brain causes a conflict to occur which happens because of what the words say and what the color of the words mean.
Evidence for the existence of the phonological loop comes from Baddeley (1966 in Passer, 2009) They examined the word length effect in which they presented participants with visual presentations of word lists and asked them to write t...

Dr. Margaret Bauman, (Dept. of Neurology, Harvard Medical School and a child neurologist at Massachusetts General Hospital in Boston), and Dr. Thomas Kemper (Depts. of Neurology, Anatomy, and Pathology, Boston University School of Medicine) have a different hypothesis (3) which nonetheless correlates with Courchesne's theory. They believe that a dysfunctional ne...
The principle of the double effect has come to have a very respected and influential position in medical ethics. This doctrine is often employed to explain the morality and validity of an action that may have harmful consequences—such as the death of a human as a “side effect” of advancing another good end. The principle goes that in certain situations, it is permissible to cause serious harm as long as, the good effect of the act is proportionately good enough, and the agent, while foreseeing the bad effect, only intends the good effect and not the bad one (Thomson, 1999). In Judith Jarvis Thomson’s article Physician-Assisted Suicide: Two Moral Arguments, Thomson further explores this principle with respect to the relevance of the difference
...orrect with the individual subject’s gender or dominant brain hemisphere, but it does measure the effect of both the angle and the object type. There will likely be effects of both the angle and object type on reaction time, due to not only a dissimilarity between the objects and what the subjects are used to seeing, but also because of the unfamiliar nature of the random 2-dimensional figures.

Roger Sperry is one of the big Neurobiologists in the 1950’s. Sperry studied the relationship of the right and left hemispheres of the brain. In one of his experiments he flashed the word “Fork” in front of the patient. If the patient was asked to say the word he could not but if asked to right the word he would start to right the word “Fork”. This happed when the two brain hemispheres were disconnected from each other. At an another experiment he placed a toothbrush in the patients left hand and blind folded the patient and was asked to identify it they could not do it. But if placed in the right hand the patient would know right away what it was. That is just one of the types of study he did in his time.

Everyone has experienced hearing a language they do not understand. In that context, the words seem to consist of a meaningless series of sounds; this is often ascribed to the listener not knowing the definitions of the vocabulary used. However, in addition to not being familiar with the words said, a person who does not understand the language will hear and process the sounds differently than a native speaker. This fact is partially explained by categorial perception, a perceptual-learning phenomenon in which the categories of different stimuli possessed by an individual affect his or her perception.

Certain changes to the brain that are experienced more within young brains, tend to be more adaptive and responsive to situations that an older brain tends to be more maladaptive to. Neuroplasticity happens most in the first years of life and decreases as the human body ages. Children are more likely to recover at faster rates from head injuries than adults. It has been shown that they can recover their brain functions faster due to neuroplasticity. There are four types of neuroplasticity in children; adaptive, excessive, plasticity, and adaptive. Plasticity makes the brain virtually vulnerable to injury. Adaptive neuroplasticity is the changes that allow children to have special skills and to adapt to them. Impaired neuroplasticity occurs when genetic disorders change molecular pathways. Excessive neuroplasticity can lead to disabilities and seizures because the brain is not meant to change too often. [4] As the human body ages, it has been found that there is more of a maladaptive function which negatively impacts the brain and the body.[5] Margaret Kennard came up with a principle called the Kennard principle. This principle states that the younger the brain is, the more likely it is that it will be able to recover from trauma.[6] The Kennard Principle also can be argued against because of the fact that preterm infants have the probability of possessing numerous mental
As Director of Human Resources for People, people who need people.com, I have created the following training proposal which will include common problems that occur when managers complete performance reviews and suggestions for supervisors on how to eliminate or reduce these problems.
I chose to examine color 's effect on communication for several reasons. First, I find it interesting. It helps a person realize what to and not to wear to give a presentation or on a date. Color 's effect on our attitude plays into interior design when painting walls, although it is not exactly communication.
