The Stroop Effect

The stroop effect is a demonstration of reaction time of a task. They call it "stroop" because of a scientist named Ridley Stroop who published the effect in 1935 in an article entitled Studies of interference in serial verbal reactions, there 3 detailed experiment that he did.

In his experiment the task required the participant to read the written color names of the word independently of the color ink. In the next experiment the person had to say the color of the letters independently, and also had to name the color of the dot squares. This could be confusing and may take some time because the word could say "yellow" and the word is colored in green, but if you try to focus on the color and not the word it would be less confusing. This experiment allow the participant to read the color list a quick as possible to test the persons reaction time. This effect is used most commonly in psychological evaluations. The Studies of the Stroop effect have consistently revealed activation in the front lobe and more specifically in the anterior cingulate cortex and dorsolateral prefrontal cortex, two structures hypothesized to be responsible for conflict monitoring and resolution. People who have frontal lesions obtain a lower punctuations in the stroop test.

Multi-task Questions

1.Why is multitasking considered by many psychologists to be a myth?

Multitasking is a myth because you can't do 2 things at the same time because after someone perfomes an act they will move one to the next act, and keep jumping back and forth.

2.To what does the term "response selection bottleneck" refer?

Respones seletion bottle neck refers to the brain to respond to several stimuli at once. This causes people to loose time.

3.David Meyer has found that multitasking contributes to the release of stress hormones and adrenaline. Why is this important?

The release of stress hormones can damage your health, it leads to conflict of short term memory. Now that we know about this we can lower the cause.

4.Explain what Russell Podrack found regarding multitasking.

He found out that multi-task can affect the way we learn. When you multitask you do not recieve information efficiently, and you will not learn well.

5.What does the author conclude could happen to our culture as a result of increased multitasking?

He concludes that multitasking means the art of paying attention, the ability to shift our attention, and to exercise judgment about what objects are worthy of our attention. William James, the great psychologist wrote a book called "The Principal of Psychology" in 1890.

The Mbuti Tribe

The Bambuti are pygmy hunter-gatherers, They travel in groups and they are small in size ranging for 15 to 60 people, but overall the population is about 30,000-60,000 people. There 4 types of cultures that the Bambuti learn: the Efe, the Sua, the Mbuti, and the Aka. They live in the forest of Ituri, its 70,000 square kilometers of forest, there is large amount of rainfall nearly about 50 to 60 inches of rain. There Religion has do with the forest they consider that the trees are there greatest protector they somtimes call there protector "mother" or "father". Colin Turnbull was a famous anthropologist, he first realized that distance affected perception because he went with Kenge, and he saw buffalo from a distance and he asked Turnbull want kind of insects are they, but then Kenge was socked when Turnbull told him that it was buffalo from a distance. Kenge knew that buffalo where not small.


The pygmy would also be socked the same way as Kenge did because since they live in a forest the trees block there view, and because of that they know less about reality than we do. Everything is learned by experience.

Colin Turnbull's Life

Colin Turnbull was born on November 23, 1924, and died on July 28, 1994. He was a famouse British American anthropologist and he was one first ones to work in the field of ethnomusicology. He was educated at Westminister School and Magdalen Collage, Oxford where he studied politics and philosphy. In 1951 after he graduated from Banaras he traveled to Democratic Republic of Congo with Newton Beal, and a school teacher that he meet at India.

Turnbull studied the BaMbuti during that time, though that it was not the goal of the trip. He later was working for the Hollywood producer Sam Spiegal, he hired Turnbull to assist in the construction and transportation of a boat needed for his film. The boat was called The African Queen which was used for the fim of the same title. Turnbull became a natrulized citizen of the United States in 1954, after he was named curator in charge of African Ethnology at the American Museum of Natural History in 1959 and he moved to New York City.

Colin Turnbull's life long affair with the African Pygmies made him one of the most famous intellectuals of the 1960s and 1970s. In an intimate portrait of a remarkable man-at various times a gold-miner, builder of The African Queen and anti-death penalty advocate-Grinker describes how Turnbull fell in love with a beautiful, poor African American named Joe Towles who became as much Turnbull's heroic creation as did the Pygmies.

Perception Influence

The internal perception are thought that come from our inside that changes our views of reality for example, if you here an explotion you will think that it was a car crash, an airplane, or a movie. An external perception is what really is going on around us, it is what builds our internal perception. For example if you see a car crash from your house and you heard the noise, the next time you hear a crash you will asume it is car, not only that but our family, enviorment, public, and the TV can all change the way we view things. Sometimes we can get bad perceptions of things that happen around us.

Perception is Reality

Perception is the process of obtaining awareness or understanding of sensory information. Perception is one of the oldest fields of philosophy. Two types of consciousness are considerable regarding perception: phenomenal (any occurrence that is observable and physical) and psychological. The difference everybody can demonstrate to him- or herself is by the simple opening and closing of his or her eyes: phenomenal consciousness is thought, on average, to be predominately absent without sight. Through the full or rich sensations present in sight, nothing by comparison is present while the eyes are closed. Using this precept, it is understood that, in the vast majority of cases, logical solutions are reached through simple human sensation. The analogy of Plato's Cave was coined to express these ideas.

Perception and Reality

In the case of visual perception, some people can actually see the percept shift in their mind's eye. Others, who are not picture thinkers, may not necessarily perceive the 'shape-shifting' as their world changes. The 'esemplastic' nature has been shown by experiment: an ambiguous image has multiple interpretations on the perceptual level. The question, "Is the glass half empty or half full?" serves to demonstrate the way an object can be perceived in different ways.

Why am in IB Psychology

I am in IB psychology because ive herd that IB art you have to study important artists and have to right an essay about them, so instead I chose psychology and anyway I enjoyed the class last year and learned allot about humen behavior. I would assume that i would learn more about humen
