While there are a number of different research techniques, the experimental method allows researchers to look at cause-and-effect relationships. In the experimental method, researchers identify and define key variables, formulate a hypothesis, manipulate the variables and collect data on the results. Extraneous variables are carefully controlled to minimize a potential impact on the outcome of the experiment.?? A Closer Look at the Experimental Method in Psychology The experimental method involves manipulating one variable to determine if changes in one variable cause changes in another variable. This method relies on controlled methods, random assignment and the manipulation of variables to test a hypothesis. Types of Experiments There are a few different types of experiments that researchers might choose to use. The type of experiment chosen might depend on a variety of factors including the participants, the hypothesis and the resources available to the researchers. 1. Lab Experiments Lab experiments are very common in psychology because they allow experimenters more control over the variables. These experiments can also be easier for other researchers to replicate. The problem, of course, is that what takes place in a lab is not always identical to what takes place in the real world. 2. Field Experiments Sometimes researchers might opt to conduct their experiments in the field. For example, lets imagine that a social psychologist is interested in researching prosocial behavior. The experimenter might have a person pretend to faint and observe to see how long it takes onlookers to respond. This type of experiment can be a great way to see behavior in action in realistic settings. However, it makes it more difficult for the researchers to control the variables and can introduce confounding variables that might influence the results. 3. Quasi-Experiments While lab and field experiments represent what is known as true experiments, researchers can also utilize a third type known as a quasi-experiment. These are often referred to as natural experiments because the researchers do not have true control over the independent variable. Instead, the treatment level is determined by the natural conditions of the situation. A researcher looking at personality differences and birth order, for example, is not able to manipulate the independent variable in the situation. Treatment levels cannot be randomly assigned because the participants naturally fall into pre-existing groups based on their birth order in their families. So why would a researcher choose to use a quasi-experiment? This is a good choice in situations where scientists and interested in studying phenomena in natural, real-world settings. It is also a good choice in situations where researchers cannot ethically manipulate the independent variable in question. Key Terms to Know In order to understand how the experimental method works, there are some key terms you should first understand. The independent variable is the treatment that the experimenter manipulates. This variable is assumed to cause some type of effect on another variable. If a researcher was investigating how sleep influences test scores, the amount of sleep an individual gets would be the independent variable. The dependent variable is the effect that the experimenter is measuring. In our previous example, the test scores would be the dependent variable. Operational definitions are necessary in order to perform an experiment. When we say something is an independent variable or dependent variable, we need to have a very clear and specific definition of the meaning and scope of that variable. A hypothesis is a tentative statement or guesses about the possible relationship between two or more variables. In our earlier example, the researcher might hypothesize that people who get more sleep will perform better on a math test the next day. The purpose of the experiment is then to either support or fail to support this hypothesis. The Experimental Process Psychologists, like other scientists, utilize the scientific method when conducting an experiment. The scientific method is a set of procedures and principles that guide how scientists develop research questions, collect data and come to conclusions. The four basic steps of the process are: Forming a HypothesisDesigning a Study and Collecting DataAnalyzing the Data and Reaching ConclusionsSharing the Findings Most psychology students will be expected to use the experimental method at some point. If you want to take a closer look at the process, be sure to check out a step-by-step breakdown of how to conduct a psychology experiment for more information.

Analytical Essay If I Were An Animal Would You Eat...

HLTC50 Assignment 2, Analytical Essay on Prompt 2: â€Å"If I Were an Animal, Would You Eat Me?† There is a common English idiom: â€Å"A picture speaks a thousand words.† Art is a powerful tool that can cross cultural barriers and connect strangers without speaking a word. It can also make us question about our society and see the world with different eyes – including the eyes of another species. Paintings are influential in raising awareness of the social problems regarding the human-animal interface by allowing us to be alert to human conditions and be critical on our definition of morality and what makes us human. A painting by Sue Coe illustrates the disturbing reality of animal farming by comparing it with human enslavement. Her provocative†¦show more content†¦Sue Coe brilliantly painted a connection between human and non-human and questioned about the boundaries that separates the human from the animal. The pig is being dragged away by the two men, but shown to be standing on her two feet. In the study of biology and evolution, humans (specifically Homo sapiens) are identified and separated from other species by having bipedal locomotion. In other words, they are capable of standing and walking upright on their two feet. Thus interestingly Sue Coe broke the barrier by giving a humanistic personification to the pig by making her stand vertically between the butchers. It gives uncomfortable thoughts on what if the butcher was holding onto the arms of a human in this particular situation? Undeniably, the audience is tackled with problem on morality. Through the approach of using anthropomorphism on the farm animal, Sue Coe was able to create empathy between the individual and the pig. The personification of the pig challenges the person to revaluate their identity as a human and pounder what makes the human different from the non-human. How would we react if there was human farming in the place of an animal slaughterhouse? Similarly to Sue Coe’s method of giving personhood to the pig, Sunaura Taylor uses painting to display the opposite to when a human becomes a farm animal. Particularly to the painting called â€Å"Self-Portrait Marching with Chickens† Taylor submerges herself into the field and uses her body to re-enacts the

Madeline Barnard Essays (530 words) - Analgesics, Euphoriants

Madeline Barnard HS-102-01 Professor Coffey 11 October 2016The Opium War From the years of 1839 to 1842 and 1856 to 1860 the Opium Wars started a fight for power between China, and the west. During this time period many events accrued which lead to the repair of the relationship between China and the west. Slowly with many treaties were signed and the opium trade came to a stop ending the wars. The Opium Wars was a time of conflict that gradually resolved over time. Britain was a major power that played a part in the opium trade, both Britain and China fought about the abolishment of the trade of opium. But there were other concerns that caused the hostilities. Some other concerns that caused the hostilities were how the British wanted to open China's ports because they rejected Lord George McCartney offers to have direct trade ties with Britain and emperor (Purdue). Additionally, both Britain and China abused their prisoners and used other barbarous behaviors (Purdue). Also, Chinese scholars were concerned and confused how to handle the situation of the new European influence that was seen in their country. This is because some of the Chinese scholars liked the European influences, while others wanted everything to stay the same (Purdue). One global circumstance that contributed to the conflict of the opium trade was how Britain was obtaining the opium. Since China demanded to be paid in silver, Britain needed to find a solution because they were afraid that their country would run out of silver. They decide to trade to China in a very conniving way. Britain came to a conclusion that they would trade Opium to India and receive silver as payment. Then Britain would give the silver they received from India to China to get the goods they needed. This was another factor that contributed to the Opium War. Although, Britain did play a big part in the Opium War so did the United States. The United States signed The Treaty of Wangxia, which ended the Opium war and established five treaty ports for the western nations. The treaty also created a crossword for Chinese's and Western culture (Article). This made trading between the countries much easier and something they have been working towards for many years. Both The United States and Britain both used China but it was for their own good. For example, as the volume of trade grew, however, the British demanded greater access to China's markets. Tea exports from China grew from 92,000 pounds in 1700 to 2.7 million pounds in 1751 (Article). Both countries were doing what was best for them and what would benefit their country. Furthermore, it is shown that a new relationship was formed between China and the rest of the world by opening treaty ports. Throughout this time period, there was conflict throughout China and the west. Eventually by signing a treaty the conflict was resolved and new treaty ports were opened. Creating an open trade system throughout the world. Even though the west took advantage of China, in the end, it all worked out for the better.

Gun Control misc8 essays

Gun Control misc8 essays Since the days of the pioneers of the United States, firearms have been part of the American tradition as protection and a means of hunting or sport. As we near the end of the 20th century the use of guns has changed significantly. Because of fast and steady increase in crime and the fight for the right to own a hand gun, the introduction of legislation for gun control, to try to reduce the crime in the United States, has been a hotly debated issue in recent years. Although many people feel that gun control violates the right of the people, given in the second amendment "the right to bear arms", controlling distribution and sales and the registration of guns and gun owners is necessary because of the homicide rate involving guns and the violence by criminals using guns. Many people feel that gun control violates the right of the people given in the second amendment the right "to bear arms". Opponents of gun control, including the National Rifle Association, better known as the NRA, argue that the "right To bear arms" is guaranteed in the second amendment of the Constitution of the United States of America and licensing restrictions penalize law-abiding citizens while in no way preventing criminal use of handguns. It is also argued that by making it difficult for guns to be bought and registered for the American public there is a threat to the personal safety of American families everywhere. However controlling the sale and distribution of firearms is necessary because of the homicide rate involving guns. In 1988 there were 9000 handgun related murders in America. Metropolitan centers and some suburban communities of America are setting new records for homicides by handguns. Larger Metropolitan centers have ten times the murder rate of all Western Europe. For example in Washington,D.C. there was an estimated 400 homicides including guns. In addition gun control has been seen as necessa...

Aaron Douglas, Harlem Renaissance Painter

Aaron Douglas, Harlem Renaissance Painter Aaron Douglas (1899-1979) was one of the pioneers of the development of African American art. He was a significant member of the Harlem Renaissance movement of the 1920s and 1930s. Later in his life, he promoted the development of arts education in African American communities from his position as the first head of the art department at Fisk University in Nashville, Tennessee. Fast Facts: Aaron Douglas Occupation: Painter, illustrator, educatorStyle: ModernistBorn: May 26, 1899 in Topeka, KansasDied: February 2, 1979 in Nashville, TennesseeEducation: University of NebraskaSpouse: Alta SawyerSelected Works: Cover images for The Crisis (1926), Illustrations for James Weldon Johnsons Gods Trombones: Seven Negro Sermons in Verse (1939), Mural series Aspects of Negro Life (1934)Notable Quote: We can go to African life and get a certain amount of form and color, understanding and using this knowledge in development of an expression that interprets our life. Early Life and Education Born in Topeka, Kansas, Aaron Douglas grew up in a politically active African American community. His father was a baker and highly valued education despite his low income. Douglas mother was an amateur artist, and her interest in drawing inspired her son, Aaron. Following high school graduation, Aaron Douglas wanted to attend college, but he couldnt afford the tuition. He traveled to Detroit, Michigan, with a friend and worked in a Cadillac plant while attending art classes in the evening at the Detroit Museum of Art. Douglas later reported being a victim of racial discrimination at the Cadillac plant. In 1918, Douglas was finally able to enroll at the University of Nebraska. While World War I raged in Europe, he attempted to join the Student Army Training Corps (SATC), but they dismissed him. Historians speculate it was due to racial segregation in the military. He transferred to the University of Minnesota where he rose to the rank of corporal in the SATC before the end of the war in 1919. Returning to Nebraska, Aaron Douglas earned a Bachelor of Fine Arts degree in 1922. Invincible Music: The Spirit of Africa for The Crisis (1926). New York Public Library / Public Domain Aaron Douglas fulfilled a dream of moving to New York City in 1925. There he studied with artist Winold Reiss, who encouraged him to use his African heritage for artistic inspiration. Reiss drew on the legacy of German folk paper-cuts for his work, and that influence is seen in Douglas illustration work. Soon, Aaron Douglas found his reputation as an illustrator rising quickly. He earned commissions for the National Urban Leagues magazine The Crisis and the NAACPs magazine Opportunity. That work also led to work for nationally popular magazines Harpers and Vanity Fair. Harlem Renaissance Modernist Painter By the final years of the 1920s, writers such as Langston Hughes, Countee Cullen, and James Weldon Johnson considered Aaron Douglas part of the movement known as the Harlem Renaissance. Early in the following decade, Douglas began painting mural commissions that brought him national fame. Aspects of Negro Life: The Negro in an African Setting (1934). New York Public Library / Public Domain In 1934, with funding from the Public Works Administration, Aaron Douglas painted his best-known set of murals, Aspects of Negro Life, for the Countee Cullen branch of the New York Public Library. For subject matter, Douglas drew on the history of the African American experience from slavery through the Reconstruction to twentieth-century lynching and segregation. The panel The Negro in an African Setting shows Douglas at the peak of his powers. It depicts life in Africa before slavery as joyous, proud, and firmly rooted in the community. Aaron Douglas became the first president of the Harlem Artists Guild in 1935. The organization promoted young African American artists and lobbied the Works Progress Administration to provide more opportunities for them. Arts Educator In 1938, Aaron Douglas earned a fellowship from the Rosenwald Foundation, a generous provider of stipends to hundreds of African American artists and writers. The funds allowed him to travel to Haiti, the Dominican Republic, and the Virgin Islands and create watercolor paintings of life there. Aspects of Negro Life: Song of the Towers (1934). New York Public Library / Public Domain Upon returning to the U.S., Charles S. Johnson, the first African American president of Fisk University in Nashville, Tennessee, invited Douglas to create the universitys new art department. Aaron Douglas served as head of the art department until his retirement in 1966. President John F. Kennedy invited Aaron Douglas to the White House to participate in ceremonies honoring the 100th anniversary of the Emancipation Proclamation in 1963. Douglas continued to appear as a guest lecturer after retirement until his death in 1979. Legacy Aspects of Negro Life: From Slavery to Reconstruction (1934). New York Public Library / Public Domain Some consider Aaron Douglas to be the father of black American art. His modernist style laid a framework for the development of art in African American communities. The bold, graphical style of his work is echoed in the work of many artists. Contemporary artist Kara Walker exhibits the influence of Douglass use of silhouettes and paper cut-outs. Source Ater, Renee. Aaron Douglas: African-American Modernist. Yale University Press, 2007.
