In this experiment we are going to describe stress and prove how can a prolonged exposition to it have a negative impact on memory. The definition of stress used in this experiment is: difficulty one suffers that causes worry‚ emotional tension or loss of concentration. The reason why this topic has been chosen is because stress is a part of nowadays‚ hectic society and it has a very noticeable effect on people’s performance‚ in either work or daily life. The outcome of this experiment could be

This assignment called for me to pick three out of four sensory experiments to conduct and then record my reaction to each experiment. The three experiments I chose to conduct are number one- the sandpaper experiment‚ number three- the index cards and flashlight experiment and number four- the water in bowls experiment. While conducting each of these three experiments I was surprised by the results of each of them. Experiment Number One: I rubbed my finger on the piece of coarse sandpaper and

Introduction The brain is one of the most complex machines to ever exist. Many experiments are conducted to try to learn more about the brain. Within the Bransford & Johnson experiment‚ their experiment focusing on the memory aspect of the brain. They focus on schema theory which was proposed by J. Piaget. Schema is the mental framework that helps interpret information by comparing new information to pre-existing knowledge. This study was conducted in 1972 by Bransford and Johnson. The aim of

Introduction The common bean (Phaseolus vulgaris) is a fast growing plant and is used commonly in experiments due to its easy testability. It can grow in a variety of conditions and is easy to see the effects of different treatments. The idea of the treatment that we applied to our bean plants came from our class and scientific papers that help back our experiment. Examining many studies on the effects of nitrogen fertilizer on a variety of plants helped us better understand what the fertilizer was

Success of Dugesia tigrina regeneration in different water temperatures Abstract: The experiment at hand aimed to determine if the species Duguesia tigrina has an optimal temperature for regeneration. The experiment used three different spring water treatments of different temperatures. The treatments included a cool 12° treatment‚ a room temperature 25° treatment‚ and a warm 30° treatment. Each of the D. tigrina were cut in half‚ and each half was placed into a designated section of a water treatment

The aim of the experiment was to examine the effects that having a rich lipid diet had on the CHO and fat metabolism during the prolonged exercise. The data shows that at rest the body was in a heavy fat metabolism and when exercise started there was a shift of metabolism from fat to CHO. After thirty minutes‚ the metabolism shifted back to a primary metabolism of fat. Examining the data from this experiment to other studies showed a similar result.

THE STANFORD EXPERİMENT What happens when you put good people in an evil place? How the environment affect behaviours ‚ attitudes or beliefs of people? Philip Zimbardo was interested in this questions. Zimvardo choose a prison enviroment as the evil place. Zimbardo prepare the basement of Stanford University Psychlogy Department like a prison to avoid security problems. All of the conditions in basement change for experiment such as guards uniform ‚ prisoners overalls‚ grates ‚ dark cell etc.Zimbardo

horrifying medical experiments that took place involving concentration camp prisoners as “test” patients. Not only did these experiments violate the basic rights of human beings‚ but they were an absolute insult to humanity. While this topic is a very uncomfortable‚ and one that makes you question the minds of the people who conducted these experiments‚ it is one that is necessary so that we may become educated and not allow history to repeat itself. Over thirty experiments were conducted on prisoners

Examine the problems some sociologists may face when using experiments in their research. (20 marks) (January 2009) MODEL ANSWER Experiments are the preferred scientific method. There are two main types of experiments. The classic scientific experiment takes place in a laboratory in controlled conditions. By contrast field experiments take place in more natural but less controlled experiments. Although experiments are very successful in science they are rarely used in Sociology for the following
