Experimental Variables
In order to have a successful, reliable experiment you need sufficient data and evidence, reliable research, variables to test and a follow – up experiment. There are several types of variables you need to do an experiment. An independent variable is the manipulated experimental factor that is changed to see what the effects are. A dependent variable is the outcome. This factor can change in an experiment in reaction to the changes in the independent variable. An experimental group is the group of participants that are exposed to the change that the independent variable represents. The control group is participants who are treated in the same way as the experimental group except for the manipulated factor which is the independent variable (King 24). Proper data, evidence and research is also needed so the experiment turns out correctly and you know what you are testing. A follow – up experiment is not required, however it helps the validity of the conclusion of the experiment. Validity is “the soundness of the conclusions that a researcher draws from an experiment” (King 25). Conducting a follow – up experiment will help researchers and people alike see if the experiment worked properly, continues to help people and see how participants are doing after the experiment is over.
Neither article, Cookie Monster and Fighting Anorexia – New Research Into Its Origins- and Its Youngest Victims, provide adequate research and details about the study. The articles needed additional information to understand and evaluate the research that was done. To better understand the results of the studies the following information is needed: age, gender, ethnicity, the duration of the study and the setting where the study took...

...This question would see if a healthy weight is being maintained. By doing this follow up I would discover how well the treatment worked for them during the time they were participating. It would also show if what they learned while participating in the treatment and if it continued to help them even after it was over.
In this day and age anyone can write anything and put it on the internet for everyone to read. You have to be diligent in separating fact from fiction. If you are skeptical you may have to do your own research to see where the information originated. Do not believe everything you read just because it states it was from a study as it may not be reliable or truthful. Both of these studies had interesting information, however since they both were lacking sufficient data it was hard to determine if the studies were completely honest and adequate or not.
Anorexia Nervosa has been a problematic disease many women suffer from. The article “The Slender Trap” was composed by Trina Rys who is a stay at home mother with a husband and one daughter. Rys writes the main reasons a woman may develop anorexia from. She states that the psychological pressures, expectations of friends and family and influences of the media all are factors when a woman is inflicted with the disease. I strongly agree with Rys persuading argument that anorexia could be caused by an unknown identity and the overall main focus of the ideal image of a woman. Although, I believe Rys requires a stronger argument on whether food restrictions executed by parents are a major step to developing the harmful illness. She seems to put emphasize on mainly women but does not shine any light on men.
The laboratory experiment gives the experimenter a greater chance to control the conditions and enables you to measure behaviour with greater precision. This method also allows for quantative research and also enables greater control of variables. Although it gives the experimenter greater control, this can also seem daunting to the subject who may feel more uncomfortable and is less likely to ...
Going into details of the article, I realized that the necessary information needed to evaluate the experimental procedures were not included. However, when conducting an experiment, the independent and dependent variable are to be studied before giving a final conclusion.
Experimental research is the one type of research that allows psychologists to make causal statements. It is where the researcher changes one or more variables that may have an effect on some other variables (King, 2016). The hypothesis is a specific expectation about what is going to happen in the experiment (King, 2016). In the research, the hypothesis was that women would perceive fat talk to be more socially acceptable than men (Katrevich et al., 2014). The other elements of experimental method are dependent and independent variables. The independent variable (IV) is the cause of the results, and it is changed by the experimenter to find the effects, but the dependent vari...
Each year millions of people in the United States develop serious and often fatal eating disorders. More than ninety percent of those are adolescent and young women. The consequences of eating disorders are often severe--one in ten end in death from either starvation, cardiac arrest, or suicide. Due to the recent awareness of this topic, much time and money has been attributed to eating disorders. Many measures have been taken to discover leading causes and eventual treatment for those suffering from anorexia. (http://www.kidsource.com/kidsource ...er.html#Causes of Eating Disorders) )

There is argument about whether or not Anorexia can be incited by environmental factors and whether the occurrence of Anorexia is increasing at all. The article “Not Our Stars But Ourselves” stated, “Some of these causes may overlap with one another, but biomedical researchers are virtually unanimous that Anorexia has physical roots” (Schwarz). The article also question whether growing a...
Eating Disorders are on a rapid rise in the United States today, they sweep the halls of Junior High School, High Schools, College Campuses and even Elementary Schools. These disorders are often referred to by professionals as the “Deadly Diet,” however you may know them as Anorexia or Bulimia. Eating disorder effect more than 20% of young females and males in today’s society. Ranging in age from thirteen to forty. It is very rare for a child of a young age to not know someone who is suffering from an eating disorder or symptoms that are associated with one. Statistically it has been proven that one out of every five young woman suffer from serious issues dealing with eating and or weight. (Bruch, 25)
Today, America is plagued with eating disorders such as Anorexia Nervosa, Bulimia Nervosa, and Compulsive Eating Disorders. Each has its own characteristics that distinguish the illness yet there are some similarities that they also share. According to the National Eating Disorders Association, as with most mental illnesses, eating disorders are not caused by just one factor but by a combination of behavioral, biological, emotional, psychological, interpersonal and social factors. Shockingly, they also report that in the United States, there are as many as 10 million females and 1 million males that are battling with eating disorders such as anorexia or bulimia. Additionally, another 25 million are struggling with binge eating disorders (www.NationalEatingDisorders.org). Typically, psychological factors such as depression and low self-esteem contribute to eating disorders...

Does the study seem to support what Haidt (and Kahneman) are saying? Explain why, or why not.
In 1978, Brunch called anorexia nervosa a 'new disease' and noted that the condition seemed to overtake ?the daughters of the well-to-do, educated and successful families.? Today it is acknowledged and accepted that anorexia affects more than just one gender or socio-economic class; however, much of the current research is focused on the female gender. ?Anorexia nervosa is characterized by extreme dieting, intense fear of gaining weight, and obsessive exercising. The weight loss eventually produces a variety of physical symptoms associated with starvation: sleep disturbance, cessation of menstruation, insensitivity to pain, loss of hair on the head, low blood pressure, a variety of cardiovascular problems and reduced body temperature. Between 10% and 15% of anorexics literally starve themselves to death; others die because of some type of cardiovascular dysfunction (Bee and Boyd, 2001).?
A researcher uses an experiment to scientifically test out a hypothesis. In an experiment there are many different factors that are involved. There is the independent variable, which is the cause, it is the one that is being manipulated, and the dependent variable, which is the effect, is the response. When conducting a experiment it is important to make sure that the only thing than can affect the dependent variable is the independent variable. This is known as internal validity. Using random assignment to separate the participants into groups helps eliminate any outside factors, and creates an equal chance for all participants to be apart of the experimental conditions. There are many pros and cons to this type of method. The experimental method creates a strong control of the variables involved in the experiment, which allows an easier determination on cause and effect. If needed, it is fairly easy to replicate an experiment and is less time consuming than other research methods. However there are many downfalls as well. When conducting an experiment the setting of where the experiment is taking place is more artificial which may cause certain behaviors that wouldn’t occur in real life. This is known as external validity, which is the measure of how much the results of a study can be generalized and used in different situations, and people. To improve external validity cover stories are created when conducting experiments so the participants are not aware of what is really going on, or experiments are done in a natural setting as opposed to in a laboratory. However, this creates less control over confounding variables that can affect the experiment, which can create bias results (Aronson,
