Experimental Research and The Key Components of
A Successful Experiment
February 4, 2013
This paper explores the experimental research method and specifically the experiment conducted by Professor Smith, a Psychology professor who has a hypothesis that Vitamin E improves memory, to determine the flaws in her experiment. In the process, the paper also clearly explains the various key factors which determine the outcome and accuracy of the method of experimental research, such as dependent variables, independent variables, experimental groups, and control groups. This paper examines the factors that render Professor Smith’s experiment as flawed, and finally attempts …show more content…
This could easily have had a demoralizing effect on the mental state of the control group and an encouraging effect on the experimental group, which would decrease the accuracy and validity of her findings as other factors beside the independent variable could have affected the dependent variable. Another flaw with her experimental design is the division of the experimental group and the control group into two seperate sections, creating a social inequity, specially as the first half of the students were allowed to sit in the front and the latter half were made to sit in the ramaining half of the class in the back. This could have created a sense of expectancy in the experimental group and compelled them to try harder, while the control group might have assumed they weren’t expected to do well and as a result not strive enough to succeed. According to Feldman and Dinardo ( 2012 ), one of the factors that distort how the independent variable affects the dependent variable in an experiment is participant expectations. The participants in Professor Smith’s experiment were aware of their assigned groups, which could have raised or lowered their expectations, depending on the group to which they were assigned. Finally, the flaw with Professor Smith’s conclusion is that the experiment was conducted to test her hypothesis that Vitamin E

Negative reinforcement increases the probability of a response that removes an adverse condition. This would include the expectations that the student get an eighty percent on tests. A personal example of behaviorism in the class of the author of this paper is included as part of this essay. The author had a class teaching algebra to a junior high class. One particular year, the group of students in class were poorly behaved. They were disruptive, disrespectful and defiant of the rules of the class. The author called a meeting with the class and explained that there would be new rules which each would have to follow. Instead of telling the students what the rules were, the author let the student decide on what they would be. The students created the rules as well as the consequences which they felt were fair. Hence, the new rules were written on the board and voted on. The students reacted positively and participated whole-heartedly. Hence, taking part of the planning, there is a sense of ownership, accountability and motivation. Along with
Hypothesis: The hypothesis was that people who normally have a high desire to control situations in their lives are less likely to conform to the group norm in certain types of situations than those who have a low desire for control.
There is evidence that people conform to the role that they are appointed to. Participants in both experiments had a tough time adjusting to the idea of what was happening but continued until the end. Once the studies
From doing a quick scan around the room, I noticed there were roughly twenty of us in attendance, quite unusual for a huge, auditorium-like classroom. Even stranger was the fact that exactly half of us were male and the other half female. I’m not saying this is the case, but there is a chance we were brought together by design.
Moreover, this social experiment took place outside of Convocation Hall in the middle of the field. It was around 1:00PM and a mass amount of students were leaving their classes. The tester saw this as the best opportunity to begin. The tester
At the school's pep rally, anybody who had a lackluster attitude and wouldn't get in the school spirit would get kicked out and be forced to sit the rest out.
They were able to control the curricula and everything about the entire learning experience along with conducting small scale complimentary experiments to better understand why the effects observed were happening. The hope was to determine which key skills children should acquire to prepare them for later success. The overarching theme in this experiment was that parents, teachers, and students from preschool to ninth grade were motivated to perform better when they were incentivized. Additionally, when students and teachers were provided with an incentive and threatened with the loss of the incentive, everyone preformed
Outline and assess the use of experiments in social psychology drawing on the cognitive social perspective and phenomenological perspective.
In this paper, I will be examining the results of an experiment where I disconnect from the Internet for 24 hours. While disconnected, I will not be allowed any access to search engines, browsers, or applications that require Internet. The only possible source of telecommunication would be through text and call without Internet. The last time where I remember living a day without Internet for 24 hours was before I owned my first ever laptop, which was back in 2007. Ever since then, my Internet usage and reliance only increased exponentially. Since I am one of the followers of the modern social construct, I would be suffering from the constant anxiousness due to the fear of missing out and the ongoing withdrawal from my habitual none-stop
The independent variables were easily controlled and there weren’t many external factors which could interfere with it. Participants completed the experiment inside an empty classroom which also helped remove any possible interference from the experimental environment. Unfortunately, there can be some criticism towards the experiment that we have conducted. Firstly, all our participants were grade 9 IB students from one school. This results in sample bias due to the fact that it cannot be correlated to general population. Unfortunately, it would be very inconvenient and difficult to conduct an experiment with adults, students and different cultures for generalized results. Participants were all friends of the same class and sat beside each other during the experiment. This may lead to possibilities of chatting and looking over at other answers. This in turn would reflect upon the idea of conformity, having participants give us dishonest results. The original Loftus and Palmer experiment was quickly criticized by Yuille and Cutshall (1986), who stated that the experiment lacks ecological validity because it is performed in an artificial environment. Also, the experiment conducted involves a scenario that participants are not physically witnessing. If participants were to witness the experiment in reality or be somewhat
Maintaining a view of all pupils at any given time can be difficult for a class teacher, especially when deciding on seating arrangements for different tasks, as the seating plans must be appropriate to enhance learning but also allow for a good view of all the children to ensure good behaviour management. Wheldall and Lam (1987) suggest that children are better seated in rows than in groups as this allows for the teacher to have a good view of the entire class and the pupils have less opportunity to misbehave. However, this does not consider the nature of the task, as sitting in row discourages group talk and also limits the number of other children each child will have the opportunity to communicate with in any given lesson. This may
