Most people have biases, however some people are more bias than others, but people have their own biases whether they are aware or not. People prefer to confirm why they are right and they want to convince others by providing reasoning and evidences. For instance, researchers often use confirmation biases when they began an experiment. More simply, researchers often do studies on topics they have some background information on, because they want to confirm their beliefs. According to Raymond S. Nickerson (1998), author and researcher of Confirmation Bias: A Ubiquitous Phenomenon in Many Guises believes confirmation bias occurs when one is attempting to find or understand evidences they often seeking information that will confirm beliefs that …show more content…
C. Wason was interested in confirmation bias, because he wanted to see if participants would make an assumption and use evidence and reasoning to confirm their bias.Wason conducted an experiments with twenty-nine undergraduate psychology students. The participants included seventeen men and twelve women. Wason’s procedures for his experiment included college participants that made educated guesses about a rule that can be confirmed based off three numbers that he presented on a record sheet. The college participants were able to uncover the rule by recording numbers on their sheet that could pertain to the rule. After participants recorded their guesses of a possible rule, they were informed if their guesses confirmed or disconfirmed to the actual rule. Participants were given unlimited guesses, so they can uncover the actual rule. During the experiment, Wason discovered that participants did statistically better when they made eliminative guesses, than participants that decided to make enumerative guesses. Wason conforms the rule and provides his reasoning with statistics, so there was a statistical significance. Others have followed Wason and conducted the similar studies, but they made their own changes to the experiment. For instance, Wason verbally informed participants if their guesses conformed to the rule. However, Michael E. Gorman and Margaret E.Gorman wrote Y or N, which indicated if the participants guesses conformed to the rule. More simply, Gorman and …show more content…
For instance, Wason only had one experimental group, which allowed participants to make guesses to uncover the rule. While, Gorman and Gorman had more experimental groups that included participants that were disconfirmatory, confirmatory, and did not have a strategy when they made guesses about the rule. Gorman and Gorman added additional groups and manipulations to their experiment to examine techniques that participants will use based off the information they were given. They hoped to find how participants number of guesses varied based on the information they had, and the techniques they used. During their experiment, they discovered participants that used disconfirmatory as a techniques had more correct rules, than participants who were confirmatory or did not have a strategy. Gorman and Gorman experiment was not the same as Rossi, Caverni, and Girotto. For instance, Gorman and Gorman ended the experiment by informing participants of the correct, while Sandrine Rossi , Jean Paul Caverni and Vittorio Girotto ended the experiment when the right rule was guessed. According to Rossi, Caverni, and Girotto (2001), authors and researchers of Hypothesis Testing in a Rule Discovery Problem: When a Focused Procedure is Effective, states “if they announced the correct rule, the experiment ended” (p.265). Rossi, Caverni, and Girotto allowed participants to make guesses, until they knew the correct
According to Milgram, after completing the experiment, all of his subjects were informed of its true purpose, which was to find out how much pain the average person would inflict on another person when placed under authority (Milgram 78). Therefore, as Gary Sturt, author of “Behavioral Study of Obedience” states, all of the subjects were participating in an experiment without their full consent being offered to the experiment holders (Sturt). Additionally, most of the subjects were affected by the stressful nature of the experiment. A debriefing session after their completion of Milgram’s experiment was held for all of the subjects; however, as Susan Krauss Whitbourne Ph.D., author of "The Secrets Behind Psychology 's Most Famous Experiment," states, there is a “lack of proper attention given to the phase of the experiment called ‘debriefing’” (Whitbourne). Saul McLeod, author of “The Milgram Experiment,” further and more effectively explains Milgram’s attempt of ensuring the subjects’ well-being. McLeod claims that in addition to debriefing sessions after the conclusion of the experiment, all subjects were “followed up after a period of time to ensure that they came to no harm” (McLeod). Although mentioned briefly, an effective portrayal of Milgram’s debriefing sessions is not offered through his text. As Baumrind points out in her essay, the
In the second experiment, Perillo did the same format at the experiment above however, instead of false incriminating evidence they used a bluff. The bluff was added after the computer crashed by saying they have “recorded all of their key strokes” and have a camera in the back recording” (Perillo, Kassin). The thought that the key stroke calculator and the camera would help prove them innocent, the majority of the participants confessed “22 of 38 (57.9%)” (Perillo, Kassin). The third experiment involved a sort of game show where a group of the participants were put in a room and had to answer questions. They were told if they cheated that it would be very bad for their scholar record. One group was put in a room and had no one attempt have them cheat. The other room used a confederate to act like they don’t know the answers and ask for help, whether the person answered or not was what was recorded. At the end the ones who didn’t respond were let go and the once who even responded with no were confronted and accused of cheating. They said they had a camera in the back and room recording the session and knew
When it comes to the observation part of forming the experiment as well as after the experiment was done, a lot of groups observed the same things. The most significant observations were we observed the
When and why do you think the subject in the experiment began to "second guess" himself?
Furthermore, the authors aim to unfold the scientific logic of their analysis of the effects of hidden biases so people will be “better able to achieve the alignment,” between their behavior and intentions (Banaji and Greenwald, 2013) preface
Stanley Milgram and Philip Zimbardo Conducted an experiment to test whether people would react differently under certain circumstances than they would normally react. They tested this by having a stranger administer an electrical shock to an unknown person. The stranger wouldn’t be able to see the subject getting shocked but would be able to hear them. The experimenter went through a number of trials asking the subject questions, and for every question they got wrong the shock would increase one interval. The stranger administering the shock would increase the intensity of the shock each time they were told to do so. They got to a point where they would be administering a lethal shock to the subject just because they were told to do so. In
Milgram's study lacked experimental realism because the participants could not have believed in the setup. Orme and Holland said that surely Milgram should have been the confederate receiving the shocks, since this would have made it far easier to believe in the setup. However Rosenhan said that 70% of the participants did believe in the whole setup, but there is 30% who did not. Orme and Holland also said that, obedience is a demand characteristic since the participants are required to obey experimental orders. Therefore it made it difficult for the participants to believe in the setup of the experiment.
Since Slater et al. were replicating Milgram’s study of obedience, their setup was also identical. The advantage of this was that the were no variances slipping into the experiment thus ensuring that the findings were solid and pure of contamination due to minor changes; The results were genuine findings into human behaviour.
n hypothesis of the experiment is that the group containing four members will perform better than the group containing two members. This is the foundation from which we have conducted our experiment.
Loftus and Palmer conducted their investigation in a lab and so were able to establish a strong causal link between the verb used and the answers given and be sure that most of the other variables were controlled. However there are problems using a lab, one being it does not accurately represent real life and so lacks eternal validity; this is because in a real incident the eyewitness would be experiencing emotions that also affect the reliability of their recall as well as having no warning as to when the incident would happen and when it would stop, whereas, in a lab the participants knew they were going to witness a video and how long it would last.
Growing up in a very accepting and forward home, I always found myself to be free of most bias. Having been the target of some racial prejudice in the past, I always told myself that I would make sure nobody else had to feel the same way. While this may be a great way to think, it really only covers the fact that you will not have any explicit bias. What I have realized during the course of this class is that implicit bias often has a much stronger effect on us than we might think, and even the most conscious people can be affected.
The Milgram experiment is probably one of the most well known experiments in Psychology. The reason being is because its participants were not told what was really occurring in the experiment. After the experiment was over, the participants were mentally and emotionally affected. Later, a cognitive psychologist, George Miller described Milgram’s experiments, together with Zimbardo’s Prison Experiment, as “being ideal for public consumption of psychological research” (Blass, 2002). And indeed, Milgram’s studies, as Zimbardo’s, are clearly meant to be spread to a broad audience, the moral and preventative objectives permeating the experiments from their very outset (Stavrakis, 2007).. In this paper, I will explore how experiments such as Milgram and Zimbardo’s, as well as the Tuskeegee Syphilis Experiment, changed the way experiments are conducted today because of the formation of the Institutional Review Board (IRB).
The experiments were quite simple, in that there was a seemingly harmless task to be performed, and the participants were instructed to choose the estimation of the lengths of a line when compared to two ...
Could Previous Experiences Help Identify and Overcome Biases? A common cognitive error is the correspondence bias, also know as the Fundamental Attribution Error. The correspondence bias is a phenomenon in which a person will attribute another’s actions as a result of their disposition and personality, not factoring in the effect the social and physical environment has upon one’s actions. This bias affects not only the current judgment, but it also attributes to stereotypes about certain people and groups.
In order for an experiment to be considered a true experimental design, the design must fit specific criteria. The researcher must have a hypothesis for a cause and effect relationship between variables, the treatment group, the control group, random selection for the treatment group, and random assignment for the control group. In a simple experiment, the researcher forms two groups that are similar or equivalent, through probability, to each other in every way possible appropriate to the concept of experiment. The treatment group receives the procedure for the experiment and the control group does not. Therefore, the only difference between the groups will be that one group receives the treatment for the experiment and one group does note. After the experiment is conducted the researcher analysis the results in both groups.
