“Suppose you had kids who were normally healthy, psychologically and physically, and they knew they would be going into a prison-like environment and that some of their civil rights would be sacrificed. Would those good people, put in that bad, evil place – would their goodness triumph?” Zimbargo
Cognitive dissonance is the unconfortable feeling or stress caused by holding two contradictory ideas simultaneously. The theory of cognitive dissonance proposes that people have a fundamental cognitive drive to reduce this dissonance by modifying an existing belief, or rejecting one of the contradictory ideas.
In 1971, psychologist Philip Zimbardo and his colleagues set out to create an experiment that looked at the impact of becoming a prisoner or prison guard. Zambardo, a former classmate of Stanley Milgram (Obedience experiment) was interested in expanding upon Milgram’s research. He wanted to further investigate the impact of situational variables on human behavior. That led Zimbardo to explore the psychological effect of becoming a prison guard or prisoner. The experiment took place in Stanford University, California, and there was 24 male participants. The participants we predominantly white and middle-class. There were originally 70 volunteers, but Zimbardo picked the 24 “most psychologically stable and healthy”. The “prison” was mock, and constructed in the basement of the Psychology department in Stanford University. Participants were paid for their time ($15 a day).
The simulated prison included three six by nine foot prison cells. Each cell held three prisoners and included three cots. Other rooms across from the cells were

Cognitive Dissonance Theory

...Cognitive Dissonance Theory I know it is bad for me. I have read about, heard of and listened to the side effects of this taboo beverage. Yet, I am always unable to resist the promise of instant gratification that can be mine simply by breaking the seal of its carbonated packaging. My eyes linger on the variety of healthier options that lay behind the sliding glass doors; however, my fingers are already tightly grasped around the silver label of a twenty ounce Diet Coke. Each refreshing sip fills my head with depressing logic that can only be drowned with more fizzy brown bubbles. The chemicals in Diet Coke have been shown to cause cancer in lab rats. The sugar substitutes found in Diet Coke increase sugar cravings negating the “diet” value. Habitual Diet Coke drinkers are significantly heavier than those who indulge in the occasional full calorie version. Diet Coke is detrimental to bone health… The warnings echo loudly in my head almost as loud as my endless self chastising. Why do I force myself to eat fresh fruits and vegetables when what I really want is Chipotle? Why do I walk to class when I’m offered a free ride? Why do I punish myself with healthy activities when I am killing my body with Diet Coke anyway? I curse the investigative reporter who first divulged Diet Coke’s dirty little secret as I hand over $1.35 for my second drink of the day. I would even feel guilty if the woman in front of me had not just bought cigarettes. Cognitive dissonance is a feeling of...

An Examination of Festingers Cognitive Dissonance Theory and Notable Modifactions

...An Examination of Festingers Cognitive Dissonance Theory and Notable Modifications Sometimes the greatest test of a theory is its longevity. Over time, some theories will be disproved, some will be modified, and some will become the basis for a whole new group of theories. Leon Festinger’s theory of cognitive dissonance has stood up to challenge for over forty years, and is considered by many to be the single most important theory of social psychology. Though there have been modifications to the theory after many recreations and simulations of the original 1957 experiment, few have been able to really disqualify Festinger’s findings. It would be safe to say that many people don’t even have a full grasp of the incredible implications that Festinger’s research and experiments have towards the self-concept and behavior, myself not excluded. The actual definition of cognitive dissonance is almost too simple: an unpleasant feeling that arises from the contradiction of belief and action. Festinger, however, went on to find that dissonance would in fact change attitudes over time, helping people to justify their behavior when they know it is clearly wrong. Festinger’s original experiment was a simple procedure. Have someone perform a tedious task for a while, then inform the subject that the experiment is finished, but that they could be of assistance with the rest of the experiment as a research assistant. Festinger explained that his regular assistant was...

Cognitive Dissonance Theory

...The history of national origin and racial exclusion in U.S. immigration laws serves as a lens into this nation's soul. There is no better body of law to illustrate the close nexus between race and class than U.S. immigration law and its enforcement. The United States also has a long history of restricting (if not outright excluding) entry of certain racial minority groups into the country. Transference of hate and displacement of frustration from one racial minority to another explain much in the heated racial dynamics of the twentieth century. Cognitive dissonance theory teaches us how the nation can be so harsh to noncitizens of color while claiming that racism is dead in America. . Immigration law expressly defines who can and cannot enter...

Examples Of Cognitive Dissonance Theory

...The cognitive dissonance theory states that inconsistency between attitudes and behaviors produces psychological discomfort, leading people to change either their attitude or their behavior in order to restore balance. After taking my first psych class, I started to interpret everything I did to be a product of some psychological phenomenon. So, naturally, when life got in the way of following my rules religiously, I diagnosed myself as cognitively dissonant every time what I did diverged from what I...

Issue Analysis: Cognitive Dissonance

...Issue Analysis: Cognitive Dissonance PSYCH/555 April 22, 2013 Dr. Keisha Anthony Issue Analysis: Cognitive Dissonance “Festinger's (1957) cognitive dissonance theory suggests that we have an inner drive to hold all our attitudes and beliefs in harmony and avoid disharmony (or dissonance)” (McLeod, 2008). Issue 5: Does Cognitive Dissonance Explain Why Behavior Can Change Attitudes debates the cognitive dissonance theory with one of the authors challenging the theory by claiming that self-perception is a better explanation as to why people behave differently once they have acted outside of their norm as most people try to find some sort of consistency between their actions and their attitudes. Consonant and dissonant cognitions both affect the attitude on opposite ends of a spectrum. As with consonant cognitions the behavior matches the attitude and with dissonant cognitions have behaviors that conflict with their attitudes. One of the most powerful influences on attitude change is the motivation of people to maintain that consistency between their attitudes and behaviors. Although the cognitive dissonance theory is studied and utilized by psychologists all over the world, there are some who reject this theory and believe that self-perception is what enables people to decide on their attitudes, emotions, and behaviors because they are able to cast judgment upon themselves based on their behavior in different situations. Summary of both Arguments in Issue 5 Festinger...

Cognitive Dissonance In Lord Of The Flies, By William Golding

...In 1957, scientist Leon Festinger proposed “Cognitive Dissonance Theory”, which states that a powerful motive to maintain cognitive consistency can give rise to irrational and sometimes maladaptive behavior. Cognitive Dissonance affects the person's ability to make decisions and allows for them to escape the guilt. Lord of the Flies is an example of “Cognitive Dissonance” in humans, in that both the novel and the psychological theory illustrate the premise that humans tend to justify their actions by lying to themselves. William Golding’s book Lord of the Flies is about a group of boys whose plane crashes, leaving them stranded on an island. Throughout the book the boys lose their sanity and begin to fight. As the boys struggle to find a balance in power between Ralph, a young boy who was originally elected as leader, and Jack, a wild, ill tempered, boy who challenges Ralph; the two shy intelligent boys, Piggy and Simon, are ostracised and viewed as unreliable and suspicious.Subsequently Simon is brutally murdered after trying to alert the group that the monster they have feared is really just a dead military parachutist (Golding, 138-139). Later Piggy also dies as an effect of Roger, Jack’s second in command, crushing him with a boulder (Golding, 164-165). “Cognitive Dissonance Theory” is the theory that humans justify our actions by...

Cognitive Dissonance

...Cognitive Dissonance Theory According to Myers (2010), cognitive dissonance is a situation that arises bringing tension from ides and actions upon each other. One of the main purposes of cognitive dissonance theory is to change the individual’s attitudes and hold them accountable for their actions. This theory believe that if a person or individuals could take on the responsibility of their negative actions, a change is more likely to happen in their behavior (Cheng & Hsu, 2012). On the other hand, if they are not willing to accept the consequence that comes with the action, the behavior will continue. A situation, such as second-degree murder, Zimmerman could have used cognitive dissonance theory to rationalize his behavior. Murder is a crime, and any one who commits such crime realize that it is not morally correct and the action will have consequences. Zimmerman claim he shot Martin in self-defense, and was acquitted of his charges. In this situation, murder was not understandable or justified. He was thinking about the welfare of himself and no the welfare of Trayvon Martin, an innocent child. Zimmerman believed that he was protecting his community and by all means possible. A person in his situation felt that he needed to do whatever in order change the situation. The decision of Zimmerman did not make it better for either family, his actions made the matter worse. When a person does not rationalize his or her thoughts, his or her behaviors will result inappropriately...

...Attitude Theories Patricia Saylor Strayer University Online Prof. Robin Oatis-Ballew May 6, 2012 Cognitive dissonance was fist examined by Leon Festinger, this arose from the observations he made of a cult whom believed that the earth would soon be destroyed by a flood. Members that had been faithful to the cult had to give up their homes and jobs to come and work for the cult. This came about after the fact the earth was not destroyed by the flood. The faithful members of the cult were ashamed and felt like they had made fools of themselves for believing that something like this was about to happen. According to cognitive dissonance theory, there is a tendency for individuals to seek consistency among their cognitions (beliefs, opinions). When there is an inconsistency between attitudes or behaviors (dissonance), something must change to eliminate the dissonance. In the case of a discrepancy between attitudes and behavior, it is most likely that the attitude will change to accommodate the behavior. This is the feeling of uncomfortable tension which comes from holding two conflicting thoughts in the mind at the same time. Dissonance increases with the importance of the subject to us, how strongly the dissonant thoughts conflict, our inability to rationalize and explain away the conflict. Two factors affect the strength of the dissonance: the number of dissonant beliefs, and the importance attached to each belief. There are three ways to...

Partner Baggage

...factors are the equity theory, attachment styles, when to reveal and when to conceal, and the cognitive dissonance theory. These factors play a very big role in relationship baggage and they are all discussed extensively through many scholarly articles. The following articles illustrate the research done on the topic of partner baggage as it pertains to these particular factors in romantic relationships. Keywords: partner baggage, relational uncertainty, relational turbulence, dark side, interpersonal relationships According to an article by Sidelinger and Booth-Butterfield, partner baggage is defined as, “negative attributes and situations which create obstacles to optimal relationship outcomes” (Sidelinger & Booth-Butterfield, 2009, p. 405). That is just a really fun way of saying that one or both participants of a relationship have some issues that could be potentially detrimental to the relationship. Partner baggage is very common in most relationships, 69% of couples reported this about partner baggage (Sidelinger & Booth-Butterfield, 2009, p. 414). There is a lot of ambiguity in relationships to begin with (Spitzberg & Cupach, 2011, p. 31), but partner baggage adds another element of relational uncertainty. To understand partner baggage in relationships better, we will discuss this through the equity theory, attachment styles, when to reveal and when to conceal, and cognitive dissonance.

Cognitive Dissonance: Abortion

...Cognitive Dissonance: Abortion Individuals are social by nature and can be influenced by various factors when making choices. An individual is capable of feeling the pressure from family, peers, and community. An individual may also believe that doing something like cheating is acceptable if in the end one obtains the desire result. An individual may experience an internal exchange of ideas and problems when making a decision how to find the way through a complicated decision. Individuals may also negotiate and barter with their divine beliefs to feel at ease when making a decision to behave in an unpleasant and moral way. Cognitive dissonance theory is extremely active in this stage of disagreement, when an individual is in a state of moral conflict the theory is applied to regulate, find a balance, and to have peace of mind (Benoit, 2012). Individuals come upon countless situations throughout life when a complicated decision must be made; often times a person will even go against spiritual and moral beliefs when sensing external pressure. Moral and cognitive maturity along with a strong sense of self will assist on a logical decision. Identify the Situation Individual Consciously Made in a Behavior that Violated Cognitions Since the beginning of time, man expands all his mental facilities and physical limitations to discover the meaning of life and search to discover, when life begins. Physicians, scholars, theologians, and lay people have spent...

Opening Skinner's Box Analysis

...In the 5th Chapter of Opening Skinner’s Box, Lauren Slater explores Festinger’s cognitive dissonance theory. She defines the theory as an explanation of the compulsion to “… bring your beliefs back into alignment with your actions, so as to reduce the dissonance between your self-concept and your questionable behavior” (Slater). She focuses on a classical version of the theory, and consequently becomes fixated on a woman named Linda Santo and her daughter, who she feels perfectly embody Festinger’s theory. In her quest to understand how cognitive dissonance is applied in their lives, she treats Santo with disrespect for her faith and actively tries to show her the flaws in a harmless belief that she has built her life around. Her blatant disregard...

Cognitive Dissonance

...Cognitive Dissonance Theory Introduction: “Knowing that drinking alcohol is harmful, I like to drink more.” Cognitive dissonance refers to a situation conflicting attitudes, beliefs or behaviors. The above example depicts a conflicting cognition where I know that drinking is harmful to my health but I like to drink more. This is cognitive dissonance. A story about a fox that tried in vain to reach a cluster of grapes that dangled from a vine above his head. The fox leapt high to grasp the grapes, but the delicious-looking fruit remained just out of reach of his snapping jaws. After a few attempts the fox gave up and said to himself, ‘‘These grapes are sour, and if I had some I would not eat them." The fox changed his attitude to fit his behavior. Leon Festinger (1957) described cognitive dissonance as a psychologically uncomfortable state that motivates a person to reduce that dissonance. According to the theory, there is a tendency for individual to seek consistency among their cognitive (i.e. beliefs and opinions). When there is some kind of discrepancies occurring between attitudes or behaviors, something must be changed to rule out the dissonance. Thesis Statement: Cognitive Dissonance is a state of mind involving ones attitudes, beliefs, or behaviors. People feel discomfort leading to an alteration in one of the attitudes, beliefs, or behaviors to reduce discomfort and restore balance. Body Paragraph: According to Festinger, people consider many cognitions...
