This volume describes advances in the theory of cognitive dissonance, from its origination in 1954 to the present day.

Leon Festinger’s 1957 A Theory of Cognitive Dissonance is a key text in the history of psychology – one that made its author one of the most influential social psychologists of his time. It is also a prime example of how creative thinking and problem solving skills can come together to produce work that changes the way people look at questions for good. Strong creative thinkers are able to look at things from a new perspective, often to the point of challenging the very frames in which those around them see things. Festinger was such a creative thinker, leading what came to be known as the “cognitive revolution” in social psychology. When Festinger was carrying out his research, the dominant school of thought – behaviorism – focused on outward behaviors and their effects. Festinger, however, turned his attention elsewhere, looking at “cognition:” the mental processes behind behaviors. In the case of “cognitive dissonance”, for example, he hypothesized that apparently incomprehensible or illogical behaviors might be caused by a cognitive drive away from dissonance, or internal contradiction. This perspective, however, raised a problem: how to examine and test out cognitive processes. Festinger’s book records the results of the psychological experiments he designed to solve that problem. The results helped prove the existence for what is now a fundamental theory in social psychology.

Tell any smoker that his habit is unhealthy, and he most likely will agree. What mental process does a person go through when he or she continues to do something unhealthy? When an honest person tells a "white lie," what happens to his or her sense of integrity? If someone must choose between two equally attractive options, why does one's value judgement of the options change after the choice has been made? In 1954 Dr. Leon Festinger drafted a version of a theory describing the psychological phenomenon that occurs in these situations. He called it cognitive dissonance: the feeling of psychological discomfort produced by the combined presence of two thoughts that do not follow from one another. Festinger proposed that the greater the discomfort, the greater the desire to reduce the dissonance of the two cognitive elements. The elegance of this theory has inspired psychologists over the past four decades. Cognitive Dissonance: Perspectives on a Pivotal Theory in Social Psychology documents the on-going research and debate provoked by this influential theory.

Published in 1976, Perspectives on Cognitive Dissonance is a valuable contribution to the field of Social Psychology.

Consumers’ beliefs and attitudes towards online sales significantly influence buying behavior on the internet. However, the impact of these thoughts and beliefs on the decision to make an online purchase is not direct. It can be moderated by the emotions experienced while browsing an e-commerce website. Impulse buying in particular is influenced by a number of factors, for example how stimulating the e-shopping platform is, and how easy it is to click on the cart a certain product, for instance a smartphone. But what happens after an online impulse buy is made? Often the customer can regret the purchase and in the throes of anxiety, look for reasons to justify the choices made. Consumer behaviour scholars and pyschologists call this phenomenon cognitive dissonance, and certain individuals are more sensitive than others in developing this than others. This book offers a deep investigation around online impulse buying and subsequent cognitive dissonance. Specifically, the authors present a research case study of a group of millenials who are shopping for smartphones to study whether an initial positive state can reduce the onset of cognitive dissonance in consumers. Based on substantial research and a sample of 212 impulsive millennial buyers, the book provides a comprehensive, but simple and synthetic framework of impulse buying, cognitive dissonance and positive affect state, highlighting their relationships.

Looks at the different ways in which emotions influence beliefs.
