Effort Heuristic
{{refimprove, date = October 2007 The effort heuristic is a mental rule of thumb in which the quality or worth of an object is determined from the perceived amount of effort that went into producing that object. In brief, the effort heuristic follows a tendency to judge objects that took a longer time to produce to be of higher value.Kruger, J., Wirtz, D., Boven, L., & Altermatt, T. (2004). The effort heuristic. Journal of Experimental Social Psychology, 40, 91-98. The more effort invested in an object, the better it is deemed to be. This is especially true in situations where value is difficult to assess or the evaluator lacks expertise in the appraisement of an item. People use whatever information is available to them and effort is thought to generally be a reliable indicator of quality. An example of this would be the comparison of $100 earned, and $100 found. If someone finds $100 they are more inclined to go spend it on a whim, but if that $100 is part of a hard-earned payc ...

Rule Of Thumb
In English, the phrase ''rule of thumb'' refers to an approximate method for doing something, based on practical experience rather than theory. This usage of the phrase can be traced back to the 17th century and has been associated with various trades where quantities were measured by comparison to the width or length of a thumb. A modern folk etymology holds that the phrase is derived from the maximum width of a stick allowed for wife-beating under English common law, but no such law ever existed. This belief may have originated in a rumored statement by 18th-century judge Sir Francis Buller that a man may beat his wife with a stick no wider than his thumb. The rumor produced numerous jokes and satirical cartoons at Buller's expense, but there is no record that he made such a statement. English jurist Sir William Blackstone wrote in his ''Commentaries on the Laws of England'' of an "old law" that once allowed "moderate" beatings by husbands, but he did not mention thumbs or any ...

Heuristics In Judgment And Decision Making
Heuristics is the process by which humans use mental short cuts to arrive at decisions. Heuristics are simple strategies that humans, animals, organizations, and even machines use to quickly form judgments, make decisions, and find solutions to complex problems. Often this involves focusing on the most relevant aspects of a problem or situation to formulate a solution. While heuristic processes are used to find the answers and solutions that are ''most'' likely to work or be correct, they are not always right or the most accurate. Judgments and decisions based on heuristics are simply good enough to satisfy a pressing need in situations of uncertainty, where information is incomplete. In that sense they can differ from answers given by logic and probability. The economist and cognitive psychologist Herbert A. Simon introduced the concept of heuristics in the 1950s, suggesting there were limitations to rational decision making. In the 1970s, psychologists Amos Tversky and Daniel K ...

Cognitive Dissonance
In the field of psychology, cognitive dissonance is the perception of contradictory information, and the mental toll of it. Relevant items of information include a person's actions, feelings, ideas, beliefs, values, and things in the environment. Cognitive dissonance is typically experienced as psychological stress when persons participate in an action that goes against one or more of those things. According to this theory, when two actions or ideas are not psychologically consistent with each other, people do all in their power to change them until they become consistent. The discomfort is triggered by the person's belief clashing with new information perceived, wherein the individual tries to find a way to resolve the contradiction to reduce their discomfort.Festinger, L. (1957). ''A Theory of Cognitive Dissonance''. California: Stanford University Press. In '' When Prophecy Fails: A Social and Psychological Study of a Modern Group That Predicted the Destruction of the World'' ( ...

Effort Justification
Effort justification is an idea and paradigm in social psychology stemming from Leon Festinger's theory of cognitive dissonance. Effort justification is a person's tendency to attribute the value of an outcome they put effort into achieving as greater than the objective value of the outcome. Theory and research Cognitive dissonance theory explains changes in people's attitudes or beliefs as the result of an attempt to reduce a dissonance (discrepancy) between contradicting ideas or cognitions. In the case of effort justification, there is a dissonance between the amount of effort exerted into achieving a goal or completing a task (high effort equalling high "cost") and the subjective reward for that effort (lower than was expected for such an effort). By adjusting and increasing one's attitude or subjective value of the goal, this dissonance is resolved. One of the first and most classic examples of effort justification is Aronson and Mills's study. A group of young women who vo ...

Self-perception Theory
Self-perception theory (SPT) is an account of attitude formation developed by psychologist Daryl Bem. It asserts that people develop their attitudes (when there is no previous attitude due to a lack of experience, etc.—and the emotional response is ambiguous) by observing their own behavior and concluding what attitudes must have caused it. The theory is counterintuitive in nature, as the conventional wisdom is that attitudes determine behaviors. Furthermore, the theory suggests that people induce attitudes without accessing internal cognition and mood states. The person interprets their own overt behaviors rationally in the same way they attempt to explain others' behaviors. Bem's original experiment In an attempt to decide if individuals induce their attitudes as observers without accessing their internal states, Bem used interpersonal simulations, in which an "observer-participant" is given a detailed description of one condition of a cognitive dissonance experiment.

Availability Heuristic
The availability heuristic, also known as availability bias, is a mental shortcut that relies on immediate examples that come to a given person's mind when evaluating a specific topic, concept, method, or decision. This heuristic, operating on the notion that, if something can be recalled, it must be important, or at least more important than alternative solutions not as readily recalled, is inherently biased toward recently acquired information. The mental availability of an action's consequences is positively related to those consequences' perceived magnitude. In other words, the easier it is to recall the consequences of something, the greater those consequences are often perceived to be. Most notably, people often rely on the content of their recall if its implications are not called into question by the difficulty they have in recalling it. Overview and history In the late 1960s and early 1970s, Amos Tversky and Daniel Kahneman began work on a series of papers examining "heur ...

Affect Heuristic
The affect heuristic is a heuristic, a mental shortcut that allows people to make decisions and solve problems quickly and efficiently, in which current emotion—fear, pleasure, surprise, etc.—influences decisions. In other words, it is a type of heuristic in which emotional response, or " affect" in psychological terms, plays a lead role. It is a subconscious process that shortens the decision-making process and allows people to function without having to complete an extensive search for information. It is shorter in duration than a mood, occurring rapidly and involuntarily in response to a stimulus. Reading the words "lung cancer" usually generates an affect of dread, while reading the words "mother's love" usually generates a feeling of affection and comfort. The affect heuristic is typically used while judging the risks and benefits of something, depending on the positive or negative feelings that people associate with a stimulus. It is the equivalent of "going with your ...

Labor Theory Of Value
The labor theory of value (LTV) is a theory of value that argues that the economic value of a good or service is determined by the total amount of " socially necessary labor" required to produce it. The LTV is usually associated with Marxian economics, although it originally appeared in the theories of earlier classical economists such as Adam Smith and David Ricardo, and later in anarchist economics. Smith saw the price of a commodity in terms of the labor that the purchaser must expend to buy it, which embodies the concept of how much labor a commodity, a tool for example, can save the purchaser. The LTV is central to Marxist theory, which holds that the working class is exploited under capitalism, and dissociates price and value. However, Marx did not refer to his own theory of value as a "labour theory of value". Orthodox neoclassical economics rejects the LTV, using a theory of value based on subjective preferences. The revival in interpretation of Marx known as the also ...

Heuristics
A heuristic (; ), or heuristic technique, is any approach to problem solving or self-discovery that employs a practical method that is not guaranteed to be optimal, perfect, or rational, but is nevertheless sufficient for reaching an immediate, short-term goal or approximation. Where finding an optimal solution is impossible or impractical, heuristic methods can be used to speed up the process of finding a satisfactory solution. Heuristics can be mental shortcuts that ease the cognitive load of making a decision. Examples that employ heuristics include using trial and error, a rule of thumb or an ansatz, educated guess. Heuristics are the strategies derived from previous experiences with similar problems. These strategies depend on using readily accessible, though loosely applicable, information to control problem solving in human beings, machines and abstract issues. When an individual applies a heuristic in practice, it generally performs as expected. However it can alternati ...

Experimental Psychology
Experimental psychology refers to work done by those who apply experimental methods to psychological study and the underlying processes. Experimental psychologists employ human participants and animal subjects to study a great many topics, including (among others) sensation & perception, memory, cognition, learning, motivation, emotion; developmental processes, social psychology, and the neural substrates of all of these. History Early experimental psychology Wilhelm Wundt Experimental psychology emerged as a modern academic discipline in the 19th century when Wilhelm Wundt introduced a mathematical and experimental approach to the field. Wundt founded the first psychology laboratory in Leipzig, Germany. Other experimental psychologists, including Hermann Ebbinghaus and Edward Titchener, included introspection in their experimental methods. Charles Bell Charles Bell was a British physiologist whose main contribution to the medical and scientific c ...
