Illusory Superiority
In social psychology, illusory superiority is a cognitive bias wherein people overestimate their own qualities and abilities compared to others. Illusory superiority is one of many positive illusions, relating to the self, that are evident in the study of intelligence, the effective performance of tasks and tests, and the possession of desirable personal characteristics and personality traits. Overestimation of abilities compared to an objective measure is known as the ''overconfidence effect''. The term "illusory superiority" was first used by the researchers Van Yperen and Buunk, in 1991. The phenomenon is also known as the above-average effect, the superiority bias, the leniency error, the sense of relative superiority, the ''primus inter pares'' effect, and the Lake Wobegon effect, named after the fictional town where all the children are above average. The Dunning-Kruger effect is a form of illusory superiority shown by people on a task where their level of skill is low ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Psychology
Social psychology is the methodical study of how thoughts, feelings, and behaviors are influenced by the actual, imagined, or implied presence of others. Although studying many of the same substantive topics as its counterpart in the field of sociology, psychological social psychology places more emphasis on the individual, rather than society; the influence of social structure and culture on individual outcomes, such as personality, behavior, and one's position in social hierarchies. Social psychologists typically explain human behavior as a result of the relationship between mental states and social situations, studying the social conditions under which thoughts, feelings, and behaviors occur, and how these variables influence social interactions. History 19th century In the 19th century, social psychology began to emerge from the larger field of psychology. At the time, many psychologists were concerned with developing concrete explanations for the different aspe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overconfidence
The overconfidence effect is a well-established bias in which a person's subjective ''confidence'' in their judgments is reliably greater than the objective ''accuracy'' of those judgments, especially when confidence is relatively high. Overconfidence is one example of a miscalibration of subjective probabilities. Throughout the research literature, overconfidence has been defined in three distinct ways: (1) ''overestimation'' of one's actual performance; (2) ''overplacement'' of one's performance relative to others; and (3) ''overprecision'' in expressing unwarranted certainty in the accuracy of one's beliefs. The most common way in which overconfidence has been studied is by asking people how confident they are of specific beliefs they hold or answers they provide. The data show that confidence systematically exceeds accuracy, implying people are more sure that they are correct than they deserve to be. If human confidence had perfect calibration, judgments with 100% confidence w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Median
The median of a set of numbers is the value separating the higher half from the lower half of a Sample (statistics), data sample, a statistical population, population, or a probability distribution. For a data set, it may be thought of as the “middle" value. The basic feature of the median in describing data compared to the Arithmetic mean, mean (often simply described as the "average") is that it is not Skewness, skewed by a small proportion of extremely large or small values, and therefore provides a better representation of the center. Median income, for example, may be a better way to describe the center of the income distribution because increases in the largest incomes alone have no effect on the median. For this reason, the median is of central importance in robust statistics. Median is a 2-quantile; it is the value that partitions a set into two equal parts. Finite set of numbers The median of a finite list of numbers is the "middle" number, when those numbers are liste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skewed
In probability theory and statistics, skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean. The skewness value can be positive, zero, negative, or undefined. For a unimodal distribution (a distribution with a single peak), negative skew commonly indicates that the ''tail'' is on the left side of the distribution, and positive skew indicates that the tail is on the right. In cases where one tail is long but the other tail is fat, skewness does not obey a simple rule. For example, a zero value in skewness means that the tails on both sides of the mean balance out overall; this is the case for a symmetric distribution but can also be true for an asymmetric distribution where one tail is long and thin, and the other is short but fat. Thus, the judgement on the symmetry of a given distribution by using only its skewness is risky; the distribution shape must be taken into account. Introduction Consider the two d ...

Mean
A mean is a quantity representing the "center" of a collection of numbers and is intermediate to the extreme values of the set of numbers. There are several kinds of means (or "measures of central tendency") in mathematics, especially in statistics. Each attempts to summarize or typify a given group of data, illustrating the magnitude and sign of the data set. Which of these measures is most illuminating depends on what is being measured, and on context and purpose. The ''arithmetic mean'', also known as "arithmetic average", is the sum of the values divided by the number of values. The arithmetic mean of a set of numbers ''x''1, ''x''2, ..., x''n'' is typically denoted using an overhead bar, \bar. If the numbers are from observing a sample of a larger group, the arithmetic mean is termed the '' sample mean'' (\bar) to distinguish it from the group mean (or expected value) of the underlying distribution, denoted \mu or \mu_x.

Confidence
Confidence is the feeling of belief or trust that a person or thing is reliable. * * * Self-confidence is trust in oneself. Self-confidence involves a positive belief that one can generally accomplish what one wishes to do in the future. Self-confidence is not the same as self-esteem, which is an evaluation of one's worth. Self-confidence is related to self-efficacy—belief in one's ability to accomplish a specific task or goal. Confidence can be a self-fulfilling prophecy, as those without it may fail because they lack it, and those with it may succeed because they have it rather than because of an innate ability or skill. History Ideas about the causes and effects of self-confidence have appeared in English-language publications describing characteristics of a sacrilegious attitude toward God, the character of the British empire, and the culture of colonial-era American society. In 1890, the philosopher William James in his '' Principles of Psychology'' wrote, "Belie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Popularity
In sociology, popularity is how much a person, idea, place, item or other concept is either liked or accorded status by other people. Liking can be due to reciprocal liking, interpersonal attraction, and similar factors. Social status can be due to Dominance (ethology), dominance, superiority, and similar factors. For example, a kind person may be considered likable and therefore more popular than another person, and a wealthy person may be considered superior (hierarchy), superior and therefore more popular than another person. There are two primary types of interpersonal popularity: perceived and sociometric. Perceived popularity is measured by asking people who the most popular or socially important people in their social group are. Sociometric popularity is measured by objectively measuring the number of connections a person has to others in the group. A person can have high perceived popularity without having high sociometric popularity, and ''vice versa''. According to p ...

Job Performance
Job performance assesses whether a person performs a job well. Job performance, studied academically as part of industrial and organizational psychology, also forms a part of human resources management. Performance is an important criterion for organizational outcomes and success. John P. Campbell describes job performance as an individual-level variable, or something a single person does. This differentiates it from more encompassing constructs such as organizational performance or national performance, which are higher-level variables. Features There are several key features to Campbell's conceptualization of job performance which help clarify what job performance means. Outcomes First, Campbell defines performance as behavior, which is something done by an employee. This concept differentiates performance from outcomes. Outcomes result partially from an individual's performance, but they are also the result of other influences. In other words, there are more factors that ...

Anterior Cingulate Cortex
In human brains, the anterior cingulate cortex (ACC) is the frontal part of the cingulate cortex that resembles a "collar" surrounding the frontal part of the corpus callosum. It consists of Brodmann areas 24, 32, and 33. It is involved in certain higher-level functions, such as attention allocation, reward anticipation, decision-making, impulse control (e.g. performance monitoring and error detection), and emotion. Some research calls it the anterior midcingulate cortex (aMCC). Anatomy The anterior cingulate cortex can be divided anatomically based on cognitive (dorsal), and emotional ( ventral) components. The dorsal part of the ACC is connected with the prefrontal cortex and parietal cortex, as well as the motor system and the frontal eye fields, making it a central station for processing top-down and bottom-up stimuli and assigning appropriate control to other areas in the brain. By contrast, the ventral part of the ACC is connected with the amygdala, nucleu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orbitofrontal Cortex
The orbitofrontal cortex (OFC) is a prefrontal cortex region in the frontal lobes of the brain which is involved in the cognitive process of decision-making. In non-human primates it consists of the association cortex areas Brodmann area 11, 12 and 13; in humans it consists of Brodmann area 10, 11 and 47. The OFC is functionally related to the ventromedial prefrontal cortex.Phillips, LH., MacPherson, SE. & Della Sala, S. (2002). 'Age, cognition and emotion: the role of anatomical segregation in the frontal lobes: the role of anatomical segregation in the frontal lobes'. in J Grafman (ed.), Handbook of Neuropsychology: the frontal lobes. Elsevier Science, Amsterdam, pp. 73-98. Therefore, the region is distinguished due to the distinct neural connections and the distinct functions it performs.Barbas H, Ghashghaei H, Rempel-Clower N, Xiao D (2002) Anatomic basis of functional specialization in prefrontal cortices in primates.

Journal Of Experimental Psychology
The ''Journal of Experimental Psychology'' was a bimonthly peer-reviewed academic journal published by American Psychological Association. Established in 1916, it became the association's largest and most prestigious journal by the mid-1970s, when dissatisfaction with publication lag led the organization to restructure the journal. Beginning in 1975, it was split into four independently edited and distributed successor journals, with an additional successor journal being added in 1995. History The first issue was published by the Psychological Review Company, Princeton, New Jersey The Municipality of Princeton is a Borough (New Jersey), borough in Mercer County, New Jersey, United States. It was established on January 1, 2013, through the consolidation of the Borough of Princeton, New Jersey, Borough of Princeton and Pri ....

Statistical Mean
In mathematics and statistics, the arithmetic mean ( ), arithmetic average, or just the ''mean'' or ''average'' is the sum of a collection of numbers divided by the count of numbers in the collection. The collection is often a set of results from an experiment, an observational study, or a survey. The term "arithmetic mean" is preferred in some contexts in mathematics and statistics because it helps to distinguish it from other types of means, such as geometric and harmonic. Arithmetic means are also frequently used in economics, anthropology, history, and almost every other academic field to some extent. For example, per capita income is the arithmetic average of the income of a nation's population. While the arithmetic mean is often used to report central tendencies, it is not a robust statistic: it is greatly influenced by outliers (values much larger or smaller than most others). For skewed distributions, such as the distribution of income for which a few people's incomes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
