Countersignaling
Countersignaling is the behavior in which agents with the highest level of a given property invest less into proving it than individuals with a medium level of the same property. This concept is primarily useful for analyzing human behavior and thus relevant to signaling theory in economics, sociology and psychology. For example, moderately wealthy individuals may conspicuously display luxury goods to signal their status, while extremely wealthy individuals might avoid such displays altogether, relying instead on subtler cues—or none at all—because their status is already well-known or inferred from other trusted sources. Signals and signaling theory Much research is concerned with understanding what signals signalers should send to convince a receiver that they have a certain property, and what signals a receiver should be convinced by. One way of doing this is by putting money on the table just to prove that you can; someone without the property would not be able to do the ...

Signalling (economics)
Signalling (or signaling; see American and British English spelling differences#Doubled consonants, spelling differences) in contract theory is the idea that one party (the law of agency, agent) credibly conveys some information about itself to another party (the principal (commercial law), principal). Signalling was already discussed and mentioned in the seminal Theory of Games and Economic Behavior, which is considered to be the text that created the research field of game theory. Although signalling theory was initially developed by Michael Spence based on observed knowledge gaps between organisations and prospective employees, its intuitive nature led it to be adapted to many other domains, such as Human Resource Management, business, and financial markets. In Spence's job-market signaling model, (potential) employees send a signal about their ability level to the employer by acquiring education credentials. The informational value of the credential comes from the fact that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peacock
Peafowl is a common name for two bird species of the genus '' Pavo'' and one species of the closely related genus '' Afropavo'' within the tribe Pavonini of the family Phasianidae (the pheasants and their allies). Male peafowl are referred to as peacocks, and female peafowl are referred to as peahens. The two Asiatic species are the blue or Indian peafowl originally from the Indian subcontinent, and the green peafowl from Southeast Asia. The third peafowl species, the Congo peafowl, is native only to the Congo Basin. Male peafowl are known for their piercing calls and their extravagant plumage. The latter is especially prominent in the Asiatic species, which have an eye-spotted "tail" or "train" of covert feathers, which they display as part of a courtship ritual. The functions of the elaborate iridescent coloration and large "train" of peacocks have been the subject of extensive scientific debate. Charles Darwin suggested that they served to attract females, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biology
Biology is the scientific study of life and living organisms. It is a broad natural science that encompasses a wide range of fields and unifying principles that explain the structure, function, growth, History of life, origin, evolution, and distribution of life. Central to biology are five fundamental themes: the cell (biology), cell as the basic unit of life, genes and heredity as the basis of inheritance, evolution as the driver of biological diversity, energy transformation for sustaining life processes, and the maintenance of internal stability (homeostasis). Biology examines life across multiple biological organisation, levels of organization, from molecules and cells to organisms, populations, and ecosystems. Subdisciplines include molecular biology, physiology, ecology, evolutionary biology, developmental biology, and systematics, among others. Each of these fields applies a range of methods to investigate biological phenomena, including scientific method, observation, ...

Handicap Principle
The handicap principle is a hypothesis proposed by the Israeli biologist Amotz Zahavi in 1975. It is meant to explain how "signal selection" during mate choice may lead to Signalling theory, "honest" or reliable signalling between male and female animals which have an obvious motivation to bluff or deceive each other. The handicap principle suggests that secondary sexual characteristics are costly signals which must be reliable, as they cost the signaller resources that individuals with less of a particular trait could not afford. The handicap principle further proposes that animals of greater fitness (biology), biological fitness signal this through handicapping ethology, behaviour, or Morphology (biology), morphology that effectively lowers overall fitness. The central idea is that sexually selected traits function like conspicuous consumption, signalling the ability to afford to squander a resource. Receivers then know that the signal indicates quality, because inferior-quality ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Money
; ), new rich, or new money (in contrast to old money; ) is a social class of the rich whose wealth has been acquired within their own generation, rather than by familial inheritance. These people previously had belonged to a lower social class and economic stratum (rank) within that class and the term implies that the new money, which constitutes their wealth, allowed upward social mobility and provided the means for conspicuous consumption, the buying of goods and services that signal membership in an upper class. As a pejorative term, ''nouveau riche'' affects distinctions of type, the given stratum within a social class; hence, among the rich people of a social class, ''nouveau riche'' describes the vulgarity and ostentation of the newly rich person who lacks the worldly experience and the system of values of ''old money'', of inherited wealth, such as the patriciate, the nobility, and the gentry. History The idea of ''nouveau riche'' dates at least as far back as ancient ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cognition
Cognition is the "mental action or process of acquiring knowledge and understanding through thought, experience, and the senses". It encompasses all aspects of intellectual functions and processes such as: perception, attention, thought, imagination, intelligence, the formation of knowledge, memory and working memory, judgment and evaluation, reasoning and computation, problem-solving and decision-making, comprehension and production of language. Cognitive processes use existing knowledge to discover new knowledge. Cognitive processes are analyzed from very different perspectives within different contexts, notably in the fields of linguistics, musicology, anesthesia, neuroscience, psychiatry, psychology, education, philosophy, anthropology, biology, systemics, logic, and computer science. These and other approaches to the analysis of cognition (such as embodied cognition) are synthesized in the developing field of cognitive science, a progressively autonomou ...
