Self-fulfilling Prophecy
A self-fulfilling prophecy is a prediction that comes true at least in part as a result of a person's belief or expectation that the prediction would come true. In the phenomena, people tend to act the way they have been expected to in order to make the expectations come true. Self-fulfilling prophecies are an example of the more general phenomenon of positive feedback loops. A self-fulfilling prophecy can have either negative or positive outcomes. Merely applying a label to someone or something can affect the perception of the person/thing and create a self-fulfilling prophecy. Interpersonal communication plays a significant role in establishing these phenomena as well as impacting the labeling process. American sociologists W. I. Thomas and Dorothy Swaine Thomas were the first Western scholars to investigate this phenomenon. In 1928, they developed the Thomas theorem (also known as the Thomas dictum): "If men define situations as real, they are real in their consequences." Ano ...

Prediction
A prediction (Latin ''præ-'', "before," and ''dictum'', "something said") or forecast is a statement about a future event or about future data. Predictions are often, but not always, based upon experience or knowledge of forecasters. There is no universal agreement about the exact difference between "prediction" and " estimation"; different authors and disciplines ascribe different connotations. Future events are necessarily uncertain, so guaranteed accurate information about the future is impossible. Prediction can be useful to assist in making plans about possible developments. Opinion In a non-statistical sense, the term "prediction" is often used to refer to an informed guess or opinion. A prediction of this kind might be informed by a predicting person's abductive reasoning, inductive reasoning, deductive reasoning, and experience; and may be useful—if the predicting person is a knowledgeable person in the field. The Delphi method is a technique for elicitin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Poverty Of Historicism
''The Poverty of Historicism'' is a 1944 book by the philosopher Karl Popper (revised in 1957), in which the author argues that the idea of historicism is dangerous and bankrupt. Publication ''The Poverty of Historicism'' was first written as a paper which was read in 1936, then updated, published in a series of articles in '' Economica'' in 1944, and published as a book in English in 1957. It was dedicated “In memory of the countless men and women of all creeds or nations or races who fell victim to the fascist and communist belief in Inexorable Laws of Historical Destiny.” The title is a reference to Marx's book " The Poverty of Philosophy", itself a reference to Proudhon's book "The Philosophy of Poverty". Synopsis The book is a treatise on scientific method in the social sciences. Popper defines historicism as “an approach to the social sciences which assumes that historical prediction is their principal aim…”. He also remarks that “ e belief … that it is ...

Observer-expectancy Effect
The observer-expectancy effect is a form of reactivity in which a researcher's cognitive bias causes them to subconsciously influence the participants of an experiment. Confirmation bias can lead to the experimenter interpreting results incorrectly because of the tendency to look for information that conforms to their hypothesis, and overlook information that argues against it. It is a significant threat to a study's internal validity, and is therefore typically controlled using a double-blind experimental design. It may include conscious or unconscious influences on subject behavior including creation of demand characteristics that influence subjects, and altered or selective recording of experimental results themselves. Overview The experimenter may introduce cognitive bias into a study in several in the observer-expectancy effect, the experimenter may subtly communicate their expectations for the outcome of the study to the participants, causing them to alter their be ...

Clever Hans
Clever Hans (; ) was a horse that appeared to perform arithmetic and other intellectual tasks during exhibitions in Germany in the early 20th century. In 1907, psychologist Oskar Pfungst demonstrated that the horse was not actually performing these mental tasks, but was watching the reactions of his trainer. The horse was responding directly to involuntary cues in the body language of the human trainer, who was entirely unaware that he was providing such cues. In honour of Pfungst's study, this type of artifact in research methodology has since been referred to as the ''Clever Hans effect'' and has continued to be important to the observer-expectancy effect and later studies in animal cognition. Pfungst was an assistant to German philosopher and psychologist Carl Stumpf, who incorporated the experience with Hans into his further work on animal psychology and his ideas on Phenomenology (philosophy), phenomenology.

Psychology
Psychology is the scientific study of mind and behavior. Its subject matter includes the behavior of humans and nonhumans, both consciousness, conscious and Unconscious mind, unconscious phenomena, and mental processes such as thoughts, feelings, and motivation, motives. Psychology is an academic discipline of immense scope, crossing the boundaries between the Natural science, natural and social sciences. Biological psychologists seek an understanding of the Emergence, emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.Hockenbury & Hockenbury. Psychology. Worth Publishers, 2010. A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as Behavioural sciences, behavioral or Cognitive science, cognitive scientists. Some psychologists attempt to understand the role of mental functions in i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Integrated Circuit
An integrated circuit (IC), also known as a microchip or simply chip, is a set of electronic circuits, consisting of various electronic components (such as transistors, resistors, and capacitors) and their interconnections. These components are etched onto a small, flat piece ("chip") of semiconductor material, usually silicon. Integrated circuits are used in a wide range of electronic devices, including computers, smartphones, and televisions, to perform various functions such as processing and storing information. They have greatly impacted the field of electronics by enabling device miniaturization and enhanced functionality. Integrated circuits are orders of magnitude smaller, faster, and less expensive than those constructed of discrete components, allowing a large transistor count. The IC's mass production capability, reliability, and building-block approach to integrated circuit design have ensured the rapid adoption of standardized ICs in place of designs using discre ...

Transistor Count
The transistor count is the number of transistors in an electronic device (typically on a single substrate or silicon die). It is the most common measure of integrated circuit complexity (although the majority of transistors in modern microprocessors are contained in cache memories, which consist mostly of the same memory cell circuits replicated many times). The rate at which MOS transistor counts have increased generally follows Moore's law, which observes that transistor count doubles approximately every two years. However, being directly proportional to the area of a die, transistor count does not represent how advanced the corresponding manufacturing technology is. A better indication of this is transistor density which is the ratio of a semiconductor's transistor count to its die area. Records , the highest transistor count in flash memory is Micron's 2terabyte ( 3D-stacked) 16-die, 232-layer V-NAND flash memory chip, with 5.3trillion floating-gate MOSFETs ( 3bits p ...

Moore's Law
Moore's law is the observation that the Transistor count, number of transistors in an integrated circuit (IC) doubles about every two years. Moore's law is an observation and Forecasting, projection of a historical trend. Rather than a law of physics, it is an empirical relationship. It is an experience-curve law, a type of law quantifying efficiency gains from experience in production. The observation is named after Gordon Moore, the co-founder of Fairchild Semiconductor and Intel and former CEO of the latter, who in 1965 noted that the number of components per integrated circuit had been exponential growth, doubling every year, and projected this rate of growth would continue for at least another decade. In 1975, looking forward to the next decade, he revised the forecast to doubling every two years, a compound annual growth rate (CAGR) of 41%. Moore's empirical evidence did not directly imply that the historical trend would continue, nevertheless, his prediction has held si ...

Theodore Brameld
Theodore Brameld (20 January 1904 – 18 October 1987) was an American philosopher and educator who supported the educational philosophy of social reconstructionism. His philosophy originated in 1928 when he enrolled as a doctoral student at the University of Chicago in the field of philosophy where he trained under the progressive philosopher and politician, T.V. Smith. After becoming intrigued by John Dewey’s philosophy of education, Brameld developed his own theory of schools being the ultimate source to bring about political and social change. Life Early life Theodore Burghard Hurt Brameld was born in Neillsville, Wisconsin in 1904. After graduating from Neillsville High School in 1922, he went on to Ripon College where he received his AB degree in English in 1926. Brameld graduated in 1931 when he completed his dissertation, ''A Philosophic Approach to Communism'', which was eventually published in 1933 and set the standard for the rest of his life's work. ...

Attitude (psychology)
In psychology, an attitude "is a summary evaluation of an object of thought. An attitude object can be anything a person discriminates or holds in mind". Attitudes include beliefs (cognition), emotional responses ( affect) and behavioral tendencies ( intentions, motivations). In the classical definition an attitude is persistent, while in more contemporary conceptualizations, attitudes may vary depending upon situations, context, or moods. While different researchers have defined attitudes in various ways, and may use different terms for the same concepts or the same term for different concepts, two essential attitude functions emerge from empirical research. For individuals, attitudes are cognitive schema that provide a structure to organize complex or ambiguous information, guiding particular evaluations or behaviors. More abstractly, attitudes serve higher psychological needs: expressive or symbolic functions (affirming values), maintaining social identity, and regulating e ...

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.
