Elementary Cognitive Task
An elementary cognitive task (ECT) is any of a range of basic tasks which require only a small number of mental processes and which have easily specified correct outcomes.Human Cognitive Abilities: A Survey of Factor-Analytic Studies By John Bissell Carroll 1993 Cambridge University Press p11 The term was proposed by John Bissell Carroll in 1980, who posited that all test performance could be analyzed and broken down to building blocks called ECTs. Test batteries such as Microtox were developed based on this theory and have shown utility in the evaluation of test subjects under the influence of carbon monoxide or alcohol.

John Bissell Carroll
John Bissell Carroll (June 5, 1916 – July 1, 2003) was an American psychologist known for his contributions to psychology, linguistics and psychometrics.Stansfield, Charles W. “Carroll, John Bissell.” ''Concise Encyclopedia of Educational Linguistics''. Ed. B. Spolsky. Amsterdam; New York: Elsevier, 1999. Early life and education Carroll was born in Hartford, Connecticut. Early in his life, Carroll became interested in music and language. His interest in language was furthered by his friendship with Benjamin Lee Whorf at the age of thirteen and discussing Whorf's ideas about a close connection between culture and language. Carroll also helped to edit and publish Whorf's ''Language, Thought and Reality'' in 1956. Carroll studied at Wesleyan University, majoring in classics and graduating ''summa cum laude'' in 1937. He attended the University of Minnesota to earn a doctoral degree in psychology afterwards. At the University of Minnesota, Carroll began studying under B ...

Carbon Monoxide
Carbon monoxide (chemical formula CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest oxocarbon, carbon oxide. In coordination complexes, the carbon monoxide ligand is called ''metal carbonyl, carbonyl''. It is a key ingredient in many processes in industrial chemistry. The most common source of carbon monoxide is the partial combustion of carbon-containing compounds. Numerous environmental and biological sources generate carbon monoxide. In industry, carbon monoxide is important in the production of many compounds, including drugs, fragrances, and fuels. Indoors CO is one of the most acutely toxic contaminants affecting indoor air quality. CO may be emitted from tobacco smoke and generated from malfunctioning fuel-burning stoves (wood, kerosene, natural gas, propane) and fuel-burning heating systems (wood, oil, n ...

Alcohol (drug)
Alcohol, sometimes referred to by the chemical name ethanol, is the active ingredient in alcoholic drinks such as beer, wine, and distilled spirits (hard liquor). Alcohol is a central nervous system (CNS) depressant, decreasing Action potential, electrical activity of neurons in the brain, which causes the characteristic effects of alcohol intoxication ("drunkenness"). Among other effects, alcohol produces euphoria, anxiolytic, decreased anxiety, increased sociability, sedation, and impairment of cognitive, memory, motor control, motor, and sense, sensory function. Alcohol has a variety of adverse effects. Short-term effects of alcohol consumption, Short-term adverse effects include generalized impairment of neurocognitive function, dizziness, nausea, vomiting, and symptoms of hangover. Alcohol is addiction, addictive and can result in alcohol use disorder, Substance dependence, dependence, and Alcohol withdrawal syndrome, withdrawal upon cessation. The long-term effects of ...

National Academies Press
The US National Academies Press (NAP) was created to publish the reports issued by the National Academies of Sciences, Engineering, and Medicine (formerly known as the National Research Council (United States), National Research Council), the National Academy of Engineering, National Academy of Sciences, National Academy of Engineering, and the National Academy of Medicine. It publishes nearly 500 titles a year on a wide range of topics in the sciences, engineering, medicine, and transportation . The NAP's stated mission is seemingly self-contradictory: to disseminate as widely as possible the works of the National Academies of Sciences, Engineering, and Medicine, and to be financially self-sustaining through sales. This mission has led to great experimentation in openness regarding online publishing and open access. The National Academy Press, as it was known in 1993, was the first self-sustaining publisher to make its material available on the Web, for free, in an open access m ...

Mental Chronometry
Mental chronometry is the scientific study of processing speed or reaction time on cognitive tasks to infer the content, duration, and temporal sequencing of mental operations. Reaction time (RT; also referred to as "response time") is measured by the elapsed time between stimulus onset and an individual's response on elementary cognitive tasks (ECTs), which are relatively simple perceptual-motor tasks typically administered in a laboratory setting. Mental chronometry is one of the core methodological paradigms of human experimental, cognitive, and differential psychology, but is also commonly analyzed in psychophysiology, cognitive neuroscience, and behavioral neuroscience to help elucidate the biological mechanisms underlying perception, attention, and decision-making in humans and other species. Mental chronometry uses measurements of elapsed time between sensory stimulus onsets and subsequent behavioral responses to study the time course of information processing in th ...

Inspection Time
Inspection time refers to the exposure duration required for a human subject to reliably identify a simple stimulus. Typically a stimulus made up of two parallel lines differing in length and joined at the tops by a cross bar is presented (similar to the Greek letter Pi). The ability to quickly detect the identity of a stimulus is moderately heritable and correlates with the subject's IQ. Overview If asked which of the two lines in the figure below is longer; the left or the right, almost all non-visually impaired subjects can answer correctly 100% of the time. If, however, the stimulus is backward masked after a short period of time, the proportion of correct responses declines as the exposure duration reduces, and reliable individual differences emerge in the percent identified correctly at different intervals. The task itself was proposed by Doug Vickers as a measure of the rate of accumulation of information. Ted Nettelbeck, Chris Brand and others demonstrated it related ...

Psychological Tests And Scales
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] |
