Daniel McCartney
Daniel McCartney (September 10, 1817 – November 15, 1887) was an American who had (what is now known as) Highly Superior Autobiographical Memory (HSAM). McCartney was born in Westmoreland County, Pennsylvania. He was legally blind and lived with relatives throughout his lifetime. For a large part of his life, he resided in Morrow County, Ohio, before his final days in Muscatine, Iowa. He never married. McCartney was famous for his mental ability in two specific areas, memory and calculation. He remembered every single day in his life from the age of nine until his death. Given any specific calendar date, McCartney could, in seconds, give the day of the week, describe the weather conditions, describe what he did during the day, describe what he ate during the day, and provide details of local, regional and national events on that day. In a similar case to McCartney's, noted neurobiologist James McGaugh of the University of California, Irvine, one of the world's leading experts o ...

Hyperthymesia
Hyperthymesia, also known as hyperthymestic syndrome or highly superior autobiographical memory (HSAM), is a condition that leads people to be able to remember an abnormally large number of their life experiences in vivid detail. It is extraordinarily rare, with only 61 people in the world having been diagnosed with the condition as of 2021. American neurobiologists Elizabeth Parker, Larry Cahill, and James McGaugh (2006) identified two defining characteristics of hyperthymesia: spending an excessive amount of time thinking about one's past, and displaying an extraordinary ability to recall specific events from one's past. The authors wrote that they derived the word from Ancient Greek: ''hyper-'' ("excessive") and ''thymesis'' ("remembering"), but there is no such word as ''thymesis''; it may allude to the Greek ''enthymesis'', which means "consideration", and is derived from ''thymos'' "mind". Signs and symptoms Individuals with hyperthymesia can extensively recall the event ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salem, Ohio
Salem is the largest city in Columbiana County, Ohio, with a small district in southern Mahoning County. At the 2020 census, the city's population was 11,915. It is the principal city of the Salem micropolitan area in Northeast Ohio. It is 18 miles (28 km) southwest of Youngstown, 28 miles (45 km) east of Canton, and 60 miles (97 km) southeast of Cleveland. Founded by the Quaker society in 1806, Salem was notably active in the abolitionist movement of the early- to mid-19th century as a hub for the American Underground Railroad. Through the 20th century, Salem served as one of many industrial towns in Northeast Ohio's Mahoning Valley region. Today, the city is a commuter town and an economic center of Columbiana County, home to Allegheny Wesleyan College and Kent State University at Salem. History Salem was founded by a New Jersey clockmaker, Zadok Street, and a Pennsylvanian potter, John Straughan, in 1806. The city was named after Salem, New Jersey, Street†...

American Journal Of Psychology
The ''American Journal of Psychology'' is a journal devoted primarily to experimental psychology. It is the first such journal to be published in the English language (though ''Mind'', founded in 1876, published some experimental psychology earlier). ''AJP'' was founded by the Johns Hopkins University psychologist Granville Stanley Hall in 1887. This quarterly journal has distributed several groundbreaking papers in psychology . The AJP investigates the science of behavior and the mind, releasing reports of original research based on experimental psychology, theoretical presentations, combined theoretical and experimental analyses, historical commentaries, and detailed reviews of well-known books. Abstracting and indexing The journal is abstracted and indexed in Academic ASAP, JSTOR, BIOSIS, and Scopus Scopus is Elsevier's abstract and citation database launched in 2004.

Mental Calculators
Human calculator is a term to describe a person with a prodigious ability in some area of mental calculation (such as adding, subtracting, multiplying or dividing large numbers). The world's best mental calculators are invited every two years to compete for the Mental Calculation World Cup. On July 17, 2022, at Heinz Nixdorf MuseumsForum in Paderborn city of Germany, 12-year-old Indian mental calculator Aaryan Nitin Shukla clinched the title to become the new World Champion. Aaryan ended the dominance of Japanese mental calculators who won the competitions during 2018-Tomohiro Iseda and 2016-Yuki Kimura. Tomohiro Iseda (2018) was the third Japanese person to win the Cup, after Naofumi Ogasawara (2012) and Yuki Kimura (2016). Shakuntala Devi from India has been often mentioned on the Guinness World Records. Neelakantha Bhanu Prakash from India has been often mentioned on the Limca Book of Records for racing past the speed of a calculator in addition. Srilankan-Malaysian perfo ...

Wilton, Iowa
Wilton (formerly Wilton Junction) is a city in Cedar and Muscatine counties in the U.S. state of Iowa. The population was 2,924 at the time of the 2020 census. The Muscatine County portion of Wilton is part of the Muscatine Micropolitan Statistical Area. History The first settler to build a home in the area that was to be known as Wilton in the new state of Iowa (1846) was Mr. Christian Marolf who came in July 1849, and erected of a small log house opposite the German Lutheran church. When he built his home Mr. Marolf could only see one the home of Mr. Stearns just west of town on the south side of the Moscow road.

Cube Root
In mathematics, a cube root of a number is a number such that . All nonzero real numbers, have exactly one real cube root and a pair of complex conjugate cube roots, and all nonzero complex numbers have three distinct complex cube roots. For example, the real cube root of , denoted \sqrt[3]8, is , because , while the other cube roots of are -1+i\sqrt 3 and -1-i\sqrt 3. The three cube roots of are :3i, \quad \frac-\fraci, \quad \text \quad -\frac-\fraci. In some contexts, particularly when the number whose cube root is to be taken is a real number, one of the cube roots (in this particular case the real one) is referred to as the ''principal cube root'', denoted with the radical sign \sqrt[3]. The cube root is the inverse function of the cube (algebra), cube function if considering only real numbers, but not if considering also complex numbers: although one has always \left(\sqrt[3]x\right)^3 =x, the cube of a nonzero number has more than one complex cube root and its ...

Human Memory
Memory is the faculty of the mind by which data or information is encoded, stored, and retrieved when needed. It is the retention of information over time for the purpose of influencing future action. If past events could not be remembered, it would be impossible for language, relationships, or personal identity to develop. Memory loss is usually described as forgetfulness or amnesia. Memory is often understood as an informational processing system with explicit and implicit functioning that is made up of a sensory processor, short-term (or working) memory, and long-term memory. This can be related to the neuron. The sensory processor allows information from the outside world to be sensed in the form of chemical and physical stimuli and attended to various levels of focus and intent. Working memory serves as an encoding and retrieval processor. Information in the form of stimuli is encoded in accordance with explicit or implicit functions by the working memory processor. Th ...
