Short-term memory (or "primary" or "active memory") is the capacity for holding a small amount of information in mind in an active, readily available state for a short period of time. The duration of short-term memory (when rehearsal or active maintenance is prevented) is believed to be in the order of seconds. A commonly cited capacity is 7 ± 2 elements. In contrast, long-term memory indefinitely stores a seemingly unlimited amount of information.

Short-term memory should be distinguished from working memory, which refers to structures and processes used for temporarily storing and manipulating information (see details below)

The idea of a division of memory into short-term and long-term dates back to the 19th century. A classical model of memory developed in the 1960s assumed that all memories pass from a short-term to a long-term store after a small period of time. This model is referred to as the "modal model" and has been most famously detailed by Shiffrin. The exact mechanisms by which this transfer takes place, whether all or only some memories are retained permanently, and indeed the existence of a genuine distinction between the two stores, remain controversial topics among experts.

Clive Wearing (May 11, 1938) is a British musicologist, conductor, tenor and keyboardist suffering from an acute and long-lasting case of anterograde and retrograde amnesia, meaning that he lacks both the ability to form new memories and to recall some aspects of his past memories.

Clive Wearing is an accomplished musician, and is known for editing the works of Orlande de Lassus. Wearing sang at Westminster Cathedral as a tenor lay clerk for many years and also had a successful career as a chorus master and worked as such at Covent Garden and the London Sinfonietta Chorus.

In 1968 he founded the Europa Singers of London, an amateur choir specialising in music of the 17th, 18th and 20th centuries. It won critical approval especially for performances of the Monteverdi Vespers. In 1977 it gave the first performance in the Russian Cathedral of Sir John Tavener's setting of the Liturgy of St. John Chrysostom with Roderick Earle as bass soloist, and subsequently made a recording (Ikon Records No. 9007). The Europa Singers also competed in the XXXII Concorso Polifonico Internazionale in Arezzo in 1984, and provided choruses for operas staged by the London Opera Centre, including Lully's Alceste and Mozart's Marriage of Figaro, which was performed at Sadler's Wells.

"The Man" is a slang phrase that may refer to the government or to some other authority in a position of power. In addition to this derogatory connotation, it may also serve as a term of respect and praise.

The phrase "the Man is keeping me down" is commonly used to describe oppression. The phrase "stick it to the Man" encourages resistance to authority, and essentially means "fight back" or "resist", either openly or via sabotage.

The earliest recorded use^{[citation needed]} of the term "the Man" in the American sense dates back to a letter written by a young Alexander Hamilton in September 1772, when he was 15. In a letter to his father James Hamilton, published in the Royal Dutch-American Gazette, he described the response of the Dutch governor of St. Croix to a hurricane that raked that island on August 31, 1772. "Our General has issued several very salutary and humane regulations and both in his publick and private measures, has shewn himself the Man." ^{[dubious – discuss]} In the Southern U.S. states, the phrase came to be applied to any man or any group in a position of authority, or to authority in the abstract. From about the 1950s the phrase was also an underworld code word for police, the warden of a prison or other law enforcement or penal authorities.

Daniel Lawrence Schacter (born June 17, 1952 in New York) is an American psychologist. He is a Professor of Psychology at Harvard University. His research has focused on psychological and biological aspects of human memory and amnesia, with a particular emphasis on the distinction between conscious and nonconscious forms of memory and, more recently, on brain mechanisms of memory distortion.

He received his B.A. from the University of North Carolina at Chapel Hill in 1974, M.A. and Ph.D. from the University of Toronto in 1977 and 1981 respectively. His Ph.D. thesis was supervised by Endel Tulving. In 1978, he was a visiting researcher at the University of Oxford's Department of Experimental Psychology. He has also studied the effects of aging on memory. His research uses both cognitive testing and brain imaging techniques such as positron emission tomography and functional magnetic resonance imaging. Schacter has written three books, edited seven volumes, and published over 200 scientific articles and chapters. His books include: Searching for Memory: The Brain, the Mind, and the Past (1996); Forgotten ideas, neglected pioneers: Richard Semon and the story of memory. (2001); The Seven Sins of Memory: How the Mind Forgets and Remembers (2001).
