Robert Selman developed his developmental theory of role-taking ability based on four sources. [4] The first is the work of M. H. Feffer (1959, 1971), [5] [6] and Feffer and Gourevitch (1960), [7] which related role-taking ability to Piaget's theory of social decentering, and developed a projective test to assess children's ability to decenter as they mature.

This machine invented the principle of the modern computer and was the birthplace of the stored program concept that almost all modern day computers use. [52] These hypothetical machines were designed to formally determine, mathematically, what can be computed, taking into account limitations on computing ability.
The first digital electronic computer was developed in the period April 1936 - June 1939, in the IBM Patent Department, Endicott, New York by Arthur Halsey Dickinson. [35] [36] [37] In this computer IBM introduced, a calculating device with a keyboard, processor and electronic output (display). The competitor to IBM was the digital electronic ...
The first known computer algorithm was written by Ada Lovelace in the 19th century for the Analytical Engine, to translate Luigi Menabrea's work on Bernoulli numbers for machine instruction. [3] However, this remained theoretical only - the lesser state of engineering in the lifetime of these two mathematicians proved insufficient [ citation ...

[21] In 1912, his family moved to East Prussian Braunsberg (now Braniewo in Poland), where his father was a postal clerk.Zuse attended the Collegium Hosianum in Braunsberg, and in 1923, the family moved to Hoyerswerda, where he passed his Abitur in 1928, qualifying him to enter university.
It was developed by Fred Davis and Richard Bagozzi. [ 1 ] [ 6 ] [ 7 ] TAM replaces many of TRA's attitude measures with the two technology acceptance measures— ease of use , and usefulness . TRA and TAM, both of which have strong behavioural elements, assume that when someone forms an intention to act, that they will be free to act without ...
