Document Summary
Psychometric approach - theory and technique of psychological measurement, concerned with objective measurement of skills and knowledge, abilities, attitudes, personality traits, and educational achievement. Spearman measured how well people performed tasks such as following directions, judging musical pitch, matching colors, and doing arithmetic. He found that performance on any task correlated positively with performance on any of the others and inferred that all the tasks have something in common. He also argued that people need a general ability, which he called g as well as a specific ability. Therefore, intelligence consists of a general ability plus an unknown number of specific abilities, such as mechanical, musical, arithmetical, logical, and spatial abilities. Spearman called his theory a monarchic theory of intelligence because it has a dominant ability (the monarch) and lesser abilities. Researchers have confirmed spearman"s study and results. For any intellectual task, holding information in the memory and shifting attention is important.
