Jensen

Jensen (1997), a leading proponent of Spearman's idea of general intelligence, or g, makes the following statements. "The positive correlation between all cognitive test items is a given, an inexorable fact of nature. The all-positive interitem correlation matrix is not an artifact of test construction or item selection, as some test critics mistakenly believe" (p. 223). This g factor is highly positively correlated with reation time in completing simple cognitive tasks that take most adults less than one second each (Jensen, 1993).
