To determine whether there is a general capacity for all working memory tasks Turner and Engle (1989) developed a task called "operation-word-span" (OSPAN): a task in which subjects are asked to verify a simple mathematical equation (e.g. 4/2 +1 = 3) as true or false, and then read a word (e.g. SNOW). Several verify/read pairs are sequenced in succession, followed by a recall test. The maximum number of words that can be recalled is defined as a person's "operation span".
Complex-span tasks have also been shown to be closely related to many other aspects of complex cognitive performance besides language comprehension, among other things to measures of fluid intelligence.
