#Digit span test definition serial
In the original version the subjects had to read sentences while remembering the final words of all the sentences for later serial recall. Training in maintenance and cognitive control: The complex working memory span task Another task that has been used in the working memory training literature is the complex working memory span task introduced by Daneman and Carpenter (1980).Each child was required to count aloud the number of green dots on each card these numbers were to be stored and subsequently recalled in the correct order. In de Jong’s design, a card was presented to each child, on which an irregular pattern of green and yellow dots was printed. In the same study, de Jong (1998) used a counting span test based on Case, Kurland, and Goldberg’s (1982) design.The counting span test requires respondents to retain and reproduce a series of digits while counting.
As the number of computations increased from two to seven, so the list of numbers that had to be stored also increased. After the digit was presented, the child was required to immediately begin the next computation, so as to minimize the possibility of rehearsal. Each computation consisted of either the addition or subtraction of 1 from a number less than 10, and the correct answer was always less than 10. Analogous to the reading span tests employed in the same study (de Jong, 1998), each computation span test item required the child to first read and solve aloud a simple mathematical computation (e.g., 3+1) immediately before listening to a single digit spoken by the test administrator. Based on the Operation Word task used by Turner and Engle (1989), de Jong (1998) employed the computation span test to distinguish ditferences in memory processing and storage.
