The child was instructed to repeat a series of numbers (with increasing numbers of digits) forward and a different series of digits in reverse order. Administration of the Memory for Digit Span The precise instructions and items used in this assessment can be found in the Memory for Digit Span section of the NLSY79 Child Supplement, available on the Questionnaires page. In both parts, the length of each sequence of numbers increases as the child responds correctly.
In Digits Backward, the child listens to a sequence of numbers and repeats them in reverse order. In Digits Forward, the child listens to and repeats a sequence of numbers spoken aloud by the interviewer. Digits Forward primarily taps short-term auditory memory while Digits Backward measures the child's ability to manipulate verbal information while in temporary storage. Each tap distinct but interdependent cognitive functions. There are two parts to the Memory for Digit Span assessment: Digits Forward and Digits Backward. The last survey round to include Memory for Digit Span was 2014.
The WISC-R is one of the best normed and most highly respected measures of child intelligence (although it should be noted that the Digit Span component is one of the two parts of the Wechsler scale not used in establishing IQ tables). The Memory for Digit Span assessment, a component of the Wechsler Intelligence Scales for Children-Revised (WISC-R), is a measure of short-term memory for children aged seven and over (Wechsler 1974).
