Click on the individual cognitive measures in the table below to find out more.
Along with raw and normalised variables for each cognitive test in childhood, the NSHD contains three standardised summary variables (COG8H, COG11H, and COG15H). These were calculated by transforming the raw scores of each measure to standardised z-scores, summing these z-scores, then re-standardising this total score . Thus, these derived variables provide a simple global cognitive functioning score.
