This was taken at about age 11 on June 4th in the Scottish Mental Survey of 1947 [51]. It was re-administered when participants were seen again at about age 70, using the same instructions and 45-minute time limit. Only two small changes were made to items whose content had become archaic [10]. The test is often referred to as a 'verbal' or 'verbal reasoning' test. However, the test has items of a variety of types: following directions (14 items), same-opposites (11), word classification (10), analogies (8), practical items (6), reasoning (5), proverbs (4), arithmetic (4), spatial items (4), mixed sentences (3), cypher decoding (2), and other items (4). A score of 76 was the maximum possible in the Moray House Test (MHT). With the collaboration of the SCRE, records from the original SMS1947 ledgers (held at the SCRE Centre's office in the University of Glasgow) containing MHT scores were checked to ensure a complete and accurate electronic index of individuals who sat the MHT. The SMS1947 database was used to obtain the MHT scores for all participants who attended the LBC1936 study and gave permission.
