Explore where selected cohorts overlapped in their assessment of cognitive abilities at the ages of 46 to 53.
For background guidance on the table below, see the main harmonisation feasibility page in this guide.
Ability domain | NSHD (Age 53) | NCDS (Age 50) | BCS70 (Age 46) |

Glr (Long-term storage & retrieval) - Verbal memory | Immediate and Delayed Verbal Learning/ Word List Recall Test | Immediate and Delayed Verbal Learning/ Word List Recall Test | Immediate and Delayed Verbal Learning/ Word List Recall Test |
