In 1961, at the age of 15, study members were given their third
set of cognitive tests. The tests were selected to look at a broad
range of abilities and included verbal and non-verbal reasoning,
reading and mathematics, and followed on from similar tests given
at ages 8 and 11. These tests were given to study members under the
supervision of a member of their school staff.
The tests selected in 1961 were the Alice Heim (AH4) test, the
Watts-Vernon reading test and a mathematics test specifically
constructed for the NSHD. In the full set administered there were
212 questions grouped into 4 separate timed tests; it was highly
unusual for anyone to finish the complete test; indeed they were
designed to push students. The test themselves were ideally given
to study members in the morning, on two consecutive days. On the
first day study members sat the verbal and non-verbal reasoning
tests. On the second day the reading and mathematics test were
Below are links to shortened versions of the four separate timed
tests. These too are time limited although we have allowed more
time than study members would have had in 1961!
For each test there is a page of short instructions, followed by
the test itself.
Good luck and enjoy!
