The smaller coloured bricks were used for the Kohs Block Design Test, a subtest of the Drever and Collins performance tests of intelligence. This series of non-linguistic tests, devised by psychologists James Drever and Mary Collins in 1928, was designed for deaf children and those with full hearing. The larger white bricks were used for the Visualisation of Cubes Test, part of the British Ability Scales, a measure of cognitive function in children aged 2-17, and were devised by the psychologist Colin Elliott in 1983.
