About the Raven's Mill Hill Vocabulary Scale
During World War II, John Raven was working at the Mill Hill Emergency Hospital in London (a wartime relocation of the Maudsley Hospital). The hospital handled both psychiatric cases and brain-injured servicemen, and Raven needed a cognitive battery that could distinguish between general intellectual deterioration and specific brain-injury patterns.
The Raven Matrices alone measured what Raven called 'eductive ability' (now called fluid intelligence): the capacity to reason about novel problems without verbal content. To round out the assessment, Raven needed a measure of 'reproductive ability' (now called crystallized intelligence): accumulated verbal knowledge that should be relatively preserved in cases of brain injury that affected only fluid abilities. The Mill Hill Vocabulary Scale was the answer.
The Mill Hill consisted of 88 multiple-choice vocabulary items of increasing difficulty. The combination of Matrices + Mill Hill gave a complete cognitive picture: fluid IQ + crystallized IQ + the difference between them (which could indicate brain injury when fluid was much lower than crystallized). The Matrices + Mill Hill combination remained the most-used UK cognitive battery for nearly 60 years.
