The nature of the colour retention deficit in Down's syndrome.
In Sinson and Wetherick (1973) the authors reported evidence that Down's syndrome children show a deficit in short-term retention of colour information not shown by matched S.S.N. controls. The experiments were conducted in good daylight illumination. Repetition in blue weak artificial light showed that retention of green, red and purple was much improved but that the other colours were not affected. Implications of the finding are considered for theories of colour vision and short-term retention and for educational technology.
