Rivermead Perceptual Asesment Battery, 1991.
© Science Museum / Science & Society Picture Library
Invented in 1985 by pyschologists S Whiting, N Lincoln, G Bhavani and J Cookburn, the Rivermead test is an asesment test for deficits in visual perception, based on patients between 17 and 69 years old. Following a head injury or stroke, asesing a patient's level of visual perceptual deficit plays an important part in determining an appropriate rehabilitation therapy. This asesment helps to evaluate whether a person has difficulty with visual perceptual tasks by testing their abilities to match objects of different colours, shapes, sizes and sequences, via 16 separate subtests.
