title: [Investigations on the incidence of partial agnosia of sounds (author's transl)].
abstract: Stammering as a frequent speech disorder in infancy results from many causes. For instance, it is possible that a child with normal peripheral hearing may be unable to distinguish sounds by tone and therefore will repeat them incorrectly. A testing method is presented in which paired pictures are used which differ by the phonologic opposition of some stammered sounds. The results of the test in 100 children who stammer are reported. Further investigations give evidence that other perceptual disorders can be found in supposed agnosias.
