Abstract
A computerized test for oral language perception (TIPLO) has been developed to evaluate the abilities of young children (from age 2) and of children with language disorders (including a lack of language production) to perceive and discriminate phonetic information. The test has a computer game presentation that makes it easy to use with very young children. An experiment with normally developing children aged 18-33 months and with children with severe language disorders showed that all children had no problems with the test. Children had to point out one of the two or four images displayed simultaneously on the screen after hearing oral instructions given through the computer loudspeakers. There were two versions of the test: one tested phonetic discrimination and semantic knowledge, the other semantic knowledge only. Each test consisted of 20 items and lasted about 15 minutes.
