Two abilities of children-listener (4-6 aging) was studied: 1) recognition of words with one of the syllable replaced with noise and 2) detection of words with one consonants segment replaced with noise. The procedure of reaction on target stimulus presented among the consequence of contexts words was designed using IBM PC. In the recognition paradigm reaction time (RT) was largest and were made less errors for words with 1-st replaced syllable. RT for „pure“ words and words with last syllable replaced did not differ significantly. During the task of detection of distortion no effect of place of the segment distorted was observed. In both paradigms effect of child's age on RT and number of correct responses was revealed. It is proposed 4-5 years old children use on line „up-down“ strategy for word recognition, and this tasks carry out in parallel with detection of non-speech noise in words. This abilities both are developed with age of children.
