The purpose of this study was to establish the criteria for dysfluency in young children. The subjects were 50 normal children at the age between two and six years who lived in Taegu at the time of the investigation. Each subject was asked to talk a story about the pictures. Video tapes were made to analyze his/her speech sample in terms of the patterns and the frequency of dysfluency, the repeated units in the part-word repetition, and any changes of occurence with time.
The results of this study were as follows:
1. Injection was the most frequently occuring pattern of normal dysfluency, followed by pause and whole-word repetition. Part-word repetition was decreased after 3 years old while revision was increased gradually.
2. The frequency of dysfluency was decreased with age. The frequency of dysfluency per 100 words was 11.46 at the age of two, 9.83 at the age of three, 7. 8 at the age of four, 7.14 at the age of five, and 5.93 at the age of six.
3. There was no difference in the frequency of dysfluency with time.
