 note = {application/pdf, This study investigated some features of articulation of 9 Down's syndrome children (DC) in terms of cognitive aspects, comparing them to those of 5 retarded non-Down's syndrome children (non-Down) and 9 normal infants (Normal). The relation between the errors and the length of words, and the position in words which is difficult to be articulated were analyzed. The results indicated that most DC made more errors in the initial syllables in words, and fewer errors in the middle and the final syllables, whereas non-Down and Normal made more errors in the middle syllables, and fewer errors in the initial and the final syllables. The findings suggested that the cognitive mechanism of DC differed from that of other children. DC have some complicated problems in their articulatory disorders, and so require consideration from various angles.},
