Tiivistelmä
sounds into prosodically distinct phonemes by dyslexic adults and their
infants, in the Finnish context. The duration of sounds has a significant role
in Finnish quantity distinctions and the quantity aspect is visibly marked i n
the Finnish orthography. Previous research has shown controversial
evidence on the temporal processing abilities of dyslexics.
In the infant perception experiment a head-tum paradigm was used to
test 6-month old infants' perception of speech stimuli in which the
duration of a stop was varied. There were 89 subjects, half of whom were
infants with high genetic risk for dyslexia (GR+) while the other half were
controls (GR-). The results indicated that the GR+ infants require
significantly longer duration than the GR- infants to shift their perception
from the short to the long quantity category. The same experiment adapted
for adults showed that also adult dyslexics may have a deficiency i n
processing temporal information.
The same adults and infant subjects took part in production
experiments. The results showed that the GR+ infants differed from the
adults more than GR- infants in using durational cues for (C)VCV and
(C)VCCV structures. In particular, the secondary cue in these word
structures appeared to be troublesome for the GR+ infants. Also the dyslexic
adults differed from the control adults in the use of the secondary cue i n
CVCV structures. The findings suggest that there may be a basic temporal
processing deficiency in dyslexics which is apparent early in their
development.
