dc.description.abstract | Verbal memory depends on the quality of speech perception and
development of linguistic structures depends on verbal memory.
These facts point to a closed circuit of cause and effect sufficiently
well-developed speech and language in children with language disorders.
For the smooth progress of speech perception, good condition
and functions of all parts of the auditory system is necessary. Damage
or dysfunction in any part of the auditory system can lead to disorders
of speech perception, which affects the state of verbal memory, from
which follows the occurrence of different disorders in verbal communication.
The aim of this research is to investigate the impact of
quality of speech perception on verbal memory in children with
developmental dysphasia. The study included 20 children with
developmental dysphasia (experimental group),aged from 5 to 7 years
and 30 children with normal speech and language development of the
same age (control group). To evaluate the quality of speech perception
in children in the experimental and control groups was used the
technique of speech audiometry with the use of specially designed
word lists (Plecevic, Djokovic, 1997),and for the evaluation of verbal
memory was used test to examine immediate and delayed verbal
memory (S. Vladisavljeviæ, 1983). By analyzing the results of our
research we found that children with developmental dysphasia
showed significantly worse results, or worse ability to retain verbal
content compared to children with regular speech and language
development. Children with developmental dysphasia need a higher
intensity of the speech signal in order to properly reproduce presented
words compared to children with normal speech and language
development. We determined the influence of quality of speech perception
on verbal memory in children with developmental dysphasia,
enabling the identification of new regularities and correlations of
quality of speech perception and verbal memory. | |
