Abstract:
To establish the influence
of therapeutic differences within the first two weeks of
aural training after cochlear implantation two groups of
patients have been compared on received training and on
CVC scores 1, 2 and 4 weeks after the start of the training.
Materials and methods: Two groups of 9 patients received
training according to the Cochlear Learningmodel, each by
a different therapist. Twelve sessions of each group have
been observed and scored on differences on the six dimensions
of the Cochlear Learningmodel. Consonant-vowel-consonant
word recognition has been scored with Bosmans CVC-wordscore
tests. Results: Differences on wordscores were significant
at all three moments. Differences in therapeutic choices
were found for two dimensions: . Discussion: the
found differences in CVC wordscore may be explained by the
differences in therapeutic choices on the emotional dimension
and/ or the metacognitive dimension. The latter would imply
a critical period for learning to hear details in speech
perception, because the metacognitive skills enables the
patient to focus on details in speech even when the therapist
is not present. The small number of patients and the retrospective
subjective way of scoring of the observed trainings asks
for careful interpretation of the results. However the fact
that even with these small numbers significant differences
were found in CVC-scores and the possible implication that
there is a critical period for learning to hear details
in speech through the use of metacognitive skills asks for
further investigation.
