Dilin edinimi, dış dünyadan gelen uyaranların algılanması ve üretiminin yapılması ile gerçekleşmektedir. Dilin kazanımı ile zihinsel yeteneklerin ilişkisi günümüzde tartışılmaktadır. Thurston (1938) çoklu faktörler teorisine göre zekanın temel yapısını oluşturduğunu düşündüğü 7 faktörü 'Temel Yetenekler' olarak nitelendirmiştir. İfade ettiği bu faktörlerden biri de kelime akıcılığıdır. Kelime akıcılığı faktörü sözel faktörlerden biridir. Burada önemli olan çok sayıda kelimeyi süratle üretmektir. İngilizcenin konuşma dili olarak kullanıldığı ülkelerde kelime akıcılığı yeteneğinin ölçülmesi için geliştirilmiş olan testlerde yine bu dile özgü kullanım sıklığı belirlenmiş olan K, A, S ve F, A, S sesleri kullanılarak kelime akıcılığı değerlendirilmektedir. Bu seslerin Türk diline uygunluğu araştırılmamıştır.
Objective: The purpose of this study is to evaluate changes in the acoustic properties of voice in patients with profound sensorineural hearing loss to determine the effectiveness of voice therapy. Material-Method: Our study consisted of 15 individuals from the 20-25 years of age with bilateral symmetrical hearing loss (Group A), and 15 individuals in the 26-65 age group with post lingual cochlear implants (Group B). The control group (Group C) included 15 adults with the normal hearing range from the age group of 20-30. Prospective analysis methods was utilized for this research. In order to quantitatively measure the psychosocial consequences of voice-related disorders the Voice Handicap Index (VHI) was given, and, to determine the acoustic measures of the voice quality, the /ah/ sound was digitally recorded with the Multidimensional Voice Program (Kay Elemetrics) in all groups. Conclusion: Average Fundamental frequency (F0), jitter percentage (jitter), shimmer, noise-harmonic ratio (NHR), voice turbulence index (VTI), soft phonation index (SPI), PPQ and APQ parameters were analyzed through acoustic sound analysis program. When the data in Group A are compared with Group B, the acoustic parameters show a statistically significant higher value. Discussion: Speech intelligibility increased in individuals with profound hearing loss who received sound therapy and who used cochlear implants. According to the results of the VHI, individuals with cochlear implants benefit from voice therapy.
Sentral işitsel işlemleme bozukluğunun nöral mekanizmaları, prognozu ve rehabilitasyonu: bir derlemeSantral işitsel işlemleme bozukluğunda bireyler normal işitme eşiklerine sahiptir ancak üst bilişsel süreçler gerektiren dilsel ve işitsel analiz, dikotik dinleme ve ses lokalizasyonu becerilerinde bozulma gözlenir. Hastalığın altında yatan nörobiyolojik mekanizmanın santral işitsel yollarda problem ile ilişki olduğu düşünülmektedir. Bu çalışma, altta yatan nöral mekanizma üzerine literatürdeki çalışmalar ile santral İşitsel İşlemleme bozukluğunun prognozunu ve rehabilitasyonunu değerlendirilmiştir.Anahtar Kelimeler: santral ı̇şitme yolu bozuklukları, ı̇şitme yolları, ı̇şitsel ı̇şleme, odyolojik rehabilitasyon ÖZ Central Auditory Processing Disorder is a disorder in which individuals have normal hearing thresholds, but have difficulty in linguistic and auditory analysis that requires metacognitive processes, impaired dichotic listening and sound localization skills are observed. The neurobiological mechanism underlying the disease is thought to be immaturity or deficit in the central auditory pathways. In this study, studies in the literature on the underlying neural mechanism, prognosis and rehabilitation of Central Auditory Processing Disorder were evaluated.
Background and Aim: Word Recognition Test (WRT) is a widely used component of routine audiology battery. Several studies were conducted on the effect of words in word recognition lists and whether word difficulty level had an effect in word recalling process of patients. This study aims to compare the scores of patients to the designed Başkent WRT and commonly used Hacettepe WRT by focusing on the lexical neighbourhood. Methods: Study carried out in an Ear Nose and Throat Department of a private university hospital between June and August 2021. 34 persons with sensorineural hearing loss and 34 persons without hearing loss was participated in the study. Designed WRT and widely used common WRT were presented to the participants. Results: Results showed that common WRT included words with more lexical neighbours and sensorineural hearing loss group scores were significantly lower compared to designed WRT. Conclusion: Persons with sensorineural hearing loss have a tendency to misunderstand presented words in WRT as they may trigger other words and misguide the patient.
