Abstract
Background: Phonemic awareness is defined as the ability to break down a word into smaller units called phonemes or described as the ability to synthesize words from segments of one's own speech. Impaired phonemic hearing, depending on the degree of severity, hinders or prevents speech reception, disrupts the proper development of a child's pronunciation, may cause disorders in already developed speech, and complicates the acquisition of writing skills or disturbs the skill that has already been acquired.
Objectives: To create an objectified tool for phonemic hearing diagnostics to ensure that verbal material is always presented at the same intensity, from the same distance, and in the same direction. Another aim was to compare children with and without auditory processing disorder (APD) if they have disrupted phonemic hearing.
Material and methods: A study involving 20 individuals was conducted using a sound level meter to determine the level of the auditory stimulus (therapist's voice) provided to patients during the diagnosis. Each participant in the study was tasked with repeating, in the most natural way for them, 2 pairs of words containing opposing sounds.
Results: The analysis revealed significant discrepancies both in the articulation of verbal material by different examiners and in the presentation of the same material by a single examiner using different methods. When the same phonemic opposition was presented in an identical manner by different diagnosticians, amplitude differences of up to 10.8 dB were observed, with a standard deviation (SD) of 2.5 dB. These findings underscored the need to develop an objectified tool for phonemic hearing diagnostics to ensure consistency and reliability in assessment.
Conclusions: In the research group encompassing children with APD, disorders within phonemic hearing occur more frequently and have a deeper nature. Phonemic hearing disorders in children are associated with significant difficulties in learning and daily functioning.
期刊介绍：
Advances in Clinical and Experimental Medicine has been published by the Wroclaw Medical University since 1992. Establishing the medical journal was the idea of Prof. Bogumił Halawa, Chair of the Department of Cardiology, and was fully supported by the Rector of Wroclaw Medical University, Prof. Zbigniew Knapik. Prof. Halawa was also the first editor-in-chief, between 1992-1997. The journal, then entitled "Postępy Medycyny Klinicznej i Doświadczalnej", appeared quarterly.
Prof. Leszek Paradowski was editor-in-chief from 1997-1999. In 1998 he initiated alterations in the profile and cover design of the journal which were accepted by the Editorial Board. The title was changed to Advances in Clinical and Experimental Medicine. Articles in English were welcomed. A number of outstanding representatives of medical science from Poland and abroad were invited to participate in the newly established International Editorial Staff.
Prof. Antonina Harłozińska-Szmyrka was editor-in-chief in years 2000-2005, in years 2006-2007 once again prof. Leszek Paradowski and prof. Maria Podolak-Dawidziak was editor-in-chief in years 2008-2016. Since 2017 the editor-in chief is prof. Maciej Bagłaj.
Since July 2005, original papers have been published only in English. Case reports are no longer accepted. The manuscripts are reviewed by two independent reviewers and a statistical reviewer, and English texts are proofread by a native speaker.
The journal has been indexed in several databases: Scopus, Ulrich’sTM International Periodicals Directory, Index Copernicus and since 2007 in Thomson Reuters databases: Science Citation Index Expanded i Journal Citation Reports/Science Edition.
In 2010 the journal obtained Impact Factor which is now 1.179 pts. Articles published in the journal are worth 15 points among Polish journals according to the Polish Committee for Scientific Research and 169.43 points according to the Index Copernicus.
Since November 7, 2012, Advances in Clinical and Experimental Medicine has been indexed and included in National Library of Medicine’s MEDLINE database. English abstracts printed in the journal are included and searchable using PubMed http://www.ncbi.nlm.nih.gov/pubmed.
