Abstract
T
here is a link between prolonged mobile phone use and serious health problems. World Health Organization’s scientific panel classified mobile phone radiation as ‘possibly carcinogenic’. Also excessive use of mobile phones is known to cause headache, deleterious effects on concentration and attention, memory loss and depression.
Video game playing has become one of the main leisure activities for children and adolescents. Mobile phones represent one of the tools for video games. The effect of video games playing was variable in literature. As central auditory pathway is responsible for the processing the auditory information, examining central auditory processing abilities is considered as an integral part of the detection of difficulties listening in background noise, following oral instructions, and understanding rapid or degraded speech in the presence of normal peripheral hearing, etc.
To the best of author knowledge, there is no study investigated effects of mobile devices usage and video games playing on central auditory processing in school-aged children.
The aim of the work is to examine the central auditory processing abilities in school-aged children who use mobile phones and play video games.
The present study consisted of 50 normal hearing children with age ranging between 6 and 12 years. All participants in this study were submitted to full history taking from parents, Parents - administered sheet for history of mobile phone use, Parents - administered Questionnaire for screening of CAPD, Psychometric evaluation: using Stanford-Binet Intelligence Scale fifth edition (SB5) with average score conducted by psychologist at phoniatric unit of Ain-Shams University Hospitals. Otological examination, basic audiological evaluation including: Pure- tone audiometry, speech audiometry, immitancemetry. Also central auditory processing tests were done including: Speech Intelligibility In Noise (SPIN), Arabic Dichotic Digit test (DD) (version I& II), Auditory Fusion Test- Revised (AFT-R), Memory tests (Recognition Memory, Memory for Content, Memory for Sequence), Auditory Continuous Performance Test (ACPT) and Auditory Vigilance test.
Concerning the mobile phone history most of children in the study group played video games using mobile phones and computer or laptop. Racing & violent games were the most favorite type of games. Thirty-six percent of children had moderate to poor scholastic achievement, the number of hours that children use mobile phones ranged between (1- 8) hours / day with an average of 3.5 hours / day.
Parents questionnaire concerning the central auditory processing abilities revealed that 82% of parents have concern about the memory of the children, lack of attention and concentration in 76% and impulsivity in 32%.
The results of the present study demonstrated that most of video game playing children had abnormal scores in most of central auditory processing abilities, with the highest percentage of abnormality was in selective attention ability followed by sequential memory.
Additionally, there was a significant Association between the results of central auditory processing tests and the concern of parents from CAP questionnaire about memory, concentration, attention and scholastic achievement.
Also, it was found that there was Association between central auditory processing abilities as memory and attention and duration of mobile phone use.
Finally, from the present work it could be concluded that the children who excessively use mobile phone and video games usually have poor scholastic achievement and they should be assessed for the central auditory processing abilities. The central auditory processing deficit is unseen disability, so decreasing the time of usage of mobile phones and all technology including video games and central remediation program would improve the central processing ability which in turn has an impact on the scholastic performance of those children.
