The present study investigated two measures of spatial acoustic perception in children and adolescents with sensorineural hearing loss (SNHL) tested without their hearing aids and compared it to age-matched controls. Auditory localization was quantified by means of a sound source identification task and auditory spatial discrimination acuity by measuring minimum audible angles (MAA). Both low- and high-frequency noise bursts were employed in the tests to separately address spatial auditory processing based on interaural time and intensity differences. In SNHL children, localization (hit accuracy) was significantly reduced compared to normal-hearing children and intraindividual variability (dispersion) considerably increased. Given the respective impairments, the performance based on interaural time differences (low frequencies) was still better than that based on intensity differences (high frequencies). For MAA, age-matched comparisons yielded not only increased MAA values in SNHL children, but also no decrease with increasing age compared to normal-hearing children. Deficits in MAA were most apparent in the frontal azimuth. Thus, children with SNHL do not seem to benefit from frontal positions of the sound sources as do normal-hearing children. The results give an indication that the processing of spatial cues in SNHL children is restricted, which could also imply problems regarding speech understanding in challenging hearing situations.

Bacground/Aim. Almost 200 cochlear implantations were done in the four centers (two in Belgrade, per one in Novi Sad and Nis) in Serbia from 2002 to 2009. Less than 10% of implantees were postlingually deaf adults. The vast majority, i.e. 90% were pre- and perilingually profoundly deaf children. The aim of this study was to assess the influence of improved auditory perception due to cochlear implantation on comprehension of abstract words in children as compared with hearing impaired children with conventional hearing aids and normal hearing children. Methods. Thirty children were enrolled in this study: 20 hearing impaired and 10 normal hearing. The vocabulary test was used. Results. The overall results for the whole test (100 words) showed a significant difference in favor of the normal hearing as compared with hearing impaired children. The normal hearing children successfully described or defined 77.93% of a total of 100 words. Success rate for the cochlear implanted children was 26.87% and for the hearing impaired children with conventional hearing aids 20.32%. Conclusion. Testing for abstract words showed a statistically significant difference between the cochlear implanted and the hearing impaired children with hearing aids (Mann- Whitney U-test, p = 0.019) implying considerable advantage of cochlear implants over hearing aids regarding successful speech development in prelingually deaf children.

Previous studies have reported both positive and negative effects of deafness on visual attention. The purpose of this study was to replicate and expand findings of previous studies by examining visual attention abilities in children with deafness and children with normal hearing. Twenty-eight children, ages 8–14 years, were evaluated. There were two groups of children with prelingual deafness and one group with normal hearing. The children with deafness were divided further into two groups: those with cochlear implants and those with conventional hearing aids. Unlike previous studies, the current study found no substantial differences in performance among these three groups of children on a continuous-performance visual attention task or on a letter cancellation task. Children in all three groups performed very well on the visual attention tasks. Furthermore, there was little association between performance on the visual attention tasks and parent or teacher ratings of behavior and attention. Age and nonverbal intelligence were significantly correlated with performance on visual attention tasks. The theoretical implications of these findings are discussed, along with directions for future research.
