Objective To investigate the mental health and the affecting factors on children cochlear implants and to provide the reference of comprehensive rehabilitation for them.Methods We used the Psychological Ques-tionnaire for 3~6 Years Children to evaluate the mental health status of 1 6 6 children of 3~4 years old with cochlear implants,and compare those with the standard values of children with normal hearing.We studied the affecting fac-tors on their psychological development.Results The pass rates in action,emotion and will,cognitive ability,sociali-ty,living habits and speech ability of children with cochlear implants decreased as their age increased.The scores of action,emotion and will,cognitive ability,sociality,living habits and speech ability of children with cochlear im-plants increased as the use time increased.The affecting factors on the psychological development of children with cochlear implants were the time length of usage and their residences before operation.Conclusion There were differ-ences between the children with cochlear implants and normal hearing in psychological development.We should fo-cus on their development of hearing and speech ability,and the psychological development.

OBJECTIVE: To assess the evaluation on auditory rehabilitation effect for 42 deaf children with GJB2 gene mutation after cochlear implantation to provide a reference for the cochlear implant effect evaluation of such patients. METHOD: To conduct the detection on common genetic deafness gene mutation hotspots of hearing impaired children with cochlear implantation. To conduct auditory rehabilitation effect evaluation on 42 cases of patients with GJB2 genetic deafness after 3 months, 6 months and 12 months of the operation respectively. The single factor repeated measure ANOVA was applied to analyze whether there were significant difference among the results of initial consonant of a Chinese syllable recognition at 3 different stages after the operation, the results of vowel of a Chinese syllable recognition at 3 different stages after the operation, and the results of two-syllable recognition at 3 different stages after the operation. RESULT: 235delC is the high-incidence mutational site in 42 cases of patients with GJB2 genetic deafness, the total detection rate is up to 90.48%. There were significant differences in the initial consonant of a Chinese syllable recognition rate, the vowel of a Chinese syllable recognition rate, the two-syllable recognition rate as well as the vowel of a Chinese syllable recognition rate after 3 months, 6 months and 12 months of the operation (P < 0.01). CONCLUSION Cochlear implantation is a safe and effective measure for auditory reconstruction, it can help patients with GJB2 hereditary severe sensorineural deafness to improve auditory speech recognition.

Objective The aim of this study is to evaluate word recognition abilities in 4-talker babble noise (BN) in children with normal hearing (NH), and to explore the lexical effects, age on speech recognition ability in children.Methods Children of 3~6 years old with normal hearing (N=212)were participated in this study.One hundred and twenty-four children were performed under the quiet conditions,while 88 were performed in 4-talker babble noise.The standard-Chinese version of the lexical neighborhood test was used to assess spoken word recognition performance.The speech level was 70 dB SPL, and signal to noise ratio (SNR) was chosen 4 dB in BN.Results The correct scores of the NH children in quiet for the DE, DH, ME, and MH words were 96.45%±5.17%, 88.87%±7.73%, 91.90%±7.31% and 82.38%±7.95%, while the scores in BN were 85.34%±11.23%, 66.42%±11.08%, 68.81%±15.99% and 48.58%±12.81%, respectively.The word-recognition performance in BN was significantly poorer than that in quiet.The word recognition scores showed that the lexical effects were significant in the BN (P<0.05).Children scored higher with dissyllabic words than with monosyllabic words;easy words scored higher than hard words in both quiet and noisy environments.The word-recognition performance also increased with age in each lexical category in the 3-to 6-year-old NH children.Conclusion Age and lexical characteristics of words had significant influences on the performance of Mandarin-Chinese word recognition in BN.The lexical effects were more noticeable under noise listening conditions than in quiet.The word-recognition performance in noise increased with age in NH children of 3-to 6-years old in noise and had not reached adult-like performance at 6 years of age.

Objective To analyse the mental health of adolescents with cochlear implants and provide the ref‐erence for programming the personalize rehabilitation schedule of audio - speech -psychological .Methods The mental health test(MHT) was used to evaluate the mental health status of 60 adolescent with cochlear implants ,and compared with those of adolescent with normal hearing .Results The incidence of psychological problems was 3 .33% in adolescent with cochlear implants .The hypersusceptilility scores of the group of cochlear implants (5 .63 ± 2 .22) was higher than that of in normal hearing group(4 .05) in ,which was significantly different(P<0 .01) . The body syndrome scores in the cochlear implants group (4 .03 ± 2 .72) was lower than that of in normal hearing group(4 .99) ,which was significantly different(P<0 .01) .The phobic tendency scores in cochlear implants group (1 .95 ± 2 .01)was significantly lower than that of in normal hearing group (3 .06)(P<0 .01) .Conclusion The over‐all mental health of adolescent with cochlear implants is good .Cochlear implants can help them improve hearing and speech function ,and improve quality of life ,but they still need parents ,teachers and the community to pay more at‐tention and care to help them get through adolescence ,and return to mainstream society .

Objective To study normal hearing children's speech perception in Speech Spectrum -Shaped Noise (SSN) and Babble Noise (BN) using the Mandarin lexical neighborhood test .Methods Thirty -four children with normal hearing were included in this study and randomly assigned to the SSN group and the BN group .Each child was given the 12 lists of Mandarin lexical neighborhood test ,word recognition scores were acquired at different SNRs .Results SNR50 of dissyllablic easy word lists ,dissyllablic hard word lists ,monosyllable easy word lists , monosyllable hard word lists in SSN were -3 dB ,-0 .5 dB ,-1 dB and 3 .5 dB ,respectively ;SNR50 of the four categories lists in BN were -3 dB ,2 dB ,0 .5 dB and 10 dB ,respectively .Lexical effects had a significant influence on spoken word recognition in noise .Especially ,word recognition scores of easy words were higher than those of hard words ,dissyllablic words were better than monosyllable words .Conclusion The masking effects of babble noise on spoken speech perception are stronger than speech spectrum -shaped noise for 3-6 year-old normal hearing chil‐dren .Lexical effects also affet children's speech recognition in noise .

Objective To explore the impact of pre-implant hearing aid fitting on the early open-set word recognition in children who received a cochlear implant(CI) when they were infants .Methods A total of 289 chil‐dren who received a cochlear implant between 0 .9 and 3 .0 years of age were included in this study .According to pre-implant hearing aid fitting ,participants were divided into hearing aid group and non-hearing aid group .The open-set word identification abilities of the cochlear implant children were evaluated via Mandarin Lexical Neighborhood test(M -LNT) .Results Comparisons of the scores of M -LNT between two groups displayed no significant differ‐ence at the same identification age or duration of CI use .Conclusion The abilities of the early open-set word rec‐ognition between hearing aid group and non-hearing aid group didn’t make significant differences for the CI chil‐dren w ho received a cochlear implant betw een 0 .9 and 3 .0 years old .

Objective: The purpose of the present study was to investigate the effects of noise competition on word perception in normal hearing (NH) children and children with cochlear implantation (CI). Methods: To estimate the contribution of noise competition on speech perception, word perception in speech-shaped noise(SSN)and 4-talker babble noise(BN) with Mandarin Lexical Neighborhood Test were performed in 80 NH children and 89 children with CI. Corrected perception percentages were acquired in each group. Results: Both signal to noise ratio (SNR) and noise type influenced the word perception. In NH group, corrected percentages of disyllabic word perception in SSN were 24.2%, 55.9%, 77.1%, 85.1% and 88.9% at -8, -4, 0, 4 and 8 dB SNR, corresponding corrected percentages of monosyllabic word were 13.9%, 39.5%, 60.1%, 68.8% and 80.1%, respectively. In BN noise, corrected percentages of disyllabic word were 2.4%, 24.3%, 55.6%, 74.3% and 86.2%, corresponding monosyllabic word were 2.3%, 20.8%, 47.2%, 61.1% and 74.8%, respectively. In CI group, corrected percentages of dissyllabic word in SSN and BN at 10 dB SNR were 65.5% and 58.1%, respectively. Corresponding monosyllabic word were 49.0% and 41.0%. For SNR=5 dB, corrected percentages of disyllabic word in SSN and BN were 50.0% and 38.1%, corresponding corrected percentages of monosyllabic word were 40.8% and 25.1%, respectively. Analysis indicated that the masking effect were significantly higher in BN compared with SSN. Conclusions Noise competition influence word perception performance significantly. In specific, the influence of noise on word perception is bigger in children with CI than in NH children. The masking effect is higher in BN noise when compared with SSN.
