TAILIEUCHUNG - Cochlear Implants: Fundamentals and Application - part 9

Khi phân biệt đối xử diễn ra sự kích thích điện cực là một nhiệm vụ nhận thức khác nhau từ sân xếp hạng, điều này cũng tương quan với thời gian điếc. Khả năng của trẻ em để xếp hạng sân tonotopically (tức là, theo vị trí của kích thích), chứ không phải là điện cực đặt chỉ đơn giản là phân biệt đối xử | 658 11. Rehabilitation and Habilitation As discriminating place of electrode stimulation is a different perceptual task from ranking pitch this was also correlated with duration of deafness. The ability of children to rank pitch tonotopically . according to place of stimulation rather than simply discriminate electrode place was compared with their speech perception scores as shown in Figure . The poorest results were found in those not able to order pitch Absent . In addition those children with the longest duration of deafness had the lowest scores on the Bamford-Kowal-Bench BKB Bench and Bamford 1979 word-in-sentence test. Furthermore it can be seen Fig. that not all children who could rank pitch Present had good speech perception results. For 75 of the 16 children in the study a tonotopic ordering of pitch percepts was found Present . However only 58 of these children with good ability to rank pitch had satisfactory speech perception of 30 or more. This suggested that the effect of developmental plasticity on the neural connectivity required for place discrimination was not the only factor for learning speech. At least another factor was required for speech perception most probably language as discussed below and in Chapter 7. In another group of children from the University of Melbourne s Cochlear Implant Clinic that were unselected the data showed speech perception was significantly better the younger the child when the implant surgery was performed Fig. . The scores were obtained 2 years or longer after implantation. Cochlear Implants Postdevelopmental Plasticity An important question for cochlear implantation is Would a patient who had adjusted to a certain speech-processing strategy get further benefits from an al- Figure . Place pitch ranking versus word scores for the Bamford-Kowal-Bench BKB open-set sentences for electrical stimulation alone on 16 children using cochlear implant. Pitch ranking is classified as present or absent. .
