Environmental Sound Training in Cochlear Implant Users

Purpose The study investigated the effect of a short computer-based environmental sound training regimen on the perception of environmental sounds and speech in experienced cochlear implant (CI) patients. Method Fourteen CI patients with the average of 5 years of CI experience participated. The protocol consisted of 2 pretests, 1 week apart, followed by 4 environmental sound training sessions conducted on separate days in 1 week, and concluded with 2 posttest sessions, separated by another week without training. Each testing session included an environmental sound test, which consisted of 40 familiar everyday sounds, each represented by 4 different tokens, as well as the Consonant Nucleus Consonant (CNC) word test, and Revised Speech Perception in Noise (SPIN-R) sentence test. Results Environmental sounds scores were lower than for either of the speech tests. Following training, there was a significant average improvement of 15.8 points in environmental sound perception, which persisted 1 week later after training was discontinued. No significant improvements were observed for either speech test. Conclusions The findings demonstrate that environmental sound perception, which remains problematic even for experienced CI patients, can be improved with a home-based computer training regimen. Such computer-based training may thus provide an effective low-cost approach to rehabilitation for CI users, and potentially, other hearing impaired populations.

The main purpose of this study was to provide an independent corroboration of open-set word recognition in some of the better cochlear-implant patients. These included the Chorimac, Nucleus (one group from the U.S.A. and one group from Hannover, Germany), Symbion, Duren/Cologne and 3M/Vienna implants. Three experiments are reported: (1) word recognition in word lists and in sentences; (2) environmental sound perception, and (3) gap detection. On word recognition, the scores of 6 Chorimac patients averaged 2.5% words and 0.7% words in sentences correct in the French tests. In the German tests, the scores averaged 17% words and 10% words in sentences for 10 Duren/Cologne patients, 15% words and 16% words in sentences for 9 3M/Vienna patients, and 10% words and 16% words in sentences (3% to 26%) for 10 Nucleus/Hannover patients. In the English tests, the scores averaged 11% words and 29.6% words in sentences for l0 Nucleus-U.S.A. patients, and 13.7% words and 35.7% words in sentences for the 9 Symbion patients. The ability to recognize recorded environmental sounds was measured with a closed set of 18 sounds. Performance averaged 23% correct for Chorimac patients, 41% correct for 3M/Vienna patients, 44% correct for Nucleus/Hannover patients, 21% correct for Duren/Cologne patients, 58% correct for Nucleus/U.S.A. patients, and 83% correct for Symbion patients. A multidimensional scaling analysis suggested that patients were, in part, utilizing information about the envelope and about the periodic/aperiodic nature of some of the sounds. Gap detection thresholds with a one-octave wide noise centered at 500 Hz varied widely among patients. Typically, patients with gap thresholds less than 40 ms showed a wide range of performance on speech perception tasks, whereas patients with gap-detection thresholds greater than 40 ms showed poor word recognition skills.

Split Attention ◽

Software Group

When students are required to learn a new computer application program, frequently they need to split their attention between material in a manual and material on the screen because neither is self-contained. Previous work has indicated that split-attention can interfere with learning because the need to mentally integrate material imposes an extraneous cognitive load. Alternatively, even if the screen-based material is self-contained, the material of a redundant manual, if processed by learners, can also impose an extraneous cognitive load. Under these circumstances, learning may be facilitated by the use of self-contained, screen-based material alone. In Experiment 1, the first author developed a windows spreadsheet, computer-based training package with an integrated format, to test these hypotheses. The split-attention effect was investigated by comparing the performance of a group of students using the integrated computer-based training software with that of a group using a conventional manual plus the computer software to be learned. The redundancy effect was investigated by comparing a group using the computer-based training software with a group using the same computer-based training software plus a hard-copy of this training software. Results from Experiment 1 supported the above cognitive load hypotheses. Specifically, in areas of high information complexity, the integrated computer-based training software group clearly outperformed both the conventional manual plus computer software group, and the computer-based training software plus hard-copy group, thus demonstrating both split-attention and redundancy effects. Experiment 2 partially replicated this result, as well as providing support for a cognitive load explanation of results by measuring mental load. In the light of these findings and previous research, it is suggested that cognitive load is a major factor in all aspects of instructional design. Computer training software that reduces extraneous cognitive load by adopting integrated computer-based training formats can considerably facilitate learning.

Student Input

The feasibility and effectiveness of teaching performance skills using a computer-based training (CBT) methodology were investigated. Graphic simulations of the appearance and functions of a system in an anti-submarine aircraft were presented to students within an instructional framework. Programmed logics controlled the dynamic representations of the equipment in response to student input made through a touch panel. The objective was to determine whether CBT could be used for low cost, part-task training. The performance of CBT students, as measured on a high fidelity simulator, was compared to that of students who had gone through conventional training consisting of workbook study and hands-on practice in the simulator. Results showed that CBT students performed the necessary skills as well before practice in the simulator as conventionally trained students could after this practice. The theoretical and cost implications are discussed.
