The role of stimulus-locked spike timing is important for representation of stimulus periodicity, low frequency spectrum, and spatial location.

Despite this difference in performance, the results from the group of CI adult users who have acquired hearing impairment after head trauma show the effectiveness of auditory rehabilitation through cochlear implantation in these situations.Ī processing scheme for speech signals is proposed that emulates synchrony capture in the auditory nerve. However, the difference was not statistically significant for most tests. The performance of the group of CI adult users who have acquired hearing impairment after head trauma was globally lower than that observed on the group of hearing impairment with other etiologies.

Statistically significant difference was found for consonantal phonemes identification test, 100 words through the telephone test, monosyllables test (when analyzed regarding the phonemes correctly repeated), and sentences through the telephone test. No statistically significant difference was found for most tests. Average results from group 1 were lower when compared with those of group 2 in all the tests used. Performance was assessed using the following tests: tonal audiometry, speech audiometry, consonantal phonemes identification test, 100 words test, 100 words through the telephone test, monosyllables test, numbers test, sentences test, and sentences through the telephone test. The participants were divided into two groups: group 1 (N = 14) composed of CI adult users who have acquired severe to profound hearing loss after head trauma group 2 (N = 231) composed of CI adult users who have severe to profound hearing loss from other etiologies. In this paper, the authors analyze the auditory rehabilitation after cochlear implantation in adults with hearing impairment after head trauma, comparing their performance with that of other cochlear implant (CI) adult users who have post-lingual hearing impairment with other etiologies. It is therefore crucial to distinguish between in-principle abilities (even when they reflect default proce. In contrast, listeners’ decision for how long to delay categorization, we find, is a function of perceptual ambiguity. We also find that maintenance seems to be the default, neither limited to perceptually particularly ambiguous signals, nor a learned strategy specific to our experiment. In two perception experiments, we find no limit in the ability to maintain subcategorical information. We argue that previous work might have over-interpreted the role of these limitations.

At the same time, previous work suggests that finite sensory memory or processing capacity strongly limits how much subcategorical information can be maintained (or for how long). Optimal cue integration thus requires maintenance of subcategorical information over time. Acoustic and contextual cues to linguistic categories (e.g., phonemes or words) tend to be temporally distributed across the speech signal.
