“…Linck, Hoshino, and Kroll (2008) similarly demonstrated that efficient inhibitory control abilities on the Simon task were associated with decreased cognate activation and facilitation on a picture naming task. Thus, during production, inhibition may help bilinguals hone in on language-specific phonetic realizations of cognates (Nip & Blumenfeld, 2015). Increased cognitive control may dampen access of irrelevant-language phonotactic constraints in order to select the relevant language.…”

The current study examines the relation between cognitive control and linguistic competition resolution at the sublexical level in bilinguals. Twenty-one Spanish-English bilinguals and 23 English monolinguals completed a non-linguistic Stroop task (indexing inhibitory control) and a linguistic priming/lexical decision task (indexing Spanish phonotactic constraint competition during English comprehension). More efficient Stroop performance (i.e., a smaller Stroop effect) in bilinguals was associated with decreased competition from Spanish phonotactic constraints during English comprehension. This relation was observed when nonword targets overlapped in phonotactic constraints and phonological form with preceding cognate primes (e.g., prime: stable (Spanish: estable)/target: esteriors). Findings suggest a link between non-linguistic cognitive control and co-activation of linguistic structures at the sublexical level in bilinguals.

“…Power spectrum of the F0 was derived by the fast Fourier transformation (FFT) of the re‐sampled F0 contour in cent for obtaining the F0 modulation extent at individual frequency. Based on our previous research, the spectral power of F0 variability were categorised into a low‐frequency band (0.2 to 3 Hz, LFP), a middle‐frequency band (3 to 8 Hz, MFP) and a high‐frequency band (8 to 25 Hz, HFP).The extent of modulation in each band within the defined range was summated and expressed in decibels (dB) as the following equation, and the 0 dB was referred to the modulation power of 1 cent

P = 10 \times \log_{10} false(\sum_{n = f s}^{fn} I_{n} false)

“…Moreover, the disruption of a competent audio‐vocal feedback would affect the variability and/or fluctuations of vocal fundamental frequency (F0), vocal pitch, speech fluency, etc, and these variations may result in a greater risk of voice problems. In our previous studies, power spectral analysis of F0 of a sustained vowel was used to examine the interactions between the auditory feedback system and the vocal motor control . The results reported that the F0 fluctuations of lower than 3 Hz became significantly greater either when the auditory feedback of their own voices was greatly masked by noise in the healthy individuals or for the sustained vowel vocalisations of the patients with hearing impairment .…”

Objective Increasing evidence supports that auditory feedback of one's own voice closely relates to real‐time adjustments of vocal control. Previous studies highlighted that the low‐frequency modulations of below 3 Hz (LFM) embedded in vocal fundamental frequency (F0) showed a reflex‐like response to altered auditory inputs. However, the auditory feedback control of different vocal disorders remains unclear. Design A cross‐sectional, case‐controlled study. Setting A tertiary medical centre. Participants Sustained vocalisations of vowel/a/ from adult healthy controls and patients with vocal fold nodules, vocal fold polyps and vocal fold cysts, respectively. The vocalisations were made at a comfortable pitch and at the intensity of 70 ~ 80 dBC under the following four auditory conditions: natural hearing, 90‐dBC speech noise, 10‐dBC enhanced feedback of self‐produced voice and both the noise and voice feedback. Main outcome measures Power spectral analysis of F0 contour of sustained vowel. Results Patients with vocal fold nodules presented with different audio‐vocal feedback behaviour and audio‐vocal response to speech noise from the other two vocal pathologies of vocal fold polyp and vocal fold cyst as well as the healthy controls (P < .001, one‐way ANOVA). Conclusion The vocal fold nodules may be not only a vocal fold disease but also a disease caused by abnormal audio‐vocal feedback. Moreover, the distinct audio‐vocal feedback of vocal fold nodules could be revealed by power spectral analysis of vocal fundamental frequencies. Although further investigations are necessary, adjustments of audio‐vocal feedback behaviour may provide a new insight and benefit to the treatment of vocal fold nodules in the future.

“…CIs have been highly successful for children with severe-to-profound hearing loss, offering potential for mainstreamed education and auditory-oral communication. Despite this, a significant number of recipients still experience poor speech understanding and language delay, and, even among the best performers, restoration to normal auditory fidelity is rare (2-3). This is due, in part, to several well-known issues with electrical stimulation that prevent CIs from accurately simulating natural acoustic hearing.…”

Hypothesis Image-guided cochlear implant (CI) programming can improve hearing outcomes for pediatric CI recipients. Background CIs have been highly successful for children with severe-to-profound hearing loss, offering potential for mainstreamed education and auditory-oral communication. Despite this, a significant number of recipients still experience poor speech understanding, language delay, and, even among the best performers, restoration to normal auditory fidelity is rare. While significant research efforts have been devoted to improving stimulation strategies, few developments have led to significant hearing improvement over the past two decades. Recently introduced techniques for image-guided CI programming (IGCIP) permit creating patient-customized CI programs by making it possible, for the first time, to estimate the position of implanted CI electrodes relative to the nerves they stimulate using CT images. This approach permits identification of electrodes with high levels of stimulation overlap and to deactivate them from a patient’s map. Prior studies have shown that IGCIP can significantly improve hearing outcomes for adults with CIs. Methods The IGCIP technique was tested for 21 ears of 18 pediatric CI recipients. Participants had long-term experience with their CI (5 months-13 years) and ranged in age from 5-17 years old. Speech understanding was assessed after approximately 4 weeks of experience with the IGCIP map. Results Using a two-tailed Wilcoxon signed-rank test, statistically significant improvement (p<0.05) was observed for word and sentence recognition in quiet and noise as well as pediatric self-reported quality of life (QOL) measures. Conclusion Our results indicate that image-guidance significantly improves hearing and QOL outcomes for pediatric CI recipients.
