Variables influencing executive functioning in preschool hearing-impaired children implanted within 24 months of age: an observational cohort study

Executive Functions (EFs) are fundamental to every aspect of life. The present study was implemented to evaluate factors influencing their development in a group of preschools orally educated profoundly deaf children of hearing parents, who received CI within two years of age.

Does early cochlear implantation promote better reading comprehension skills?

Objective
to investigate the effect of age at CI activation and to explore the role of other variables such as linguistic skills, stimulation modality and gender on reading comprehension.
Study Design
Prospective observational nonrandomized study.

The role of speech rate for Italian-speaking cochlear implant users: insights for everyday speech perception

This study investigated the effect of speech rate for Italian-speaking cochlear implant (CI) users with the aim of gaining insight into everyday listening situations where speaker’s rate may vary considerably together with speech level in fluctuating background noise. The test material was prepared by processing the Italian STARR test with temporal compression of sentence material. Twelve adult CI users were divided into two subgroups based on their STARR performance: good and poor performers. The effect of varying speech rate was remarkable for both subgroups.

Perception of lexical stress cued by low‑frequency pitch and insights into speech perception in noise for cochlear implant users and normal hearing adult

Purpose Cochlear implant (CI) users show great difficulty for understanding speech in noise and this fact may partly stem from their poor low-frequency (LF) pitch perception and temporal fine structure (TFS) processing. Clinical assessment of pitch perception is usually based on non-speech tasks. However, linguistically relevant contexts such as lexical stress may better reflect the role of pitch in speech perception, especially for everyday speech where background noise is inevitable.

Intonational cues for speech perception in noise by cochlear implant listeners

Purpose
The objectives of this study are to evaluate cochlear implant (CI) listeners’ ability to infer low frequency (LF) pitch information from temporal fine structure (TFS) cues and to gain insight into its effects on speech perception, especially in the presence of a fluctuating background noise. Pitch perception assessment using linguistic stimuli is believed to better reflect the role of pitch in communicatively realistic situations.
