Objectives: This study aims to measure, at two time points, the relationship between self-perceived global stress and the personality traits of the mothers of children who have central auditory processing disorder (APD) and compare it with the results from mothers of typically developing (TD) children. The comparisons were made before the COVID-19 pandemic, as well as late in the pandemic.

Methods: The level of stress was assessed using the Perceived Stress Scale (PSS-10), while the Short Big Five Markers (IPIP-BFM-20) were used to assess Big Five personality traits.

This study looked at the possible effect of the COVID-19 pandemic on individuals who came to our clinic seeking relief from tinnitus. The performance of the subjects during the COVID-19 pandemic was compared with similar individuals who came to our clinic before the pandemic began. The study involved 50 adults with chronic tinnitus, made up of a study group (24 subjects tested during the COVID-19 pandemic of 2020-2021) and a control group before the pandemic began (26 subjects tested from 2013 to 2017).

The medial olivocochlear (MOC) system is thought to be responsible for modulation of peripheral hearing through descending (efferent) pathways. This study investigates the connection between peripheral hearing function and auditory attention tasks of different degrees of difficulty. Peripheral hearing function was evaluated by analyzing the amount of change in otoacoustic emissions (OAEs) by contralateral acoustic stimulation (CAS), a well-known effect of the MOC system.

Several studies have suggested that distortion product otoacoustic emissions (DPOAEs) may be an early marker not only of hearing loss (HL) but also of tinnitus. The purpose of this study was to investigate whether DPOAEs measured up to 16 kHz are affected by the presence of tinnitus. Pure tone thresholds and DPOAEs were measured in two groups: 55 patients with tinnitus and 63 subjects without tinnitus.

Purpose: To investigate the relationship between self-perceived global stress and the personality traits of mothers of children with central auditory processing disorders (APD), and make a comparison with mothers of typically developing (TD) children.

Design And Methods: A cross-sectional study using two questionnaires - the Perceived Stress Scale (PSS-10) and the Short Big Five Markers (IPIP-BFM-20) - to assess five personality dimensions: extraversion, agreeableness, conscientiousness, emotional stability, and intellect/imagination. The study material included 187 mothers, of whom 108 were mothers of children with APD.

Objectives: Hearing is one of our most important senses, and hearing ability has an enormous impact on a child's psychomotor development. Children with auditory perception disorders may show abnormal development in terms of speech, language, and communication skills, as well as other disorders involving the cognitive sphere, social-emotional interactions, and motor development. This paper describes different paths of psychomotor development in three 4-year-old children.

Background: There is little research into the relationship between a deaf child's developmental outcomes and their mother's self-perceived parental role. The aim of this study was to find out whether the different levels of global psychomotor development in young deaf children who had a cochlear implant (CI), or were candidates for a CI, were related to particular family factors: the self-perceived parental role and the family quality of life (FQoL) as gauged by their hearing mothers, as well as the child's sociodemographic and deafness-related factors and the sociodemographic characteristics of the mothers.

Methods: The study was conducted on a group of 64 children with bilateral severe or profound sensorineural hearing loss (SNHL) who were CI users (36 children) or qualified for cochlear implantation (28 children) and their hearing mothers.

The medial olivocochlear (MOC) system is thought to be responsible for modulation of peripheral hearing through descending (efferent) pathways. This study investigated the connection between peripheral hearing function and conscious attention during two different modality tasks, auditory and visual. Peripheral hearing function was evaluated by analyzing the amount of suppression of otoacoustic emissions (OAEs) by contralateral acoustic stimulation (CAS), a well-known effect of the MOC.

Objectives: A cochlear implant (CI) has the potential to improve the functioning of a deaf child in many aspects. Nevertheless, the dynamics of the general development, beyond the typically measured language abilities, directly after CI, is still unknown, especially if a child is implanted early. In this study we present a methodological framework for assessment of different domains of development, as well as the central auditory nervous system (CANS) maturation in infants and toddlers with a CI.

Background: Previous studies indicate that many different aspects of attention are impaired in children diagnosed with developmental dyslexia (DD). The objective of the present study was to identify cognitive profiles of DD on the basis of attentional test performance.

Material/methods: 78 children with DD (30 girls, 48 boys, mean age of 12 years ±8 months) and 32 age- and sex-matched non-dyslexic children (14 girls, 18 boys) were examined using a battery of standardized tests of reading, phonological and attentional processes (alertness, covert shift of attention, divided attention, inhibition, flexibility, vigilance, and visual search).

Background: The neural underpinnings of auditory information processing have often been investigated using the odd-ball paradigm, in which infrequent sounds (deviants) are presented within a regular train of frequent stimuli (standards). Traditionally, this paradigm has been applied using either high temporal resolution (EEG) or high spatial resolution (fMRI, PET). However, used separately, these techniques cannot provide information on both the location and time course of particular neural processes.

Introduction: The objective of the presented study was to develop and evaluate a P300 experimental protocol for simultaneous registration of event-related potentials (ERPs) and functional MRI (fMRI) data with continuous imaging. It may be useful for investigating attention and working memory processes in specific populations, such as children and neuropsychiatric patients.

Materials And Methods: Eleven children were investigated with simultaneous ERP-fMRI.

Introduction: Processing of auditory information in central nervous system bases on the series of quickly occurring neural processes that cannot be separately monitored using only the fMRI registration. Simultaneous recording of the auditory evoked potentials, characterized by good temporal resolution, and the functional magnetic resonance imaging with excellent spatial resolution allows studying higher auditory functions with precision both in time and space.

The Aim Of The Study: was to implement the simultaneous AEP-fMRI recordings method for the investigation of information processing at different levels of central auditory system.
