Relationship Between Socioeconomic Status and Basic Auditory Processing in Young Adults.

Purpose: The current study aimed at investigating the relationship between socioeconomic status (SES) and basic auditory processing in young adults with normal hearing. Specifically, we sought to determine whether SES metrics, including parental education, parental occupation, and individual education attainment, influenced performance on tasks of basic auditory processing. Secondarily, we also aimed at understanding the interactive effects of SES and working memory on basic auditory processing.

Relationship Between Cognitive Abilities and Basic Auditory Processing in Young Adults.

Purpose: The diagnosis of auditory processing disorder (APD) is controversial particularly due to the influence of higher order factors of language and cognition on the diagnostic APD testing. As a result, there might be a need for testing for other domains (e.g.

Multi-session training in the evening schedule exhibits enhanced speech learning.

Speech learning can be influenced by a variety of factors. A growing body of literature suggests a significant influence of sleep on speech learning, i.e.

Auditory Evoked Potentials in Communication Disorders: An Overview of Past, Present, and Future.

This article provides a brief overview of auditory evoked potentials (AEPs) and their application in the areas of research and clinics within the field of communication disorders. The article begins with providing a historical perspective within the context of the key scientific developments that led to the emergence of numerous types of AEPs. Furthermore, the article discusses the different AEP techniques in the light of their feasibility in clinics.

Early Development of Neural Speech Encoding Depends on Age but Not Native Language Status: Evidence From Lexical Tone.

We investigated the development of early-latency and long-latency brain responses to native and non-native speech to shed light on the neurophysiological underpinnings of perceptual narrowing and early language development. Specifically, we postulated a two-level process to explain the decrease in sensitivity to non-native phonemes toward the end of infancy. Neurons at the earlier stages of the ascending auditory pathway mature rapidly during infancy facilitating the encoding of both native and non-native sounds.

Neural Speech Encoding in Infancy Predicts Future Language and Communication Difficulties.

Purpose This study aimed to construct an objective and cost-effective prognostic tool to forecast the future language and communication abilities of individual infants. Method Speech-evoked electroencephalography (EEG) data were collected from 118 infants during the first year of life during the exposure to speech stimuli that differed principally in fundamental frequency. Language and communication outcomes, namely four subtests of the MacArthur-Bates Communicative Development Inventories (MCDI)-Chinese version, were collected between 3 and 16 months after initial EEG testing.

An Objective Approach Toward Understanding Auditory Processing Disorder.

Purpose In the field of audiology, auditory processing disorder (APD) continues to be a topic of ongoing debate for clinicians and scientists alike, both in terms of theory and clinical practice. In the current viewpoint, we first lay out the main issues that are central to the controversy surrounding APD, and then suggest a framework toward their resolution. Method The current viewpoint is informed by reviewing existing studies in the field of APD to better understand the issues contributing to the controversies in APD.

Effect of Complexity on Speech Sound Development: Evidence From Meta-Analysis Review of Treatment-Based Studies.

In the current study, we aimed at understanding the effect of exposure to complex input on speech sound development, by conducting a systematic meta-analysis review of the existing treatment-based studies employing complex input in children with speech sound disorders. In the meta-analysis review, using a list of inclusion criteria, we narrowed 280 studies down to 12 studies. Data from these studies were extracted to calculate effect sizes that were plotted as forest plots to determine the efficacy of complexity-based treatment approaches.

Combination of absolute pitch and tone language experience enhances lexical tone perception.

Absolute pitch (AP), a unique ability to name or produce pitch without any reference, is known to be influenced by genetic and cultural factors. AP and tone language experience are both known to promote lexical tone perception. However, the effects of the combination of AP and tone language experience on lexical tone perception are currently not known.

Complexity drives speech sound development: Evidence from artificial language training.

Traditionally, learning is assumed to take place with exposure to simpler elements first followed by exposure to elements with increasing levels of difficulty. Recent reports suggest that exposure to complex elements leads to more widespread changes. However, whether learning via exposure to complex or to simple elements is more beneficial is a matter of ongoing debate.

Neural Correlates of Indicators of Sound Change in Cantonese: Evidence from Cortical and Subcortical Processes.

Across time, languages undergo changes in phonetic, syntactic, and semantic dimensions. Social, cognitive, and cultural factors contribute to sound change, a phenomenon in which the phonetics of a language undergo changes over time. Individuals who misperceive and produce speech in a slightly divergent manner (called ) contribute to variability in the society, eventually leading to sound change.

Brainstem encoding of speech and musical stimuli in congenital amusia: evidence from Cantonese speakers.

Congenital amusia is a neurodevelopmental disorder of musical processing that also impacts subtle aspects of speech processing. It remains debated at what stage(s) of auditory processing deficits in amusia arise. In this study, we investigated whether amusia originates from impaired subcortical encoding of speech (in quiet and noise) and musical sounds in the brainstem.

Validation of the Screening Test for Auditory Processing (STAP) on school-aged children.

Objectives: The present study focussed on validating the Screening Test for Auditory Processing (STAP) that contains four subsections: speech-in-noise, dichotic consonant vowel, gap detection and auditory memory. The sensitivity and specificity were ascertained by comparing the results of the screening test with that of diagnostic tests for auditory processing.

Methods: The STAP was administered on 500 school going children in the age range of 8-13 years.

Screening Test for Auditory Processing (STAP): a preliminary report.

Background: The presence of auditory processing disorder in school-age children has been documented (Katz and Wilde, 1985; Chermak and Musiek, 1997; Jerger and Musiek, 2000; Muthuselvi and Yathiraj, 2009). In order to identify these children early, there is a need for a screening test that is not very time-consuming.

Purpose: The present study aimed to evaluate the independence of four subsections of the Screening Test for Auditory Processing (STAP) developed by Yathiraj and Maggu (2012).

Comparison of a screening test and screening checklist for auditory processing disorders.

Objective: This study was carried out to determine the relationship between two screening tools to detect auditory processing disorders (APDs). The two screening tools were the screening checklist for auditory processing (SCAP) and screening test for auditory processing (STAP).

Method: Four hundred school-going children (218 males, 182 females) studying in grades III-VIII in three schools were randomly selected for the study.
