BACKGROUND: Cognitive Behaviour Therapy (CBT) is an effective treatment for childhood anxiety disorders, yet a significant proportion of children do not benefit from it. CBT for child anxiety disorders typically includes a range of strategies that may not all be applicable for all affected children. This study explored whether there are distinct subgroups of children with anxiety disorders who are characterized by their responses to measures of the key mechanisms that are targeted in CBT (i...

BACKGROUND: Myotonic dystrophy type 1 (DM1) is a slowly progressive multi-systemic disease with an autosomal-dominant inheritance caused by a mutation on chromosome 19 (19q13.3). AIMS: To explore speech characteristics in a group of individuals with the congenital and childhood-onset forms of DM1 in terms of intelligibility, speech-sound production, nasality and compensatory articulation. A further aim was to analyse whether speech characteristics were correlated to subforms of DM1 and if speech outcome could be related to muscle strength...

BACKGROUND: Aerodynamic measures of subglottic air pressure (Ps) and airflow rate (AFR) are used to select behavioral voice therapy versus surgical treatment for voice disorders. However, these measures are usually taken during a series of syllables, which differs from conversational speech. Repeated syllables do not share the variation found in even simple sentences, and patients may use their best rather than typical voice unless specifically instructed otherwise. This study examined the potential differences in estimated Ps and AFR in syllable and sentence production and their effects on a measure of vocal efficiency in normal speakers...

Background: Root cause analyses (RCA) are often completed in health care settings to determine causes of adverse events (AEs). RCAs result in action plans designed to mitigate future patient harm. National reviews of RCA reports have assessed the safety of numerous health care settings and suggested opportunities for improvement. However, few studies have assessed the safety of receiving care from physical therapists, occupational therapists, or speech and language pathology pathologists...

The arcuate fasciculus (AF) is a neural fiber tract that is critical to speech and music development. Although the predominant role of the left AF in speech development is relatively clear, how the AF engages in music development is not understood. Congenital amusia is a special neurodevelopmental condition, which not only affects musical pitch but also speech tone processing. Using diffusion tensor tractography, we aimed at understanding the role of AF in music and speech processing by examining the neural connectivity characteristics of the bilateral AF among thirty Mandarin amusics...

OBJECTIVE: Cortical malformations are documented postmortem in speech processing areas of the dyslexic human brain. The goal of this pilot study was to find out if such anatomic anomalies can be detected noninvasively and in vivo. METHODS: We developed a reconstruction of left perisylvian cortex profiles at a resolution of 400 μm using T1 data acquired with ultra-high-field MRI at 7T. Cortical thickness, myelinated cortical thickness, and layer-wise myelination were then compared in 6 men with developmental dyslexia and 6 healthy controls matched for age, sex, handedness, education level, and nonverbal IQ...

AIM: Primary lateral sclerosis (PLS) is a form of motor neuron disease involving only upper motor neurons. In some patients presenting as PLS, the disease progresses to involve lower motor neurons and thereby converting to amyotrophic lateral sclerosis (ALS). However, pure forms of PLS do exist. Our aim was to study epidemiological and clinical characteristics of pure PLS patients treated at our neuromuscular clinic. METHODS: We retrospectively reviewed 15 patients from July 2011 to October 2014 with PLS treated at the neuromuscular disorder clinic at our hospital...

BACKGROUND: Akinetic mutism is a key diagnostic feature of prion diseases, however, their rapidly progressive nature makes detailed investigation of the language disorder in a large cohort extremely challenging. This study aims to position prion diseases in the nosology of language disorders and improve early clinical recognition. METHODS: A systematic, prospective investigation of language disorders in a large cohort of patients diagnosed with prion diseases. 568 patients were included as a sub-study of the National Prion Monitoring Cohort...

Aphasia describes a spectrum of speech impairments due to damage in the language centers of the brain. Insult to the inferior frontal gyrus of the dominant cerebral hemisphere results in Broca's aphasia - the inability to produce fluent speech. The left cerebral hemisphere has historically been considered the dominant side, a characteristic long presumed to be related to a person's "handedness". However, recent studies utilizing fMRI have shown that right hemispheric dominance occurs more frequently than previously proposed and despite a person's handedness...

OBJECTIVE: The objective of this study was to evaluate if noise interferes with the vocal dose in women without vocal complaints. STUDY DESIGN: This is an experimental and comparative study. METHODS: Data were collected on 27 women between 22 and 50 years of age without vocal complaints in a university classroom. Speech-language pathology evaluation was performed employing auditory-perceptual analysis and a vocal symptom questionnaire. The acoustics of the classroom were evaluated via both observation of the characteristics of the room and the quantification of background noise and reverberation time...

Humans have an impressive, automatic capacity for identifying and organizing sounds in their environment. However, little is known about the timescales that sound identification functions on, or the acoustic features that listeners use to identify auditory objects. To better understand the temporal and acoustic dynamics of sound category identification, two go/no-go perceptual gating studies were conducted. Participants heard speech, musical instrument, and human-environmental sounds ranging from 12.5 to 200 ms in duration...

Mitsuharu Matsumoto
This study introduces a noise reduction technique that uses a complex bilateral filter. A bilateral filter is a nonlinear filter originally developed for images that can reduce noise while preserving edge information. It is an attractive filter and has been used in many applications in image processing. When it is applied to an acoustical signal, small-amplitude noise is reduced while the speech signal is preserved. However, a bilateral filter cannot handle noise with relatively large amplitudes owing to its innate characteristics...

How do children represent words? If lexical representations are based on encoding the indexical characteristics of frequently-heard speakers, this predicts that speakers like a child's own mother should be best understood. Alternatively, if they are based on the child's own motor productions, this predicts an own-voice advantage in word recognition. Here, we address this question by presenting 2.5-year-olds with recordings of their own voice, another child's voice, their own mother's voice, and another mother's voice in a child-friendly eye-tracking procedure...

Purpose: The goal of this study was to test whether fronting and lengthening of lax vowels influence the perception of femininity in listeners whose dialect is characterized as already having relatively fronted and long lax vowels in male and female speech. Method: Sixteen English words containing the /ɪ ɛ ʊ ɑ/ vowels were produced by a male speaker with 2 degrees of vowel fronting. Then, the vowel duration was manipulated in 3 steps. Thirty-nine listeners from the Southern United States judged how feminine each word sounded to them on an interval scale...

What is the social function of babbling? An important function of prelinguistic vocalizing may be to elicit parental behavior in ways that facilitate the infant's own learning about speech and language. Infants use parental feedback to their babbling to learn new vocal forms, but the microstructure of parental responses to babbling has not been studied. To enable precise manipulation of the proximal infant cues that may influence maternal behavior, we used a playback paradigm to assess mothers' responsiveness to prerecorded audiovisual clips of unfamiliar infants' noncry prelinguistic vocalizations and actions...
