Effectiveness of the Kaufman Speech to Language Protocol for Children With Childhood Apraxia of Speech and Comorbidities When Delivered in a Dyadic and Group Format.

Purpose: The current study is a Phase I clinical study with the goal of determining feasibility and the effectiveness of the Kaufman Speech to Language Protocol (K-SLP) for children with childhood apraxia of speech (CAS) and comorbidities. We hypothesized that K-SLP intervention would result in improved outcomes and maintenance of treatment effect at 3-4 months postintervention.

Method: Single-subject experimental design with multiple baselines across behaviors was replicated across a group of six children.

Decoding kinematic information from beta-band motor rhythms of speech motor cortex: a methodological/analytic approach using concurrent speech movement tracking and magnetoencephalography.

Introduction: Articulography and functional neuroimaging are two major tools for studying the neurobiology of speech production. Until now, however, it has generally not been feasible to use both in the same experimental setup because of technical incompatibilities between the two methodologies.

Methods: Here we describe results from a novel articulography system dubbed Magneto-articulography for the Assessment of Speech Kinematics (MASK), which is technically compatible with magnetoencephalography (MEG) brain scanning systems.

Predictors of Functional Communication Outcomes in Children With Idiopathic Motor Speech Disorders.

Purpose: The purpose of the study was to investigate child- and intervention-level factors that predict improvements in functional communication outcomes in children with motor-based speech sound disorders.

Method: Eighty-five preschool-age children with childhood apraxia of speech ( = 37) and speech motor delay ( = 48) participated. Multivariable logistic regression models estimated odds ratios and 95% confidence intervals for the association between minimal clinically important difference in the Focus on the Outcomes of Communication Under Six scores and multiple child-level (e.

Cross-Modal Somatosensory Repetition Priming and Speech Processing.

Background: Motor speech treatment approaches have been applied in both adults with aphasia and apraxia of speech and children with speech-sound disorders. Identifying links between motor speech intervention techniques and the modes of action (MoA) targeted would improve our understanding of how and why motor speech interventions achieve their effects, along with identifying its effective components. The current study focuses on identifying potential MoAs for a specific motor speech intervention technique.

Speech Kinematics and Coordination Measured With an MEG-Compatible Speech Tracking System.

Articulography and functional neuroimaging are two major tools for studying the neurobiology of speech production. Until recently, however, it has generally not been possible to use both in the same experimental setup because of technical incompatibilities between the two methodologies. Here we describe results from a novel articulography system dubbed Magneto-articulography for the Assessment of Speech Kinematics (MASK), which we used to derive kinematic profiles of oro-facial movements during speech.

Development and Validation of a Probe Word List to Assess Speech Motor Skills in Children.

Purpose The aim of the study was to develop and validate a probe word list and scoring system to assess speech motor skills in preschool and school-age children with motor speech disorders. Method This article describes the development of a probe word list and scoring system using a modified word complexity measure and principles based on the hierarchical development of speech motor control known as the Motor Speech Hierarchy (MSH). The probe word list development accounted for factors related to word (i.

PROMPT intervention for children with severe speech motor delay: a randomized control trial.

Background: Currently, there is limited information on the intervention efficacy for children with speech motor delay (SMD). This randomized control trial (RCT) study examined the effectiveness of Prompts for Restructuring Oral Muscular Phonetic Targets (PROMPT) intervention to improve the outcomes in children with SMD. We hypothesized that children with SMD receiving PROMPT intervention would improve more in the measured outcomes than those waitlisted and receiving home training.

Speech Sound Disorders in Children: An Articulatory Phonology Perspective.

Speech Sound Disorders (SSDs) is a generic term used to describe a range of difficulties producing speech sounds in children (McLeod and Baker, 2017). The foundations of clinical assessment, classification and intervention for children with SSD have been heavily influenced by psycholinguistic theory and procedures, which largely posit a firm boundary between phonological processes and phonetics/articulation (Shriberg, 2010). Thus, in many current SSD classification systems the complex relationships between the etiology (distal), processing deficits (proximal) and the behavioral levels (speech symptoms) is under-specified (Terband et al.

Assessment of Childhood Apraxia of Speech: A Review/Tutorial of Objective Measurement Techniques.

Background With respect to the clinical criteria for diagnosing childhood apraxia of speech (commonly defined as a disorder of speech motor planning and/or programming), research has made important progress in recent years. Three segmental and suprasegmental speech characteristics-error inconsistency, lengthened and disrupted coarticulation, and inappropriate prosody-have gained wide acceptance in the literature for purposes of participant selection. However, little research has sought to empirically test the diagnostic validity of these features.

Age-Related Differences in the Perception of Emotion in Spoken Language: The Relative Roles of Prosody and Semantics.

Purpose We aim to identify the possible sources for age-related differences in the perception of emotion in speech, focusing on the distinct roles of semantics (words) and prosody (tone of speech) and their interaction. Method We implement the Test for Rating of Emotions in Speech ( Ben-David, Multani, Shakuf, Rudzicz, & van Lieshout, 2016 ). Forty older and 40 younger adults were presented with spoken sentences made of different combinations of 5 emotional categories (anger, fear, happiness, sadness, and neutral) presented in the prosody and semantics.

Investigating intervention dose frequency for children with speech sound disorders and motor speech involvement.

Background: Treatment outcome data for children with severe speech sound disorders with motor speech involvement (SSD-MSI) are derived from Phase I clinical research studies. These studies have demonstrated positive improvements in speech production. Currently there is no research examining the optimal treatment dose frequency for this population.

Does emotion matter? The role of alexithymia in violent recidivism: A systematic literature review.

Background: Several variables have been evidenced for their association with violent reoffending. Resultant interventions have been suggested, yet the rate of recidivism remains high. Alexithymia, characterised by deficits in emotion processing and verbal expression, might interact with these other risk factors to affect outcomes.

Measuring and Training Speech-Language Pathologists' Orofacial Cueing: A Pilot Demonstration.

Tactile-kinesthetic-proprioceptive (TKP) input used to facilitate speech motor control is considered an active ingredient within speech motor interventions. Objective metrics identifying skill level differences across speech-language pathologists (S-LP) providing TKP cues are crucial for monitoring treatment delivery fidelity. The study examined three kinematic measures indicating accuracy and consistency of TKP inputs by 3 S-LPs with varying experience levels (S-LP 1: novice; S-LP 2 and S-LP 3: advanced).

Children's and adults' perception of questions and statements from terminal fundamental frequency contours.

The present study compared children's and adults' identification and discrimination of declarative questions and statements on the basis of terminal cues alone. Children (8-11 years, n = 41) and adults (n = 21) judged utterances as statements or questions from sentences with natural statement and question endings and with manipulated endings that featured intermediate fundamental frequency (F) values. The same adults and a different sample of children (n = 22) were also tested on their discrimination of the utterances.

A pilot study into a possible relationship between diet and stuttering.

Purpose: There are theoretical and empirical reasons to consider a potential role for copper metabolism in the brain in how it could influence stuttering. However, a link between stuttering and dietary intake has never been researched in a systematic way. This pilot study therefore aimed to explore a possible association between ingested amounts of copper and thiamine (vitamin B1) with stuttering frequency using a double blind cross-over longitudinal paradigm.

Coupling dynamics in speech gestures: amplitude and rate influences.

Speech is a complex oral motor function that involves multiple articulators that need to be coordinated in space and time at relatively high movement speeds. How this is accomplished remains an important and largely unresolved empirical question. From a coordination dynamics perspective, coordination involves the assembly of coordinative units that are characterized by inherently stable coupling patterns that act as attractor states for task-specific actions.

Determinants of neurological disease: Synthesis of systematic reviews.

Systematic reviews were conducted to identify risk factors associated with the onset and progression of 14 neurological conditions, prioritized as a component of the National Population Health Study of Neurological Conditions. These systematic reviews provided a basis for evaluating the weight of evidence of evidence for risk factors for the onset and progression of the 14 individual neurological conditions considered. A number of risk factors associated with an increased risk of onset for more than one condition, including exposure to pesticides (associated with an increased risk of AD, amyotrophic lateral sclerosis, brain tumours, and PD; smoking (AD, MS); and infection (MS, Tourette syndrome).

Imitation of Non-Speech Oral Gestures by 8-Month-Old Infants.

This study investigates the oral gestures of 8-month-old infants in response to audiovisual presentation of lip and tongue smacks. Infants exhibited more lip gestures than tongue gestures following adult lip smacks and more tongue gestures than lip gestures following adult tongue smacks. The findings, which are consistent with predictions from Articulatory Phonology, imply that 8-month-old infants are capable of producing goal-directed oral gestures by matching the articulatory organ of an adult model.

Parent-child interaction in motor speech therapy.

Purpose: This study measures the reliability and sensitivity of a modified Parent-Child Interaction Observation scale (PCIOs) used to monitor the quality of parent-child interaction. The scale is part of a home-training program employed with direct motor speech intervention for children with speech sound disorders.

Method: Eighty-four preschool age children with speech sound disorders were provided either high- (2×/week/10 weeks) or low-intensity (1×/week/10 weeks) motor speech intervention.

Random Item Generation Is Affected by Age.

Purpose: Random item generation (RIG) involves central executive functioning. Measuring aspects of random sequences can therefore provide a simple method to complement other tools for cognitive assessment. We examine the extent to which RIG relates to specific measures of cognitive function, and whether those measures can be estimated using RIG only.

Genetic variation associated with the occurrence and progression of neurological disorders.

This paper presents an overview of genetic variation associated with the onset and progression of 14 neurological disorders, focusing primarily on association studies. The 14 disorders are heterogeneous in terms of their frequency, age of onset, etiology and progression. There is substantially less evidence on progression than onset.

Linguistic and emotional-valence characteristics of reading passages for clinical use and research.

Purpose: Fluency assessment in people who stutter (PWS) includes reading aloud passages. There is little information on properties of these passages that may affect reading performance: emotional valance, arousal, word familiarity and frequency and passage-readability. Our first goal was to present an extensive examination of these factors in three commonly used (“traditional”) passages.

The Effect of Auditory Information on Patterns of Intrusions and Reductions.

Purpose: The study investigates whether auditory information affects the nature of intrusion and reduction errors in reiterated speech. These errors are hypothesized to arise as a consequence of autonomous mechanisms to stabilize movement coordination. The specific question addressed is whether this process is affected by auditory information so that it will influence the occurrence of intrusions and reductions.

Effects of age on speech and voice quality ratings.

The quality of communication may be affected by listeners' perception of talkers' characteristics. This study examined if there were effects of talker and listener age on the perception of speech and voice qualities. Younger and older listeners judged younger and older talkers' gender and age, then rated speech samples on pleasantness, naturalness, clarity, ease of understanding, loudness, and the talker's suitability to be an audiobook reader.
