Future Advances In The Early Detection Of Reading Risk: Subgroups, Dynamic Relations, And Advanced Methodologies: Epilogue To Journal Of Learning Disabilities Special Edition “Advances In The Early Detection Of Reading Risk”, Tiffany Hogan, Jennifer M. Thomson Jan 2009

Future Advances In The Early Detection Of Reading Risk: Subgroups, Dynamic Relations, And Advanced Methodologies: Epilogue To Journal Of Learning Disabilities Special Edition “Advances In The Early Detection Of Reading Risk”, Tiffany Hogan, Jennifer M. Thomson

Department of Special Education and Communication Disorders: Faculty Publications

Six studies and 1 synthesis focused on early identification of reading impairment in this special edition. A familiar theme emerged: reading involves multiple subsystems that dynamically interact across development making early identification a ‘moving target’ (cf Speece, 2005). Based on the cumulative findings presented in this edition, we pose 5 key considerations for future advances in the early detection of reading risk: (a) attention to the definition of ‘reading’ and the heterogeneity of poor readers (b) longitudinal dynamic relations, (c) application of advanced, theory-driven methodology and statistical models, (d) early identification that leads to prescriptive early intervention, (e) early identification …


Early Speech Motor Development: Cognitive And Linguistic Considerations, Ignatius S. B. Nip, Jordan R. Green, David B. Marx Jan 2009

Early Speech Motor Development: Cognitive And Linguistic Considerations, Ignatius S. B. Nip, Jordan R. Green, David B. Marx

Department of Special Education and Communication Disorders: Faculty Publications

This longitudinal investigation examines developmental changes in orofacial movements occurring during the early stages of communication development. The goals were to identify developmental trends in early speech motor performance and to determine how these trends differ across orofacial behaviors thought to vary in cognitive and linguistic demands (i.e., silent spontaneous movements, babble, and first words). Movements of the lower lip and jaw were recorded using a three-dimensional motion capture system. Twenty-four infants were observed every 3 months, from 9 to 21 months of age. Jaw and lower lip speed, and lower lip range of movement increased with age. Silent spontaneous …

Accuracy Assessment For Ag500, Electromagnetic Articulograph, Yana Yunusova, Jordan R. Green, Antje Mefferd

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: The goal of this article was to evaluate the accuracy and reliability of the AG500 (Carstens Medizinelectronik, Lenglern, Germany), an electromagnetic device developed recently to register articulatory movements in three dimensions. This technology seems to have unprecedented capabilities to provide rich information about time-varying positions of articulators. However, strengths and weaknesses of the system need to be better understood before the device is used for speech research.
Method: Evaluations of the sensor positions over time were obtained during (a) movements of the calibration device, (b) manual movements of sensors in a cartridge within the recording field of the cube, …


Central Pattern Generation Involved In Oral And Respiratory Control For Feeding In The Term Infant, Steven M. Barlow Jan 2009

Central Pattern Generation Involved In Oral And Respiratory Control For Feeding In The Term Infant, Steven M. Barlow

Department of Special Education and Communication Disorders: Faculty Publications

Purpose of review—Drinking and eating are essential skills for survival and benefit from the coordination of several pattern generating networks and their musculoskeletal effectors to achieve safe swallows. Oral-pharyngo-esophageal motility develops during infancy and early childhood, and is influenced by various factors, including neuromuscular maturation, dietary and postural habits, arousal state, ongoing illnesses, congenital anomalies, and the effects of medical or surgical interventions. Gastroesophageal reflux is frequent in neonates and infants, and its role in neonatal morbidity including dysphagia, chronic lung disease, or apparent life-threatening events is not well understood. This review highlights recent studies aimed at understanding the development …


Oral And Respiratory Control For Preterm Feeding, Steven M. Barlow Jan 2009

Oral And Respiratory Control For Preterm Feeding, Steven M. Barlow

Department of Special Education and Communication Disorders: Faculty Publications

Purpose of review—Feeding competency is a frequent and serious challenge to the neonatal intensive care unit survivors and to the physician–provider–parent teams. The urgency of effective assessment and intervention techniques is obviated to promote safe swallow, as attainment of oral feeding for the preterm infant/newborn is one of the prerequisites for hospital discharge. If left unresolved, feeding problems may persist into early childhood and may require management by pediatric gastroenterologists and feeding therapists. This review highlights studies aimed at understanding the motor control and development of nonnutritive and nutritive suck, swallow, and coordination with respiration in preterm populations.

Recent findings—Functional …


Nonparticipatory Stiffness In The Male Perioral Complex, Shin-Ying Chu, Steven M. Barlow, Jaehoon Lee Jan 2009

Nonparticipatory Stiffness In The Male Perioral Complex, Shin-Ying Chu, Steven M. Barlow, Jaehoon Lee

Department of Special Education and Communication Disorders: Faculty Publications

Purpose—The objective of this study was to extend previous published findings in the authors’ laboratory using a new automated technology to quantitatively characterize nonparticipatory perioral stiffness in healthy male adults.

Method—Quantitative measures of perioral stiffness were sampled during a nonparticipatory task using a computer-controlled linear motor servo programmed to impose a series of tensile displacements over a span of approximately 24 mm at the oral angle in 20 healthy young male adults. Perioral electromyograms were simultaneously sampled to confirm nonparticipation or passive muscle state. Perioral stiffness, derived as a quotient from resultant force (ΔF) and oral span (ΔX), was modeled …


Task Specificity In Early Oral Motor Development, Erin M. Wilson, Jordan R. Green, Yana Y. Yunusova, Christopher A. Moore Nov 2008

Task Specificity In Early Oral Motor Development, Erin M. Wilson, Jordan R. Green, Yana Y. Yunusova, Christopher A. Moore

Department of Special Education and Communication Disorders: Faculty Publications

This article addresses a long-standing clinical and theoretical debate regarding the potential relationship between speech and nonspeech behaviors in the developing system. The review is motivated by the high popularity of nonspeech oral motor exercises (NSOMEs), including alimentary behaviors such as chewing, in the treatment of speech disorders in young children. The similarities and differences in the behavioral characteristics, sensory requirements, and task goals for speech and nonspeech oromotor behaviors are compared. Integrated theoretical paradigms and empirical data on the development of early oromotor behaviors are discussed. Although the efficacy of NSOMEs remains empirically untested at this time, studies of …

Convergent Validity Of The Early Childhood Behavior Problem Screening Scale  , Annette Griffith, J. Ron Nelson, Michael Epstein, Bjorn Pederson

Department of Special Education and Communication Disorders: Faculty Publications

This study examined the convergent validity of the parent and teacher versions of the Early Childhood Behavior Problem Screening Scale (ECBPSS) with the Child Behavior Checklist (CBCL) and the Caregiver-Teacher Report Form (C-TRF), respectively. Data were collected on a sample of preschool and kindergarten students (n = 149) from two medium-sized cities in the Midwest. Analyses of both the parent and teacher versions of the ECBPSS were corre¬lated with the corresponding Internalizing, Externalizing, and Total Problem scale scores of the CBCL and the C-TRF. The present findings and future research directions and limitations are discussed.


Academic Processing Speed Mediates The Influence Of Both Externalizing Behavior And Language Skills On The Academic Skills Of Students With Emotional Disturbance, Gregory J. Benner, J. Ron Nelson, Jill H. Allor, Paul Mooney, Tao Dai Mar 2008

Academic Processing Speed Mediates The Influence Of Both Externalizing Behavior And Language Skills On The Academic Skills Of Students With Emotional Disturbance, Gregory J. Benner, J. Ron Nelson, Jill H. Allor, Paul Mooney, Tao Dai

Department of Special Education and Communication Disorders: Faculty Publications

The results from previous research suggest that there is a relatively small (albeit statistically significant) relationship between the externalizing behavior and academic skills of students with emotional disturbance (ED). Researchers have also found that the majority of these students have language deficits that hinder their academic performance. The purposes of this study were to investigate the mediating role of academic processing speed (i.e., academic fluency) on the relationship between: (a) The externalizing behavior and academic skills of K-12 students with ED; and (b) language skills and academic skills of students with ED. Results indicate that academic processing speed mediated the …

This study describes the academic, social, and behavioral performance of elementary and secondary students with emotional and behavioral disorders (EBD) receiving services in a self-contained school for students with serious behavior problems, with an emphasis on how school adjustment and problem behavior patterns predict academic performance. Results revealed that elementary and secondary group scores were well below the 25th percentile on reading, math, and written expression measures. Further, a seven variable model representing academic, social, and behavioral domains was able to differentiate between age groups explaining 54% of the variance and correctly classifying 78.26% (n = 18) of the …


Pacifier Stiffness Alters The Dynamics Of The Suck Central Pattern Generator, Emily Zimmerman, Steven M. Barlow Jan 2008

Pacifier Stiffness Alters The Dynamics Of The Suck Central Pattern Generator, Emily Zimmerman, Steven M. Barlow

Department of Special Education and Communication Disorders: Faculty Publications

Variation in pacifier stiffness on non-nutritive suck (NNS) dynamics was examined among infants born prematurely with a history of respiratory distress syndrome. Three types of silicone pacifiers used in the NICU were tested for stiffness, revealing the Super Soothie™ nipple is 7 times stiffer than the Wee™ or Soothie™ pacifiers even though shape and displaced volume are identical. Suck dynamics among 20 preterm infants were subsequently sampled using the Soothie™ and Super Soothie™ pacifiers during follow-up at approximately 3 months of age. ANOVA revealed significant differences in NNS cycles/min, NNS amplitude, NNS cycles/burst, and NNS cycle periods as a function …

Department of Special Education and Communication Disorders: Faculty Publications

Purpose of review: In the past few years, otologists have been seeing an increasing number of patients with vestibular disorders due to migraine- associated vestibulopathy. This article reviews some of the latest developments in the understanding of this disease process, specifically its incidence, symptoms, diagnosis, and treatment.
Recent findings: Migraine-associated vestibular symptoms may include episodic true vertigo, movement-provoked dysequilibrium, imbalance/unsteadiness, and complaints of lightheadedness. The pathophysiology of migraine-associated vestibulopathy is not completely understood; however, both peripheral and central deficits have been observed. Although the International Headache Society classification does not include migraine-associated vestibulopathy as a subclassification of migraine, there is …


Regional Volumetric Change Of The Tongue During Mastication In Pigs, Z. J. Liu, B. Yamamura, V. Shcherbatyy, Jordan R. Green Jan 2008

Regional Volumetric Change Of The Tongue During Mastication In Pigs, Z. J. Liu, B. Yamamura, V. Shcherbatyy, Jordan R. Green

Department of Special Education and Communication Disorders: Faculty Publications

Structure and movement of the tongue have been studied extensively, but little study has been carried on its 3D deformation and ensuing volumetric changes during various functions. The purpose of this study is to investigate the volumetric changes of a regional section of the tongue during feeding. Four 12-week-old Yucatan miniature pigs were used. During natural mastication and water drinking, the width, length, thickness and volumetric changes were measured using six implanted ultrasonic crystals, which circumscribed a wedge-shaped volume in the region of the tongue body. Jaw movements were videotaped and digitized. Signals from these two sources were synchronized to …

Babbling, Chewing, And Sucking: Oromandibular Coordination At 9 Months, Roger W. Steeve, Christopher A. Moore, Jordan R. Green, Kevin J. Reilly, Jacki Ruark Mcmurtrey

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: The ontogeny of mandibular control is important for understanding the general neurophysiologic development for speech and alimentary behaviors. Prior investigations suggest that mandibular control is organized distinctively across speech and nonspeech tasks in 15-month-olds and adults and that, with development, these extant forms of motor control primarily undergo refinement and rescaling. The present investigation was designed to evaluate whether these coordinative infrastructures for alimentary behaviors and speech are evident during the earliest period of their co-occurrence.
Method: Electromyographic (EMG) signals were obtained from the mandibular muscle groups of 15 typically developing 9-month-old children during sucking, chewing, and speech.
Results: …

Respiratory Treatment History Predicts Suck Pattern Stability In Preterm Infants, Meredith Poore, Steven M. Barlow, Jingyan Wang, Mereditch Estep, Jaehoon Lee

Department of Special Education and Communication Disorders: Faculty Publications

Sensory deprivation and motor restriction associated with extensive oxygen therapy may lead to poor oromotor control in preterm infants. Non-nutritive suck is one of the first complex oromotor behaviors infants perform. This study determined the spatiotemporal variability of non-nutritive suck (NNS) pressure trajectories in three preterm groups with differing oxygen histories—one control group with minimal or no O2 therapy, and two Respiratory Distress Syndrome (RDS) groups with either a mild/moderate (RDS1) or moderate/severe (RDS2) O2 history. The Non-nutritive Suck Spatiotemporal Index (NNS STI) quantifies spatial and temporal variability across kinematic trajectories, and was calculated from digital representations of …

Vestibular-Evoked Myogenic Potentials, Julie A. Honaker, Ravi N. Samy

Department of Special Education and Communication Disorders: Faculty Publications

Purpose of review: This article reviews the literature on vestibular-evoked myogenic potential testing, a short latency electromyogram evoked by high acoustic stimuli and recorded via surface electrodes over the sternocleidomastoid muscle. Applications and refinements of this technique are described for different pathologies and in adults and children.
Recent findings: Various techniques for electrode placement have been described to elicit a vestibular-evoked myogenic potential response, which has been clinically investigated in normal individuals, under pathological conditions, and in adult and pediatric patients. As vestibular-evoked myogenic potential amplitude is linearly related to the level of background activity of the sternocleidomastoid …


Modulation Of The Trigeminofacial Pathway During Syllabic Speech, Meredith Estep, Steven M. Barlow Jan 2007

Modulation Of The Trigeminofacial Pathway During Syllabic Speech, Meredith Estep, Steven M. Barlow

Department of Special Education and Communication Disorders: Faculty Publications

The human orofacial system is richly endowed with low threshold, slowly adapting mechanoreceptors that respond to self-generated movements and external loads. The functional linkage between these afferents and the recruitment of motor units in the lower face during the dynamics of speech is unknown. Mechanically evoked activity in the orbicularis oris muscles was studied in young human female adults (N=10) during a lip force recruitment task associated with the repetition of the nonsense speech utterance “ah-wah.” This speech task involved the recruitment of perioral motor units against an elastic load. A skin contactor probe coupled to a servo-controlled linear motor …

Factor Structure, Internal Consistency, And Interrater Reliability Of The Early Childhood Behavior Problem Screening Scale, J. Ron Nelson, Michael Epstein, Annette Griffith, John Hopper

Department of Special Education and Communication Disorders: Faculty Publications

The current study examined the initial psychometrics of the Early Childhood Behavior Problem Screening Scale (ECBPSS; Epstein & Nelson, 2006), namely the factor structure and associated internal consistency of factor items of parent and teacher versions as well as interrater reliability. Data came from samples of preschool- and kindergarten- age children from 2 medium-size cities in the U.S. midwest. Separate analyses of the parent and teacher data revealed internalizing and externalizing factors, with Cronbach’s alphas ranging from .83 to .95. Parent and teacher interrater reliability coefficients ranged from .32 to .37. Overall, the results suggest that the 12-item ECBPSS Parent …


Risk Factors Predictive Of The Problem Behavior Of Children At Risk For Emotional And Behavioral Disorders, J. Ron Nelson, Scott Stage, Kristin Duppong-Hurley, Lori Synhorst, Michael H. Epstein Jan 2007

Risk Factors Predictive Of The Problem Behavior Of Children At Risk For Emotional And Behavioral Disorders, J. Ron Nelson, Scott Stage, Kristin Duppong-Hurley, Lori Synhorst, Michael H. Epstein

Department of Special Education and Communication Disorders: Faculty Publications

Logistic regression analyses were used to establish the most robust set of risk factors that would best predict borderline/clinical levels of problem behavior (i.e., a t score at or above 60 on the Child Behavior Checklist Total Problem scale) of kindergarten and first-grade children at risk for emotional and behavioral disorders. Results showed that among the 11 risk factor domains considered, 5 were most predictive of borderline/clinical levels of problem behavior: externalizing behavior pattern, internalizing behavior pattern, early childhood child maladjustment, family functioning, and maternal depression. Within these 5 domains, the most robust set of individual risk factors were difficult …


Fostering The Development Of Vocabulary Knowledge And Reading Comprehension Though Contextually-Based Multiple Meaning Vocabulary Instruction, J. Ron Nelson, Scott A. Stage Jan 2007

Fostering The Development Of Vocabulary Knowledge And Reading Comprehension Though Contextually-Based Multiple Meaning Vocabulary Instruction, J. Ron Nelson, Scott A. Stage

Department of Special Education and Communication Disorders: Faculty Publications

The primary purpose of this study was to assess the effects of contextually-based multiple meaning (i.e., words with multiple meanings) vocabulary instruction on the vocabulary knowledge and reading comprehension of students. Third and 5th grade students received either contextually-based multiple meaning vocabulary instruction embedded in the standard language arts instruction offered to all students over a three-month period or the standard language arts instruction alone (i.e., non-specific treatment). Students who received the contextually-based multiple meaning instruction generally showed statistically and educationally significant gains in their vocabulary knowledge and reading comprehension relative to students who did not. These gains were most …


Estimating Mandibular Motion Based On Chin Surface Targets During Speech, Jordan R. Green, Erin M. Wilson, Yu-Tsai Wang, Christopher A. Moore Jan 2007

Estimating Mandibular Motion Based On Chin Surface Targets During Speech, Jordan R. Green, Erin M. Wilson, Yu-Tsai Wang, Christopher A. Moore

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: The movement of the jaw during speech and chewing has frequently been studied by tracking surface landmarks on the chin. However, the extent to which chin motions accurately represent those of the underlying mandible remains in question. In this investigation, the movements of a pellet attached to the incisor of the mandible were compared with those of pellets attached to different regions of the chin.
Method: Ten healthy talkers served as participants. Three speaking contexts were recorded from each participant: word, sentence, and paragraph. Chin position errors were estimated by computing the standard distance between the mandibular …

Spontaneous Facial Motility In Infancy: A 3d Kinematic Analysis, Jordan R. Green, Erin M. Wilson

Department of Special Education and Communication Disorders: Faculty Publications

Early spontaneous orofacial movements have rarely been studied experimentally, though the motor experiences gained from these behaviors may influence the development of motor skills emerging for speech. This investigation quantitatively describes developmental changes in silent, spontaneous lip and jaw movements from 1 to 12 months of age using optically based 3D motion capture technology. Twenty-nine typically developing infants at five ages (1, 5, 7, 9, and 12 months) were studied cross-sectionally. Infants exhibited spontaneous facial movements at all ages studied. Several age-related changes were detected in lip and jaw kinematics: the occurrence of spontaneous movements increased, movement speed increased, the …


Interrelationships Among Language Skills, Externalizing Behavior, And Academic Fluency And Their Impact On The Academic Skills Of Students With Ed, J. Ron Nelson, Gregory J. Benner, Stern Neill, Scott A. Stage Jan 2006

Interrelationships Among Language Skills, Externalizing Behavior, And Academic Fluency And Their Impact On The Academic Skills Of Students With Ed, J. Ron Nelson, Gregory J. Benner, Stern Neill, Scott A. Stage

Department of Special Education and Communication Disorders: Faculty Publications

There is growing interest in understanding the factors that influence the academic achievement of students with emotional disturbance (ED). Structural equation modeling was used to test the interrelationships among language skills, externalizing behavior, and academic fluency and their impact on the academic skills of students with ED. Results showed that language skills exerted a significant proximal effect and distal effect on academic skills. The effect of language skills was mediated through academic fluency (path coefficient = .389) but also had a proximal effect on academic skills (path coefficient = .359). However, externalizing behavior failed to have a statistically significant effect …


Coordinative Organization Of Lingual Propulsion During The Normal Adult Swallow, Erin M. Wilson, Jordan R. Green Jan 2006

Coordinative Organization Of Lingual Propulsion During The Normal Adult Swallow, Erin M. Wilson, Jordan R. Green

Department of Special Education and Communication Disorders: Faculty Publications

Lingual propulsion during swallowing is characterized by the sequential elevation of the anterior, middle, and dorsal regions of the tongue. Although lingual discoordination underlies many swallowing disorders, the coordinative organization of lingual propulsion during the typical and disordered swallow is poorly understood. The purpose of this investigation was to quantitatively describe the coordinative organization of lingual propulsion during the normal adult swallow. Tongue movement data were obtained from the X-Ray Microbeam Database at the University of Wisconsin. Movement of four pellets placed on specific tongue regions were tracked in 36 healthy adult participants while they swallowed 10 cc of water …


Differentiating Phonotactic Probability And Neighborhood Density In Adult Word Learning, Holly L. Storkel, Jonna Armbrüster, Tiffany Hogan Jan 2006

Differentiating Phonotactic Probability And Neighborhood Density In Adult Word Learning, Holly L. Storkel, Jonna Armbrüster, Tiffany Hogan

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: The purpose of this study was to differentiate effects of phonotactic probability, the likelihood of occurrence of a sound sequence, and neighborhood density, the number of words that sound similar to a given word, on adult word learning. A second purpose was to determine what aspect of word learning (viz., triggering learning, formation of an initial representation, or integration with existing representations) was influenced by each variable.
Method: Thirty-two adults were exposed to 16 nonwords paired with novel objects in a story context. The nonwords orthogonally varied in phonotactic probability and neighborhood density. Learning was measured following 1, 4, …

Transitioning From Analog To Digital Audio Recording In Childhood Speech Sound Disorders, Lawrence D. Shriberg, Jane L. Mcsweeny, Bruce E. Anderson, Thomas F. Campbell, Michael R. Chial, Jordan R. Green, Katherina K. Hauner, Christopher A. Moore, Heather L. Rusiewicz, David L. Wilson

Department of Special Education and Communication Disorders: Faculty Publications

Few empirical findings or technical guidelines are available on the current transition from analog to digital audio recording in childhood speech sound disorders. Of particular concern in the present context was whether a transition from analog- to digital-based transcription and coding of prosody and voice features might require re-standardizing a reference database for research in childhood speech sound disorders. Two research transcribers with different levels of experience glossed, transcribed, and prosody-voice coded conversational speech samples from eight children with mild to severe speech disorders of unknown origin. The samples were recorded, stored, and played back using representative analog and digital …
