“…There is considerably less agreement in both the CAS and AAS literatures on whether each disorder also includes deficits in representational processes-specifically, deficits in the precision and stability of encoding appropriately specified phonological representations of speech domains and/or deficits in memory constraining the storage and/or retrieval of representations (e.g., Chilosi et al, 2015;Nijland, Terband, & Maassen, 2015;Shriberg, Lohmeier, Strand, & Jakielski, 2012). Moreover, if deficits in appropriate specification and/or in the storage/retrieval of representations are documented in CAS, a significant question for theory and treatment is whether they are core or corollary deficits in the CAS phenotype.…”

Purpose Previous articles in this supplement described rationale for and development of the pause marker (PM), a diagnostic marker of childhood apraxia of speech (CAS), and studies supporting its validity and reliability. The present article assesses the theoretical coherence of the PM with speech processing deficits in CAS. Method PM and other scores were obtained for 264 participants in 6 groups: CAS in idiopathic, neurogenetic, and complex neurodevelopmental disorders; adult-onset apraxia of speech (AAS) consequent to stroke and primary progressive apraxia of speech; and idiopathic speech delay. Results Participants with CAS and AAS had significantly lower scores than typically speaking reference participants and speech delay controls on measures posited to assess representational and transcoding processes. Representational deficits differed between CAS and AAS groups, with support for both underspecified linguistic representations and memory/access deficits in CAS, but for only the latter in AAS. CAS–AAS similarities in the age–sex standardized percentages of occurrence of the most frequent type of inappropriate pauses ( abrupt ) and significant differences in the standardized occurrence of appropriate pauses were consistent with speech processing findings. Conclusions Results support the hypotheses of core representational and transcoding speech processing deficits in CAS and theoretical coherence of the PM's pause-speech elements with these deficits.

“…The results from the Sensory Profile Questionnaire were also compared with Kaufman Speech Praxis Test which revealed significant positive correlations between oral-motor apraxia, abnormal imitations of oral movements and abnormal repetition of simple phonemes compared with sensitivity. Nijland et al [16] found that complex sensorimotor and sequential tasks correlate significantly with the severity of the speech impairment in children with CAS indicating a comorbidity in nonverbal sequential functioning.…”

Subtypes of speech sound disorders (SSDs) with a sensorimotor origin are known as motor speech disorders (MSDs). The symptoms can be diverse, and the causes of the disorders in children are in many cases unknown. Examples of MSD are childhood apraxia of speech and dysarthria. MSD is often seen in neurodevelopmental disorders such as cerebral palsy, developmental coordination disorder (DCD) or autism spectrum disorders (ASD), or it is seen with no obvious diagnosis but usually with comorbid problems. Within all existing comorbidity dysfunctions, the motor and sensory systems are of interest for identifying possible underlying mechanisms of MSD. Namely, soft neurological signs such as hypotonia, decreased speed and low accuracy of motor skills and delayed motor development are given consideration by many researchers for better understanding of underlying motor mechanisms of MSD. Results from comorbidity studies highlight the relationship of MSD with complex sensorimotor tasks and sequential motor tasks. In this chapter, our aim is to frame findings from studies about comorbidity of sensory and motor dysfunctions in MSD in order to theorise affected mechanisms and propose an underlying global motor deficit. We will conclude with implications for therapy models.

“…Based on these premises, the Computer Articulation Instrument (CAI) was developed (Maassen et al, 2019). The CAI consists of a battery of speech production tasks and is based on a series of studies of Dutch children with developmental and acquired SSDs Nijland, Maassen, van der Meulen, Gabreëls, et al, 2003;Nijland, Terband, & Maassen, 2015;Thoonen, Maassen, Gabreels, & Schreuder, 1999;Thoonen, Maassen, Gabreëls, & Schreuder, 1994). The CAI has a modular structure and provides an interactive administration and scoring of four speech tasks.…”

Cognitive Functions in Childhood Apraxia of Speech

Abstract: These results suggest that CAS involves a symptom complex that not only comprises errors of sequencing speech movements but implicates comorbidity in nonverbal sequential functioning in most children with CAS.
