Studies of children's consistency of word production allow identification of speech sound disorder. Inconsistent errors are reported for two groups of children: childhood apraxia of speech (CAS) due to difficulty with the motoric precision and consistency of speech movements; and inconsistent phonological disorder (IPD) attributed to impaired phonological planning. This paper describes the inconsistent productions of children with IPD in comparison to typically developing children. In two studies of suspected SSD (N = 135), 22 children pronounced ≥40% of 25 words inconsistently on three repeated trials. No participant had symptoms of CAS. They were monolingual and spoke Australian- or Irish-English. Assessment determined the proportions of words said consistently (i.e. the same across productions: all correct or with the same error) or inconsistently (i.e. differently across productions: at least one correct and one error or different errors in productions). Qualitative analyses examined error types and explored the effect of target words' characteristics on inconsistency. Children with IPD produced 52% of words with different errors. While 56% of all phoneme errors were developmental (age appropriate or delayed), atypical errors typified inconsistency: default sounds and word structure errors. Words with more phonemes, syllables and consonant clusters were vulnerable to inconsistency, but their frequency of occurrence had no effect. TD children and those with IPD had different quantitative and qualitative error profiles, confirming IPD as a diagnostic category of SSD. Qualitative analyses supported the hypothesised deficit in phonological planning of words' production for children with IPD. [ABSTRACT FROM AUTHOR]

Purpose: Written clinical reflection is frequently used in speech-language pathology training programs to develop student clinical skills. The aim of this study was to explore speech-language pathology students' perceptions towards written clinical reflection. Method: Seventy-two undergraduate speech-language pathology students completed an online survey. An observational research design was undertaken. Descriptive statistics were used to analyse quantitative data. Inductive content analysis was used for qualitative data analysis. Result: Speech-language pathology students reported that written clinical reflections are useful but also wanted to explore alternative ways to reflect. Most students used written clinical reflection to focus on self-improvement of clinical skills and a small number of students used reflection to consider stakeholders' points of view. Students wanted more guidance and feedback on written clinical reflections. Conclusion: The results indicate that written clinical reflection is a useful learning tool. To facilitate the development of reflection skills in speech-language pathology students, it is important to explicitly teach clinical reflection in university curricula and to receive guidance from professional practice educators.

Most children born preterm are considered neurologically normal and free of disability. However in follow-up studies at school age, preterm children, born without major impairment, have been shown to have lower cognitive abilities and associated academic, social and behavioural difficulties. This study investigated the literacy, phonological awareness and language abilities of 169 preterm (lesser than 33 weeks gestational age) and 141 fullterm born children aged between 5 and 12 years. Reading, spelling, phonological awareness skills, language and cognitive skills were assessed. The results indicate the preterm children were significantly poorer across all domains assessed in comparison to their fullterm classmates. However, the results of the preterm children do not significantly differ to the standardised assessment populations. Spelling was particularly vulnerable in preterm children and a higher number were identified with speech difficulties. The study also provided further evidence for the strong relationship that exists between language ability, phonological skills and literacy. (Contains 9 tables and 1 figure.)

Most children's speech difficulties are "functional" (i.e. no known sensory, motor or intellectual deficits). Speech disorder may, however, be associated with cognitive deficits considered core abilities in executive function: rule abstraction and cognitive flexibility. The study compares the rule abstraction and cognitive flexibility of children with speech disorder and typically developing controls. Three groups of five-year-old children (typically developing, consistent atypical speech disorder and inconsistent speech disorder) were assessed on the Flexible Item Selection Test (Jacques and Zelazo, 2001). Children were shown a set of three cards and asked to select two that matched on one dimension (selection 1: abstraction). Children were then asked to select a different pair of cards that matched on another dimension (selection 2: flexibility). The children with consistent atypical speech disorder performed worse than the other two groups on selections 1 and 2. The children with an inconsistent speech disorder performed similarly to their typically developing peers. Children who use consistent atypical error patterns have difficulties with rule abstraction and flexibility that are not confined to the linguistic system. The results are discussed in terms of the deficits underlying different types of speech disorders. (Contains 4 tables.)

Background: In young, typically developing children, some word production variability is expected, but highly inconsistent speech is considered a clinical marker for disorder. Speech-language pathologists need to identify variability versus inconsistency, yet these terms are not clearly differentiated. Not only is it important to identify inconsistency, but also it needs to be defined and measured so that clinical decisions are evidence based. In order to understand inconsistent speech production, typical variability must be described. Aims: This paper differentiates between variability and inconsistent productions. Variability is defined as productions that differ, but can be attributed to factors described in normal acquisition and use of speech. Inconsistency is speech characterized by a high proportion of differing repeated productions with multiple error types, both segmental (phoneme) and structural errors (consonant-vowel sequence within a syllable). The study describes and quantifies the consistency of word production in typically developing children aged between 3;0 and 6;11 years. Methods and Procedures: This paper reports a large cross-sectional study (n = 409) of the consistency of children's production of words within the same linguistic context. Outcomes and Results: The study found that the speech of typically developing children is highly consistent. Children in the youngest age group demonstrated the highest levels of variability, but it remained below 13% with 10% reflecting maturational influences. Conclusions: Inconsistent production cannot be considered a typical feature of speech development. The results inform differential diagnosis of speech disorder.

The research reported investigated the efficacy of intervention, developed by a speech-language therapist and implemented by a teacher, for the language and phonological awareness (PA) abilities of pre-school, socially disadvantaged children. One study established that children from low socio-economic (SES) backgrounds had poorer skills on both measures compared to children of average SES. Half of the low SES group received language and PA intervention programmes and their progress was compared to untreated SES matched controls. Both programmes were highly effective with post-intervention performance not only exceeding that of SES controls but also equalling the performance of controls of average SES.

Background: Children with speech disorder are a heterogeneous group (e.g. in terms of severity, types of errors and underlying causal factors). Much research has ignored this heterogeneity, giving rise to contradictory intervention study findings. This situation provides clinical motivation to identify the deficits in the speech-processing chain that underlie different subgroups of developmental speech disorder. Intervention targeting different deficits should result in a differential response to intervention across these subgroups. Aims: To evaluate the effect of two different types of therapy on speech accuracy and consistency of word production of children with consistent and inconsistent speech disorder. Methods & Procedures: Eighteen children (aged 4.08-6.05 years) with severe speech disorder participated in an intervention study comparing phonological contrast and core vocabulary therapy. All children received two 8-week blocks of each intervention. Changes in consistency of production and accuracy (per cent consonants correct) were used to measure the effect of each intervention. Outcomes & Results: All of the children increased their consonant accuracy during intervention. Core vocabulary therapy resulted in greater change in children with inconsistent speech disorder and phonological contrast therapy resulted in greater change in children with consistent speech disorder. Conclusions: The results provide evidence that treatment targeting the speech-processing deficit underlying a child's speech disorder will result in efficient system-wide change. Differential response to intervention across subgroups provides evidence supporting theoretical perspectives regarding the nature of speech disorders: it reinforces the concept of different underlying deficits resulting in different types of speech disorder.

Consistency of word production contributes to carers' ability to understand children's speech. Reports of the proportion of words produced consistently by typically developing preschool children, however, vary widely from 17% to 87%. This paper examines the quantitative (consistency count) and qualitative (e.g. phonemic analysis) characteristics of word consistency in 96 children aged 36–60 months. Children named 15 pictures twice, in separate trials, in the same assessment session. The mean consistency of the production for the whole group was 82%. Older children were more consistent than younger children. Girls were more consistent than boys. Words produced correctly in one trial and in error in another may indicate resolving error patterns. Words produced in error in two different ways provided useful evidence about the nature of inconsistent word production in typically developing children. The clinical and theoretical implications are discussed. [ABSTRACT FROM AUTHOR]

This study examined spoken-word recognition in children with specific language impairment (SLI) and normally developing children matched separately for age and receptive language ability. Accuracy and reaction times on an auditory lexical decision task were compared. Children with SLI were less accurate than both control groups. Two subgroups of children with SLI, distinguished by performance accuracy only, were identified. One group performed within normal limits, while a second group was significantly less accurate. Children with SLI were not slower than the age-matched controls or language-matched controls. Further, the time taken to detect an auditory signal, make a decision, or initiate a verbal response did not account for the differences between the groups. The findings are interpreted as evidence for language-appropriate processing skills acting upon imprecise or underspecified stored representations.

Purpose: Around 9% of children have difficulty acquiring intelligible speech despite typical sensory, neuro-motor and cognitive function. Speech-language pathologists (SLPs) rely on descriptions of children's speech errors to identify speech sound disorder (SSD) and determine intervention targets and goals. Existing normative data, however, need re-evaluation to reflect changes in populations and the language learning environment. This research evaluates whether developmental phonological patterns widely accepted as describing typical acquisition predict speech errors in a recent sample of pre-school children. Method: In 2015, 99 neurotypical children aged 3;0–3;8 years;months were assessed using the Diagnostic Evaluation of Articulation and Phonology (DEAP). Their performance was compared to studies describing speech development by children of the same age for phone repertoire and phonological patterns. Result: There were differences for both measures. Phone repertoire differences were marginal, but changes in phonological pattern use were unexpected. Suppression of three developmental phonological patterns (stopping of fricatives, final consonant deletion and voicing contrasts) was delayed compared to previous norms. Atypical consonant cluster reduction, sometimes considered a marker for disorder, was observed in 10% of children. Conclusion: There were qualitative differences in the speech development of the 2015 cohort of children compared to previous developmental norms. Valid and current normative data are necessary for the accurate identification of children needing intervention. The differences we found reinforce the need for regular updating of assessment tools, as well as greater understanding of how children's language learning environments are changing and potentially influencing speech development.
