The Impact

Purpose The primary purpose of this study was to examine the effect of sentence length on speech rate and its characteristics, articulation rate and pauses, in typically developing children. Method Sixty-two typically developing children between the ages of 10 and 14 years repeated sentences varying in length from two to seven words. Dependent variables included speech rate (syllables per second), articulation rate (syllables per second), and proportion of time spent pausing. Results Speech rate and articulation rate significantly increased with increases in sentence length, but proportion of time spent pausing did not increase with sentence length. There were no significant main effects of age. Conclusions This is the first study to suggest that sentence length differentially impacts the component parts of speech rate, articulation rate and pause time. Increases in sentence length led to increases in speech rate, primarily due to increases in articulation rate and not increases in pause time. Articulation rate appears to be highly sensitive to the impact of sentence length, while a higher cognitive–linguistic load may be required to see sentence length effects on pause time.

Communicative Efficiency

Purpose This article describes the developmental trajectories of four communication-related parameters (i.e., intelligibility, articulation rate, fluency, and communicative efficiency) in a cross-sectional study of typically developing children between 3 and 9 years. The four target parameters were related to auditory-perceptual parameters of speech function. Method One hundred forty-four typically developing children (ages 3;0–9;11 [years;months]; 72 girls and 72 boys) participated. Speech samples were collected using the materials of the Bogenhausen Dysarthria Scales for Childhood Dysarthria, a German assessment tool for childhood dysarthria, and analyzed following established auditory-perceptual criteria on relevant speech functions. To assess intelligibility, naïve listeners transcribed sentences repeated by the children. Articulation rate and fluency were measured by acoustic analyses; communicative efficiency was determined by multiplying the proportion of correctly transcribed syllables by speech rate. Results Intelligibility showed a steep developmental trajectory, with the majority of children obtaining a proportion of intelligible syllables close to 1.0 at the age of 5 years. Articulation rate demonstrated a flatter trajectory, with high variability still within the older children. Disfluencies, on the contrary, occurred only in the youngest children. By definition, communicative efficiency shared the characteristics of intelligibility and rate curves. A principal component analysis revealed, among other findings, strong connections between intelligibility and articulation, as well as between communicative efficiency, articulation, and rate measures. Conclusions While children speak intelligibly, in terms of the applied assessment, at a comparably young age, other communication-relevant parameters show a slower developmental progress. Knowledge on the typical development of communication-related parameters and on their complex relationships with functional speech variables is crucial for the clinical assessment of childhood dysarthria.

Communicative Success

Speech rate (articulation rate and pauses) was examined for its relation to communicative success. Native English speakers (NSs) were paired with other NSs and with non-native speakers (NNSs). The subjects viewed a short film, the content of which they were to relay to their two partners independently. Communicative success was measured through comprehension questions addressed to the listeners at the completion of the task. Analyses indicated that although a slight majority of NSs slowed their speech rate for NNSs, they did not adjust articulation rate, but did significantly increase pause time. Neither speech rate nor articulation rate varied over the course of the narrations. Contrary to intuition, the subjects who successfully communicated the story to NNSs did not adjust their speech rate, while those who had difficulty communicating with NNSs increased pause time significantly. The implications of the findings are discussed, and suggestions for further research are made.

The Impact

The exclusion of high-motion participants can reduce the impact of motion in functional Magnetic Resonance Imaging (fMRI) data. However, the exclusion of high-motion participants may change the distribution of clinically relevant variables in the study sample, and the resulting sample may not be representative of the population. Our goals are two-fold: 1) to document the biases introduced by common motion exclusion practices in functional connectivity research and 2) to introduce a framework to address these biases by treating excluded scans as a missing data problem. We use a study of autism spectrum disorder to illustrate the problem and the potential solution. We aggregated data from 545 children (8-13 years old) who participated in resting-state fMRI studies at Kennedy Krieger Institute (173 autistic and 372 typically developing) between 2007 and 2020. We found that autistic children were more likely to be excluded than typically developing children, with 29.1% and 16.1% of autistic and typically developing children excluded, respectively, using a lenient criterion and 80.8% and 59.8% with a stricter criterion. The resulting sample of autistic children with usable data tended to be older, have milder social deficits, better motor control, and higher intellectual ability than the original sample. These measures were also related to functional connectivity strength among children with usable data. This suggests that the generalizability of previous studies reporting naïve analyses (i.e., based only on participants with usable data) may be limited by the selection of older children with less severe clinical profiles because these children are better able to remain still during an rs-fMRI scan. We adapt doubly robust targeted minimum loss based estimation with an ensemble of machine learning algorithms to address these data losses and the resulting biases. The proposed approach selects more edges that differ in functional connectivity between autistic and typically developing children than the naïve approach, supporting this as a promising solution to improve the study of heterogeneous populations in which motion is common.

Imitation skills play a crucial role in social cognitive development from early childhood. Many studies have shown a deficit in imitation skills in children with Autism Spectrum Disorders (ASD). Little is known about the development of imitation behaviors in children with ASD. This study aims to measure the trajectories of early imitation skills in preschoolers with ASD and how these skills impact other areas of early development. For this purpose, we assessed imitation, language and cognition skills in 177 children with ASD and 43 typically developing children (TD) aged 2 to 5 years old, 126 of which were followed longitudinally, yielding a total of 396 time-points. Our results confirmed the presence of an early imitation deficit in toddlers with ASD compared to TD children. The study of the trajectories showed that these difficulties were marked at the age of two years, and gradually decreased until the age of 5 years old. Imitation skills were strongly linked with cognitive, language skills and level of symptoms in our ASD group at baseline. Moreover, the imitation skills at baseline were predictive of the language gains a year later in our ASD group. Using a data-driven clustering method, we delineated different developmental trajectories of imitation skills within the ASD group. The clinical implications of the findings are discussed, particularly the impact of an early imitation deficit on other areas of competence of the young child.

Purpose: We aimed to develop normative growth curves for articulation rate during sentence repetition for typically developing children. Our primary goal was the development of quantile/percentile growth curves, so that typical variation in articulation rate with age could be estimated. We also estimated when children became adultlike in their articulation rate and we examined the contributions of age and utterance length to articulation rate.Method: This cross-sectional study involved collection of in-person speech samples from 570 typically developing children (297 girls; 273 boys) who passed speech, language, and hearing screening measures. Pauses greater than 150 ms in duration were removed from the samples, and articulation rate was measured in syllables per second (sps).Results: Articulation rate reliably increased with age and utterance length. Rate in all key percentiles increased with age. The median rate (50th percentile) increased from 2.7 sps at 36 months to 3.3 sps at 96 months. The 5th percentile increased from 2.3 to 3.1 sps over the same age range. Using 3.2 sps as a benchmark for adultlike speech, we found the 25th, 50th, and 75th percentiles reached adultlike rates at 99, 75, and 53 months, respectively.Conclusions: Articulation rate increases from early childhood into middle childhood, and it is generally adultlike by 10 years of age. Variability in articulation rate among typical children was substantial. Implications for prior research and for clinical usage are discussed.

The Impact

Many children with typical development are highly sedentary, overweight/obese, and are deemed not ready for school at kindergarten entry. All of these concerns can be related to a lack of movement skill proficiency in this population. The purpose of this narrative review was to synthesize the literature examining the impact of movement skills on 5 areas of overall health: physical activity, physical fitness, body composition, self-beliefs, and executive functioning. To gain an understanding of these relationships, only studies employing an experimental or observational longitudinal design were reviewed. Although the results were limited in the number of studies available, there is evidence that movement skill may have a positive influence on these broad domains of health both naturally over the course of development and through intervention. We recommend that a universal approach to movement skill development is warranted, given the range of benefits that stem from developing proficiency in these skills.

Target Children

The sleep patterns of 45 mothers of children with moderate to severe multiple disabilities, 45 mothers of children with Down syndrome, and 45 mothers of typically developing children were compared by means of a 7-day diary. The children ranged in age from 6 months to 5 years. The Caregiver's Activity and Recording of Events (CARE) Inventory was completed by each subject to record mothers' activities in half-hour segments throughout a 24-hour day. Activities were coded into nine categories including rest/sleep. The three groups of mothers were compared on total hours of rest/sleep per day, number of sleep interruptions, reason for sleep interruptions, influences of siblings of target children, and number of times the father attended to the target child during the night as perceived by the mother. Surprisingly, the results indicated that mothers of children with multiple disabilities reported more sleep than did mothers in the other two groups. There were no significant differences found among the groups in the following: amount of weekly daytime sleep; frequency and duration of child-related interruptions per week; number of nights of uninterrupted sleep per week; maximum number of sleep interruptions in one night; and mothers' perception of fathers' nighttime assistance. The data indicated that many mothers in all three groups experienced numerous weekly sleep interruptions, particularly mothers of infants 6 to 12 months of age. Professionals working with mothers of young children must consider the effects of shortened and interrupted sleep patterns on the day time functioning and health of mothers and the effect on the well-being of the entire family.

The Impact

ABSTRACTFast mapping weaknesses in children with specific language impairment (SLI) may be explained by differences in disambiguation, mapping an unknown word to an unnamed object. The impact of language ability and linguistic stimulus on disambiguation was investigated. Sixteen children with SLI (8 preschool, 8 school-age) and sixteen typically developing age-matched children selected referents given familiar and unfamiliar object pairs in three ambiguous conditions: phonologically distinct word (PD), phonologically similar word (PS), no word (NW). Preschoolers with SLI did not disambiguate, unlike typically developing age-matched participants, who consistently selected unfamiliar objects given PD. School-age children with SLI disambiguated given PD. Delays in disambiguation for young children with SLI suggest limitations in processes that facilitate word learning for typically developing children. School-age children with SLI consistently selected familiar objects for PS, unlike typically developing children, suggesting differences in phonological activation for word learning.
