“…Each movement bout was identified and the presence of cooccurring vocalizations noted. Rhythmic movements were further classified on the basis of involved body segment(s) (e.g., both legs, right arm, head, torso) and form (see Iverson & Fagan, 2004, …”

“…When systems of this type are coupled, they are typically termed 'coupled oscillators;' and it is a well-established characteristic of coupled oscillators that each tries to draw the other into its characteristic oscillation pattern. This suggests the possibility that entrainment, which occurs when the activation of one oscillator is sufficient to "pull in" the activity of the other to yield an ordered patterning of coordinated activity, may characterize the development of vocal-motor coordination (see Iverson & Fagan, 2004, for discussion and relevant data; see also Ejiri & Masataka, 2001). Iverson and Thelen (1999) characterize the emergence of reduplicated babble as a product of the entrainment of the vocal by the motor system.…”

In this study we examined early motor, vocal, and communicative development in a group of younger siblings of children diagnosed with autism (Infant Siblings). Infant Siblings and no-risk comparison later-born infants were videotaped at home with a primary caregiver each month from 5 to 14 months, with follow-up at 18 months. As a group, Infant Siblings were delayed in the onset of early developmental milestones and spent significantly less time in a greater number of postures, suggestive of relative postural instability. In addition, they demonstrated attenuated patterns of change in rhythmic arm activity around the time of reduplicated babble onset; and they were highly likely to exhibit delayed language development at 18 months.

“…Relação entre desenvolvimento motor amplo e linguagem tem sido reportada [7,8,34]. Pesquisas também evidenciam que quando a criança já é capaz de sentar e andar, observam-se incrementos no vocabulário expressivo [34], e que vocalizações rítmicas são mais prevalentes em crianças que apresentam movimento rítmico [8].…”

ABSTRACT AIMS: To evaluate the acquisition of motor milestones in the first two years of life and the relationship between gross motor function and manipulation, cognition and language in infants who attend day care centers. METHODS: Cross-sectional study with a non-probabilistic sample of infants attending public and private day care centers in a city in southern Brazil. The Alberta Infant Motor Scale and the Bayley Scales of Infant and Toddler Development were used to assess the motor performance of each child. Descriptive statistics were used for the characterization of the sample and simple linear regression in three different age groups (group 1: between six and nine months; group 2: between 10 and 12 months; group 3: between 13 and 16 months) for the analysis of relationships between the variables gross and fine motor skills, cognition and language. RESULTS: We studied 63 infants between six and 16 months of age who did not present statistically significant differences in their biological and sociodemographic characteristics when the three stratified groups were compared. Most children did not acquire the developmental milestones in the period expected for their age group. There was correlation between the developmental scores, and the gross motor function was able to explain a large part of the variability in the fine motor function, cognition and language scores (R 2 ajust>0.5) over the first two years of life. CONCLUSIONS: The evaluated motor skills occurred generally late in the sample. The delay in the acquisition of gross motor milestones had an impact on the overall developmental skills, corroborating the influence of gross motor function in the other domains of development.KEY WORDS: infant development; motor skills; infant; child day care center.

“…Verbal abilities have been found to correlate with both nonverbal cognitive and nonverbal motor skills. For example, motor control and coordination have been found to be strongly associated with pre-verbal vocalizations in infants (Ejiri & Masataka, 2001;Iverson & Fagan, 2004) and language-based measures in adults (Carello, LeVasseur, & Schmidt, 2002). This dissertation focuses specifically on nonverbal cognitive abilities.…”

who always told me I could accomplish anything I set my mind to. The first aim of this dissertation was to determine whether early deafness is related to children's nonverbal cognitive abilities. Performance of a group of deaf infants were compared to that of same-aged hearing infants on visual sequence learning (VSL) and visual recognition memory (VRM) tasks. The hypothesis was that if deafness is negatively related to general cognitive ability, then the deaf infants would perform more poorly than same-aged hearing infants on the two tasks. There were no significant differences in VSL (n = 19) or VRM (n = 13) performance between the two groups (Chapter Ill). These results are inconclusive due to the small sample sizes, but importantly, there were individual infants in both groups who demonstrated learning on the two nonverbal tasks.The second aim was to determine whether VSL and VRM ability can provide predictive information about spoken language development. The results for the normalhearing 8.S-month-olds provide evidence for a significant relation between VSL ability and spoken language outcomes (Chapter IV). Specifically, it was found that sequence learning (thought to rely on procedural memory ability) may contribute to vocabulary and gestural development in normal-hearing infants. Further research with larger samples of v infants is needed to determine whether procedural learning may be important for grammar acquisition.These results suggest that VSL ability may not be related to spoken language outcomes for deaf infants who use cochlear implants (Chapter V), although VRM ability may be (Chapter VI). If this pattern of results held up for a larger sample of deaf infants, this would suggest that the nonverbal cognitive abilities tapped in the VSL and VRM tasks are not critical for at least some aspects of spoken language development in deaf children who use cochlear implants, and that potential deficits in nonverbal cognitive ability are not necessarily associated with poorer spoken language ability in this population. In future research a larger sample of deaf infants should be recruited in order to clarify whether nonverbal cognitive skills are related to early deafness, and how those nonverbal skills might relate to spoken language development in this unique population.vi
