“…Since these are prime conditions for entrainment, production of repetitive, rhythmically organized arm movements gradually entrains vocal activity, leading eventually to the emergence of the rhythmically organized CV sequences that comprise babbling. One would therefore expect the appearance of reduplicated babble to be accompanied by an increase in frequency of arm rhythmicity; and indeed, this is precisely what is observed in typically developing infants (e.g., Ejiri, 1998;Iverson, 2005;Thelen, 1979).…”

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.

“…As a first step, a child forms auditory images of speech sounds. Using an internal model, the child then experiments with how to integrate the percept of a sound with the proper way to manipulate the vocal apparatus to produce the sound (babbling) (Ejiri 1998;Guenther et al 1998). If the percept of a sound is disrupted (at any level), then production of that sound would undoubtedly be affected.…”

Audio–vocal system regulation in children with autism spectrum disorders

Do children with autism spectrum disorders (ASD) respond similarly to perturbations in auditory feedback as typically developing (TD) children? Presentation of pitch-shifted voice auditory feedback to vocalizing participants reveals a close coupling between the processing of auditory feedback and vocal motor control. This paradigm was used to test the hypothesis that abnormalities in the audio-vocal system would negatively impact ASD compensatory responses to perturbed auditory feedback. Voice fundamental frequency (F 0 ) was measured while children produced an /a/ sound into a microphone. The voice signal was fed back to the subjects in real time through headphones. During production, the feedback was pitch shifted (-100 cents, 200 ms) at random intervals for 80 trials. Averaged voice F 0 responses to pitch-shifted stimuli were calculated and correlated with both mental and language abilities as tested via standardized tests. A subset of children with ASD produced larger responses to perturbed auditory feedback than TD children, while the other children with ASD produced significantly lower response magnitudes. Furthermore, robust relationships between language ability, response magnitude and time of peak magnitude were identified. Because auditory feedback helps to stabilize voice F 0 (a major acoustic cue of prosody) and individuals with ASD have problems with prosody, this study identified potential mechanisms of dysfunction in the audio-vocal system for voice pitch regulation in some children with ASD. Objectively quantifying this deficit may inform both the assessment of a subgroup of ASD children with prosody deficits, as well as remediation strategies that incorporate pitch training.

“…Masataka (1995) found the association of index finger extension with syllabic vocalizations in threemonth-old babies. In addition, other studies have shown the association of canonical babbling and rhythmic manual movements between 6 and 9 months (Ejiri, 1998;Ejiri & Masataka, 2001), or suggest a mutual facilitation effect between motor and vocal development (Iverson & Fagan 2004;Iverson, Hall, Nickel, & Wozniak, 2007). Several motor and gestural milestones coemerge with language development milestones in early development (Bates & Dick, 2002).…”

Eleven monolingual Spanish children were observed from 9 to 12 and 15 months of age in a semi-structured play situation. We obtained three main findings: (1) the use of multimodal patterns of communication increases significantly with age during the period studied; (2) the rate of use of those multimodal patterns at 12 months predicts lexical development at 15 months; and (3) the use of pointing gesture at 12 months, especially when it is accompanied of vocalization and social use of gaze, is the best predictor of lexical outcome at 15 months. Our findings support the idea that gestures, gazes and vocalizations are part of an integrated and developing system that children use flexibly to communicate from early on. The coordination of these three types of elements, especially when pointing gesture is involved, has a predictive value on early lexical development and appears as a key for progress in language development.
