Background: We describe acoustic patterns across the five most prominent vocal types in typically developing infants (TD) and compare them with patterns in infants who develop autism (ASD) or a developmental disability (DD) not related to autism. Infant-directed speech (IDS) is a potentially important influence on such vocal acoustic patterns. Both acoustic patterns and effects of IDS are important for understanding the earliest origins of communication disorders.

We looked at babies' production of babbling with mature syllables across the first year of life. Babies usually start producing mature babbling at 7 months of age before they say their first words.

- Scientists studied a genetic change called 3q29 deletion (3q29Del) which greatly increases the risk for disorders like schizophrenia and autism.
- They used brain scans to look at the cerebellum (part of the brain) in 24 people with 3q29Del and 1,608 people without, finding that those with the deletion had smaller cerebellum areas and other differences.
- The research suggests that problems in the cerebellum might be linked to how people with 3q29Del think and move, helping us understand brain issues better in these disorders.
Objective: To examine clinical correlates and prevalence of food selectivity (FS) - ie, self-restricted diet, reluctance to try new foods - in children with autism spectrum disorder (ASD) ascertained from a general outpatient autism clinic.
Study Design: A multidisciplinary team (pediatric nurse practitioner, psychologist and dietitian) assessed medical and psychosocial histories and dietary habits in 103 children with ASD (mean age = 5.8 ± 2.
The present study compared the infant's tendency in the first year of life to produce clusters of particular vocal types (squeals, vocants, and growls) in typically developing (TD) and autistic infants. Vocal clustering provides evidence of vocal category formation and may establish a foundation for speech development. Specifically, we compared the extent of vocal clustering across outcome groups and age groups.

While FXTAS is more common in males than females, females can develop the disease, and some evidence suggests that patterns of impairment may differ across sexes. Few studies include females with symptoms of FXTAS, and as a result, little information is available on key phenotypes for tracking disease risk and progression in female premutation carriers.

Methods: A retrospective chart review examining records of a large cohort of autistic children (N = 746) referred for ASD evaluation was conducted.
