Kadlaskar, Girija; Seidl, Amanda; Tager-Flusberg, Helen; Nelson, Charles A.; Keehn, Brandon – Journal of Autism and Developmental Disorders, 2019
Atypical response to tactile input is associated with greater socio-communicative impairments in individuals with autism spectrum disorder (ASD). The current study examined overt orienting to caregiver-initiated touch in 12-month-olds at high risk for ASD (HRA) with (HRA+) and without (HRA-) a later diagnosis of ASD compared to low-risk comparison…

Pecukonis, Meredith; Plesa Skwerer, Daniela; Eggleston, Brady; Meyer, Steven; Tager-Flusberg, Helen – Journal of Autism and Developmental Disorders, 2019
Numerous studies have investigated the predictors of language in pre-verbal toddlers and verbally fluent children with autism spectrum disorder (ASD). The present study investigated the concurrent relations among expressive language and a set of empirically-selected social communication variables--joint attention, imitation, and play--in a unique…

Perdue, Katherine L.; Edwards, Laura A.; Tager-Flusberg, Helen; Nelson, Charles A. – Journal of Autism and Developmental Disorders, 2017
We investigated heart rate (HR) in infants at 3, 6, 9, and 12 months of age, at high (HRA) and low (LRC) familial risk for ASD, to identify potential endophenotypes of ASD risk related to attentional responses. HR was extracted from functional near-infrared spectroscopy recordings while infants listened to speech stimuli. Longitudinal analysis…

Edwards, Laura A.; Wagner, Jennifer B.; Tager-Flusberg, Helen; Nelson, Charles A. – Journal of Autism and Developmental Disorders, 2017
In this study, we investigated neural precursors of language acquisition as potential endophenotypes of autism spectrum disorder (ASD) in 3-month-old infants at high and low familial ASD risk. Infants were imaged using functional near-infrared spectroscopy while they listened to auditory stimuli containing syllable repetitions; their neural…

Lazenby, DeWayne C.; Sideridis, Georgios D.; Huntington, Noelle; Prante, Matthew; Dale, Philip S.; Curtin, Suzanne; Henkel, Lisa; Iverson, Jana M.; Carver, Leslie; Dobkins, Karen; Akshoomoff, Natacha; Tagavi, Daina; Nelson, Charles A., III; Tager-Flusberg, Helen – Journal of Autism and Developmental Disorders, 2016
Little is known about early language development in infants who later develop autism spectrum disorder (ASD). We analyzed prospective data from 346 infants, some of whom were at high risk for developing ASD, to determine if language differences could be detected at 12 months of age in the infants who later were diagnosed with ASD. Analyses…

Gabard-Durnam, Laurel; Tierney, Adrienne L.; Vogel-Farley, Vanessa; Tager-Flusberg, Helen; Nelson, Charles A. – Journal of Autism and Developmental Disorders, 2015
An emerging focus of research on autism spectrum disorder (ASD) targets the identification of early-developing ASD endophenotypes using infant siblings of affected children. One potential neural endophenotype is resting frontal electroencephalogram (EEG) alpha asymmetry, a metric of hemispheric organization. Here, we examined the development of…

Talbott, Meagan R.; Nelson, Charles A.; Tager-Flusberg, Helen – Journal of Autism and Developmental Disorders, 2015
We examined the home-based concerns reported by mothers of infant siblings of children with autism across the first year of life. At all three ages measured, mothers of high-risk infants were significantly more likely than mothers of low-risk infants to report language, social communication, and restricted and repetitive behavior concerns but were…

Shield, Aaron; Meier, Richard P.; Tager-Flusberg, Helen – Journal of Autism and Developmental Disorders, 2015
We report the first study on pronoun use by an under-studied research population, children with autism spectrum disorder (ASD) exposed to American Sign Language from birth by their deaf parents. Personal pronouns cause difficulties for hearing children with ASD, who sometimes reverse or avoid them. Unlike speech pronouns, sign pronouns are…

Talbott, Meagan R.; Nelson, Charles A.; Tager-Flusberg, Helen – Journal of Autism and Developmental Disorders, 2015
Impairments in language and communication are an early-appearing feature of autism spectrum disorders (ASD), with delays in language and gesture evident as early as the first year of life. Research with typically developing populations highlights the importance of both infant and maternal gesture use in infants' early language development.…

Chita-Tegmark, Meia; Arunachalam, Sudha; Nelson, Charles A.; Tager-Flusberg, Helen – Journal of Autism and Developmental Disorders, 2015
To explore how being at high risk for autism spectrum disorder (ASD), based on having an older sibling diagnosed with ASD, affects word comprehension and language processing speed, 18-, 24- and 36-month-old children, at high and low risk for ASD were tested in a cross-sectional study, on an eye gaze measure of receptive language that measured how…

Olu-Lafe, Olufemi; Liederman, Jacqueline; Tager-Flusberg, Helen – Journal of Autism and Developmental Disorders, 2014
There is considerable debate about whether people with autism spectrum disorder (ASD) are biased toward local information and whether this disrupts their ability to integrate two complex shapes elements into a single figure. Moreover, few have examined the relationship between integration ability and ASD symptom severity. Adolescent/adult males…

Grossman, Ruth B.; Tager-Flusberg, Helen – Journal of Autism and Developmental Disorders, 2012
Data on emotion processing by individuals with ASD suggest both intact abilities and significant deficits. Signal intensity may be a contributing factor to this discrepancy. We presented low- and high-intensity emotional stimuli in a face-voice matching task to 22 adolescents with ASD and 22 typically developing (TD) peers. Participants heard…

We performed cerebellum segmentation and parcellation on magnetic resonance images from right-handed boys, aged 6-13 years, including 22 boys with autism [16 with language impairment (ALI)], 9 boys with Specific Language Impairment (SLI), and 11 normal controls. Language-impaired groups had reversed asymmetry relative to unimpaired groups in…

Luyster, Rhiannon J.; Kadlec, Mary Beth; Carter, Alice; Tager-Flusberg, Helen – Journal of Autism and Developmental Disorders, 2008
One of the primary diagnostic criteria for the diagnosis of autism spectrum disorders (ASD) is the presence of a language delay or impairment. Children with ASD are now being identified at significantly younger ages, and prior research has consistently found that early language skills in this population are heterogeneous and an important predictor…

Smith, Leann E.; Seltzer, Marsha Mailick; Tager-Flusberg, Helen; Greenberg, Jan S.; Carter, Alice S. – Journal of Autism and Developmental Disorders, 2008
The present study examined the impact of autism symptoms and coping strategies on the well-being of mothers of children with autism spectrum disorder (ASD). The sample consisted of 153 mothers of toddlers and 201 mothers of adolescents drawn from two ongoing, longitudinal studies of families of individuals with ASD. For mothers of toddlers, lower…
