This paper presents follow-up longitudinal data to research that previously suggested the possibility of abnormal gaze behavior marked by decreased eye contact in a subgroup of 6-month-old infants at risk for autism (Merin, Young, Ozonoff & Rogers, 2007). Using eye-tracking data and behavioral data recorded during a live mother-infant interaction involving(More)
Gross motor development (supine, prone, rolling, sitting, crawling, walking) and movement abnormalities were examined in the home videos of infants later diagnosed with autism (regression and no regression subgroups), developmental delays (DD), or typical development. Group differences in maturity were found for walking, prone, and supine, with the DD and(More)
OBJECTIVE To examine prospectively the emergence of behavioral signs of autism in the first years of life in infants at low and high risk for autism. METHOD A prospective longitudinal design was used to compare 25 infants later diagnosed with an autism spectrum disorder (ASD) with 25 gender-matched low-risk children later determined to have typical(More)
Thirty-one infant siblings of children with autism and 24 comparison infants were tested at 6 months of age during social interaction with a caregiver, using a modified Still Face paradigm conducted via a closed-circuit TV-video system. In the Still Face paradigm, the mother interacts with the infant, then freezes and displays a neutral, expressionless(More)
Prospective studies of infants at risk for autism spectrum disorder have provided important clues about the early behavioural symptoms of autism spectrum disorder. Diagnosis of autism spectrum disorder, however, is not currently made until at least 18 months of age. There is substantially less research on potential brain-based differences in the period(More)
BACKGROUND Patient navigation (PN) has been suggested as a way to reduce cancer health disparities; however, many models of PN exist and most have not been carefully evaluated. The goal of this study was to test the Ohio American Cancer Society model of PN as it relates to reducing time to diagnostic resolution among persons with abnormal breast, cervical,(More)
This prospective study examined object exploration behavior in 66 12-month-old infants, of whom nine were subsequently diagnosed with an autism spectrum disorder. Previous investigations differ on when the repetitive behaviors characteristic of autism are first present in early development. A task was developed that afforded specific opportunities for a(More)
We investigated whether deficits in social gaze and affect and in joint attention behaviors are evident within the first year of life among siblings of children with autism who go on to be diagnosed with autism or ASD (ASD) and siblings who are non-diagnosed (NoASD-sib) compared to low-risk controls. The ASD group did not differ from the other two groups at(More)
OBJECTIVE To examine the incidence, severity, and factors related to posttraumatic stress disorder (PTSD) symptoms in parents of pediatric solid organ transplant recipients. METHOD A total of 170 caregivers of pediatric transplant recipients completed self-report measures of psychological functioning between 10 and 38 months after their child's most(More)
BACKGROUND Many athletic maneuvers involve coordination of movement between the lower and upper extremities, suggesting that better core muscle use may lead to improved athletic performance and reduced injury risk. PURPOSE To determine to what extent a training program with quasistatic trunk stabilization (TS) exercises would improve measures of core(More)
