'High functioning autism' is a term often used for individuals with autism spectrum disorder without an intellectual disability. Over time, this term has become synonymous with expectations of greater functional skills and better long-term outcomes, despite contradictory clinical observations. This study investigated the relationship between…

Purpose: The purpose of this study was to investigate the relationship of the grunt vocalizations to cognitive and expressive language status in children with disabilities. Children with typical development produce communicative grunts at the onset of referential word production and comprehension at 14-16 months of age and continue to use this…

The purpose of the study was to evaluate the effects of a system of least prompts procedure and use of a graphic organizer to teach the academic literacy standard of comparing characters in text for elementary students with moderate and severe intellectual disability. A multiple probe across participants design was used to evaluate the results.…

The Sustainable Development Goals mandate that by 2030, all children should have access to quality early child development opportunities, healthcare and pre-primary education. Yet validated measures of ECD in low and middle income countries (LMICs) are rare. To address this gap, a Systematic Review (SR) of measures available to profile the…

Given that early caregiver concerns may be different for children who go on to receive a diagnosis of autism spectrum disorder versus another developmental disability, early caregiver concerns may differ for girls. Using a community-based sample of children (n = 241), we examined the extent to which gender differences may be related to caregiver…

In recent years, a literature has emerged describing contributions fathers make to the development of very young children. Scholars suggest that active play may be a specific area of parenting in which fathers are primary and, further, that this type of play helps children experience intense emotions and learn to regulate them. However, this…

This study investigates the nature and the factor structure of infant intelligence. The Bayley Mental Scale items were administered. According to the analysis, intelligence at any age is a set of separate mental abilities at each age, and there are a variety of paths through which mental development occurs. (JAZ)

This study attempted to find which factors determine the course of mental growth. The hypotheses were as follows: (1) early growth rates are rapid, chaotic, and uneven; (2) intellectual functions become more complex at age 2; (3) language is of overriding importance in intellectual growth; (4) more developed individuals have a longer infancy…

The Mayes Motor Free Compilation (MMFC) assesses mental ability in young (under age 2) children with motor disabilities. This study evaluated the concurrent validity of the MMFC by administering it and the Bayley Scales of Infant Development to normal children. Findings suggest that the MMFC provides a valid estimate of mental age, even without…

This study investigated the concurrent validity of the Mayes Motor Free Compilation (MMFC) using the mental scale of the Bayley Scales of Infant Development (BSID) as the criterion variable with 50 typically developing preschool-aged children. Results indicated that the MMFC and the BSID scores were significantly and positively correlated.…

Forty-four children who had been born preterm and their mothers participated in the follow-up study. At 3 and 14 months (corrected age) cognitive development was assessed using the BOS 2-30, the Dutch version of the Bayley Scales of Infant Development. The BOS yields measures of mental and motor development. At 7.5 years, intelligence was measured…

Down Syndrome children (N=229), aged 1-83 months, from Australia, Canada, and Germany were tested using the Bayley Scales of Infant Development. Test performances on the Bayley's Mental and Motor scales were not dissimilar, leading to the conclusion that young Down Syndrome children from different countries with relatively comparable standards of…

Preschool-age children who are experiencing delays in physical, cognitive, communication, social, emotional, or adaptive development are often referred for a comprehensive assessment to make diagnostic determinations and to help develop appropriate interventions. Typically cognitive assessment has a key role in a comprehensive evaluation of a…
