Amy Armstrong-Heimsoth; Abbey Monroe; Camryn Cupp; Nancy Potter; Mark VanDam; Beate Peter – Journal of Occupational Therapy, Schools & Early Intervention, 2024
Speech problems affect about 66% of children with classic galactosemia (CG), but limited evidence is reported on early motor and sensory motor development in this at-risk population. Research has been focused on speech and language development, leaving a paucity of data on motor and sensory differences. This paper describes preliminary data…

Forbes, Samuel H.; Plunkett, Kim – Developmental Psychology, 2021
Recent years have seen a rise in the popularity of eye-tracking methods to evaluate infant and toddler interpretation of visual stimuli. The application of these methods makes it increasingly important to understand the development of infant sensitivity to the perceptual properties implicated in such methods. In light of recent studies that…

Blau, Shane Reuven – ProQuest LLC, 2023
Infants are born highly sensitive to the natural patterns found in languages. They use their perceptual sensitivity to acquire detailed information about the structure of languages in their environment. To date, most studies of infant perception and early language acquisition have investigated spoken/auditory languages and hearing infants (e.g.…

De Bordes, Pieter F.; Hasselman, Fred; Cox, Ralf F. A. – Journal of Cognition and Development, 2019
From a perceptual learning perspective, infants use social information (like gaze direction) in a similar way as other information in our physical environment (like object movements) to specify action possibilities. In the current study, we assumed that infants are able to learn an affordance upon observing an adult failing to act out that…

Lee, Helen Y.; Vigen, Cheryl; Zwaigenbaum, Lonnie; Smith, Isabel M.; Brian, Jessica; Watson, Linda R.; Crais, Elizabeth R.; Baranek, Grace T. – Autism: The International Journal of Research and Practice, 2021
This study examines the construct validity of the First-Year Inventory 2.0 with respect to other established instruments in a sample of high-risk infant siblings of children with Autism Spectrum Disorder. The First-Year Inventory 2.0 is a parent-report screening instrument designed to identify 12-month-old infants at risk for an eventual diagnosis…

van Loosbroek, Erik; Smitsman, Ad. W. – Developmental Psychology, 1990
Infants were tested at 5, 8, and 13 months of age for numerosity perception. Subjects observed displayed figures on a screen moving at constant speed with irregular trajectories and occasional occlusions. Results demonstrated that discrimination of units, and not of characteristic patterns, underlies numerosity perception. (BC)

Streri, Arlette; Spelke, Elizabeth S. – Cognitive Psychology, 1988
Four experiments studied the perception of the unity and boundaries of objects by 88 4-month-old infants who manipulated them out of the visual field. Infants perceived the unity/boundaries of these objects by detecting the motion patterns they themselves produced. Discrimination between motion patterns transferred from touch to vision. (SLD)

Mattock, Karen; Burnham, Denis – Infancy, 2006
Over half the world's population speaks a tone language, yet infant speech perception research has typically focused on consonants and vowels. Very young infants can discriminate a wide range of native and nonnative consonants and vowels, and then in a process of "perceptual reorganization" over the 1st year, discrimination of most…

Foreman, Nigel; And Others – Journal of Experimental Child Psychology, 1991
Tested infants' latency in turning toward stimulus patterns and the duration of their initial fixation. Results showed that "turning latency" fell in a linear manner from 36 to 120 weeks after conception. Fixation time fell abruptly at 53 weeks. Preterm and full-term infants showed the same developmental trends. (BC)

Alberta Dept. of Education, Edmonton. – 1991
This report puts forth the position of the Ministry of Education of Alberta, Canada, with respect to the physical development of the elementary school student as the basis for his or her cognitive, emotional, social, and moral development. The report describes normal physical development during the first 10 years of life in the domains of…

Ogura, Tamiko – 1987
The development of and relationship between early language, symbolic play, sensorimotor skills, and social development were examined in a longitudinal study conducted in Japan with two young autistic males who were observed from the approximate ages of 2 to 4 years in clinic, day care, and home settings. One child acquired speech; the other did…

Nesdale, Andrew R., Ed.; And Others – 1981
This book consists of 31 papers focusing on aspects of child development. Mainly reports of research, papers are grouped topically into four sections dealing respectively with perceptual, language/communication, cognitive, and social development. Most of the nine papers in section 1 focus on the perceptual development of infants. Topics include…

Slater, Alan, Ed. – 1998
The development of sensory and perceptual ability in infants is an important area of infancy research. This book reflects current knowledge of perceptual development and points to some of the many questions that remain unanswered. The book is divided into four parts. Part 1, "How the Visual System Develops: Normal and Abnormal…

Kalliopuska, Mirja, Ed. – 1995
The third Fenno-Hungarian Conference on Developmental Psychology covered four main concepts: the historical roots and development of social competence through three generations, parent-child interaction, parenthood, and the development of socio-cognitive competence through childhood and adolescence. A series of papers was presented addressing the…
