Presents a mathematical model of the development of reaching behavior in infants, along with the results of two experiments that showed that infant movements could be decomposed into the underlying submovements using a principled method; and the angular error in infant reaches matches the form and magnitude of error assumed by the model. (MDM)

Comments on G. Zivin's model of expressive behavior development, presenting support for (1) affect-induced and (2) spontaneously generated emotion and expressive behavior. Argues that these phenomena are mediated by sensorimotor and sensory-perceptual processes. (HOD)

Thirteen infants were presented with a moving object under two lighting conditions to investigate the role of vision in early reaching. Infants were tested twice, at 5 and 7.5 months of age. The results suggest that proprioceptive feedback and sight of the target allowed for successful reaching with limited visual information, even in relatively…

Five aspects of the psychological assessment of children are considered. First, the hypotheses of assessment are examined, with attention to the role of the scientist-clinician, the nature and the social and personal determinants of development, and the ego as the object assessment. Second, methods of data collection are surveyed, including…

Noting that humans develop according to a genetically encoded timeline and that departure from the timeline limits human potential, this book provides an illustrated practical guide to intervention to help children's bodies work as they should, to nurture children along their developmental timeline, to help children learn "from the inside…

This handbook provides an overview of the development of young children with visual impairments and their educational needs. The first three chapters outline the developmental path followed by sighted children and contrast this with the lives of children who are visually impaired, introduce the professionals who commonly work with children who are…
