To benefit from the exploration of their bodies and their physical and social environments, infants need to detect sensorimotor contingencies linking their actions to sensory feedback. This ability, which seems to be present in babies from birth and even in utero, has been widely used by researchers in their study of early development. However, a…

Over the first weeks and months following birth, infants' initial, broad-based perceptual sensitivities become honed to the characteristics of their native language. In this article, we review this process of emerging specialization within the context of a cascading "critical period" (CP) framework, in which periods of maximal openness…

Alyssa Conklin-Moore discusses normalization in the child under three from several perspectives. She takes an extensive look at the child, including orienting parents to the Montessori environment, the child's entrance into the environment, addressing the sensitive periods, and fostering independence, contribution, and community. She reminds the…

Background: Traumatic brain injury (TBI) in infancy is relatively common, and is likely to lead to poorer outcomes than injuries sustained later in childhood. While the headlines have been grabbed by infant TBI caused by abuse, often known as shaken baby syndrome, the evidence base for how to support children following TBI in infancy is thin.…

A description of the development of movement by infants covers prenatal influences, gravity influences, sensory aspects of motor skills, deformities and deviations in the developmental sequence, and ways to assist infants with abnormal development patterns. (CB)

The final report provides a detailed description of the development of the Peabody Mobility Kit for Infants, which provides programmed instruction in orientation and mobility for multiply impaired blind infants. It describes the development of the criterion referenced assessment scales and instructional activities, the empirical validation of the…

Intended to assist teachers as they assess, plan for, and teach deaf blind students, this manual describes a process for adapting curricula for students who function within the 0-24 month developmental period, also known as the sensorimotor period. The manual's first section provides an overview of project activities including the literature…
