Prevalence of self-injurious behavior (SIB) is as high as 50% among children with autism spectrum disorder (ASD). Identification of risk factors for the development of SIB is critical to early intervention and prevention. However, there is little empirical research utilizing a prospective design to identify early risk factors for SIB. The purpose…

Four developmentally delayed babies were given semicircular canal stimulation in an effort to facilitate their motor and reflex development. All of the children showed motor and/or reflex changes that were attributable to the vestibular stimulation. In addition, some evidence was obtained linking changes in stereotypic responding to the vestibular…

Longitudinal studies of mother-child interactions for the third trimester of pregnancy to age 4 are described.

Studied were the behavioral characteristics of 60 methadone addicted infants and 53 nonaddicted infants during the first year of life (neonatal period, and at 3, 6, and 12 months of age). (PT)

An interaction analysis observation instrument, with categories found in the definition of "executive competence" by Wenar and related to R. White's effectance motivation, was used to observe 37 toddlers with their mothers. (SB)

Provides data indicating that development occurs in cycles, with behavioral competencies appearing and developing and then disappearing only to reappear again in a more complex form at a later age. Data on conservation and auditory-manual coordination in infancy are used to support this theory. (ED)

Explores the relation between the infant's ability to negotiate the environment and the quality of the infant-mother attachment relationship. (HOD)

This paper presents some findings of a detailed analysis of infants' approach behavior in a familiar, naturalistic setting.

Instances of infant approach to both mother and observer were coded from the…

The original "Bayley Scales of Infant Development" (BSID) (Bayley 1969) have been among the most popular measures of performance and aptitude of infants.
