Reviews examples from the recent psychological literature relating to object orientation and constancy.

A theoretically more acceptable…

Presents a day care curriculum for infants and toddlers which is designed to provide maximum learning experiences and is based on Piaget's and Erickson's theories of infant development. (Author/ED)

Cardiac response to stimulation of the left and right perioral region in infants was examined. Cardiac acceleration and ipsilateral head turning occurred more reliably to stimulation of the infant's right side than to stimulation of the left side. Results reflect a difference in sensitivity at the infant's two sides. (SDH)

A study suggesting semantic rather than syntactic early language acquisition by children. (CH)

This paper describes three experiments which demonstrated the presence of binaural perception abilities (the ability to use both ears) in 4-month-old but not in 2-month-old infants. All of the experiments employed a visual fixation habituation-dishabituation paradigm in which infants were given a series of visual fixation trials while binaural…

The relationship of bilirubin (a red bile pigment that is sometimes found in the urine and occurs in the blood and tissues in jaundice) in infancy to later intellectual development was investigated in 241 infants with moderately elevated and high bilirubin levels. Ss were administered motor, psycholinguistic, and intelligence tests at age 8…

This study formulated a multivariate model of early infant competence from variables representing a transactional perspective of developing competence in early infancy. The measures used in the competence model were: birth weight; habituation index; personality ratings of the infants' social orientation and task orientation; ratings of maternal…

Evaluated were the learning abilities and general adjustment of 50 5- to 14-year-old children who had pyloric stenosis (an easily correctable condition of starvation) in infancy. (CL)

Discussed are principles for parents to remember when teaching their young handicapped children new skills. (CL)

Evaluated was retinal functioning of 15 4-year-old children who had received phototherapy for neonatal hyperbilirubinemia (jaundice). (DB)

Presented is the case history of a newborn infant in which death from jaundice was probably connected with maternal ingestion of fava beans and large dosages of Vitamin C. (DB)

Evaluation of 222 infants with imperforate anus found an incidence of cardiovascular malformations 20 times greater than would be expected. (DB)
