This study investigated the possibility of a functional relation between the auditory and visual systems in the human newborn beyond reflexive organization. Visual activity was monitored in 16 newborns through the use of infrared corneal reflection video tape recording. Infants were observed in total darkness and while monocularly viewing a…

This paper reports a study which investigated 2-month-old infants' auditory discrimination of tone quality in the male voice, extending a previous study which found that voice quality changes (soft versus harsh) in a female voice were discriminable by infants at this age. Subjects were 20 infants, tested at 8 and 9 weeks of age. Each infant was…

This study attempted to assess how very young children respond to discrepant social communications. Forty children, ages 12 to 42 months, with their mothers were exposed to four trial situations: two discrepant, two nondiscrepant communication episodes. Two observers recorded each child's movement and behavior. Results indicated a significant…

This experimental study has three aims: (1) to give a detailed description of imitative behavior as it develops during the first six months of life; (2) to compare imitative responses perceived through visual, kinesthetic and auditory modalities; and (3) to describe and explain the regulating mechanisms and processes present in the early…

This study examined individual patterns of the maturation of auditory evoked potential (AEP) in normal infants to determine whether longitudinal data show less variability than cross-sectional data, and to further assess the effect of stage of sleep on AEP. The AEPs for 10 children were examined by repeated testing between the ages of about two…

While the commitment to technology for neonatal and infant hearing screening in this country has come a long way and is evolving rapidly, the average age of 18-30 months, at which young children with auditory disabilities are identified, is still unacceptable. The promise of earlier detection, diagnosis, and habilitation of hearing loss is within…

Techniques to assess the vision, hearing, and speech and language of multihandicapped children are briefly described. Interferences in normal vision functioning and development during infancy can be identified and intervention initiated early in the child's life. Obtaining an in-depth history from the parents is the first step. It is essential…
