Infant Perception of Audio-Visual Speech Synchrony
Peer reviewed Peer reviewed
Direct linkDirect link
Lewkowicz, David J. – Developmental Psychology, 2010
Three experiments investigated perception of audio-visual (A-V) speech synchrony in 4- to 10-month-old infants. Experiments 1 and 2 used a convergent-operations approach by habituating infants to an audiovisually synchronous syllable (Experiment 1) and then testing for detection of increasing degrees of A-V asynchrony (366, 500, and 666 ms) or by…

Perceiving Bimodally Specified Events in Infancy.
Peer reviewed Peer reviewed
Spelke, Elizabeth S. – Developmental Psychology, 1979
Three experiments investigated four-month-old infants' capacity to perceive bimodally specified events by detecting the temporal synchrony of sound bursts with the visable impacts of surfaces. (Author/SS)

The Relation Between Audition and Vision in the Human Newborn
Peer reviewed Peer reviewed
Mendelson, Morton J.; Haith, Marshall M. – Monographs of the Society for Research in Child Development, 1976
Four studies were conducted to investigate the relation between audition and vision in the human newborn. In all four studies visual activity was recorded with infrared corneal-reflection techniques in 1- to 4-day-old infants. (MS)

Mendelson, Morton J.; Haith, Marshall M. – 1976
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…

Discrimination of Male Voice Quality by 8 and 9 Week Old Infants.
Culp, Rex E.; Gallas, Howard B. – 1975
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…

Young Children's Responses to Discrepant Social Communications.
Volkmar, Fred R.; Siegel, Alberta E. – 1976
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…

An Integrated Evaluation Approach for the Handicapped Child 0 to Three Years.
Richman, Jack E.; And Others – 1983
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…
