Lejeune, Fleur; Marcus, Leila; Berne-Audeoud, Frederique; Streri, Arlette; Debillon, Thierry; Gentaz, Edouard – Child Development, 2012
This study investigated the ability of preterm infants to learn an object shape with one hand and discriminate a new shape in the opposite hand (without visual control). Twenty-four preterm infants between 33 and 34 + 6 gestational weeks received a tactile habituation task with either their right or left hand followed by a tactile discrimination…

Human Fetal Heart Rate Dishabituation between Thirty and Thirty-Two Weeks Gestation.
Peer reviewed Peer reviewed
Sandman, Curt A.; Wadhwa, Pathik; Hetrick, William; Porto, Manuel; Peeke, Harmon V. S. – Child Development, 1997
Examined the ability of 32-week human fetuses to learn and recall information. Found a significant heart rate habituation pattern for a series of vibroacoustic stimuli. After a single novel stimulus, the heart rate to stimulus 1 reemerged. Uterine contractions were not related to presentation of the novel stimulus or change in heart rate after the…

Physiological Self-Regulation and Information Processing in Infancy: Cardiac Vagal Tone and Habituation.
Peer reviewed Peer reviewed
Bornstein, Marc H.; Suess, Patricia E. – Child Development, 2000
Investigated the role of physiological self-regulation (cardiac vagal tone) in information processing (habituation) in infants. Found that decreases in vagal tone consistently related to habituation efficiency at 2 and 5 months. Within- and between- age suppression of vagal tone predicted accumulated looking time (ALT), but ALT did not predict…

Infants' Perception of the Audible, Visible, and Bimodal Attributes of Multimodal Syllables.
Peer reviewed Peer reviewed
Lewkowicz, David J. – Child Development, 2000
Three experiments investigated 4-, 6-, and 8-month-olds' perception of the audible, visible, and combined attributes of bimodally specified syllables. Results suggested that at 4 months, infants attended primarily to the featural information, at 6 months primarily to the asynchrony, and at 8 months to both features independently. (Author/KB)
