“…Recent studies on haptic touch evidenced that before their fifth day of life, full-term newborns can discriminate object textures (Molina & Jouen, 2003), weights (Hernandez-Reif, Field, Diego, & Largie, 2001), or shapes (Streri, Lhote, & Dutilleul, 2000). Premature newborns, at least at 28 weeks PC, can also discriminate different objects by their shape (Marcus, Lejeune, Berne-Audéoud, Gentaz, & Debillon, 2012).…”

Historically, newborns, and especially premature newborns, were thought to "feel nothing." However, over the past decades, a growing body of evidence has shown that newborns are aware of their environment, but the extent and the onset of some sensory capacities remain largely unknown. The goal of this review is to update our current knowledge concerning newborns' perceptual world and how ready they are to cope with an entirely different sensory environment following birth. We aim to establish not only how and when each sensory ability arises during the pre-/postbirth period but also discuss how senses are studied. We conclude that although many studies converge to show that newborns are clearly sentient beings, much is still unknown. Further, we identify a series of internal and external factors that could explain discrepancies between studies, and we propose perspectives for future studies. Finally, through examples from animal studies, we illustrate the importance of this detailed knowledge to pursue the enhancement of newborns' daily living conditions. Indeed, this is a prerequisite for assessing the effects of the physical environment and routine procedures on newborns' welfare.

“…Infants begin to move and interact with their environment prior to birth, setting the stage for a lifetime of interaction between the sensory and motor systems. While early fetal movement appears to be spontaneously generated, both rat and human research suggests that movement in the prenatal period can be modified using sensory input . At birth, infants are exposed to a whole new world of sensory input and motor demands.…”

Infants develop skills through a coupling between their sensory and motor systems. Newborn infants must interpret sensory information and use it to modify movements and organize the postural control system based on the task demands. This paper starts with a brief review of evidence on the use of sensory information in the first months of life, and describes the importance of movement variability and postural control in infancy. This introduction is followed by a review of the evidence for the interactions between the sensory, motor, and postural control systems in typically development infants. The paper highlights the ability of young infants to use sensory information to modify motor behaviors and learn from their experiences. Last, the paper highlights evidence of atypical use of sensory, motor, and postural control in the first months of life in infants who were born preterm, with neonatal brain injury or later diagnosed with cerebral palsy (CP).Infants begin to move and interact with their environment prior to birth, setting the stage for a lifetime of interaction between the sensory and motor systems. While early fetal movement appears to be spontaneously generated, both rat and human research suggests that movement in the prenatal period can be modified using sensory input.

“…These infants failed to display any effective discrimination between the smooth and angular objects, unlike the infants in the silence group. Previous studies have shown that preterm infants do have the ability to memorise tactile information about the specific features of an object and to detect differences with another object . Our study revealed that the presence of a voice had a negative impact on their sensory learning.…”
