Modified prenatal sensory stimulation influences postnatal behavioral and perceptual responsiveness in bobwhite quail chicks (Colinus virginianus).

Intersensory Experience and Early Perceptual Development: Attenuated Prenatal Sensory Stimulation Affects Postnatal Auditory and Visual Responsiveness in Bobwhite Quail Chicks {Colinus virginianus)

Related experiments examined the effects of attenuated prenatal sensory stimulation on subsequent postnatal auditory and visual responsiveness in precocial bobwhite quail chicks {Colinus virginianus). Results revealed that denying quail embryos the prenatal vestibular and tactile stimulation provided by broodmates during incubation alters preand postnatal perceptual functioning. Chicks incubate...

Effects of Prenatal Sensory-Evoked Arousal on Postnatal Behavior and Perceptual Responsiveness in Bobwhite Quail (Colinus virginianus) by

Prenatally elevated physiological arousal interferes with perceptual learning in bobwhite quail (Colinus virginianus) embryos.

Neonatal studies suggest elevated arousal can negatively influence perceptual and cognitive processes during early development. The authors explored this issue during the prenatal period by pharmacologically elevating physiological arousal in bobwhite quail (Colinus virginianus) embryos during exposure to a maternal call, then assessing preference for the familiar call following hatching. Embry...

Intersensory redundancy facilitates prenatal perceptual learning in bobwhite quail (Colinus virginianus) embryos.

Information presented redundantly and in temporal synchrony across sensory modalities (intersensory redundancy) selectively recruits attention and facilitates perceptual learning in human infants. This comparative study examined whether intersensory redundancy also facilitates perceptual learning prenatally. The authors assessed quail (Colinus virginianus) embryos' ability to learn a maternal c...

Biased embryos: Prenatal experience alters the postnatal malleability of auditory preferences in bobwhite quail.

Many precocial birds show a robust preference for the maternal call of their own species before and after hatching. This differential responsiveness to species-specific auditory stimuli by embryos and neonates has been the subject of study for more than four decades, but much remains unknown about the dynamics of this ability.
