01:30States of Arousal During Infancy
States of arousal describe an infant’s physiological and behavioral condition during sleep, wakefulness, and activity. These states are regulated by the circadian rhythm, an internal biological clock that organizes daily patterns of rest and alertness. During infancy, arousal is commonly classified into five states: regular sleep, irregular sleep, drowsiness, alert inactivity, and waking activity.Regular and Irregular SleepDuring regular sleep, an infant’s eyes remain closed, breathing is slow...
01:23Vision During Infancy and Toddlerhood
At birth, vision is the least developed of the major senses because the visual system is still structurally and neurologically immature. The retinas, optic nerves, and visual regions of the brain continue to mature after birth. As a result, newborns have limited visual acuity, or sharpness and clarity of vision, and respond best to objects viewed at close range, roughly 8 to 12 inches away.Rapid Visual DevelopmentVision improves rapidly during the first few months as infants observe and...
01:30Perceptual Development During Infancy
Perceptual development enables infants to organize and interpret sensory information, helping them understand objects, distances, and surfaces in their environment. Two important aspects are depth perception and haptic perception. These abilities develop as infants gain sensory experience and their nervous systems mature.Development of Depth PerceptionDepth perception is the ability to see objects and surfaces in three dimensions and judge their relative distance. Infants gradually learn to use...
01:27Imitation During Infancy and Toddlerhood
Imitation is an important form of learning in early childhood, allowing children to learn new behaviors and participate in social interactions. Children imitate others for different purposes. They may copy adults and peers to learn skills and build social connections. Imitation becomes especially important toward the end of the first year.Early Development of ImitationPiaget observed that infants initially imitate actions they can see themselves perform, such as hand or foot movements. By about...
01:30Sibling Relationships During Infancy and Toddlerhood
Infants often form early attachments to older siblings, using them as a source of comfort during distress. As infants become more mobile, sibling conflict commonly increases over toys, personal space, and parental attention, particularly after about 18 months.Conflict and Social LearningAs toddlers become more involved in family interactions, they learn which behaviors please or annoy their siblings. Although disagreements may involve rivalry or frustration, they can also promote...
