16. 16 Vision and Visual Perception Infants are born with a full intact set of visual structures. Newborns’ eyes are sensitive to brightness They have some control over eye movement Newborns focus optimally on objects at a range of 7 to 10 inches They look primarily at the edges and contours of objects Are responsive to human face and are able to imitate facial expressions By the first 4 to 6 months, infants can focus almost as well as adults, acuity sharpens, and they can discriminate between most colors

17. 17 Depth and Distance Perception Because the newborn eyes are not well coordinated and the infant has not yet learned to interpret all of the information transmitted by the eyes. Early depth perception is probably not very sophisticated. Even when coaxed by their mothers, infants 6 months or over will not crawl over the edge of the visual cliff.

18. 18 Auditory Perception Neonates can hear. They are startled by loud sounds Newborns are soothed by low-pitched sounds such as lullabies Infants seem able to localize sounds, and prefer human voices

20. Three Types of Children 1. The Easy Child - this child showed regular eating, sleeping, elimination cycles, a positive approach response to new situations, and could accept frustration with little fuss. They adapted to change, such as new food or a new school quickly.

21. Three Types of Children 2. The Difficult Child : – this child showed irregular eating, sleeping, and elimination cycles. They displayed a negative approach response to new situations, for example frequent and loud crying. – They are slow to adapt to change, and need more time to get used to new food or people. Most of the problems reported with these children canters around socialization patterns, expectations of family, school, and peer groups.

22. Three Types of Children 3. The Slow-to-Warm-Up Child - this child showed negative responses of mild intensity when exposed to new situations, but slowly came to accept them with repeated exposure.

24. Cognitive Development Cognitive development refers to the ways children reason (think), develop language, solve problems, and gain knowledge. Identifying colors, completing a maze, knowing the difference between one and many, and knowing how things are similar are all examples of cognitive tasks
