    curl toes under when an object is pressed under them
  9. Describe the rooting reflex

    8 weeks when the baby begins to sleep at night
  13. by ____ months the babies are sleeping for 14 hours a day
    6 months
  14. 3 types of normal crying
    • Basic cry: rhythmic and signals for hunger

    • Pain Cry: very abrupt onset
  15. Abnormal crying in some babies; an intense bout of crying for no apparent reason
    colic crying
  16. The process of cartilage hardening into bones
    ossification
  17. What type of development is responsible for the improvements in co-ordinational movements?
    changes in the number and density of bones
  18. 2 pathways that ossification proceeds

    high ration of water
  20. describe the changes in fat content to the age of 1
    fat levels decline to near levels of an adult by the age of 1
  21. Describe the growth process of the heart and the lungs in infants
    • grow quickly
    • become more efficient by the age of 2
  22. 3 groups of motor skills achieved in infancy
    • Locomotor skills: crawling 
    • Nonlocomotor skills: head movements
    • Fine motor skills: use of the hands
  23. Describe the visual acuity of a baby less than a year old
    • poor visual acuity. 
    • Baby can see at 20m what adults can see at 400m
  24. Describe the development of colour vision at one month of age
    all 3 visual cones are present at one month of age
  25. Describe the auditory acuity  for a newborn

    prompt attention to crying in the first thee months leads to less crying later on

    • Operant conditioning
  32. Describe the critical period related to development of sight
    • early visual stimulation
    • a specific quality of visual stimulation is needed to develop normal visual perception
  33. How would a nativist  explain perceptual development?
    theorists who claim perceptual abilities are inborn
  34. How would a empiricist explain perceptual development?
    argue perceptual abilities are learned
