Study Notes
Growth and Development Through Lifespan
- Development is analogized to a tree with branches representing various skills across major domains: physical, cognitive, emotional, and social.
- Each developmental domain is interrelated, indicating an interconnected growth process.
Stages of Early Childhood Development
- Newborn (0-3 m)
- Infant (4-6 m, 7-9 m, 10-12 m)
- Toddler (13-18 m, 18-24 m)
- Pre-school (2-4 y)
- School-age (4-6 y)
Perceptual Development
- Includes the development of sensory modalities: hearing, vision, touch, taste, and smell.
- Newborns have all five senses but require tuning for optimal function.
Hearing Development
- Newborns startle at loud sounds and can head-turn in response to voices by 2 months.
- They prefer human speech and can distinguish sounds relevant to language, primarily low-frequency until 3 months.
- Absorb sounds within 500-1,000 Hz effectively for speech perception.
Vision Development
- Newborns focus at close range (8-12 inches), with limited depth perception.
- Can perceive contrast colors (black, white, red, green) but not full range until 4 months.
- Show tracking abilities for moving toys and facial recognition while lying on their back.
Touch Development
- Most developed sense at birth; newborns respond to touch with reflexes.
- Seek physical contact which is calming, responding positively to rocking and gentle sounds.
Taste Development
- Taste buds form early; infants prefer sweet flavors, showing a strong liking for breast milk.
Smell Development
- The olfactory center develops early; newborns prefer the scent of their mother.
Cognitive Development
- Explains cognitive growth through Piaget’s theory and Information-processing theory.
- Cognitive milestones include cooing, smiling, interest in faces, and distinct crying patterns for different needs.
Language Development
- At 2 months, newborns coo; by 4 months, they begin babbling; at 6 months, joint attention with caregivers develops.
- Babbling includes more refined sounds (notably "m" and "b").
Social Development
- Encompasses interactions with others, crucial for emotional and social skill-building.
