Study Notes
Malnutrition in Infancy
- Marasmus: Severe protein-calorie deficiency, causing wasting of body tissues in infants (<1 year). Results in extreme underweight and muscle atrophy.
- Kwashiorkor: Severe protein deficiency, typically appearing between 1-3 years of age. May cause swollen abdomen and feet, and vital organs prioritize available nutrients, depriving other parts of the body. Symptoms include thin, brittle, colorless hair and listless behavior.
- Cognitive impact: Chronic malnutrition negatively affects cognitive development, specifically attention and memory.
- Positive impact of good nutrition: Proper nutrition improves social development, increasing activity, involvement, helpfulness, reducing anxiety, and increasing happiness.
Dynamic Systems View of Infant Development
- Motor skill development: Infants develop motor skills (e.g., rolling, sitting, standing) in a specific order and time frame.
- Dynamic systems theory: Infant motor skills are solutions to achieve goals, emerging as the nervous system, physical capabilities, child's goals, and environmental support converge.
- Active role of the infant: Infants perceive environmental stimuli, which motivates action and fine-tuning of movements.
- Maturation and Development: Motor development is not merely the unfolding of a genetic plan, but a complex interaction of various factors.
