Study Notes
Malnutrition in Infants
- Marasmus: Severe protein-calorie deficiency, causing wasting of body tissues in infants under one year old. Infants become significantly underweight, and muscle mass atrophies (decreases).
- Kwashiorkor: Severe protein deficiency, typically occurring between the age of 1 and 3. Can cause abdominal and foot swelling (edema). Vital organs prioritize nutrient uptake, starving other areas of the body. Hair becomes thin, brittle, and colorless, and behavior may be listless.
- Long-term effects of malnutrition: Chronic malnutrition negatively impacts cognitive development (attention and memory). Improved nutrition and feeding can enhance social development, making children more active, involved, helpful with peers, less anxious, and happier.
Dynamic Systems View of Motor Development
- Motor skill development: Infants develop motor skills in a specific sequence (rolling, sitting, standing).
- Dynamic systems theory: Infants combine motor skills to perceive and act in the environment. Infants' perceptions guide refinement of movements to achieve goals.
- Factors influencing motor skills: Nervous system development, body's physical properties and movement potential, child's goals, and environmental support.
- Motor skills as solutions: Motor skills are developed as solutions to achieve infant goals, based on their motivation to act in the environment, and their perception in guiding adjustments.

Description
This quiz explores the impact of malnutrition in infants, focusing on conditions such as Marasmus and Kwashiorkor. It also examines the dynamic systems view of motor skill development, detailing how infants progress through different milestones. Understanding these concepts is crucial for enhancing infant health and development.
