Left-‐side weakness or paralysis Ch. 5 Developmental Psychology • Developmental Psychology is concerned with the study of physical, mental, and social changes that occur throughout the cycle of life. • Most research has centered on the development of children • Three major focuses: 1. What factors affect a child’s emotional development? 2. What factors affect a child’s cognitive or intellectual development? 3. What factors affect a child’s social development? 1. Emotional Development • Look at research today demonstrating how touch and cuddling affect the emotional development of children. • Series of very early studies conducted by Dr. Harry Harlow of the University of Wisconsin (using Rhesus monkeys) • Harlow’s studies show that our social environment is very critical to our eventual ability to attach to others later in life • In other words, touch deprivation can be extremely harmful! • The idea is that we need caring adults to develop emotional stability • It builds our sense of security and independence • So, good parenting is far more than feeding, changing, and protection • It must include touching, cuddling, and caressing! o Note: these behaviors are very natural tendencies for adults • Importantly, Harlow’s early research has led directly to the recent practice of holding babies in hospital ICU’s • In hospitals today, babies are cuddled 20-‐30 minutes every 6 hours. • Child psychologist Tiffany Field has shown that: o Premature infants massaged 15 minutes three times a day gained weight 47% faster than preemies not touched • In addition, massaged infants were: o More alert and interactive when awake o Slept deeper and longer when asleep 2. Cognitive or Intellectual Development • Jean Piaget’s Stages of Cognitive Development o Proposed that cognitive development in children occurs through a series of stages o Stages: § Sensorimotor • experiencing the world through senses and actions • Milestone: object permanence, stranger anxiety § Preoperational • representing things with words and images but lacking logical reasoning • Milestone: pretend play, egocentrism, language development § Concrete Operational • Thinking logically about concrete events; grasping concrete analogies and performing arithmetical operations • Milestone: conversation, mathematical transformations § Formal Operational • Abstract logic o At about age 2 (in the Sensorimotor Stage), children learn that when an object is covered, it still remains in existence § Called: Object Permanence § Before that, when an object is covered, it doesn’t exist to the child…IT GOES AWAY! § This is why peek-‐a-‐boo is so much fun for kids under 2 § During the concrete operational stage: • Principle of conversation is when kids are more likely to pick the taller object because it seems like there is more to them (even if it is equal) • Ask child “Which glass has more water in it, container A or C?” (C is taller) • Before learning principle? o Child will always pick container C • After learning principle? o Child will say neither
