| JEAN PIAGET -- COGNITIVE DEVELOPMENTAL THEORY Sensorimotor stage -- ages birth to 2 years Infants "think" by acting on the world with their eyes, ears, and hands. As a result, they invent ways of solving sensorimotor problems, such as pulling a lever to hear the sound of a music box, finding hidden toys, and putting objects in and taking them out of a container. Preoperational stage -- ages 2 to 7 years Preschool children use symbols to represent their earlier sensorimotor discoveries. Development of language and make-believe play takes place. However, thinking lacks the logical qualities of the two remaining stages. Concrete Operational stage -- ages 7 to 11 years Children's reasoning becomes logical. School age children understand that a certain amount of lemonade or play dough remains the same even after its appearance changes (object permanence). They also organize objects into hierarchies of classes and subclasses. However, thinking falls short of adult intelligence. It is not yet abstract. Formal Operational stage -- 11 years and upward The capacity for abstraction permits adolescents to reason with symbols that do not refer to objects in the real world, as in advanced mathematics. They can also think of all the possible outcomes in a scientific problem, not just the obvious ones. |
| SIGMUND FREUD -- PSYCHOSEXUAL THEORY Oral Stage -- ages birth to 1 year The new ego directs the baby's sucking activities toward breast or bottle. If oral needs are not met appropriately, the individual may develop such habits as thumb sucking, fingernail biting, and pencil chewing in childhood; overeating and smoking in adulthood. Anal Stage -- ages 1 to 3 years Young toddlers and preschoolers enjoy holding and releasing urine and feces. Toilet training becomes a major issue between parent and child. If parents insist that children be trained before they are not ready or make too few demands, conflicts about anal control may appear in the form of extreme orderliness and cleanliness or disorder and messiness. Phallic Stage -- 3 to 6 years Id impulses transfer to the genitals, and the child finds pleasure in genital stimulation. Freud's Oedipus Conflict for boys and Electra conflict for girls take place. Young children feel a sexual desire for the opposite-sex parent. To avoid punishment, they give up this desire, and instead, adopt the same-sex parent's characteristics and values. As a result, the superego is formed. The relations between the id, ego, and superego established at this time determine the individual's basic personality orientation. Latency Stage -- 6 to 11 years Sexual instincts die down, and the superego develops further. The child acquires new social values from adults outside the family and from play with same-sex peers. Genital Stage -- adolescence Puberty causes the sexual impulses of the Phallic Stage to reappear. If development has been successful during earlier stages, it leads to marriage, sexual maturity, and the birth and rearing of children. |

| ERIK ERIKSON -- PSYCHOSOCIAL THEORY Trust vs. Mistrust -- birth to one year Babies learn either to trust OR mistrust that others will care for their basic needs, including nourishment, sucking, warmth, cleanliness, and physical contact. This stage corresponds with Freud's Oral Stage. Autonomy vs. Shame and Doubt -- 1 to 3 years Children learn either to be self-sufficient in many activities, including toileting, feeding, walking, talking, OR to doubt their own abilities. This stage corresponds with Freud's Anal Stage. Initiative vs. Guilt -- 3 to 6 years Children want to undertake many adult-like activities, sometimes overstepping the limits set by parents and feeling guilt. This stage corresponds with Freud's Phallic Stage. Industry vs. Inferiority 7 to 11 years Children busily learn to be competent and productive or feel inferior and unable to do anything well. This stage corresponds with Freud's Latency stage. Identity vs. Role Confusion -- adolescence Adolescents try to figure out, "Who am I?" They establishe sexual, ethnic, and career identities, OR are confused about which future roles to play. This stage corresponds with Freud's Genital stage. Intimacy vs. Isolation Young adults seek companionship and love with another person OR become isolated from others. Generativity vs. Stagnation -- adulthood Middle-aged adults are productive, performing meaningful work and raising a family, OR become stagnant and inactive. Integrity vs. Despair -- maturity Older adults try to make sense out of their lives, either seeing life as a meaningful whole, OR despairing at goals never reached and questions never answered. |

| URIE BRONFENBRENNER -- ECOLOGICAL SYSTEMS THEORY OF HUMAN DEVELOPMENT The Microsystem -- The immediate setting that contains the child. Includes physical space and activities therein, most important people to the particular child, and interactions between the child and the important people. The Mesosystem -- Made up of the relationships among the different settings in which the child spends time during different periods of development. Interrelations among microsystems. The Exosystem -- A set of specific social structures that do not directly contain the child but still have impact on the child's development. These structures influence, delimit, or even determine what goes on in the child's microsystem. The Macrosystem -- Consists of all the elements contained in the child's micro-, meso-, and exosystems, plus the general underlying philosophy or cultural orientation within which the child lives. This is the overarching institutional patterns of the culture or subculture, such as the economic, social, educational, legal, and political systems of which the local micro-, meso-, and exosystems are the concrete manifestations. The Chronosystem -- (outside the Macrosystem) Temporal changes in children's environments, which produce new conditions that affect development. These changes can be imposed externally or arise from within the child. (time) |
