Piaget's Stages of Cognitive Development

StageAgeCharacteristics of Stage
Sensorimotor0-2The child learns by doing: looking, touching, sucking. The child also has a primitive understanding of cause-and-effect relationships. Object permanence appears around 9 months.
Preoperational2-7The child uses language and symbols, including letters and numbers. Egocentrism is also evident. Conservation marks the end of the preoperational stage and the beginning of concrete operations.
Concrete Operations7-11The child demonstrates conservation, reversibility, serial ordering, and a mature understanding of cause-and-effect relationships. Thinking at this stage is still concrete.
Formal Operations12+The individual demonstrates abstract thinking, including logic, deductive reasoning, comparison, and classification.

3 Types of learning - classical learning (Pavlovian), occurs by association when a stimulus that evokes a certain response becomes associated with a different stimulus that originally did not cause that response; operant conditioning (Skinnerian), learning occur through application of rewards, punishments; observational learning, achieved by observing and imitating others.

Robert Sternberg's triarchic theory, intelligence three aspects: componential (critical aspect, ability to use internal inform-processing startegies when identif and thinking bout solve problem, incl eval results), experiential intelligence (insightful, ability to transfer learning effectively to new skills), contextual intelligence (practical, ability to transfer learning to new skills... import part of is tacit knowledge or savvy is ability to work system to one's advantage, often thought as "street-smart").
    Moral development and judgement, Lawrence Kohlberg moral developm with three levels consisting of six stages... first level - preconventional morality, has to do with moral reasoning and behavior based on rules and fear of punishment (Stage 1) and nonempathetic self-interest (s 2), second l conventional morality, conformity & helping others (3) obeying law keeping order (4), postconventional (3rd l) accepting relative changable natur of rules laws (stage 5) and conscience-directed concern with human rights (6).
