  1. Cognitive Development across the Lifespan of Human Development By: Shadra Tomei Sparling CEPD 8102 Dr. Hayes

  2. Jean Piaget • Born in 1896, died in 1980. • He was an epistemologist who studied children’s intellectual development. • Developed a theory of cognitive development. “He posited that children progress through 4 stages and that they all do so in the same order” (Learning Theories Knowledgebase, 2010). It consists of four stages of intellectual development: Sensorimotor stage, Preoperational stage, Concrete Operational stage, and the Formal Operational stage.

  3. Intelligence changes throughout our lifespan…here are the stages and the theories: Infancy: Sensory and Perceptual Development, Sensorimotor stage. Early Childhood: Preoperational stage. Middle/Late Childhood: Concrete Operational stage. Adolescence: Formal Operational stage. Early Adulthood: Postformal Thought. Middle Adulthood: Crystallized and Fluid intelligence. Late Adulthood: Sensory/Motor and Speed-of-Processing dimensions of cognition.

  4. Maturation “The term maturation refers to a uniform progression of changes in brain organization and function in infants growing in any reasonably natural environment” (Kagan, 2008).

  5. Processes of Development • Schemes: actions or representations that organize knowledge. • Assimilation: use of existing schemes to deal with new information. • Accommodation: adjustment of schemes to take in new information. • Organization: groupings of behaviors and thoughts into a higher-order system. • Equilibration: moving from one stage of cognitive development to the next.

  6. Cognitive Development in Infancy (Birth to age two) • Sensorimotor Stage. • Object Permanence: Is an object there? • Sensory Input: Touching a toy. • Motoric Action: protruding the tongue.

  7. Cognitive Development in Early Childhood (Ages 2-7) • Preoperational Stage. • Egocentrism: Is that you or me? • Intuitive Thought Substage: Let’s play 20 questions. • Centration: Piaget’s Conservation Task.

  8. Cognitive Development in Middle/Late Childhood (Ages 7-11) Concrete Operational Stage. Classification: putting things into groups. Seriation: ordering stimuli by dimension. Transitivity: Logically combine relations to understand conclusions.

  9. Cognitive Development in Adolescence (Ages10-22) • Formal Operational Stage. • Abstract Thinking: Thinking about thought itself. • Logical Thinking: Does this make sense? • Idealistic Thinking: The world is perfect. • Hypothetical-deductive reasoning: creating a hypotheis, and deducing implications (testing it).

  10. Cognitive Development in Early Adulthood (Ages 18-25) • Postformal thought. • Pragmatic thinking: Applying knowledge in their work. • Reflective/Relativistic thinking: Being able to view other perspectives and opinions(mutual respect). • Creativity: What can I invent?

  11. Cognitive Development in Middle Adulthood (Ages 40-65) • Fluid Intelligence: Abstract reasoning declines. • Crystalized Intelligence: a person’s accumulated information and verbal skills increases.

  12. Cognitive Development in Late Adulthood (Ages 60-death) • Sensory/Motor: Declines with age. • Speed-of-Processing: Declines due to a decline in brain functioning. • Attention: Selected, Divided, or Sustained. • Memory: Health, education, and socioeconomic status affect this. • Wisdom: Expert knowledge about practical aspects of life.
