Document Summary

Examines physical, cognitive and social development across the life span: most impressionable when you are young. Extreme view: psychological development occurs in a series of abrupt, age-linked stages: analogy: caterpillar to butterfly, like physical development: crawling to walking. Serial: development tends to happen in order: e. g. reading can"t happen until letter sound correspondence is understood. Stages build up based on the previous stage (kids crawl first and then walk) Age linking- flexible and experience-dependent: e. g. reading age depends on when taught letter sound correspondence. Abrupt : old mistakes might still happen, but with much less frequency. Mistakes tell us where they are developmentally (knowledge and skills) Schemas or belief systems, are necessary to make sense of our experiences. Assimilation: interpreting new experiences using existing schemas. Schemas accommodate new information provided by experiences (schemas modify themselves to become more complex, subtle or greater in number) Sensorimotor: birth to nearly 2 years, experience world through sensing and acting, development of memory.
