Document Summary

Systematic research on adolescent cognitive development began with testing piaget"s ideas. Formal operational stage: age 11; develop capacity for abstract, systematic, scientific thinking. No longer require concrete things/events as objects of thoughts. Come up with new, more general logical rules through internal reflections. Operational children can operate on reality , formal operational can operate on operations . Begins with possibility & proceeds into reality. Concrete operational children start with reality w/ obvious prediction with no alternative, fail to solve problem if not confirmed. Performance illustrates on piaget"s famous pendulum problem approach. Example: present school-age children & adol w/ diff length string, diff weight objects to attach, & bar to hang strings; then ask what influences the speed with which pendulum swings through its arc. Formal operational: hypothesize 4 variables might be influential: string length, weight of object hung on it, how high the object is raised before it"s released, how forcefully object is pushed.
