According to Jean Piaget, there are four major stages of cognitive development:
1. Sensorimotor Stage. This stage occurs between the ages of birth and two years of age.
Sensorimotor (infancy): During this stage, which includes six distinct substages, intelligence is demonstrated through motor activity with limited use of symbols, including language; the infant’s knowledge of the world is primarily based on physical interactions and experiences.
2. Preoperational Stage. The second stage occurs between the ages of 2 - 7 years. During this stage, intelligence is increasingly demonstrated through the use of symbols; memory and imagination are developed as language use matures; thinking is nonlogical, nonreversible, and egocentric.
3. Concrete Operations Stage. Occurring between ages 7 and about 12 years. During this stage—characterized by conservation of number, length, liquid,mass, weight, area, volume—intelligence is increasingly demonstrated through logical and systematic manipulation of symbols relating to concrete objects; thinking is operational, reversible, and less egocentric.

4. Formal Operations Stage. The final stage of cognitive development (from age 12 and beyond). During this final stage, intelligence is demonstrated through the logical use of symbols related to abstract concepts; thinking is abstract, hypothetical, and early on, quite egocentric; it is commonly held that the majority of people never complete this stage.

Did you see that: the majority of people never complete the final stage of cognitive development? Is this true?
My two cents: judging from the fact that I forgot the take the unpopped kernels out before making popcorn trail mix where I added nuts, thereby confusing Moira who now thinks she 'can't eat the seeds', I'd say I'm not exactly demonstrating formal operations intelligence.

I'm so impressed that you are constantly reading and growing like this! Please say that you do light reading too, because I'm feeling pretty loserish right now thinking about the things I've read this summer... :)
I majored in Human Development in college and the theories class absolutely fascinated me. As for formal operations stage, just thinking about the way I go through my daily life, I'm doubtful that my thinking and problem solving strategies are "advanced" so I guess I'm one of the many who have not completed this stage!
Hello, it says twelve and up! I'd say we all have plenty of time to work on our "advanced" thinking and problem solving strategies.
By the way, Reba, perhaps you are way ahead of all of us - seems like leaving the popcorn seeds in the trail mix is abstract, hypothetical thinking - after all I'm sure one day we will find out how important it is to eat (OK, perhaps swallow whole) popcorn kernels!
