piaget's stages of cognitive development

bc teach said is on test but dint lecture on it bec nurses dont teach u everything u need to know in nsg schl. something like that.

why nsg instructors, who are responsible for educating future nurses, hold this philosophy is beyond me. just thankful he doesnt take it to the xtreme my "instructors" (LOL) in the other program did. no comparison actually. that's a good thing. :)

notes from interwebs (not the text bc i dont have it w/me atm)...


*SENSORIMOTOR STAGE 0-2yrs
most in tune with sensorimotor stimuli; simple reflexes; circular reactions; beginning of mental/symbolic thought; understanding by coordinating sensory experience w/ motor action; knowledge of world via interacting with environment; problems with object permanence resolved by end of this stage

*PRE-OPERATIONAL STAGE 2-7yrs
begin grasping language, prone to fantasy, perspective is self-oriented, substitutes objects with symbols, able to think about things not happening now, thinks outside world, play pretend, think operantions through but only in one direction; difficulty seeing POV of others;
-SUBSTAGES
-----SYMBOLIC FUNCTION SUBSTAGE: egocentric thinking (only understands own POV), can formulate designs of objects not present, language, pretend play
-----INTUITIVE THOUGHT SUBSTAGE: primitive reasoning, knowledge but only know it intuitively, fails at conservation-of-liquid tasks*

*CONCRETE OPERATIONAL STAGE 7-12yrs
begins abstract reasoning; able to mentally manipulate info; begins solving hands-on prolems in logical manner; understands laws of conservation, working backwards; appropriate use of logic;
-IMPORTANT PROCESSES: seriation (pattern gradients), transitivity (if a>b, and b>c, then a>c), classification, decentering (multiple aspects taken into account..eg, not just height of container), reversibility, conservation, elimination of egocentrism (can take other's POV)

*FORMAL OPERATIONAL STAGE 12 to adult
full comprehension; can make decisions w/o concrete objects; can consider multiple POV, can solve abstract problems; more scientific thinking (devising solutions and systematically test them); finds identity; begins to deal with social issues; can transcend beyond concrete experiences into abstracts/hypotheticals to solve problems and draw conclusions; can think about the future

kinda creepy. but interesting illustration of the stages. sensorimotor was best. then it becomes less relevant with each stage thereafter imo.
