Document Summary
Piaget"s theory: 4 major stages (you do not need to know the sub-stages) Sensorimotor 0-2 yrs, learn to distinguish self from world, basic symbols (language) Preoperational 2-7 yrs, mental representation of objects, egocentric, focus on one dimension of problem. Concrete operational 7-12 yrs, can apply logical operators to concrete information but not abstract, hypotheticals. Formal opera5onal 12+, mature thinking, hypothetico-deductive (scientific) reasoning. General skills in preoperational, concrete and formal operational stages according to piaget (above) Compensation: a change in one dimension compensates for a change in another; increase in length of row is due to space in between coins. Reversibility: changes can be reversed; can make the longer row shorter again. Reasons children fail piagetian tasks: children lack the requisite cognitive structures. Piaget"s theory, operators: children have the requisite cognitive structures, but lack other knowledge that the task tests. Memory, attention, and ecoding: children don"t understand which elements of the task are relevant.
