motor skills, and school performance
Fragmented sleep
Advances in cognition due to changes in gray

obesity.
Treatment: Diet, exercise, glucose-lowering
meds/insulin if resistant
Type 2 Diebetes (Insulin resistance)
3rd stage of Piaget’s theory
Concrete operations
Can read & interpret maps, follow routes, estimate distance & time
Spatial thinking
Better understanding of how factors interact.
Reasoning improves when linked to real-world
knowledge.
Causality
ordering along a dimension
(shortest → longest ; earliest → latest).
Seriation
if A<B; B<C; A<C.
Transitive inference
understanding the relationship between a whole & its parts (e.g., roses < flowers).
Class inclusion
particular (specific) → general
Inductive reasoning
general → particular (specific), appears earlier
Deductive reasoning
Understanding that properties remain the
same despite changes in form.
Conservation
3 principles of Coservation
a. Identity
b. Reversibility
c. Decentering
nothing added/taken away
Identity
mentally undo action.
Reversibility
