Piaget's cognitive development theory states that children's thinking develops through stages from sensorimotor to formal operations. Young children around ages 6-7 think concretely and cannot understand concepts like equal amounts if divided into smaller containers. Vygotsky's sociocultural theory is that development is influenced by cultural and social values passed down through generations. Both theories see development occurring in stages influenced by brain growth, heredity, and experiences. However, Piaget views development as discontinuous with distinct stages while Vygotsky sees it as both continuous and discontinuous.

1. Cognitive Development
The systematic observation theories Iselected are;Cognitive Developmentby Swiss Theorist,Jean,and
Piagetand Sociocultural Theory by Russian Theorist,Lev Vygotsky. Per Piaget’s cognitive developmenttheory, all
development takes place in stages,(Piaget,1930). When viewing the picture in the textbook, it showed two young
children,ages 6 and 7. The children were pouring the milk into the large bowl and having to transfer the milk to the 4
smaller containers,they interpreted it to be smaller amounts. Theorist,Piagetcame to the conclusion thatchildren
under the age of 7, preschoolers,thinking are full of faulty logic,(Piaget, 1930). This is due to the stages and the
developmentofthe brain starting at the sensorimotor stage,developing to the preoperational stage and advancing to
the concrete operational stages,being school aged children and on to the formal operational stage where your
thinking is more abstract,advanced, higher level thinking. So, children at the age of 7 or 8 would understand thatthe
milk level would still be the same amounteven if divided into smaller containers.
My second theory is Sociocultural Theory by Russian theoristLevVygotsky. This theory is about the lives
and cultures of individuals such as;values,beliefs,customs and skills passed on to generations. Children generally
will pick up the ways of their parents,guardians or someone theyadmire the most. Children will develop into certain
stages per theorist,(Vygotsky, 1935).
I view human developmentbased on the sociocultural theory. I value life and have different beliefs than
mostof my friends and this is due to how I was raised. We all have different beliefs values,cultures. As I matured in
life I have held on to whatmy parents have instilled in mybut I stepped a little out of the box, never disrespecting my
parents butexplored different information and ideas.
Similarities /differences: Both theories discontinues,take place in stages.Brain growth and heredity
contribute to development. Both early and later experiences are importantstages.The sociocultural theoryis both
continuous and discontinuous and one course ofdevelopment,while the cognitive developmenttheory is
discontinuous and has manycourses ofdevelopment,(Piaget,1930).
PersonalityDevelopment: When looking at the personalities Ithink of the Efe children of the Congo’s
sharing food at the young infant stages,which shows the sociocultural value and cultural relations .
