Vygotsky - sociocultural 

Explanation of stages -  Vygotsky saw child development as consisting of passing through a series of periods of stable development, namely, infancy, early childhood, pre-school age, school age and puberty. These periods of stable development are punctuated by periods of crisis: at birth and at the ages of 1, 3, 7 and 13.

infants develop new social and cognitive skills through interactions with older individuals.

                     Skinner - psychosocial

American psychologist known for his impact on behaviorism. In a 2002 survey of psychologists, he was identified as the most influential psychologist of the 20th century.

B. F. Skinner himself referred to his philosophy as "radical behaviorism." He suggested that the concept of free will was simply an illusion and, instead, believed that all human action was the direct result of conditioning.

Learn about Skinner's many contributions to psychology one of the most well-known being operant conditioning, his theory of learning—his numerous inventions and publications, along with his biography to better understand who B. F. Skinner was.

I feel like it's ok 

                          Piaget - Cognitive, Psychosocial

Piaget's theory had a tremendous influence on the emergence of developmental psychology as a distinctive subfield within psychology and contributed greatly to the field of education. He is also credited as a pioneer of the constructivist theory, which suggests that people actively construct their knowledge of the world based on the interaction between their ideas and experiences. 

I don't have a really have opinion 

on this but kids do think different then adults do.

Bowlby- Psychosocial

There is a great deal of research on the social development of children. John Bowbly proposed one of the earliest theories of social development. Bowlby believed that early relationships with caregivers play a major role in child development and continue to influence social relationships throughout life.    

Bowlby's attachment theory suggested that children are born with an innate need to form attachments. Such attachments aid in survival by ensuring that the child receives care and protection. Not only that, but these attachments are characterized by clear behavioral and motivational patterns.

I agree because I feel like early childhood life is important and mental function.
