Mesosystem Examples: The Bridges Connecting a Child’s World

A second grader is falling behind in reading. His teacher notices the struggle within the first two weeks of the semester and calls home that same afternoon. His parents already suspected something was off, and within days the three of them have a plan: consistent phonics practice at home using the same method the teacher uses in class, weekly check-ins,...

7 Exosystem Examples That Shape a Child’s World

A mother gets passed over for a promotion. A school board votes to cut the art program. A neighborhood loses its only after-school center. None of these events happen anywhere near a child, yet each one changes that child’s day-to-day life.

She is reasoning exactly the way her brain is built to reason at that age. Piaget’s theory of cognitive development is the reason psychologists can explain, and predict, moments...

John Bowlby’s Theory of Attachment: Origins & Ainsworth’s 4 Types

A baby is left alone in an unfamiliar room for less than three minutes. What happens next tells researchers more about that child’s future relationships than almost anything else psychologists can measure. John Bowlby’s theory of attachment is the reason psychologists know to watch for it, and Mary Ainsworth is the one who figured out exactly what to look for....
