Definition of Developmental Psychology
aims to explain how children and adults change over time (socially and pyschologically)
History: 1700
children were seen as ‘mini-adults’; only quantitavely different
History: Enlightenment
John Locke + JJ Rouseau: children development studied
History: 1800’s
Charles Darwin + Evolutionary Theory: adaptation, change, variation and individual differences
Industrial Revolution + 19th-century history
Childhood literary and education begins to be studied
The 1920s History
Dev Pysch becomes a scientific dicisiplines; hwoever broken into ‘nature’ vs ‘nurture’ aspects
20th Century + Now (HIstory)
Who was Jean Piaget
a swiss scientists studied logical thinking in children from biological roots and came up with his ‘4 stages of development’ theory
John Locke
NURTURE; childs mind is a ‘tabula rasa’ at birth that sponges up experience
JJ Rousseau
NATURE: child develops due to a preconditioned biology
Genetic Epistemology Theory (2)
Piaget’s points of how knowledge is acquired in children:
4 stages of Cognitive Development
What happens in the Sensorimotor Stage
Birth- 2 years old
End: Object Permanence is Acquired After
Child:
What happens in the Pre-Operational Stage
2- 6 years old
End: Imagination/Experience grows and Chidl Decenters View
Child:
What happens in the Concrete-Operational Stage
7-11 Years
End: conservation, matthematical thinking and classification, ideas
Child:
What happens in the Formal Operational STage
12 years- Adulthood
End: acwuire ethics, politics and social/moral interests
Child:

How did Piaget study object permanence
Placed a screen before a 6 month year old baby; showed the object ‘didnt exist’ unless the baby saw it
What was Piagets ‘A not B’ Task
2 cloths and an objec:
researcher places an object under a cloth-> baby grasps for that cloth
then:
reseracher moves object to another cloth-> baby still goes for original cloth as existence of toy was dependent on its own actions
How did Piaget study Conservation
he asked a 6 year old if playdought ofo the same size/shape was the same amount
then changed the shape of one of the playdoughs in front of the child
child in pre-operational stage would say that the changed object is of a higher quanitity
Piagets ‘building blocks of thinking’
work by:
Assimiliation-> equilibrium (set of rules)–> novel situation (rules dont apply)–> disequilibirum–> acocmodation
Butterworth Criticisms of Piaget
Critiqued his idea that babies are egocentric.
Babies follow where mom is looking= which shows that the undersatnd the mom sees somethign they dont
Donaldson critique of Piaget
Found children COULD conserve earlier than piaget predicted:
—> used a ‘helper teddy’ that ‘changed the playdough’
Donaldson attributed that a child expects a change when researcher asks a question which influences their answer
Lev Vygotsky: what did he do/study
looked at the role of language in human society/thought
was a social ‘constructivist’; looked at how culture/society infleunces development
developed theory of scafolldly (kinds mind grows by interating with social elements and by paenting)
