Big questions about development.


Morality: origin of moral thought, we start off as immoral or amoral - Hobbes & freud believe we start off as animals - Jean-jacques Rousseau believes we’re basically good and culture corrupts Continuity: What’s the relationship between between children and adults? - How much of who we end up is set by genes? Cognitive development: How much of what we know now are we born with and how much we have to learn? - Empiricism - We start off at empty and then we learn and learn and learn. - Nativism - We are born with rich powerful structure systems in our brain. - Constructivist - Learning, interaction, dealing with environment, makes us who we are



Genetic epistemology

  schemas:“So what did Jean Piaget have to say? Well, he thought of children as active thinkers. He may call them little scientists trying to make sense of the world. And he described these understandings as schemas. And schemas were mental systems”

Methods for studying infants



- Brain scans - Sucking - if you wanted to know if a baby prefers A or B put a pacifier in their mouth when they suck on the pacifier the response is A the baby will eventually learn sucking on pacifier leads to A response so it will suck on the pacifier if it prefers A and won’t if B - Looking - Showing a series of pictures of similar things you become bored if it’s three dogs, three cats (cont) once bordem sets in if you switch to two dogs, two cats and the subject becomes interested again which shows you understand two dogs =/= three dogs it’s different and interesting - Some studies on infants show they do have object pertinence Karen Wynn (toy addition/subtraction test)

  Paul Bloom & Karen Wynn did an experiment trying to display morality in babies, the babies where shown two puppet plays, one containing a moral character and one an immoral character they were then asked to choose which character (puppet) they want to play with and they chose the moral puppet


Developmental differences


One way in which adults and children are different is children (3yrs) are less capable of deception due to struggles with comprehending people can be fooled but a child of just one year older can, which leads to him being able to understand he can think and know things others don’t - to test this there is the sally & anne test[1]


How do we explain development?


A modular concept for development



The brain contains specific modules for
