Document Summary

Development: change in abilities over time: nature - as you get older, you mature, nurture - as you get older, you learn. Interactions between nature and nurture: nature determines the range, nurture chooses the alternatives. Stagelike development: development is discontinuous, there are stages separated by rapid growth, qualitative differences among stages (ex. Salmon looks the same as a baby and adult, only size changed) Normative vs individual development: normative, typical sequence of change, look for consistency, methodology is cross-sectional (compare kids at one age and kids at another age) Individual: consistency is not there, look at individual, methodology is longitudinal (takes too long to do, so more rare than cross-sectional) Brain development: 100-200 billion neurons at birth, neurons not produced after second trimester. Increase in weight (350-1400 g) due to glial cells and myelination (not due to addition of neurons: number of synapses increase rapidly, cortical development mirrors emergence of abilities, frontal lobe develops last.
