Developmental Psychology Flashcards
What is the difference between qualitative and quantitative theories of developmental change?
Qualitative developmental theories see development as discontinuous, with there being specific times of significant developmental growth and change. According to qualitative theorists, if you don’t master a stage-specific issue, you become at risk of future developmental failures. Quantitative theorists view development as continuous and gradual. The only difference between children and adult abilities is the amount of things they are able to do. There are no qualitative differences.
