What are the contributions of Charles Darwin to developmental psychology? | One of the most influential 'baby biographers.' His fascination with evolution is what led to him wanting to learn more about children's development. His evolutionary perspective strongly influenced early theories of human development, which emphasized universal, biologically based maturational changes |
What are the contributions of G. Stanley Hall to developmental psychology? | (founder of developmental psychology) He was greatly influenced by Darwin, and was the first president of the American Psychological Association he also developed the questionnaire to explore the contents of children's minds at different ages and wrote an influential book called 'Adolescence'- they are emotionally unstable |
7 key life-span assumptions | 1. development is a lifelong process
2. development is multi-directional (lose, gain, stay stagnant)
3. development involves both gain and loss (think of when you learned english... you started losing some spanish)
4. development is characterized by lifelong plasticity (changes in response to neg. or pos. experiences )
5. development is shaped by its historical culture and contents (Great Depression...how it affected who we are today)
6. development is multiply influenced (part of nature/nurture...influenced by everything)
7. development is studied by multiple disciplines (it is impossible for one discipline to have all the answers) |
scientific method | both a method and an attitude that investigators should allow their systematic observations (data) to determine the merits of their thinking |
operational definitions | Specific explanations of abstract concepts that a researcher plans to study, defined by how they are measured. |
validity | The extent to which a test or tool measures what it claims to measure. |
reliability | The consistency or repeatability of a measure or test over time. |
random sample | picking randomly or blindly from a larger population (helps increase confidence that data you're collecting is truly representative of the larger population of interest) |
population | well defined group from which a sample is taken out of to make conclusions |
methods of data collection | 1. verbal reports
2. behavioral observation
3. psychological measurement |
