Key Takeaways

  • Developmental Psychology was originally concerned with infants and children but has expanded to include adolescence, aging and the entire life span.
  • Development can be understood from a physical, cognitive and psychosocial perspective.
  • Periods of development can be analyzed using discontinuous theories which postulate qualitatively different stages. These theories contrast with continuous theories that hypothesize development as the result of incremental quantitative changes.
  • Lifespan development can be studied using various research methods including descriptive, correlational, and experimental paradigms. Each paradigm can also be seen through research designs such as longitudinal, cross-sectional and sequential data collection methods.

  2. How do you think indigenous perspectives on development might inform our own ideas about a lifespan perspective?
  3. Go through different research methods that we have discussed and list the advantages and disadvantages for each.
