Cross-sectional design: Will research participants behave naturally? - Age effects and cohort effects are confounded. Template by: commissio_nurse DEVELOPMENTAL PSYCHOLOGY ーCohort differences can tell us about the influence of the sociocultural environment on development. - Researchers learn nothing about how people change with age. - Quicker and easier than longitudinal studies Longitudinal design: - One cohort of individuals is assessed repeatedly over time. -Provides information about age changes rather than age differences -Can indicate whether the characteristics and behaviors measured remain consistent over time. Sequential design: -Combines cross-sectional approach and longitudinal approach in a single study -Can reveal Which age-related trends are developmental in nature Which age trends differ from cohort to cohort Time-of-measurement effects - Very complex and expensive Conducting Culturally Sensitive Research Baltes's life-span perspective emphasizes tai development is shaped by its cultural context. Most developmental research is WEIRD: - People living in societies that are Western, Educated, Industrialized, Rich, and Democratic Ethnocentrism can impact research. Protecting the Rights of Research Participants Research ethics: - Standards of conduct to protect research participants from physical or psychological harm - Federal regulations require organizations that conduct research with humans to have institutional review boards. Informed consent: - Must be voluntary. - Obtain at least the "assent" or agreement of the individual in vulnerable populations. - Must not to pressure anyone to participate - Must respect participants' right to: *Refuse to participate. *Drop out during the study. *Refuse to have their data used by the investigator. Debriefing: - Tell participants about the study afterward if they are not told everything in advance or are deceived. -Explain the true purpose of the study. ーObligation to make sure that participants do not leave feeling upset Protection from harm: - Researchers are bound to not harm research participants either physically or psychologically. - If harm seems likely, researcher needs to find another method. - Federal regulations provide extra protection from harm to children. Confidentiality: - Ethical responsibility to keep the information collected confidential - Information collected can be shared only if: * Participants give explicit permission. *Law requires disclosure of information.
