Unit 2 Flashcards
What are findings vs interpretations?
Findings are the data/information that is collected whereas interpretations are the meaning of the findings.
What is an experimental design?
A study in which researcher administers the potential casual variable. Comparison groups are identical on everything but the treatment.
What is a correlational design?
A study in which the researcher observed and records data as it unfolds. Researchers look at naturally existing relationships.
What is a cross-sectional design and how is the data collected?
A design allows us to study groups of people of different [cohorts] at a single point in time.
Data is collected at one time point from multiple cohorts.
What is a longitudinal design and how is the data collected?
A design which collects data from the same individual over multiple timepoints.
What is a sequential design and how is the data collected?
A sequential design is the combination of cross-sectional and longitudinal designs.
What is a pro and con of the experimental method?
Pro: The method can establish a cause-effect relationship.
Con: May not work this way in the real world and there are many variables that can’t be manipulated or duplicated in an experimental setting. “Not everyday life”
What is a pro and con of the correlational method?
Pro: Data can be collected in natural settings and may be more applicable to the real world.
Con: This method cannot prove a cause-effect relationship and we can only look at what exists already. “No causation”
How can we address the limitations of experimental study designs?
Researchers can conduct experiments in the field (outside of the lab.)
How can we address the limitations of correlational study designs?
Researchers can add time by examining beginnings and adding time sequences.
What are the pros/cons of cross-sectional design?
Pro: We can gather information about age differences. It is practical.
Con: The data doesn’t tell us about changes within individual people - only large groups.
What are the pros/cons of longitudinal design?
Pro: We can see how individuals develop over time (we can detect patterns of stability/change) and we can see if earlier experiences affect later development.
Con: It’s expensive and time consuming.
What are the pros/cons of sequential design?
Pro: Can detect/rule out cohort effects, can learn how historical/cultural influences might shape development, and provides the most complete information for developmental research.
Con: Complex, time-consuming, expensive, generalizable to cohorts studied, and no casual inferences.
What are cohort effects?
Some differences between people born in different years may not be developmental and it may be due to unique historical-cultural experiences. IE Differences between groups of people who have had the same set of experiences.
What are historical effects?
Some changes within a person over time are caused by history, not by development.
