RESEARCH IN DEVELOPMENT Flashcards
HOW DO YOU MEASURE DEVELOPMENT?
- Cross sectional design
- Longitudinal design
- Microgenetic design
WHAT IS A CROSS SECTIONAL DESIGN?
Comparing children of different ages at a single time
WHAT IS A LONGITUDINAL DESIGN?
Comparing children to themselves, examined over a period of time
WHAT IS A MICRO-GENETIC DESIGN?
Children are observed intensely over a short period
BENEFITS OF A CROSS SECTIONAL DESIGN?
Faster to collect data
Identify differences between age groups
WEAKNESS OF A CROSS SECTIONAL DESIGN?
Uninformative about stability of individual differences and individual differences over time.
BENEFITS OF A LONGITUDINAL DESIGN?
Watch development unfold
Can examine the individual differences over time
WEAKNESS OF LONGITUDINAL DESIGN?
Practice effects
Attrition rates (drop out rates)
Time consuming and a lot of resources.
BENEFITS OF MICRO-GENETIC DESIGN?
Very detailed
Intense observation can clarify the process of change
WEAKNESS OF MICROGENETIC DESIGN?
Must know when the change will occur
No long term data
3 WAYS OF DATA COLLECTION
Interviews, Naturalistic observation and Structured observation
BENEFITS OF INTERVIEW QUESTIONNAIRES
Inexpensive
Allows for flexibility to respond to unexpected answers
WEAKNESS OF INTERVIEW QUESTIONNAIRES
Biased or ingenue responses
Poor at predicting future
Relys on the child understanding the question
BENEFITS OF NATURALISTIC STUDY
Useful for describing behaviour and exploring social interaction
WEAKNESS OF NATURALISTIC STUDY
Lacks control
hard to know which element of the situation is influential
