Research & Evaluation of Scientific Studies of Development Flashcards
1
Q
Scientific Method
A
- Observations
* Theories
2
Q
What is a theory?
A
- Logical system of general concepts that provide framework for organizing & understanding observations
- Attempt to organize & summarize existing facts
- Should be TESTABLE
3
Q
What is a hypotheses?
A
- Prediction tested in research
* Based on theoretical perspective or observation
4
Q
What are the characteristics of research?
A
- Systematic
- Objectivity
- Measurebility
5
Q
Systematic
A
• Have a plan before conducting the research
6
Q
Objectivity
A
• Researchers work to reduce bias
7
Q
Measurebility
A
- Reliability
- Validity
- Replicable (other researchers who use the same method should get the same result)
8
Q
What types of studies can be conducted?
A
- Descriptive studies
- Case studies
- Correlational research
- Experimental research
- Quasi-experimental research
- Cross-sequential research
- Longitudinal
- Cross sectional
9
Q
Descriptive studies
A
- Description of observations
* In the lab or in the field
10
Q
Case Studies
A
- Research involving a single individual, group or family
- Limited generalizability/external validity
- USEFUL WHEN THERE IS A LIMITED NUMBER OF PARTICIPANTS (ex. phineas gage’s case)
11
Q
Correlational study
A
- Widely used in developmental studies
- examines relationship btwn. 2 or more variables
- Positive correlation
- Negative correlation
- Scatterplots demonstrates degree of correlation
12
Q
What is the correlation coefficient?
A
-1≤v1
13
Q
Experimental Research
A
- Examines cause & effect by manipulating variables
* Systematically change 1 variable to examine the effect on the other (IV & DV)
14
Q
Quasi-experimental
A
• like experimental, but targeting a group
15
Q
Longitudinal
A
• Study of changes overtime • Disadvantages - Attrition: ppl dropping out of the study - outdated mesures - $
