Research in Life-Span Development Flashcards
Process of Research
Gather data-observation, interview, test
Research-descriptive, correlational, experimental
Time Span-cross-sectional, longitudinal, cohort effects
Naturalistic observation
observing behavior in real-life settings w/out effort to manipulate or control the situation
standardized test
uniform procedure for administration & scoring
case study
in-depth look at a single individual
descriptive research
observe and record behavior
correlational research
describe strength of relationship between two or more variables
correlation coefficient
number based on statistical analysis used to describe association between two variables (higher the number, higher the correlation, whether positive or negative)
experiment
carefully regulated procedure in which one or more factors are manipulated while all others are held constant
cross-section
research strategy simultaneously comparing people of different ages
longitudinal approach
research strategy in which the same individuals are studied over a period of time, usually several years or more
cohort effects
due to a person’s time of birth, era, or generation (not to actual age)
informed consent
participants in experiments must know what it will involve and about risks, maintain right to withdraw for any reason
confidentiality
all data gathered on people must be kept confidential and (if possible) anonymous
debriefing
after completion of the study, participants must be informed of the purpose and method of it
deception
If keeping the method or purpose of a study a mystery is necessary to keep from tainting the results, no harm must come to the participants and they must be debriefed.
