TERM 1
Advantages of Experiments
DEFINITION 1
1. Evidence of causality 2. Control (isolate variables, focus,
internal validity) 3. Lower cost 4. Replication (often repeated)
TERM 2
Disadvantages to Experiments
DEFINITION 2
1. Artificiality (much behavior of intere st is altered when studied
out of its natural environment... resu lts may have little direct
application to real world settings) 2. Re activity (people know
they're being studied so they behave differently) 3. Experimenter
bias (double blind overcomes this bias) 4. Limited scope (b/c of
narrow focus and control) -i.e. cultiva tion hard to study in a lab
TERM 3
Experimental Research
Involves...
DEFINITION 3
1. Manipulating the IV and then obser ve the responses of subjects
on the DV 2. Select the setting 3. Se lect the experimental design
4. Operationalize the variables 5. Dec ide how to manipulate the IV
-Straightfoward manipulation -Staged manipulation 6. Select and
assign subjects randomly to experime ntal conditions 7. conduct
pilot study 8. Administer the experime nt 9. Analyze and interpret
the results
TERM 4
Straightfoward Manipulation
DEFINITION 4
real world IV differences are use din the experimental
session
TERM 5
Staged Manipulation
DEFINITION 5
the researcher creates IV differences to maximize
manipulation for the purposes of the experimental session
