|
Authority |
Media |
|
Empiricism |
Knowledge through observation and experiment |
|
Determinism |
All behavior has an identifiable cause |
|
Parsimony |
Simple explanation is most accurate and concise |
|
Testability |
Ideas only tested through observation through scientific method |
|
Basic research |
Understand fundamental behaviors |
|
Applied research |
Helps solve real world problems |
|
Randomization |
Participants are randomly assigned to levels of the independent variable in an experiment to control for individual differences as an extraneous variable |
|
Types of Manipulation |
Presence/ absence Bivalent independent variable |
|
Presence/ absence |
Presence or absence of treatment or gender |
|
Bivalent independent variable |
Simplest type of independent variable. Independent variable with two levels. |
|
Comparison/ control |
Control group |
|
Manipulation |
Variable that operate in an experiment |
|
Reliability |
Consistency, ability, and repeatability |
|
Independent variable |
What's manipulated or what's causing the change |
|
Dependent variable |
Measured or observed |
|
Data collection techniques |
Survey/ questionnaire Interview Archival data Systematic observation |
|
systematic observation |
Observing behavior cognitive and biological |
|
NOIR |
Nominal Ordinal Interval Ratio |
|
Nominal |
Simple/ non ordered categories/ qualitative/ ex. Gender, race, mood |
|
Ordinal |
Ordered categories/ order of rank not equally spaced |
|
Interval |
Numerical response/ equally spaced/ likert scale |
|
Ratio |
Have absolute zero |
|
Beneficence |
Reduction of risk of harm to the participants and compared with the benefit of the study |
|
Respect |
Provides information about the study before it begins. Obtain voluntary consent from participant after they are informed |
|
Justice |
Selection of participants must be fair. All participant groups must have opportunity to receive benefits of research. |
|

|
Milgrams 1963 study |
Electric shocker. Most people did highest voltage |
|
IRB |
Institution review board |
|
Debriefing |
Answer questions and risks/ reduce harm/ protect after they have left |
|
Qualitative |
Non numerical/ varies by class |
|
Quantitative |
Numerical varies about amount |
|
Construct validity |
Accurate measurement |
|
Validity |
Choice of measurement/ accuracy/ high construct validity |
|
Cofounding variables |
Other explanation besides what being measured |
|
Experimental |
Randomization/ Manipulation/ comparison and control/ cause and affect |
|
Quasiexperimental |
Type of research design where a comparison is made, as in an experiment but no random assignment of subject to groups occurs/ relationships between pre-existing variables |
|
Nonexperimental |
Describes and predicts/ no Manipulation/ no control |
|
Internal validity |
How well study demonstrates cause |
|
External validity |
How well it applies outside the study |
