Chapter 2: Conducting Research in Psychology Flashcards
What are the 5 procedures of the scientific method?
Observe, Predict, Test, Interpret, Communicate (OPTIC)
What is scientific thinking?
Using the cognitive skills required to generate, test, and revise theories
Theory
Set of related assumptions from which scientists can make testable predictions
Hypothesis
A specific, informed, and testable prediction of the outcome of a particular set of conditions in a research design
Replication
The repetition of a study to confirm the results; essential to the scientific process
Pseudoscience
Refers to claims that are presented as scientific that arent supported by evidence used with the scientific method
Research designs
Plans of action for how to conduct a scientific study
What is are some examples of pseudoscience or fake psychology?
Astrology, Graphology, Palmistry, Phrenology
Variable
A characteristic that changes or varies, such as age gender weight intelligence anxiety extraversion
Population
The entire group a researcher is interested in; for example all humans, all boys, all girls
Sample
Subsets of the population studied in a research project (instead of all college students, research only black campuses)
What is used more in research, population or samples
Samples
Descriptive designs
Study designs in which the researcher defines a problem and variable of interest but makes no prediction and does not control or manipulate anything
Naturalistic observation
A study in which the researcher unobtrusively observes and records behavior in the real world
Case study
A study design in which a psychologist, often a therapist, observes one person in depth over a long period of time (or group or event)
Representative sample
A research sample that accurately reflects the population of people one is studying
Correlational design
Studies that measure two or more variables and their relationship to one another; not designed to show causation
Experiment
Research design that includes independent and dependent variables and random assignment of participants to control and experimental groups or conditions
Independent variable
The variable that is manipulated under controlled conditions
Dependent variable
Outcome or response to the manipulation
For variables, which is the cause and which is the effect?
Independent - cause
Dependent - effect
Random assignment
The method used to assign participants to different research conditions so that all participants have the same chance of being in any specific group
Experimental group
The participants in random assignment that will receive treatment or whatever is predicted to change behavior
Control group
Participants treated just as same in experimental group but do not receive independent variable or treatment. Mostly get no special treatment or a placebo (appear identical treatment but not active substance in treatment)
Confounding variable
Variable whose influence on the dependent variable cannot be separated from the independent variable being examined
