Psychology Research Jargon You Should Know

Applied Research

Applied researchis a type of research that focuses on solving practical problems. Rather than focusing on developing or investigating theoretical questions, researchers are interested in finding solutions to problems that impact daily life. For example, researchers focused on applied research might investigate which treatments for a psychiatric condition lead to the best outcomes. This research is directly applicable and can help people improve their day-to-day lives.

Basic Research

Basic researchis a type of research that involves investigating theoretical issues to add to the scientific knowledge base. While this type of research contributes to our understanding of the human mind and behavior, it does not necessarily help solve immediate practical problems.

Case Study

Acase studyis an in-depth study of a single individual or group. In a case study, nearly every aspect of the subject’s life and history is analyzed to seek patterns and causes for behavior.

Correlational Research

Correlational studiesare used to look for relationships between variables. There are threepossible results of a correlational study: a positive correlation, a negative correlation, and no correlation.

Cross-Sectional Research

Cross-sectional researchis a type of research method often used indevelopmental psychologybut also utilized in many other areas including social science, education, and other branches of science.

Demand Characteristic

Ademand characteristicis a term used in psychological research to describe a cue that makes participants aware of what the experimenter expects to find or how participants are expected to behave.

Dependent Variable

Thedependent variableis the variable that is being measured in an experiment. Researchers will vary one or more independent variables and then measure the dependent variable or dependent variables to determine if there were any changes as a result.

Double-Blind Study

Adouble-blind studyis a type of study in which neither the participants nor the experimenters know who is receiving a particular treatment. This helps eliminate the possibility that the researchers will give subtle clues about what they expect to find and influence the behavior of the participants.

Experimental Method

Theexperimental methodinvolves manipulating one variable to determine if changes in one variable cause changes in another variable. By using this method, researchers can determine if cause and effect relationships exist between different variables.

Hawthorn Effect

TheHawthorn effectis a term referring to the tendency of some people to work harder and perform better when they are participants in an experiment. Individuals may change their behavior due to the attention they are receiving from researchers rather than because of any manipulation ofindependent variables.

Independent Variable

Theindependent variableis the variable of interest that the researcher systematically varies. By varying the independent variable, the researcher can then measure the effect, if any, on the dependent variable. Doing this allows scientists to determine if there is a cause and effect relationship between two different variables. In other words, if changes in one variable lead to changes in another.

Longitudinal Research

Longitudinal researchis a type of research method used to discover relationships between variables that are not related to various background variables. These studies take place over an extended period of time such as several weeks, years, or even decades.

Naturalistic Observation

Naturalistic observationis a research method commonly used by psychologists and other social scientists. This technique involves observing subjects in their natural environment. This type of research is often utilized in situations where conducting lab research is unrealistic, cost prohibitive, or would unduly affect the subject's behavior.

Random Assignment

Random assignmentrefers to the use of chance procedures in psychology experiments to ensure that each participant has the same opportunity to be assigned to any given group.

Reliability

Reliabilityrefers to the consistency of a measure. A test is considered reliable if we get the same result repeatedly. For example, if a test is designed to measure a trait (such asintroversion), then each time the test is administered to a subject, the results should be approximately the same. Unfortunately, it is impossible to calculate reliability exactly, but there several different ways to estimate reliability.

Replication

Replicationis a term referring to the repetition of a research study, generally with different situations and different subjects, to determine if the basic findings of the original study can be generalized to other participants and circumstances.

Selective Attrition

In psychology experiments,selective attritiondescribes the tendency of some people to be more likely to drop out of a study than others. This tendency can threaten the validity of a psychological experiment.

Validity

Validityis the extent to which a test measures what it claims to measure. It is vital for a test to be valid in order for the results to be accurately applied and interpreted.
