Research Designs and Experimental Psychology

These flashcards cover key concepts in research designs and experimental psychology based on the lecture notes.

Wilhelm Wundt

A German physiologist and psychologist acknowledged as the founder of experimental psychology.

Experimental Psychology

A branch of psychology that utilizes experimental methods to study the mind and behavior.

Contribution to the Theory of Sense Perception

A work written by Wundt in 1862 that laid foundational ideas for psychology.

Correlational Design

A research design that examines the relationships between variables without manipulating them.

Correlation Coefficient (r)

A statistical measure that describes the strength and direction of a relationship between two variables.

Independent Variable

The variable that the researcher manipulates or controls in an experiment.

Dependent Variable

The variable that is measured in an experiment to assess the effect of the independent variable.

Random Assignment

A method used to assign participants to different conditions or groups in a study by chance.

Placebo Effect

A phenomenon where participants' expectations about a treatment can influence their outcome.

Double-Blind Procedure

An experimental method in which neither the participants nor the experimenters know who is receiving a particular treatment.

Quasi-Experimental Design

A research design that lacks random assignment, using fixed independent variables.

Longitudinal Studies

Research studies that involve repeated observations of the same variables over time.

Causation vs Correlation

Causation implies that one event causes another, while correlation indicates a relationship without implying cause.

Confounding Variable

An outside influence that can affect the results of an experiment and lead to erroneous conclusions.

Survey

A research method that gathers information from participants through questionnaires or interviews.
