(1) Participant Variables: This refers to anything specific to the participant that could affect the results of the research, for example, a participant’s age, gender, intelligence, personality etc (2) Demand Characteristics: This refers to environmental clues and cues in an investigation that cause participants to behave unnaturally.
Identifying Participants Variables, you can choose age, occupation, gender, ethnicity, socioeconomic status, literacy status, etc. as your variables. Example - Research Question: How does the age of a person affect the way they cope with stress (or what stress coping mechanisms they use)? You may pick age, occupation and gender as the variables.
Extraneous variables fall into three types: Participant variables are differences between the participants themselves. Obviously, everyone's different and most participant variables (height, birthday, number of siblings) don't make much difference to a study, but others (intelligence, level of education, personality) might make a big difference.
Researcher variables – factors such as researcher behaviour, appearance or gender could affect participant responses, so should be made consistent throughout the experiment. Situational variables – control of the setting where the experiment takes place, such as keeping light, sound and temperature levels consistent.
Participant variables (also known as subject variables) are the differing individual characteristics of participants in an experiment. These variables are plentiful and varied including things such as age, background, socioeconomic status, current mood, how much sleep the individual person got the night before, and many more.
Variables in psychology experiments are fundamental components that researchers manipulate or measure to understand psychological phenomena. In experimental research, the independent variable is the factor that is deliberately changed to observe its effect on another factor, known as the dependent variable, which is the outcome being measured.
Participant Variables: Psychology. Participant variables are individual traits of a participant that could affect their performance in the experiment. Some examples of these are gender, age, intelligence and socioeconomic status. There are a few different ways to reduce extraneous variables, these are:
In psychology, a dependent variable represents the outcome or results and can change based on the manipulations of the independent variable. Essentially, it’s the presumed effect in a cause-and-effect relationship being studied. An example of a dependent variable is depression symptoms, which depend on the independent variable (type of therapy).
Researchers need to identify and control these variables to avoid invalidating their findings. Below are some of the most common types of extraneous variables: 1. Participant Variables 🔗. Participant variables refer to characteristics or traits of the individuals in the study that could influence the outcomes.
This variable is what the researcher manipulates or changes. So, in the instance of the example above regarding driving a car, the independent variable is if the participant is a man or a woman, as this is the thing that changes and it is this that determines if the dependent variable will be affected. Other examples might include:
Extraneous variables are all the other variables that could influence the dependent variable but are not of primary interest in the study. These could include factors such as the environment, the time of day the study is conducted, or individual differences like a participant’s prior knowledge or mood.
A confounding variable is an extraneous variable that differs on average across levels of the independent variable (i.e., it is an extraneous variable that varies systematically with the independent variable). For example, in almost all experiments, participants’ intelligence quotients (IQs) will be an extraneous variable.
Examples of variables in psychology include age, gender, intelligence, and stress levels. Understanding variables is essential for interpreting the results of psychological studies and for the advancement of psychological theories and practices. ...

In psychology, variables are categorized into different types based on their characteristics and measurement scales. ... the participant and the victim are accompanied by a group of either three or six bystanders. In this case, the independent variable is the number of potential helpers on the scene besides the participant, and the levels are ...
An extraneous variable is anything that varies in the context of a study other than the independent and dependent variables. In an experiment on the effect of expressive writing on health, for example, extraneous variables would include participant variables (individual differences) such as their writing ability, their diet, and their shoe size.
