The factor under investigation in an experiment that is manipulated to create two or more conditions (levels) and is expected to be responsible for changes in the dependent variable.

• Independent Variable (IV)

• Dependent Variable (DV)

• Experiment

• Participant Variablees

The factor in an experiment that is measured and is expected to change under the influence of the independent variable.

• Independent Variable (IV)

• Dependent Variable (DV)

• Experiment

• Participant Variables

A variable that acts randomly or systematically and makes the effects of the independent variable difficult to interpret, if they cannot or have not been eliminated.

• Uncontrolled Variable

• Experimental Condition

• Control Condition

• Experimental Design

The levels of the independent variable being compared may be 2 or more _____________ ____________ (such as bright and dull artificial lights), or there may be 1 or more compared to a ____________ ____________ (artificial light compared to daylight).

• experimental conditions ; control condition

• control conditions ; experimental condition

• uncontrolled variables ; demand characteristic

• demand characteristics ; uncontrolled variable

In a research study to better understand aggression, two groups of adults are compared. The first group was never exposed to aggressive television. The second group was exposed to aggressive television. This is an example of which type of research design?

• Independent measures design

• Repeated measures design

• Random allocation

• Confounding variables

_________ _________ is a way to reduce the effect of confounding variables such as individual differences; each person has an equal chance of being in any condition.

• Random allocation

• Demand characteristics

• Participant variables

• Confounding variable

When participants' performance improves because they have encountered the task before.

• Practice effect

• Fatigue effect

• Randomization

• Counterbalancing

For each participant, another person is found who is similar in important ways to the experiment. Type of research design?

• Matched pairs design

• Reliability

• Validity

• Pilot Study

A difference between laboratory experiments (LE) and field experiments (FE) is:

• LE are not conducted in the participants' typical environment for the behavior under study ; FE are conducted in the participants' typical environment.

• LE are conducted in the participants' typical environment for the behavior under study ; FE are not conducted in the participants' typical environment.

A benefit of laboratory experiments (LE) is:

• LE use many controls as ways to keep potential confounding variables constant and standardization to keep the same procedures for each participant. This can increase the reliability of the findings.

• LE occur in the typical place in which a participant shows a behavior, making the results more natural and standardized.
