In Lampinen et al.'s (2014) experiment, which of the following variables are controlled?

In Lampinen et al.'s (2014) experiment, controlling the location and other environmental conditions is crucial to ensure that any observed effects are a result of the experimental manipulation rather than external factors. By keeping these conditions consistent across all participants, researchers can eliminate potential confounding variables that could impact the results. This control allows for a clearer interpretation of how the manipulated variables—such as the specific task or method used in the experiment—affect the outcomes.

Maintaining a consistent experimental environment enhances the reliability of the findings, enabling researchers to attribute differences in performance or responses directly to the independent variable being tested. This strategy is fundamental in experimental research, as it enhances the validity of the conclusions drawn from the study.
