Question

Quizplus · Accepted Answer

The dependent variable in the Hess (1975) experiment was attractiveness, as this was the outcome variable being measured and hypothesized to be affected by changes in pupil size. The independent variable was pupil size, as it was being manipulated to test its impact on attractiveness. Confounding variables are factors that could potentially affect the outcome variable but are not being directly manipulated or controlled for in the experiment. A subject variable refers to an individual characteristic of participants that cannot be manipulated, such as age or gender, and is therefore not relevant to this specific experiment.
