However, sound and attention can also change pupil size, therefore, we must eliminate anything affecting behavior. For example, install a sound-proof booth.-NO is never used Advantages-Determines the cause Disadvantages-Artificial situation. Only can be observed in the lab, not the real world.-A natural stimulus is not present, recreated environments are not real enough. Caution: Boundary conditions-Looks at stereotyped, fixed action-Good control, independent variable-But, conditions held in research may not be conditions in generalization-Behavior stamped into species, e.g. carnivorous beetle attacks tadpoles. Prediction is that beetle is hungry, uses visual perception to catch tadpole.
