Question: 1 / 400

Which psychophysical method allows participants to control stimulus intensity?

Method of Adjustment

The Method of Adjustment allows participants to control the intensity of a stimulus directly. In this method, individuals are given the ability to adjust the levels of a stimulus until they reach a specific threshold or match a reference stimulus. This hands-on control makes it easier for them to find the point at which they perceive a change or notice a difference, leading to more personalized and potentially accurate measurements of sensory perception.

This approach emphasizes the subjective experience of participants, as they guide the experiment through their adjustments, allowing for a nuanced understanding of how stimulus intensity correlates with perception. By contrast, the other methods each have distinct procedures, such as presenting a set of stimuli in variations without participant control or measuring responses to fixed intensities, which do not allow the same level of direct interaction with stimulus intensity.
