Question

Quizplus · Accepted Answer

Physiological measures can provide a more accurate assessment of attitudes because people may not realise they are being assessed and may not be able to alter their responses. Self-report measures rely on the accuracy and honesty of participants, which may be influenced by social desirability bias or other factors. By contrast, physiological measures (such as heart rate or skin conductance) provide an objective measure of the body's response to stimuli, which can be used to infer attitudes. Thus, using physiological measures can provide a more reliable and valid assessment of attitudes.
