Questionnaire and Projective Color Association in Physiological Responses to Different Emotional Charge

NCT05363852 | Completed

• 1 other identifier: LFOU10/2021
• Study Type: interventional
• Target: 101
• Locations: 1 country
• Sites: 1

Brief Summary

A sample of 101 individuals will be used for this purpose, where each of them will be exposed to 145 different stimuli. Comparison of their physiological responses to stimuli (cerebral blood flow, electrical activity of the brain, heart rate variability, and skin conductance response) and the perception of the stimuli measured by the questionnaire and CA method will make it possible to identify the method that provides more accurate information on the real perception of the stimuli. These findings may have important consequences for the use of the questionnaire and the CA method to measure different psychological concepts.
