Comparison of physiological / neurophysiological and declarative responses in the evaluation of verbal, pictorial and contextual stimuli

Original language description

The CA method (Colour Association Method) is a combined projective technique based on the principles of the Lüscher colour test and word associations. It uses calibrated sets of words or visual objects (i.e. stimuli) and a palette of eight colours. Stimuli provoke an immediate association with which the person is instructed to react via colours. As associations cannot be disrupted or influenced rationally, the CA method focuses on measuring and evaluating &apos;authentic uncensored associations&apos; and provides a different quality of information compared to the commonly used questionnaire. This study aims to examine how well the CA method and the questionnaire are able to capture the responses of humans, approximated by their physiological reactions, to different stimuli. A sample of 101 individuals was used for this purpose, where each of them was exposed to 145 different stimuli. First, physiological responses to stimuli (cerebral blood flow, electrical activity of the brain, variability of heart rate, and response to skin con-ductance) were measured at the Multimodal and Functional Imaging Laboratory (MAFIL), Czech Republic; subsequently, the perception of stimuli was measured using the CA method and questionnaire. These data make it possible to evaluate the ability of the questionnaire and the CA method to capture an individual&apos;s responses to stimuli, including their emotional charge, which is a condition for the unbiased measurement of many important psychological concepts (i.e. health-related quality of life, satisfaction with different types of public and private services, attitudes etc.) Our investigation focused on five related topics: a) relationship between the CA method and the questionnaire, b) relationship between the CA method / questionnaire categories, heart rate and skin conductance, c) relationship between the CA method / questionnaire categories and brain activation measured by fMRI, d) reliability of measurement in time, especially with focus on questionnaire and CA method, e) the validity of questionnaire and CA method measurement.
