Psychophysiological responses during reading texts of different levels of complexity

We studied how cognitive load during reading different texts is reflected in psychophysiological responses. The results of the study showed that subjective difficulty of the text and the estimated level of invested mental effort are good indicators of differences in text complexity, whereas physiological measures show a high degree of interpersonal variability and are therefore, with the exception of the number of peaks in the amplitude of skin conductance (SCR) and heart rate, less reliable in differentiating the texts.

Physiological changes during intelligence test

The study aimed to determine the manner in which physiological parameters change during solving an intelligence test task. Since problem solving is both a psychological and a physiological process, physiological responses are triggered by stress, emotions and cognitive activity. To determine the physiological response pattern, heart rate, blood pressure, skin conductivity and temperature and respiration rate were measured. From the signals obtained, selected measures of physiological changes were calculated. The subjects attempted to solve six tasks from the Raven’s Advanced Progressive Matrices of three difficulty levels, which were chosen on the basis of a previous result on the Standard Progressive Matrices. Additionally, subjects’ anxiety was measured by the State-Trait Anxiety Inventory (STAI). Apart from blood pressure, physiological parameters significantly discriminated between tasks of different difficulty. Using multiple factorial analysis (MFA), a measure of each parameter was chosen which discriminated between experimental conditions best. Physiological parameters had similar discriminating power. Anxiety was not found to be associated with physiological reactivity. Some guidelines for measurement, analysis and usability of physiological data were outlined. This thesis was awarded by the University of Ljubljana's Prešeren Award in the study year 2015/16.

Measuring the effect of classification accuracy on user experience in a physiological game

Physiological games use classification algorithms to extract information about the player from physiological measurements and adapt game difficulty accordingly. This paper studies how the classification accuracy affects the overall user experience and how to measure this effect. We observed that the classification accuracy must be at least 80% for the physiological game to be accepted by users and that there are notable differences between different methods of measuring the effect of classification accuracy.
