Abstract

V originále

In this study, we tested the hypothesis that experimental stress induces a specific change of left-right electrodermal activity(EDA) coupling pattern, as indexed by pointwise transinformation(PTI). Further, we hypothesized that this change is associated with scores on psychometric measures of the chronic stressrelated psychopathology. Ninety-nine university students underwent bilateral measurement of EDA during rest and stressinducing Stroop test and completed a battery of self-report measures of chronic stress-related psychopathology. A significant decrease in the mean PTI value was the prevalent response to the stress conditions. No association between chronic stress and PTI was found. Raw scores of psychometric measures of stressrelated psychopathology had no effect on either the resting levels of PTI or the amount of stress-induced PTI change. In summary, acute stress alters the level of coupling pattern of corticoautonomic influences on the left and right sympathetic pathways to the palmar sweat glands. Different results obtained using the PTI, EDA laterality coefficient, and skin conductance level also show that the PTI algorithm represents a new analytical approach to EDA asymmetry description.
