Fyziologické koreláty a sémantické vzdálenosti ve slovním asociačním experimentu

Lukavský, Jiří

The project is focused on the physiological reactions during Word Association Test (WAT). The author tests the hypothesis originally proposed by Slechta (2002b) about separable cognitive and emotional workload, where · the cognitive workloads manifests in reaction times (RT) and emotional work- load in physiological reactions (e.g. electrodermal activity). The hypotheses were tested on the sample of young healthy adults (N=80), with protocol consisting of 40 Czech nouns. The stimuli varied in their level of concrete- ness and their emotional valence. During the experiment RTs, electrodermal activity (EDA) and pupillary responses (PR) were measured. Data support the original ndings that RTs and EDA reactions reřect in WAT di®erent situation requirements: cognitive workload and emotional workload, respectively. The e®ect of cognitive workload is larger and mani- fests also in EDA reactions, while EDA demonstrated the best sensitivity to emotional valence condition from all employed methods (RTs, EDA, pupil- lary reactions). The e®ects are unfortunatelly too small to allow a reliable classication of responses. The e®ects of other factors (subjective valence, corpus frequency of re- sponses, semantic proximity measured with Semantic Selection Test) were investigated, but even when signicant correlations were...
