| Popis: | The present project investigates the neurophysiological processing of auditorily presented words in relation to ratings of their valence and arousal. Valence (ranging from positive to negative) and arousal (ranging from low to high) are used here, as in previous studies, to operationalize the ‘emotional load’ of word concepts. Both factors have been shown to correlate with specific brain and/or pupil responses. The novelty of the current study is given by the fact that we use the exact same data acquisition method, data modeling approach, as well as carefully matched stimulus materials across two languages, German and Czech. 114 German words and their Czech translation equivalents will be presented to native German speakers (in German), and native Czech speakers (in Czech) auditorily. Words from both languages were initially selected based on previously obtained ratings of valence and arousal (in Vo et al., 2009 for German and in Preininger et al., 2022 for Czech) so as to keep the Euclidian distance between word pairs (same word concept or translation equivalent in German and Czech) in the two languages as minimal (≤0.5) as possible. Thus, the stimulus set contains words that have approximately the same meaning in both languages and that do not differ with respect to their valence and arousal ratings, at least as determined by the two previous studies. The auditory stimuli to be used in the current study were created using Text-to-Speech synthesis with neutral prosody and matching speech rate for both languages. In each trial, participants will listen to each individual word. Pupil dilation and hemodynamic responses will be measured simultaneously over a pre-specified time interval. At the end of each trial, participants will provide valence and arousal ratings. The goal of this study is two-fold: At the neurophysiological level, we aim to differentiate responses to words with different emotional load in speakers of two languages. At the behavioral level, we investigate individual differences regarding valence and arousal ratings by comparing our participants’ ratings with the average ratings obtained in the two previous large-scale rating studies. We expect to find stable neurophysiological patterns that correlate with valence and arousal ratings across both languages. More specifically, based on previous research, we hypothesize to find hemodynamic correlates mostly to ratings of valence, and pupil size correlates mostly to ratings of arousal. The more extreme the valence and/or arousal, the larger neurophysiological responses are expected. Since we expect the magnitude of hemodynamic responses to depend on emotional load, neurophysiological responses of Czech and German speakers to words with similar emotional ratings should be comparable. |
