Abstract: It is known that expressively presented stories are followed more attentively than neutral ones. However, it is currently unknown whether these effects generalize to virtual reality environments (VEs), which provide an opportunity to combine the reproducibility of laboratory settings with the complexity of every-day life communication. In this study we will focus on the relationship between likeability ratings of six different characters and attention depicted as cortical speech tracking via mobile electroencephalography (EEG). A total of 20 participants were presented audio-visual scenes comprising one of the characters at a time telling stories either with babble noise or no additional background noise showing real videos or animated avatars. Likeability ratings were obtained via a customized questionnaire with a 5-point Likert scale. We hypothesize a positive correlation between cortical tracking of speech and likeability ratings for the real videos and we will further explore whether this effect will extend to the animated avatars. Our results will shed light on the ecological validity of VE paradigms and the role of the speaker-listener-bonding for cortical speech tracking studies.
