Previous research has shown that in different languages ironic speech is acoustically modulated compared to literal speech,and these modulations are assumed to aid the listener in the comprehension process by acting as cues that mark utterances as ironic. The present study was conducted to identify paraverbal features of German 'ironic criticism' that may(More)

This study evaluated the use of imagined interactions in speech research, by comparing speech addressed to imaginary speech partners with natural speech addressed to genuine interaction partners. Samples of speech directed to an imaginary infant (IDS), foreigner (FDS) and adult (ADS) produced by ten female students were acoustically analysed and also rated(More)
This study evaluated the use of imagined interactions in speech research, by comparing speech addressed to imaginary speech partners with natural speech addressed to genuine interaction partners. The shape of pitch contours derived from target words of samples of imaginary infant (IDS), foreigner (FDS) and British adult (ADS) directed speech produced by ten(More)
The study investigated whether the facilitating effect of high text comprehensibility on lay recipients’ inclination to rely on their own decision about scientific claims is mitigated if the presented information is controversial. Moreover, it was assessed whether the impact of both information features is mediated by perceptions of topic complexity. Lay(More)
Science popularization fulfills the important task of making scientific knowledge understandable and accessible for the lay public. However, the simplification of information required to achieve this accessibility may lead to the risk of audiences relying overly strongly on their own epistemic capabilities when making judgments about scientific claims.(More)
We evaluated two speech research paradigms by comparing standardized sentences to ‘free speech’ (both produced by students without interaction partner). Samples of infant(IDS), foreigner(FDS) and adult-directed speech (ADS) were acoustically analyzed for F0 and hyperarticulation. No difference for hyperarticulation was found between IDS, FDS and ADS, which(More)
The present study set out to investigate the influence of two metatextual features-presentation format and source expertiseon lay readers’ explanation of conflicts in scientific information. Secondary school students read partly conflicting information about a medical topic, which was either presented in one single document or in four different documents,(More)
The present study investigated whether laypersons are aware of their own knowledge limitations when having to decide about the acceptability of scientific knowledge claims. Specifically, we tested whether laypeople are more prone to discount their actual dependence on experts after having read simplified science depictions. Lay recipients read scientific(More)
