T1  - How pitch change and final lengthening cue boundary perception in German: converging evidence from ERPs and prosodic judgements
JF  - Language, cognition and neuroscience
N2  - This study examines the role of pitch and final lengthening in German intonation phrase boundary (IPB) perception. Since a prosody-related event-related potential (ERP) component termed Closure Positive Shift reflects the processing of major prosodic boundaries, we combined ERP and behavioural measures (i.e. a prosodic judgement task) to systematically test the impact of sole and combined cue occurrences on IPB perception. In two experiments we investigated whether adult listeners perceived an IPB in acoustically manipulated speech material that contained none, one, or two of the prosodic boundary cues. Both ERP and behavioural results suggest that pitch and final lengthening cues have to occur in combination to trigger IPB perception. Hence, the combination of behavioural and electrophysiological measures provides a comprehensive insight into prosodic boundary cue perception in German and leads to an argument in favour of interrelated cues from the frequency (i.e. pitch change) and the time (i.e. final lengthening) domain.

T1  - Choice of analysis pathway dramatically affects statistical outcomes in breaking continuous flash suppression
JF  - Scientific reports
N2  - Breaking Continuous Flash Suppression (bCFS) has been adopted as an appealing means to study human visual awareness, but the literature is beclouded by inconsistent and contradictory results. Although previous reviews have focused chiefly on design pitfalls and instances of false reasoning, we show in this study that the choice of analysis pathway can have severe effects on the statistical output when applied to bCFS data. Using a representative dataset designed to address a specific controversy in the realm of language processing under bCFS, namely whether psycholinguistic variables affect access to awareness, we present a range of analysis methods based on real instances in the published literature, and indicate how each approach affects the perceived outcome. We provide a summary of published bCFS studies indicating the use of data transformation and trimming, and highlight that more compelling analysis methods are sparsely used in this field. We discuss potential interpretations based on both classical and more complex analyses, to highlight how these differ. We conclude that an adherence to openly available data and analysis pathways could provide a great benefit to this field, so that conclusions can be tested against multiple analyses as standard practices are updated.
