  abstract  = {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.},

  abstract  = {Speech and action sequences are continuous streams of information that can be segmented into sub-units. In both domains, this segmentation can be facilitated by perceptual cues contained within the information stream. In speech, prosodic cues (e.g., a pause, pre-boundary lengthening, and pitch rise) mark boundaries between words and phrases, while boundaries between actions of an action sequence can be marked by kinematic cues (e.g., a pause, pre-boundary deceleration). The processing of prosodic boundary cues evokes an Event-related Potentials (ERP) component known as the Closure Positive Shift (CPS), and it is possible that the CPS reflects domaingeneral cognitive processes involved in segmentation, given that the CPS is also evoked by boundaries between subunits of non-speech auditory stimuli. This study further probed the domain-generality of the CPS and its underlying processes by investigating electrophysiological correlates of the processing of boundary cues in sequences of spoken verbs (auditory stimuli; Experiment 1; N = 23 adults) and actions (visual stimuli; Experiment 2; N = 23 adults). The EEG data from both experiments revealed a CPS-like broadly distributed positivity during the 250 ms prior to the onset of the post-boundary word or action, indicating similar electrophysiological correlates of boundary processing across domains, suggesting that the cognitive processes underlying speech and action segmentation might also be shared.},
