Data for: Alignment of f0 peak in different pitch accent types affects perception of metrical stress

The paper related to this dataset investigates how stress perception in German is affected by different pitch accent types (with different f0 alignments). Experiment 1 showed more errors in stress identification when f0 peaks and stressed syllables were not aligned – despite phonological association of pitch accent and stressed syllable. Erroneous responses revealed a response bias towards the syllable with the f0 peak. In a visual-world eye-tracking study (Experiment 2), listeners fixated a stress competitor with initial stress more when the spoken target, which had penultimate stress, was realized with an early-peak accent (f0 peak preceding stressed syllable), compared to a condition with the f0 peak on the stressed syllable. Hence, high-pitched unstressed syllables are temporarily interpreted as stressed – a process directly affecting lexical activation. To investigate whether this stress competitor activation is guided by the frequent co-occurrence of high f0 and lexical stress, Experiment 3 increased the frequency of low-pitched stressed syllables in the immediate input. The effect of intonation on competitor fixations disappeared. The paper discusses these findings with respect to a frequency-based mechanism and their implications for the nature of f0 processing. On this platform, stimuli (wav-files) for all experiments are provided, along with datasets (raw data for stress judgements, Experiment 1, and eye-tracking experiments (Experiments 2 and 3)) and a R-Markdown file showing all steps in the statistical analysis (Exp. 1-3).
