    The ability to perceive lexical stress patterns has been shown to develop in language-specific ways. However, previous studies have examined this ability in languages that are either clearly stress-based (favoring the development of a preference for trochaic stress, like English and German) or syllable-based (favoring the development of no stress preferences, like French, Spanish, and Catalan) and/or where the frequency distributions of stress patterns provide clear data for a predominant pattern (like English and Hebrew). European Portuguese (EP) is a different type of language, which presents conflicting sets of cues related to rhythm, frequency, and stress correlates that challenge existing accounts of early stress perception. Using an anticipatory eye movement (AEM) paradigm implemented with eye-tracking, EP-learning infants at 5–6 months demonstrated sensitivity to the trochaic/iambic stress contrast, with evidence of asymmetrical perception or preference for iambic stress. These results are not predicted by the rhythmic account of developing stress perception, and suggest that the language-particular phonological patterns impacting the frequency of trochaic and iambic stress, beyond lexical words with two or more syllables, together with the prosodic correlates of stress, drive the early acquisition of lexical stress. Our findings provide the first evidence of sensitivity to stress patterns in the presence of segmental variability by 5–6 months, and highlight the importance of testing developing stress perception in languages with diverse combinations of rhythmic, phonological, and phonetic properties.

    Prosodic boundaries play a crucial role in signaling speech chunking, and may thus facilitate language learning. Previous studies have shown that infants are sensitive to prosodic boundaries and use them to segment speech. As prosodic boundary cues vary across languages, infants’ sensitivity to prosodic boundaries may also vary. The present study explores the perception of prosodic boundaries without the pause cue in European Portuguese 9- month-old infants. Using a familiarization procedure with visual fixation implemented with eye-tracking, infants were presented with sequences of delexicalized utterances with and without a prosodic boundary while watching a video with a randomly moving pattern. Successful discrimination was found, demonstrating that the pause is not a necessary cue by 9 months in line with the languagespecific adult pattern. Potential relations of discrimination abilities with later language outcomes are examined, and implications of our findings for crosslinguistic variation in the development of prosodic boundary perception are discussed.
