The Inevitable and Unpredictable Role of Large Language Models in Education
This commentary critically complements a recent proposal that cognitive science can leverage Large Language Models (LLMs) to counter declining literacy. While recognizing the educational potential of LLMs, we highlight a significant trade‐off: their inherent design reduces users’ direct engagement with written text, undermining deeper literacy skills, especially in young learners. Acknowledging this tension is essential for developing pedagogical…
Do newborns detect prosodic violations in an unfamiliar language at birth
Experience with language starts prenatally, as the intrauterine environment allows speech prosody to get through. Martinez-Alvarez and colleagues (2023) demonstrated that newborns detect utterance-level prosodic violations in the language they heard prenatally, French. It remains unknown, however, whether this discrimination ability requires prenatal experience with a given language or whether newborns have an early sensitivity to the shapes of p…
Bias and noise in proportion estimation
What Infants Know and What They have to Learn about Language
The study of language acquisition during the first year of life is reviewed. We identified three areas that have contributed to our understanding of how the infant copes with linguistic signals to attain the most basic properties of its native language. Distributional properties present in the incoming utterances may allow infants to extract word candidates in the speech stream as shown in the impoverished conditions of artificial grammar studies…
Linguistic Constraints on Statistical Computations
Speech is produced mainly in continuous streams containing several words. Listeners can use the transitional probability (TP) between adjacent and non-adjacent syllables to segment "words" from a continuous stream of artificial speech, much as they use TPs to organize a variety of perceptual continua. It is thus possible that a general-purpose statistical device exploits any speech unit to achieve segmentation of speech streams. Alternatively, la…
Signal-Driven Computations in Speech Processing
Learning a language requires both statistical computations to identify words in speech and algebraic-like computations to discover higher level (grammatical) structure. Here we show that these computations can be influenced by subtle cues in the speech signal. After a short familiarization to a continuous speech stream, adult listeners are able to segment it using powerful statistics, but they fail to extract the structural regularities included …
