Introduction
I'm interested in language development as a situated phenomenon, co-existing and interacting with other neurobiological abilities (/disabilities).
I'm currently investigating on the neurosensory bases of early speech perception (0-12 months of life), in relation to the auditory system and the sensorimotor system

Auditory detection of the Amplitude Modulation (AM) of sounds, crucial for speech perception, improves until 10 years of age. This protracted development may not only be explained by sensory maturation, but also by im- provements in processing efficiency: the ability to make efficient use of available sensory information. This hy- pothesis was test...
Temporal modulations, especially amplitude modulations (AM), play a fundamental role in speech perception in noisy environments, as highlighted by psychoacoustic research. However, the mechanisms underlying AM processing and its contribution to speech perception in noise remain unclear. The present study combined both behavioral psychophysics and e...
Speech sounds convey relatively slow Amplitude Modulation cues whose processing plays a crucial role for speech comprehension. However, the development of AM processing and its interaction with speech intelligibility remains unclear. Previous studies suggested that AM processing development relates to changes in the central filtering of AM cues or...
Infants’ articulatory productivity has been correlated with the development of speech perception in several ways, including: preferences for listening to certain speech sounds (1-2) and the ability to categorizing phonemes (3) as well as neuroimaging studies showing that articulatory information is linked to infants’ emerging speech networks (4-6)....
The amplitude modulation following response (AMFR) is the steady-state auditory response signaling phase-locking to slow variations in the amplitude (AM) of auditory stimuli that provide fundamental acoustic information. From a developmental perspective, the AMFR has been recorded in sleeping infants, compared to sleeping or awake adults. The lack...
This study is a validation of the LENA system for the Italian language. In Study 1, to test LENA's accuracy, seventy-two 10-minute samples extracted from daylong LENA recordings were manually transcribed for 12 children longitudinally observed at 1;0 and 2;0. We found strong correlations between LENA and human estimates in the number of Adult Word...
Detection of amplitude modulations (AM) improves until 10 years of age. This development may not be explained only by sensory maturation but also by improvements in processing efficiency: the ability to make efficient use of available sensory information. This hypothesis was tested on 86 6-to-9-year-olds and 15 adults using AM-detection tasks asses...
Growing evidence shows that early speech processing relies on information extracted from speech production. In particular, production skills are linked to word-form processing, as more advanced producers prefer listening to pseudowords containing consonants they do not yet produce. However, it is unclear whether production affects word-form encodin...
Human infants are able to acquire quickly a language by “simple” exposure to speech. This remarkable capacity is rather surprising knowing that the auditory cortices are still developing until the end of adolescence. Many psychoacoustic studies have explored how the adult auditory system processes the acoustic components of speech, showing that slo...
It is still unclear whether the gradual improvement in amplitude-modulation (AM) sensitivity typically found in children up to 10 years of age reflects an improvement in “processing efficiency” (the central ability to use information extracted by sensory mechanisms). This hypothesis was tested by evaluating temporal integration for AM, a capacity r...
