dc.description.abstract | Here we report, for the first time, a relationship between sensitivity to amplitude envelope
rise time in infants and their later vocabulary development. Recent research in auditory
neuroscience has revealed that amplitude envelope rise time plays a mechanistic
role in speech encoding. Accordingly, individual differences in infant discrimination of
amplitude envelope rise times could be expected to relate to individual differences in
language acquisition. A group of 50 infants taking part in a longitudinal study contributed
rise time discrimination thresholds when aged 7 and 10 months, and their vocabulary
development was measured at 3 years. Experimental measures of phonological
sensitivity were also administered at 3 years. Linear mixed effect models taking rise
time sensitivity as the dependent variable, and controlling for non‐verbal IQ, showed
significant predictive effects for vocabulary at 3 years, but not for the phonological
sensitivity measures. The significant longitudinal relationship between amplitude envelope
rise time discrimination and vocabulary development suggests that early rise
time discrimination abilities have an impact on speech processing by infants. | es_ES |
