Statistical learning is the ability for humans and other animals to extract statistical regularities from the world around them to learn about the environment. Although statistical learning is now thought to be a generalized learning mechanism, the phenomenon was first identified in human infant language acquisition.
Statistical learning has been shown to play a large role in language acquisition, but social interaction appears to be a necessary component of learning as well. In one study, infants presented with audio or audiovisual recordings of Mandarin speakers failed to distinguish the phonemes of the language. [11] [12] This implies that simply hearing ...
This research yielded many publications that are considered classics in the statistical learning literature, including a 1996 Science article, "Statistical Learning in 8-Month-Old Infants". [12] Some of his recent work has extended original findings about infants' ability to track environmental statistics in speech to the visual world.
With Richard N. Aslin and Jenny Saffran, [14] Newport introduced statistical learning to the study of natural language acquisition: the hypothesis that infants, young children, and adults acquire the structure of languages by computing the statistics of the co-occurrence of elements - which elements of the sound stream occur most frequently ...
For example, if English-learning infants are exposed to a prevoiced /d/ to voiceless unaspirated /t/ continuum (similar to the /d/ - /t/ distinction in Spanish) with the majority of the tokens occurring near the endpoints of the continuum, i.e., showing extreme prevoicing versus long voice onset times (bimodal distribution) they are better at ...
By age 10, children's vocabulary development through reading moves away from learning concrete words to learning abstract words. [ 69 ] Generally, both conversation and reading involve at least one of the four principles of context that are used in word learning and vocabulary development: physical context, prior knowledge, social context and ...
The U.S. Justice Department has launched a probe into UnitedHealth's Medicare billing practices in recent months, the Wall Street Journal reported on Friday, sending the healthcare conglomerate's ...
A babbling infant, age 6 months, making ba and ma sounds. Babbling is a stage in child development and a state in language acquisition during which an infant appears to be experimenting with uttering articulate sounds, but does not yet produce any recognizable words.
