Insights

Phonological short-term memory, assessed via nonword repetition, is crucial for language development in both preterm and full-term children. Early assessment aids clinical practice for preterm infants.

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Speech and Language Pathology

Background:

  • Preterm birth can impact cognitive development, including phonological short-term memory.
  • Phonological short-term memory is a key predictor of language acquisition.

Purpose of the Study:

  • To investigate phonological short-term memory in preterm children.
  • To explore the relationship between phonological short-term memory and later language skills in preterm and full-term children.

Main Methods:

  • A nonword repetition task was administered to preterm (n=74) and full-term (n=60) children at 36 months.
  • Standardized language assessments were conducted at 36 and 54 months.
  • Regression analyses examined the predictive power of nonword repetition on language outcomes.

Main Results:

  • Preterm children had higher rates of non-completion for the nonword repetition task.
  • Among completers, no significant performance differences were found between preterm and full-term groups.
  • Nonword repetition scores at 36 months significantly predicted language skills at 54 months for both groups.

Conclusions:

  • Phonological short-term memory is vital for language development in all children, regardless of birth status.
  • These findings support the clinical importance of assessing phonological short-term memory in preterm infants.

Language

Language is a unique communication system that uses words and systematic rules to organize and transmit information. Unlike other forms of communication, which may involve postures, movements, odors, or vocalizations, language relies on symbols and grammar. This makes human communication distinct from that of other species, who also communicate but do not use language in the same way humans do.
Corballis and Suddendorf (2007) and Tomasello and Rakoczy (2003) highlight the role of language in...

Components of Language

Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs.

Language Development

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...
