Databases centered on infant language acquisition



In the first two years of life, infants make astounding strides in language acquisition. The following databases that tabulate empirical research on key language acquisition phenomena happening during that time frame:
  • InVarInf Community-augmented meta-analysis on individual variation between performance in infant speech perception tasks and some other factor 
  • InPhonDB Community-augmented meta-analysis on infant speech sound discrimination (visualize the contents of this database
    • Scope expanded! Now contains vowels and consonants
  • InWordDB Community-augmented meta-analysis on infants' recognition of words (and wordforms) 
    • Scope expanded! Now contains: Segmentation of natural native speech; natural nonnative speech; content versus function words
    • Null results from unpublished word contributed (2 records)
All databases are open to contributions, be it by adding data or expanding their scope.

Please also refer to Metalab, for more databases that are scheduled to become CAMAs.

The following databases are also of potential interest:
  • DBIfNIRS Table with all infant fNIRS studies (language or otherwise) published before 2011 (and some thereafter) 
  • Report on infant-directed speech Tables on the acoustic characteristics of infant-, compared to adult-, directed speech and their effects on infant perception and development
