Age of Acquisition

Age of Acquisition is a psycholinguistic variable referring to the age at which a word is typically learned. For example, the word 'penguin' is typically learned at a younger age than the word 'albatros'. Studies in psycholinguistics suggest that age of acquisition has an effect on the speed of reading words.[1] It is a particularly strong variable in predicting the speed of picture naming.[2] It has been generally found that words that are more frequent, shorter, more familiar and refer to concrete concepts are learned earlier than more complex words.[3]

Norms[edit]

Sets of normative values for age of acquisition for large sets of words have been developed.

  • Kuperman, Stadthagen-Gonzalez, and Brysbaert [4]
  • Gilhooly and Logie.[5]
  • Morrison et al.[6]

Relation to other variables[edit]

It has been disputed whether age of acquisition has an effect on word tasks on its own or by virtue of its covariance with other variables such as word frequency.[7] Alternatively, it has been suggested that the age of acquisition is related to the fact that an earlier learned word has been encountered more often.[8] These issues were partially resolved in an article by Ghyselinck, Lewis and Brysbaert.[9]

Alternatively there have been discussions of the effect that the age of acquisition has on learning a second language.
