A validation study of the age-of-acquisition norms

A validation study of the age-of-acquisition norms collected by Ghyselinck, De Moor, & Brysbaert.

To assess the validity of The AoA-norms collected by Ghyselinck, De Moor and Brysbaert (2000), we presented a sample of the words to children from the last year of Kindergarten (Experiment 1) and the last year of primary school (Experiment2).

Experiment 1

Alphabetical listing of 254 validated words together with their rated AoA, logarithmic frequency and the evaluation of the three judges. For each word we mention:

  1. The percentage of children that knew the word without a cue
  2. The percentage of children that knew the word after a cue was given
  3. The percentage of children that gave a wrong answer after the four alternatives
  4. The percentage of children that refused to give an answer

Experiment 2

Alphabetical listing of the 410 validated words together with their rated AoA and the percentage of children that correctly indicated the meaning of the word. For each word we mention:

  1. The percentage of children that correctly indicated the meaning of the word
  2. The percentage of children that did not know the meaning of the word and ringed the option 'I don't know what a ... is'
  3. The percentage of children that chose the wrong alternative
