BabyLex for Android

11 things about BabyLex

1. Don’t worry! This doesn’t mean your child has forgotten words – there is a margin of error for the estimate, i.e., a range where the app can make inaccuracies, and when you test the same child in shorter intervals, it is likely that the vocabulary estimate falls within this margin of error.

2. Once you have completed the test, you will see the result informing you the number of words your child likely produces from the long version of the vocabulary questionnaire (in other words, your child will likely produce that many words or more) and also a percentile score of your child – how she/he compares with other children of the same sex and age.

3. Using the BabyLex app you can follow the development of your child by completing the test as often as you like and seeing how your child’s vocabulary has increased.

4. So, it is just as likely that your child knows all the words on the list or none of the words on the list depending on how old s/he is and what words were randomly chosen by the app to test.

5. Don’t also worry if your child doesn’t say most of the words on the list – the words are chosen at random and are not tailored to the capabilities of particular age-groups.

6. The research: The BabyLex app features a novel approach that allows researchers and parents to assess reliably a child’s vocabulary within 2 minutes (as opposed to up to 45 minutes for full-sized tests).

7. We are also researchers in child psychology and thus we have developed an app to estimate your toddler’s vocabulary size.

8. We are not doctors, we are researchers who are also parents and want to use our research to allow parents an insight into the development of their child.

9. If you want a clinical evaluation of your child, please ask your pediatrician for contacts to the clinicians who can provide you such an evaluation.

10. We are parents and know how much fun it is to follow the development of your child.

11. Note: it is an estimate so if you complete the test too soon after you completed a previous one, it is possible that the score may also go down.
