Assessments comprised of Frisian and Dutch receptive and productive vocabulary tests and speech samples of spontaneous speech in both languages. Measurement 1 (first test round) took place when the child was aged between 2;6-2;11 years, measurement 2 (second test round) when the child was aged between 3;0-3;5 years, and during measurement 3 (third test round), the child was aged between 3;6-3;11 years. Parental questionnaires revealed information on language input inside and outside the home. The SPSS-files contain characteristics of the subjects used in this project. Data collection took place in the period 2010-2012.The initial sample consisted of of 101 participants, which is the number of participants found in the file ‘2013 Jelske Dijkstra mixed model file ws.sav’. Three of these 101 participants came from mixed language families, which was discovered after parents had filled in their language questionnaires. These three participants were excluded from the study. Further, seven participants refused to carry out all vocabulary tests, moved away, or could not be tested in their non-verbal intelligence because they had already entered primary education. These participants were also excluded, ultimately leaving the final research group that comprised 91 participants. This is the number of participants most often mentioned in the project description and manuscript.The .SAV format of the datafiles were deposited by the Fryske Akademy. DANS added the .DTA and .POR formats of these files to ensure preservation and accessibility. For the same reason, DANS also added the .PDF format for the .DOC files. https://ssh.datastations.nl/oai doi:10.17026/DANS-ZQQ-KFN5 2025-12-03T01:00:46Z ddi:codebook:2_5
