Project Description

These data are from the project TaalSpel or Language Play. They were collected in Belgium by Annick De Houwer in cooperation with Marc H. Bornstein These data are being jointly donated by Annick De Houwer & Marc H. Bornstein; the transcripts are owned by and donated by Annick De Houwer.

Recordings are from the same children at 13 and 20 months in two settings at home -- freeplay sessions with a standardized set of toys and eating. Filmers were silent. Children include 31 Dutch monolinguals, 31 Dutch-French bilinguals, and 3 Dutch-English bilinguals. The video at 13 months includes two 15-minute sessions, one with food and one with play with MOT. At 20 months, the video includes three contexts: FOOD + LEARN (play with MOT with standardized set of toys) + PLAY (CHI alone, with same standardized set of toys, done after LEARN session), 3 x 10 minutes, toddler + mother, recorded at home, filmer silent (FOOD filmed either before LEARN+PLAY, or after; LEARN filmed before PLAY). Note that what is called play.mlu in the 20M coded transcripts actually refers to the videos called LEARN (so, in interaction with MOT). Five minutes of each interactional context were transcribed and coded at each age for 20 minutes for each child in total.

The data for the bilinguals is in the /Biling section of CHILDES. For the bilinguals, some sessions are in Dutch, others in French, one in English. All recordings of monolingual families are in Dutch.

Transcripts are organized according to (1) main language used (NL, FR, ENG) and (2) kind of family (bilingual/monolingual) and (3) context (food/play).
