Project Description

The participants included in this corpus are 30 mother-child pairs. This cross-sectional data set includes 10 dyads in each of the Preverbal (M=8 months), Early speech (M=13 months), and Multi-word (M=27 months) group. The data were collected at a mock apartment laboratory in Seoul National University. It consists of a foyer, a living room, a bedroom and a kitchen. We equipped the apartment with age-appropriate books and toys to simulate natural environment of a chlid's home.

The infant-mother dyads were first given 40 minutes of free-play time. Mothers were told to interact with their infants as they would normally do at home. Researchers monitored the interaction at a different room remotely via four wall-mounted cameras. After the play session, we made a phone call to the mother and reminded her to move on to the next task of calling one of their family members or friends and talk for a few minutes. Most of them had a chat with their mother or husband on the phone. In the few cases where the father came along, he entered the lab to chat with the mother. The researchers then entered the room, and talked with the mother for a few minutes. The total duration of the recording is about 50 minutes for each file.

The data were transcribed in Korean in the main participant tiers. We also provide a Roman transliteration in the %ort tier, adopting the Yale romanization system.
