Project Description

The participants were from a Japanese community in the Washington, D.C. area. All children were at the beginning of the one-word period and living in a family that spoke only Japanese among themselves. The children had varying degrees of exposure to English.

The data were collected through a series of recordings, in two to three week intervals, of spontaneous utterances rather than by controlled elicitation techniques. Audio recordings were made on standard cassette tapes with a Sony WM-D6C analog tape recorder and a Sony ECM-909A microphone. There were also video-recordings made on super 8 cassette tapes with a Samsung SCX915 camcorder.

The data were transcribed using a standard Romanization system for Japanese and IPA. The target adult form was determined from the context of the utterance. Indeterminable utterances were removed from the analysis. Spontaneous speech and imitations of the adult’s utterances were coded for. In the case of imitations, the full adult utterance is provided.
