ABSTRACT
The Serra-Sole longitudinal study includes 10 children. Five are monolingual Catalan, four are bilingual Catalan-Spanish, and one is monolingual Spanish. The Spanish-speaking child (#10) is included in the Spanish directory. The other children are in the Catalan directory. The children were videotaped monthly from 1 to 4 years of age from 1986 to 1989. They were videotaped at their homes in spontaneous interaction with a familiar adult, usually the mother, in sessions of 30 to 45 minutes. A l l the children belong to middle-class families. The research project is entitled "Language acquisition in Catalan and Spanish children" and is directed by Miquel Serra (Universitat de Barcelona) and Rosa Sole (Universitat Autonoma de Barcelona). It has received support from the Spanish research council (Grants D G I C Y T PB84/0455; PB89/0317; PB91/0851; PB94/0886). The research assistants of the project have been: Montserrat Cortes, Connie Schultz, Elisabet Serrat, Vicens Torrents, and Melina Aparici . Cristina V i l a and Montse Capdevila have collaborated in different stages of it. The authors would appreciate receiving a copy, or a summary, of any work using the corpus.
