Abstracts from presentations given at the 1990 International Congress on Education of the Deaf are organized by 12 major topics: development of language skills; communication; instruction; cognition and learning; educational policies and services; organization and administration of schools and programs; students with special needs; psychosocial development and physical/mental health; education and work; college and continuing education; audiological and medical aspects of deafness; and deaf adults in society. Within each topic, the abstracts are organized alphabetically by last name of the presenter or first author. Two appendices provide an index of authors, co-authors, and panelists and a list of presenters and chairpersons. (JDD)
