The paper reviews research trends and findings on the development of personality in deaf individuals. The first section, "Adolescent and Adult Deaf Personalities," focuses on studies in the psychological literature that tend to promulgate stereotypical views of deaf people by reflecting researcher bias rather than researcher findings. The second section, "Personality Development in Deaf Children," examines in depth the consistent finding that deaf children who grow up in deaf families generally have better social, emotional, and cognitive development than do deaf children from hearing families. In the final section, "Implications for Parents of Deaf Children," a planned intervention called a "Sensory Integration Program for Deaf Infants" is recommended. Hearing parents of deaf children are encouraged to learn from deaf parents their ways of touching, communicating, and playing with young deaf children. Contains 85 references. (DB)
