The ability to attribute false beliefs by 155 deaf children (ages 5 and 8) grouped by communication mode and parental hearing status was compared to that of 39 hearing children (ages 4 to 6). Effective representational abilities were demonstrated by deaf children of deaf parents, whereas those with hearing parents appeared delayed, with…

Deaf children with signing parents, nonnative signing deaf children, children from a hearing impaired unit, oral deaf children, and hearing controls were tested on theory of Mind (ToM) tasks and a British sign language receptive language test. Language ability correlated positively and significantly with ToM ability. Age underpinned the…

Three matched groups--hearing mother-hearing child, hearing mother-deaf child, and deaf mother-deaf child--were videotaped. Hearing mothers of deaf children were less likely to adapt their interactional strategies to meet their children's communicative needs and achieve intersubjectivity than were the other mothers. Results support Lev S.…

Reports an 18-month longitudinal study of sign language acquisition in very young children of deaf parents. Results indicate that some revision of views on cognitive prerequisites for language is necessary. Implications for nonspeaking populations and for developmental theory are discussed. Reviews briefly sign language training programs for…

The study with three profoundly deaf subjects (ages 11-13) investigated whether there is a chain of functional relationships among a method of interaction referred to as a mediation, a cognitive function referred to as spontaneous comparative behavior, the operation of categorization, and the reading comprehension tasks of using lexical cohesion…

Ties together the educational threads of teaching thinking skills and improving the intellectual performance in deaf learners. Identifies six criteria for curriculum or research decisions related to teaching for higher-level problem solving. Applications of these ideas to mathematics are left to the reader. (MDH)

Conservation and metaphor acquisition were studied in 35 hearing-impaired children (ages 6-19) using either cued speech or oral-aural communication. Significant positive relationships were found between conservation and metaphor in both communication modes, age and metaphor, and age and conservation. Neither conservation nor metaphor was related…

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.…

Compares the operational and sociomoral reasoning maturity of 70 deaf children with that of a sensory unimpaired control sample. Tests subjects individually on three Piagetian tasks, story pairs, and the concept of justice. Finds slower development of operational reasoning in the deaf children but comparable development in sociomoral reasoning.…
