The paper describes an experiment in which 52 deaf children (7-19 years old) and 36 normal hearing children (7-16 years old) were given several Piagetian conservation tasks to determine if the conventional instructions are the basis for conservation failure in deaf children and to examine the order in which deaf Ss acquired various forms of…

Twenty-four profoundly deaf children (7 to 13 years old) from a residential school were presented with conservation problems of liquid, matter, weight, and volume. Analyses of variance showed that age was significant beyond the .01 level and type of task (conservation) at the .25 level. No significant sex effect was found. Differences among means…

All of the children were presented conservation of liquid and weight problems and 12 metaphor items. The results suggest that hearing loss did not affect the solution of either conservation or metaphor. (Author)

The study examined the rate and order of conservation in 24 deaf children, ages 8.2 to 12.9 years using standard Piagetian instructions and procedures in sign language. Even the older children failed to demonstrate control over the conservation concept suggesting the presence of a cognitive difference in deaf children. (DB)

Conservation forms were presented to 24 day- and 16 residential-school deaf students (ages 7 to 19) and 36 normally hearing control Ss (4 to 16), using conventional Piagetian instructions and attribute specific instructions. It was found that deafness does not apparently account for conservation differences found between deaf and normally hearing…

The study with 23 severely hearing impaired adolescents found that subjects using cued speech performed highest on Piagetian conservation problems, the oral-aural group performed better on linguistically-sensitive metaphor problems. Differences were not, however, statistically significant. (Author/DB)

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…
