摘要:
AbstractIn attempting to account for inferior mathematical attainment among deaf children of all ages, some researchers have proposed that observed deficits may be partly the result of an absence of vocalization and subvocalization in the acquisition and execution of arithmetic by the deaf. When performing mental arithmetic, hearing children, it is claimed, rely on covert counting mechanisms based on internalized speech, while their deaf counterparts, due to a lack of articulatory prowess, are unable to utilize such mechanisms and instead are forced to adopt other less effective methods based on associative retrieval of arithmetical facts from long‐term memory. The present study sought to throw light on these assertions. Ten prelingually profoundly deaf 12‐13‐year‐olds, and 10 hearing controls were required to solve the 100 simple addition combinations. Analysis of response times revealed strong similarities between the two groups, with all children appearing to employ mechanisms based on covert counting. Implications of the present results are discussed in the light of previous f
