Mildly mentally retarded adolescents (N=14) and mental age-matched nonretarded children participated in three experiments examining language processing efficiency. Results suggested that the retarded and nonretarded differ in the speed with which the semantic-analytic processes are executed but not necessarily the phonological encoding processes…

An auditory Stroop task was administered to 20 children with hearing impairment (ages 3-10) and 60 normal-hearing children. Results suggest that the voice-gender and semantic dimensions of speech were not processed independently by children with or without hearing loss. Speech processing by children with hearing impairment was carried out in a…

The technique developed in this research paper for analyzing the information in charts and graphs is designed to reveal design flaws in the display that may prevent them from conveying information effectively. This analytic scheme requires isolating four types of constituents in a display and specifying their structure and interrelations at the…

With reference to Chinese language and its unique orthography, evidence for language-related differences in manners of information processing is reviewed. These differences include visual form perception, manipulation of numbers, and memory versus manipulation and elaboration of verbal information. (Author/RH)

Experienced deaf-blind users (N=10) of sign language tested their ability to receive signed messages including isolated signs and sentences. A set of 122 isolated signs was received with an average accuracy of 87%. Signed sentence reception accuracy ranged from 60-85%, with errors accounted for primarily by deletions and phonological or…
