CITE WITHOUT PERMISSION Working Memory Architecture and its Implications for Hypertext Design: Insight from Deaf Signer Users Research
نویسندگان
چکیده
Starting from models of working memory and hypertext navigation, this research focused on how the specific demands of hypertext systems could be adapted to fulfill the memory peculiarities of deaf signer users. We manipulated the Verbal and Visuospatial storage demands of a hypertext information retrieval task. The results showed that differences in accuracy, response time, and lostness between deaf signers and hearing non-signers are smaller in spatial-demanding hypertext compared to verbal-demanding hypertext structure. In addition, independently of Web demands, good reader-users (both hearing and deaf) were better than low readers. These results suggest design guidelines of web accessibility for deaf people. In the theoretical plane, the data could support the hypothesis that the effect of SL use over WM could be generalized to others visuo-spatial tasks which are non-exclusively linguistic (Emmorey, 1998, 2002) as hypertext navigation.

Hyperlink format, categorization abilities and memory span as contributors to deaf users hypertext access.
Sixty deaf and hearing students were asked to search for goods in a Hypertext Supermarket with either graphical or textual links of high typicality, frequency, and familiarity. Additionally, they performed a picture and word categorization task and two working memory span tasks (spatial and verbal). Results showed that deaf students were faster in graphical than in verbal hypertext when the num...
متن کاملWorking memory for sign language: a window into the architecture of the working memory system.
Traditionally, working memory has been divided into two major domains: verbal and visuo-spatial. The verbal domain of working memory can be characterized either by its relationship to language or by its grounding in auditory processing. Because of this ambiguity, languages that are not auditory and vocal (i.e., signed languages) pose a challenge to this conception of working memory. We describe...
متن کاملDeaf children's non-verbal working memory is impacted by their language experience
Several recent studies have suggested that deaf children perform more poorly on working memory tasks compared to hearing children, but these studies have not been able to determine whether this poorer performance arises directly from deafness itself or from deaf children's reduced language exposure. The issue remains unresolved because findings come mostly from (1) tasks that are verbal as oppo...
متن کاملImproving deaf users' accessibility in hypertext information retrieval: are graphical interfaces useful for them?
This paper explores the effect of substituting textual links for graphical ones on the performance of deaf signers in Hypertext Information Retrieval (HIR). Both deaf and hearing users found more targets, were faster and became less disoriented in the Verbal hypertext interface than in the Graphical one. Deaf users were outperformed by hearing users in all conditions except in short paths with ...
متن کاملEmbedded Memory Test Strategies and Repair
The demand of self-testing proportionally increases with memory size in System on Chip (SoC). SoC architecture normally occupies the majority of its area by memories. Due to increase in density of embedded memories, there is a need of self-testing mechanism in SoC design. Therefore, this research study focuses on this problem and introduces a smooth solution for self-testing. In the proposed m...
