Short-term memory stages in sign vs. speech: the source of the serial span discrepancy.
Speakers generally outperform signers when asked to recall a list of unrelated verbal items. This phenomenon is well established, but its source has remained unclear. In this study, we evaluate the relative contribution of the three main processing stages of short-term memory--perception, encoding, and recall--in this effect. The present study factorially manipulates whether American Sign Langu...
متن کاملPersistent difference in short-term memory span between sign and speech: implications for cross-linguistic comparisons.
Short-term memory (STM) is thought to be limited in capacity to about 7 2 items for linguistic materials and 4 1 items for visuospatial information (Baddeley & Logie, 1999; Cowan, 2001). Recently, we (Boutla, Supalla, Newport, & Bavelier, 2004) challenged this dichotomy between linguistic and visuospatial STM by showing that STM capacity in users of American Sign Language (ASL) is also limited ...
متن کاملNo difference in short-term memory span between sign and speech.
The conclusions of Bavelier, Newport, Hall, Supalla, and Boutla (2006, this issue) are undermined by an inappropriate procedure for measuring articulation rate. They measured duration for reading a matrix of 200 letters (D. Bavelier, personal communication, May 17, 2006), which may involve a considerable load on visual attention, translation from print, and articulatory planning. This procedure...
متن کاملRoutes to short-term memory indexing: lessons from deaf native users of American Sign Language.
Models of working memory (WM) have been instrumental in understanding foundational cognitive processes and sources of individual differences. However, current models cannot conclusively explain the consistent group differences between deaf signers and hearing speakers on a number of short-term memory (STM) tasks. Here we take the perspective that these results are not due to a temporal order-pr...
متن کاملAnaphora: Insights from Sign Language (Summary)*
Sign language anaphora is realized very differently from its spoken language counterpart. In simple cases, an antecedent is associated with a locus in signing space, and an anaphoric link is obtained by pointing towards that locus to recover its semantic value. It has been argued that this mechanism is an overt realization of the device of coindexation in formal syntax and semantics. Summarizin...
