![]() The present study evaluated whether visual and auditory WM span were independent in Ugandan and Senegalese children. (1999 observed that visual and auditory working memory ( WM span were independent in both younger and older children from DR Congo, but related in older American children and in Lao children. The relationship between visual-spatial and auditory-verbal working memory span in Senegalese and Ugandan children.įull Text Available BACKGROUND: Using the Kaufman Assessment Battery for Children (K-ABC Conant et al. Conclusions: Verbal WM assessed using visual tasks relates weakly to sentence recognition for degraded speech. CI users and NH peers demonstrated equivalent WM accuracy and response time for digit span and object span, and similar response times for symbol span, but contrary to our original predictions, CI users demonstrated better accuracy on symbol span than NH peers. As predicted, WM accuracy (and response times were best (and fastest for digit span, intermediate for object span, and worst (and slowest for symbol span. Results: Of the three measures of WM, digit span scores alone correlated with sentence recognition for CI users no correlations were found using these three measures for NH peers. Participants were tested for sentence recognition in quiet (CI users or after noise-vocoding (NH peers, along with WM using visual measures of digit span, object span, and symbol span. Methods: Cross-sectional study of 30 postlingually deaf adults with CIs and 34 NH controls. Likewise, response times, relating to processing demands, would be shortest for digit span, intermediate for object span, and longest for symbol span (3 CI users would demonstrate poorer and slower performance than NH peers on WM tasks, as a result of less efficient verbally mediated encoding strategies associated with a period of prolonged auditory deprivation. Three hypotheses were tested: (1 WM accuracy as assessed using three visual span measures — digits, objects, and symbols — would correlate with recognition scores for spectrally degraded speech (through a CI or when noise-vocoded (2 WM accuracy would be best for digit span, intermediate for object span, and lowest for symbol span, due to the increasing cognitive demands across these tasks. Visual working memory span in adults with cochlear implants: Some preliminary findingsĭirectory of Open Access Journals (Sweden)įull Text Available Objective: Neurocognitive functions, specifically verbal working memory ( WM, contribute to speech recognition in postlingual adults with cochlear implants (CIs and normal-hearing (NH listener shearing degraded speech. Depth of processing had minimal effect on… Two experiments compared the effects of depth of processing on working memory ( WM) and long-term memory (LTM) using a levels-of-processing (LOP) span task, a newly developed WM span procedure that involves processing to-be-remembered words based on their visual, phonological, or semantic characteristics.
