Abstract: Using the Kaufman Assessment Battery for Children (K-ABC) Conant et al. (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 present study evaluated whether visual and auditory WM span were independent in Ugandan and Senegalese children.
Partial Text: In what has become the dominant model of memory organization, Baddeley and Hitch postulated a distinction between the control processes in memory and the structural memory stores . At the heart of the control processes is what is commonly referred to as “working memory”, which is comprised of two modality-specific subsidiary systems that serve an attention-based central or executive process. The first of the working memory systems is the visual-spatial sketch pad. This system is involved in the processing and memory of information of a more distinctively visual and/or spatial nature and is often instrumental in more adaptive motor control and response. The other subsidiary system is the phonological loop, which is involved in the processing and memory of auditory verbal material.
