Visuospatial bootstrapping: aging and the facilitation of verbal memory by spatial displays
(American Psychological Association, 2015-06-09) Calia, Clara; Darling, Stephen; Allen, R. J.; Havelka, J.
Recent studies on verbal immediate serial recall show evidence of the integration of information from verbal and visuospatial short-term memory with long-term memory representations. Verbal serial recall is improved when the information is arranged in a familiar spatially distributed pattern, such as a telephone keypad. This pattern, termed visuospatial bootstrapping, is consistent with the existence within working memory of an episodic buffer (Baddeley, 2000). The present experiment aimed to investigate whether similar results would be obtained in a sample of older adults. Older (55–76) and younger (19–35) adults carried out visual serial recall in 3 visual display conditions that have previously been used to demonstrate visuospatial bootstrapping. Results demonstrated better performance when digits were presented in a typical telephone keypad display. Although digit serial recall declined with age, there was no evidence that this visuospatial bootstrapping effect differed in size between older and younger adults. Theoretical and practical implications of these results are described.
Visuospatial bootstrapping: Implicit binding of verbal working memory to visuospatial representations in children and adults
(Elsevier, 2014-03-25) Darling, Stephen; Parker, M-J; Goodall, Karen; Havelka, J.; Allen, R. J.
When participants carry out visually presented digit serial recall, their performance is better if they are given the opportunity to encode extra visuospatial information at encoding-a phenomenon that has been termed visuospatial bootstrapping. This bootstrapping is the result of integration of information from different modality-specific short-term memory systems and visuospatial knowledge in long term memory, and it can be understood in the context of recent models of working memory that address multimodal binding (e.g., models incorporating an episodic buffer). Here we report a cross-sectional developmental study that demonstrated visuospatial bootstrapping in adults (n = 18) and 9-year-old children (n = 15) but not in 6-year-old children (n = 18). This is the first developmental study addressing visuospatial bootstrapping, and results demonstrate that the developmental trajectory of bootstrapping is different from that of basic verbal and visuospatial working memory. This pattern suggests that bootstrapping (and hence integrative functions such as those associated with the episodic buffer) emerge independent of the development of basic working memory slave systems during childhood. 2013 Elsevier Inc.
