Separation of the Systems for Color and Spatial Manipulation in Working Memory Revealed by a Dual-task Procedure

Harald M. Mohr, David E. J. Linden
2005 Journal of Cognitive Neuroscience  
Conversely, interference did occur when both components of a dual-task tapped into the spatial system. Thus, color and spatial information are manipulated in parallel.  ...  & The manipulation of different kinds of content is fundamental to working memory.  ...  In the first step, a dual-task paradigm was used in which the participants were asked mentally to mix colors and manipulate spatial information separately as single tasks, or simultaneously as a dual task  ...

Concurrent working memory load can reduce distraction

S.-Y. Kim, M.-S. Kim, M. M. Chun
2005 Proceedings of the National Academy of Sciences of the United States of America  
However, WM is not a unitary mechanism. In addition to the central executive, the WM system contains separate stores for verbal information and for visuospatial information (12, 19) .  ...  According to Baddeley's (12) influential model, the WM system contains a central executive that helps maintain and manipulate information in the mind, which is important for most cognitive tasks.  ...  In the Stroop task-only condition, a 500-ms blank screen replaced the memory array, and the memory test display was removed. The dual-task and single-task conditions were tested in separate blocks.  ...

When do spatial and visual working memory interact?

Justin N. Wood
2010 Attention, Perception & Psychophysics  
In a dual-task paradigm, participants attempted to remember locations in a spatial working memory task and colored objects in a visual working memory task.  ...  Further, this study reveals a set of conditions in which spatial and visual working memory can be isolated from one another.

Memory binding .  ...  Acknowledgments This work was supported by the University of Southern California, Harvard University, and a National Institute of Health (NIH) National Research Service Award (NRSA, grant F31MH075298).  ...

Spatial working memory load affects counting but not subitizing in enumeration

T. Shimomura, T. Kumada
2011 Journal of Vision  
Furthermore, in both spatial and nonspatial memory tasks, neither subitizing efficiency nor subitizing range was affected by amount of imposed memory load.  ...  Under a dual-task situation, participants performed an enumeration task in conjunction with either a spatial (Experiment 1) or a nonspatial visual (Experiment 2) working memory task.  ...  If so, both the range and efficiency of subitizing should be attenuated by the presence of spatial working memory load in the dual-task condition.  ...
