TL;DR
Interference between tasks occurred if there was explicit retrieval of the verbal load during maintenance of a visual array and when especially large silent verbal and visual loads were held concurrently, suggesting central storage along with code-specific passive storage.
Abstract
Examinations of interference between verbal and visual materials in working memory have produced mixed results. If there is a central form of storage (e.g., the focus of attention; N. Cowan, 2001), then cross-domain interference should be obtained. The authors examined this question with a visual-array comparison task (S. J. Luck & E. K. Vogel, 1997) combined with various verbal memory load conditions. Interference between tasks occurred if there was explicit retrieval of the verbal load during maintenance of a visual array. The effect was localized in the maintenance period of the visual task and was not the result of articulation per se. Interference also occurred when especially large silent verbal and visual loads were held concurrently. These results suggest central storage along with code-specific passive storage.

The revised model differs from the old principally in focussing attention on the processes of integrating information, rather than on the isolation of the subsystems, which provides a better basis for tackling the more complex aspects of executive control in working memory.

A wide variety of data on capacity limits suggesting that the smaller capacity limit in short-term memory tasks is real is brought together and a capacity limit for the focus of attention is proposed.

It is demonstrated that it is possible to retain information about only four colours or orientations in visual working memory at one time, but it is also possible to retaining both the colour and the orientation of four objects, indicating that visual workingMemory stores integrated objects rather than individual features.

To account for the large demands on working memory during text comprehension and expert performance, the traditional models of working memory involving temporary storage must be extended to include working memory based on storage in long-term memory.

The authors argue that working memory capacity and fluid intelligence reflect the ability to keep a representation active, particularly in the face of interference and distraction, and discuss the relationship of this capability to controlled attention, and the functions of the prefrontal cortex.

This work provides electrophysiological evidence for lateralized activity in humans that reflects the encoding and maintenance of items in visual memory and provides a strong neurophysiological predictor of an individual's capacity, allowing a direct relationship between neural activity and memory capacity.

The findings support a domain-general view of WM capacity, in which executive-attention processes drive the broad predictive utility of WM span measures, and domain-specific storage and rehearsal processes relate more strongly to domain- specific aspects of complex cognition.

Functional magnetic resonance imaging is used to suggest that activity in the posterior parietal cortex is tightly correlated with the limited amount of scene information that can be stored in visual short-term memory, and suggests that the posterior PAR cortex is a key neural locus of the authors' impoverished mental representation of the visual world.

The authors examined the effects of divided attention at encoding and retrieval in free recall, cued recall, and recognition memory in 4 experiments and found memory performance was sensitive to changes in task emphasis at encoding but not at retrieval.

The rate of consolidation was approximately 50 ms per item, which is considerably faster than previous proposals, and performance on the memory task was impaired when the delay between the colored squares and the masks was short.

Streams of visual and/or auditory inputs containing occasional targets to be identified and recalled suggest a modality-specific restriction to concurrent attention and awareness; visual attention to one simple target does not restrict concurrent auditory attention to another.

It is suggested that Cowan's revisiting of the magic number reflects a misinterpretation of the working memory model of Baddeley (1986), resulting in a danger of focusing attention on pseudo-problems rather than genuine disparities between his approach and my own.
