AbstractWhere and what we attend to is not only determined by our current goals but also by what we have encountered in the past. Recent studies have shown that people learn to extract statistical regularities in the environment resulting in attentional suppression of high-probability distractor locations, effectively reducing capture by a distractor. Here, we asked whether this statistical learning is dependent on working memory resources. The additional singleton task in which one location was more likely to contain a distractor was combined with a concurrent visual working memory task (Experiment 1) and a spatial working memory task (Experiment 2). The result showed that learning to suppress this high-probability location was not at all affected by working memory load. We conclude that learning to suppress a location is an implicit and automatic process that does not rely on visual or spatial working memory capacity, nor on executive control resources. We speculate that extracting regularities from the environment likely relies on long-term memory processes.

Working Memory Load

Past research has inconsistently distinguished the neural substrates of various types of working memory. Task design and individual performance differences are known to alter patterns of brain response during working-memory tasks. These task and individual differences may have produced discrepancies in imaging findings. This study of 50 healthy adults ( Mage = 19.6 yr., SD = .8) examined performance during various parametric manipulations of a verbal and spatial n-back working-memory task. Performance systematically dissociated on the basis of working-memory load, working memory type, and stimulus difficulty, with participants having greater accuracy but slower response time during conditions requiring verbal versus spatial working memory. These findings hold implications for cognitive and neuroimaging studies of verbal and spatial working memory and highlight the importance of considering both task design and individual behavior.

Oculomotor Activity

The structure of working memory has components responsible for the storage of verbal and visualspatial information; despite the fairly detailed study of the functions and mechanisms of their work, the question of their mutual influence is still open. Studies on the verbal working memory load influence on visual search performance (a task requiring the use of visual-spatial working memory resources) it was found that the load on the verbal working memory leads to increased efficiency of target detection. The results of the analysis of oculomotor activity during visual search also point out that the implementation of such tasks under verbal working memory load is accompanied by an increase in cognitive tension and of the degree of search automaticity. The results may indicate the interaction of verbal and visual-spatial working memory components that share non-specific cognitive resources.

Subsequent Search Misses

The article investigated the role of spatial working memory in visual search for multiple targets, in particular, in subsequent search misses effect. This phenomenon is the second target omission after the first target has been found in visual search task. One of the theoretical interpretations of subsequent search misses is the lack of resources (attention and/or working memory) after the first target is found. Experiment investigated dual-target visual search efficiency in standard conditions and with additional spatial working memory load. Additional working memory load did not have any significant impact in multiple target visual search efficiency. The results can due to the role of object, but not spatial working memory in this task. Alternative explanation assumes using special tools and strategies.
