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.

Spatial Locations

"Working memory (WM) has been shown to be an important factor in visual search. For instance, there is evidence that both spatial and visual WM load lead to a decrease in search performance, resulting in a longer time to complete a search. However, the findings regarding search efficiency, i.e., search time as a function of display size, are less clear. This measure has been reported to be affected by spatial but not visual WM load. In three experiments, with approximately 20 participants each, we tested how two different types of spatial WM load affect visual search in terms of search performance and efficiency. In all experiments, participants were asked to memorize the spatial locations of two (low load) or four items (high load) presented either serially (Experiment 1) or simultaneously (Experiments 2 and 3). After that, they had to search for a target letter in a display of 5, 10 or 15 letters. In Experiment 3, participants additionally performed a verbal WM task. A control condition with no memory load (search only) was also included in each experiment. The results showed that, compared to the search-only condition, search times increased when spatial load was added. This was regardless of the type of spatial WM load. No search-time differences were found between the low and high-load condition. The additional verbal WM task had no effect on search performance. Furthermore, and in contrast to previous findings, search efficiency was not affected by either type of spatial WM load. These results suggest that visual search performance, but not search efficiency, is affected by spatial WM load."

Recent research has pointed to two possible causes of mathematical (dis-)ability: working memory and number sense, although only few studies have compared the relations between working memory and mathematics and between number sense and mathematics. In this study, both constructs were studied in relation to mathematics in general, and to mathematical learning disabilities (MLD) in particular. The sample consisted of 154 children aged between 6 and 10 years, including 26 children with MLD. Children performing low on either number sense or visual-spatial working memory scored lower on math tests than children without such a weakness. Children with a double weakness scored the lowest. These results confirm the important role of both visual-spatial working memory and number sense in mathematical development.
