For nearly half a century now, Garner interference has been serving as the gold standard measure of dimensional interaction and selective attention. But the mechanisms that generate Garner interference are still not well understood. The current study proposes a novel theory that ascribes the interference (and dimensional interaction in general) to…

Behavioral studies have reported interactions between number processing and spatial attention, suggesting that number processing involves shifting attention along a mental continuum on which numbers are represented in ascending order. However, direct evidence for attention shifts remains scarce, the respective contribution of the horizontal and…

Attention is crucial for effective learning. There is an emerging research trend that suggests attention can be improved by changing the structure of the learning task, leading to increased learning. This chapter reviews and reanalyzes studies of attention in educational settings with respect to the structure of the learning task. This analysis is…

The experiments conducted aimed to investigate whether reduced accuracy when counting stimuli presented in rapid temporal sequence in adults with dyslexia could be explained by a sensory processing deficit, a general slowing in processing speed or difficulties shifting attention between stimuli. To achieve these aims, the influence of the…

We report a study that examines whether the presentation of irrelevant, ordinal information at central fixation interacts with the allocation of attention beyond fixation. Previous research has demonstrated that number perception influences the allocation of spatial attention, such that the presentation of a spatially nonpredictive number at…

Previous research by Lidster and Bremner (1999) on young children's ability to coordinate two dimensions has shown that performance on construction tasks (in which children have to give the correct coordinates for a point in space that is already known) is superior to performance on interpretation tasks (in which children are given a pair of…
