AB  - The spatial cueing paradigm (Posner Quarterly Journal of Experimental Psychology 
      32:3-25, 1980) has often been used to investigate the time course of the 
      deployment of visual attention in space. In a series of eight experiments we 
      investigated whether spatial cues would not only enhance processing of stimuli 
      presented at cued locations, but also enhance processing of the entire texture in 
      which the stimuli were presented. Results showed highest accuracy for responses 
      to stimuli presented at cued locations, a replication of the traditional cueing 
      effect (Posner 1980). Additionally, stimuli presented at uncued locations were 
      responded to with higher accuracy when they were presented inside the same 
      texture as the cued location, as compared with stimuli presented outside the 
      texture with the cued location. To investigate this texture advantage for both 
      automatic and voluntary attention deployment, exogenous and endogenous cues were 
      used. The texture advantage was observed for short interstimulus intervals (ISIs) 
      of 50 and 100 ms for exogenous cues and for a longer ISI of 200 ms for endogenous 
      cues. These findings indicate that the arrangement of task-irrelevant visual 
      stimuli also can have a large impact on the cueing effect. This suggests that 
      visual spatial attention spreads texture-wise across the visual field. Control 
      experiments revealed that the homogeneity within texture elements contributes 
      most to the effect but that the texture advantage is a function of both 
      orientation contrast at the texture border and homogeneity within texture 
      elements.
