AB  - In two experiments, we investigated the effects of exogenous cueing on visual 
      motion processing. The first experiment shows that the typical pattern of 
      reaction time (RT) effects, namely early facilitation and later inhibition of 
      return (IOR), can be obtained using a color change as exogenous cue and a 
      direction change as target. In the second experiment, we manipulated the validity 
      of the cue independently with respect to location and feature using transparent 
      motion stimuli. Facilitation of RTs with short cue-target interstimulus-intervals 
      (ISIs) was only evident for targets with both the valid location and the valid 
      feature. Furthermore, at longer cue-target intervals, RTs were prolonged for 
      targets at the cued location, irrespective of the cued feature. These results 
      demonstrate spatial and feature-based components of early facilitation and purely 
      spatial IOR.
