DESCRIPTION:Some events attract our attention even when we are engaged in 
 a task for which these events are irrelevant. Previous research on this ki
 nd of attentional capture focused mainly on spatial factors. It showed tha
 t onset of new objects are more salient in capturing attention than a sudd
 en change in object features. The current study points to a temporal facto
 r\, over and above the importance of new objects. Two experiments show tha
 t feature changes capture attention as effectively as new objects provided
  that they occur during a period of temporal calm\, where no other display
  changes occurred. The results show that this unique change hypothesis app
 lies to changes in color\, in motion and even to the sudden appearance of 
 new objects. A third experiment examines the effect of mixing color change
 s with the sudden onsets. Under these conditions temporal calm is no longe
 r a requirement for capture by color changes.
