    • Object-based attention with endogenous cuing and positional certainty 

      Chen, Z.; Cave, K.R. (University of Canterbury. Psychology., 2008)
      Previous studies have concluded that object-based attention does not always arise if attention is cued endogenously (Macquistan, 1997) or if the target location is known with certainty (Shomstein & Yantis, 2002). In the ...
    • An object-based cost of visual filtering 

      Chen, Z. (University of Canterbury. Psychology., 2000)
      Although evidence for object-based attention has been reported in a variety of paradigms, few studies have examined directly the relationship between the processing efficiency of the targets and the number of ...
