    P M Greenwood
    Psychology Department, Catholic University of America, Washington, DC 20064, USA
    Percept Psychophys 61:837-59. 1999
    ..These results go beyond current models in suggesting that visuospatial attention possesses two dynamic properties--shifting in space and varying in scale--that are deployed independently, depending on task demands...

    P M Greenwood
    Cognitive Science Laboratory, Catholic University of America, Washington, DC 20064, USA
    J Int Neuropsychol Soc 6:705-26. 2000

    P M Greenwood
    Cognitive Science Laboratory, Catholic University of America, Washington, DC 20064, USA
    Percept Psychophys 66:3-22. 2004
    ..The results also provided evidence that cue size effects are attentional, not strategic. This evidence is consistent with the proposed model of attentional scaling in visual search...
