    Charles A Collin
    School of Psychology, University of Ottawa, Ottawa, Ontario, Canada
    Percept Psychophys 68:879-89. 2006
    ..These results are compatible with the idea that a middle band of SFs will be most useful for any visual task and that the breadth of this optimal middle band will vary depending on task characteristics...

    Charles A Collin
    Dalhousie University, Halifax, Nova Scotia, Canada
    Percept Psychophys 67:354-64. 2005

    Acta Psychol (Amst) 138:143-54. 2011
