Spatial frequencies as a medium for guiding attention: comment on Lamb, Yund, and Pond (1999)
M. R. Lamb, E. W. Yund, and H. M. Pond (1999) question L. C. Robertson's (1996) earlier arguments that attention can be guided by spatial frequencies when searching for a target in complex visual patterns. The 2 major findings they report to argue against Robertson's conclusions are discussed and found inadequate for the purposes of abandoning this hypothesis. Instead, findings reported in the accompanying article in combination with previous findings reported by 2 of the same authors (M. R. Lamb & E. W. Yund, 1996) provide converging evidence to support spatial frequency as a medium for guiding attention.
