Attention to Hierarchical Level Influences Attentional Selection of Spatial Scale
Flevaris, Anastasia V.; Bentin, Shlomo; Robertson, Lynn C.
Journal of Experimental Psychology: Human Perception and Performance, v37 n1 p12-22 Feb 2011
Ample evidence suggests that global perception may involve low spatial frequency (LSF) processing and that local perception may involve high spatial frequency (HSF) processing (Shulman, Sullivan, Gish, & Sakoda, 1986; Shulman & Wilson, 1987; Robertson, 1996). It is debated whether SF selection is a low-level mechanism associating global and local information with "absolute" LSF and HSF content, or whether it is a higher level mechanism involving a selective process that defines the SF range in which global and local can then be "relatively" defined. The present study provides support for the latter claim by demonstrating that allocating attention to global or local levels of hierarchical displays biased selection of LSFs or HSFs, respectively, in subsequently presented compound gratings. This bias occurred despite a change in the response dimension (from letter identification in the hierarchical stimulus to orientation discrimination in the grating) and despite a difference in retinal location of the hierarchical stimuli and the grating stimulus. Moreover, the bias was determined by the relationship between the 2 SFs in the compound grating (i.e., their relative frequency) rather than the absolute SF values.
