AB  - Face perception studies investigated how spatial frequencies (SF) are extracted 
      from retinal display while forming a perceptual representation, or their 
      selective use during task-imposed categorization. Here we focused on the order of 
      encoding low-spatial frequencies (LSF) and high-spatial frequencies (HSF) from 
      perceptual representations into visual short-term memory (VSTM). We also 
      investigated whether different SF-ranges decay from VSTM at different rates 
      during a study-test stimulus-onset asynchrony. An old/new VSTM paradigm was used 
      in which two broadband faces formed the positive set and the probes preserved 
      either low or high SF ranges. Exposure time of 500 ms was sufficient to encode 
      both HSF and LSF in the perceptual representation (experiment 1). Nevertheless, 
      when the positive-set was exposed for 500 ms, LSF-probes were better recognized 
      in VSTM compared with HSF-probes; this effect vanished at 800-ms exposure time 
      (experiment 2). Backward masking the positive set exposed for 800 ms 
      re-established the LSF-probes advantage (experiment 3). The speed of decay up to 
      10 seconds was similar for LSF- and HSF-probes (experiment 4). These results 
      indicate that LSF are extracted and consolidated into VSTM faster than HSF, 
      supporting a coarse-to-fine order, while the decay from VSTM is not governed by 
      SF.
