AB  - Visual short-term memory for the contrast and spatial frequency of sinusoidal 
      gratings was measured in a delayed discrimination task in which the 2 stimuli to 
      be compared were separated in time by 1-10 s interstimulus intervals (ISIs). 
      Delayed discrimination thresholds for spatial frequency and contrast were 
      compared, both when the 2 types of thresholds were measured in separate blocks of 
      trials and when the 2 types of measures were randomly intermixed in an 
      uncertainty paradigm, which required participants to process information about 
      both dimensions on each trial. In both cases, accuracy of memory for spatial 
      frequency was independent of ISI, but memory for contrast decreased as ISI 
      increased. Performance was lower in the uncertainty case, but only by an amount 
      predicted by statistical decision theory for independent sources. The results are 
      consistent with a model assuming a set of parallel special-purpose visual 
      discrimination and short-term memory mechanisms.
