Which of the following is an example of a search asymmetry?
 
  a) It is easier to declare that a target is present than it is to declare that a target is absent.
   b) It is easier to declare that a target is present in a smaller display than in a larger display.
   c) It is easier to find a target that includes a feature than it is to find one that doesn't include the feature.
   d) It is easier to find a target using conjunction search than it is to find a target using feature search.

Question 2

Fleck and Mitroff thought that missing low-prevalence items in visual search might be due to overly fast response, and tested this by presenting visual displays with line drawings of various objects for visual search.
 
  They allowed participants to make an additional response (i.e., a correction) if they felt that their just-made
   response had been in error. Under these conditions:
   a) the effect of low-prevalence was greatly exaggerated.
   b) the effect of low-prevalence was greatly reduced.
   c) nothing changed  low prevalence targets were missed just as much as before.
   d) the effects of low-prevalence were greater than in Wolfe et al., which featured actual bag-screening displays.
