AB  - In two experiments, Ss indicated for a series of trials whether or not two 
      pictures of common objects had the same name (a positive or negative response, 
      respectively). The pictures were separated by one of three interstimulus 
      intervals (ISis), and reaction time (RT) was recorded. In Experiment I, positive 
      trials involved pictures that were identical (identity match), mirror images 
      (mirror match), or physically different but had the same name (name match). The 
      stimuli came from either an S set, in which name-match pairs were physically 
      similar, or a D set, in which name-match pairs were physically dissimilar. The 
      mean RTs for mirror and identity matches were virtually the same but faster than 
      name-match RTs, an advantage that decreased with increasing ISI. It was expected 
      that name-match RT for the S set would be less than for the D set, indicating a 
      facilitative effect of physical similarity; however, the identity-match RTs 
      showed the expected difference. These results were extended in Experiment II, 
      which involved only the identity and name matches, in pure sessions (which 
      included positive trials of just one type) or mixed sessions (which included both 
      types of positive trials). For mixed sessions, name- as well as identity-match 
      RTs differed between the S and D sets. These results provide evidence for the use 
      of visual codes in comparing nonidentical pictures, codes that apparently vary 
      with experimental context and task demands.
