Table 5 Counts and proportions for each decision category of the identification procedures

From: Testing encoding specificity and the diagnostic feature-detection theory of eyewitness identification, with implications for showups, lineups, and partially disguised perpetrators

  1. ID = Identification; Internal = internal region of the face only. Some proportions do not add up to 1.0 due to rounding error
