The 2-HT eyewitness identification model32,34. The rounded rectangles on the left represent the lineup types presented to the participants: culprit-present and culprit-absent lineups. The parameters attached to the branches of the trees denote transition probabilities of the latent cognitive processes postulated by the model (dP: probability of detecting the presence of the culprit; b: probability of biased selection of the suspect; g: probability of guessing-based selection among the lineup members; dA: probability of detecting the absence of the culprit). Lineup size represents the number of persons in the lineup. The rectangles on the right side show the categories of the observable responses.
