Estimates of parameters dP, b and g of the 2-HT eyewitness identification model for the data reported by Karageorge and Zajac70 and by Wilcock and Bull [74, Experiment 2].

| dP | b | g | dP | b | g | ||
| Wildcard | .37 (.15) | .37 (.09) | .67 (.10) | Practice | .40 (.09) | .00 (.05) | .83 (.07) |

Values in parentheses represent standard errors. Within the model used as a comparison standard, parameters dP and g were estimated separately for the wildcard and the control conditions70 and for the culprit-absent practice and the control conditions [74, Experiment 2]. Parameter b was set to be equal between the experimental conditions. dP = probability of detecting the presence of the culprit; b = probability of biased suspect selection; g = probability of guessing-based selection among the lineup members.
