Values in parentheses represent standard errors. Within the model used as a comparison standard, parameters dP and g were estimated separately for fair and unfair lineups. Parameter dA was set to be equal between the fair and the unfair-lineup conditions. dP = probability of detecting the presence of the culprit; g = probability of guessing-based selection among the lineup members; dA = probability of detecting the absence of the culprit.
