Estimates of parameters dP, b and dA of the 2-HT eyewitness identification model for the data reported by Malpass and Devine67 and by Lampinen et al. [68, Experiment 1].

| Pre-lineup instructions | Parameter estimates | Pre-lineup instructions | Parameter estimates | ||||
| dP | b | dA | dP | b | dA | ||
| One-sided | .68 (.11) | .01 (.06) | .21 (.30) | One-sided | .30 (.05) | .00 (.02) | .04 (.03) |
| Two-sided | .81 (.09) | Two-sided | .26 (.03) | ||||
Values in parentheses represent standard errors. Within the model used as a comparison standard, parameter dP was estimated separately for one-sided and two-sided pre-lineup instructions. Parameters b and dA were each set to be equal between the one-sided and the two-sided pre-lineup instruction conditions. dP = probability of detecting the presence of the culprit; b = probability of biased suspect selection; dA = probability of detecting the absence of the culprit.
