Table 3.

Mean model results of three best-fitting models for each model group and sample (all participants vs. ingroup driven vs. equality driven); TI, trial information used to inform β₁ and β₂; z is the relative bias; an empty cell in z or sv means, that the parameter is fixed to 0.5 and 0, respectively; an empty cell for a, or t₀ means, that this parameter was fixed for all three stimuli types—otherwise the parameter was allowed to vary between the stimuli types.
