a–b, IT selectivity among the restricted-experience objects (a) and bias test objects (b) for each monkey. a, Red points indicate the fraction of IT neurons selective among the restricted-experience objects at the trained position (counterbalanced across the two monkeys as shown). Blue points show selectivity within the same object set at the eccentricity-matched, nontrained position. Selectivity was determined by ANOVA (see Materials and Methods), and a range of significance levels (p values) used for deeming a neuron to be selective is indicated. Note that in all cases, both monkeys showed a tendency for more selectivity at the trained position (red), relative to the nontrained position (blue). b, Same conventions as in a for the bias test objects (Fig. 1a) presented at the same two retinal positions (filled green squares indicate the position that was trained with the restricted-experience objects). Please note that, because the bias test objects were chosen to have greater within-object set shape differences than the restricted-experience object set (see Materials and Methods), it is unsafe to compare the absolute fraction of neurons showing shape selectivity among the two object sets.
