Abstract
Ss estimated the number of black circles in three contextual conditions: OX (no white circles), 4X (four times as many white as black circles), and 16X (16 times as many white as black circles); they further estimated the number of black circles under two designs: independent and related samples. For independent samples, estimates were significantly greater for the 0X than for the 4X and 16X conditions, while the latter two did not differ. For the related sample, the 0X and 4X produced higher estimates than the 16X, while the former two did not differ.
