Directors used fewer Descriptors in Round 2 (M = 4.17, SD = 1.77) than in Round 1 (M = 12.23, SD = 3.75), t(47) = 14.06, p<.0001, 95% CI [6.91, 9.21], d = 2.03 (Liu et al., under review).
on this measure, we replicated effects found in the laboratory "in the wild": Participant pairs became more efficient at referring to their targets in Round 2 than they had been in Round 1.
