Single Actor vs Sample Clauses
Single Actor vs. Alternating Sessions
A. Single Actor sessions. The data were divided into three 10-trial blocks per session, for a total of six trial blocks (Figure 3). Subjects paired with in-group partners showed a significant increase in the percent of prosocial choices across the first session from the first trial block (trials 1-10) to the third trial block (trials 21-30; equal rewards: t11 = 3.37, P = 0.003, one-tailed; unequal: t11 = 2.006, P = 0.035, one-tailed). Although the percent of prosocial choices by out-group partners also increased over the course of the first session, this difference was not significant (equal: t11 = 0.23, NS; unequal: t11 = 0.462, NS). During the second Single Actor session, there is no significant change in the percent of prosocial choices across the trial blocks for any reward/partner conditions (in- group/equal: F 2,22 = 0.106, NS; in-group/unequal: F 2, 22 = 0.868, NS; out-group/equal: F 2,22 = 0.949, NS; out-group/unequal F 2,22 = 0.221, NS). There were also no significant differences between the two Single Actor sessions for any reward/partner conditions (F 1,11 = .▇▇▇, ▇▇). Therefore, the data from both sessions were combined for analysis. These results suggest that while learning may have taken place during the first session (particularly for the in-group pairs), subjects had learned the values of the tokens prior to moving on to the Alternating sessions. Additionally, there were no significant differences between experienced and novice subjects for any of the reward/partner conditions (in-group/equal: t = 0.176, NS; in-group/unequal: t = -▇.▇▇▇, ▇▇; out- 60 55 Out‐group In‐group 50 45 group/equal: t = -▇.▇▇▇, ▇▇; out-group/unequal: t = -▇.▇▇▇, ▇▇; α = 0.0125 (Bonferroni Correction)).
