Error bars indicate mean + s.e.m for all the figures.
Figure 2 above provides the first evidence of our first hypothesis: Popularity promotes
pro-social behavior to a greater extent when decisions are public than when they are
private. If this hypothesis is true, we should expect more popular children behave more
generously in Public than in Private while less popular children don’t differ much in
sharing both in Public and Private.
From Figure 2, we can see that the most popular children share more in Public (1.6) than
Private (0.78), although the difference is not statistically significant (p=.18) due to the
low number of observations.
