Familiarity, group exposure and risking behavior in gambling.
Then, the connectivity indices were separated into two groups in accordance with music familiarity (low and high), and a unified index was calculated to represent the overall index for all subject-song pairs in each familiarity group.
We then used a median split to allocate participants to either a 'high familiarity' or a 'low familiarity' group (median = 43 occasions per year).
To explore the three-way interaction, for the low- and high- familiarity groups separately, and for each level of meal variety, Tukey's post-hoc tests were used to explore differences between estimates of expected satiation and perceived volume.
By contrast, we saw much greater correspondence in the low-familiarity group (compare panels A and B in Fig. 3).
In the high-familiarity group, estimates of expected satiation and perceived volume differed significantly when one, two and three different foods were present (critical difference at 1% = 21.2, critical difference at 5% = 18.5).
By contrast, in the low-familiarity group, a significant difference was only observed when a single food type was present (critical difference at 1% = 21.8, critical difference at 5% = 19.1).
As anticipated, we also found a significant three-way interaction F(4.3, 277.9) = 2.4, p = .04. 1 In the high-familiarity group, we saw relatively marked differences between matches in our two tasks, especially in the low variety meals (meal variety levels one to three).
In our dataset, we separated the data from songs into a high familiarity data group (4 6 familiarity scores) and a low familiarity data group (1 3 familiarity scores).
Possibly, we artificially selected dogs to, like us, have disassociated familiarity and group status, but this needs testing.
Studying chimpanzees also allows us to test whether human ingroup-outgroup empathy bias is rooted in evolved mechanisms assessing social closeness, familiarity, and group status.
