Figure 7. Correlation between relative T_IS and contact.

Linear regressions, coefficients of determination (R²), and p-values for Pearson product moment correlations on T_IS relative to huddlemates (T_IS ^rel) and (a) total contacts, (b) contacts with females, and (c) contacts with males, during the warm and cool phases of Experiment 2 (left and right, respectively). Asterisks indicate significant correlation, using a criterion of α = .05/6 = 0083. As can be seen, there was no relationship between T_IS ^rel and contact during the warm phase, and a significant correlation between T_IS ^rel and both total contacts and contacts with females, but not contacts with males, during the cool phase.
