Table 3. Correlation coefficients between the group average payoff and the group average, b₁, b₂ and b₁ + b₂ in Control, IR, IP and IRP.

	Control	IR	IP	IRP
b₁	−0.0006	0.1678	0.3795^*	0.4036^*
b₂	0.7173^*	−0.0503	−0.2663	−0.2853

The symbol “*” denotes that the correlation is strong, i.e., P-value < 0.01.
