On the standard PGG block after the punishment instruction, those who never made a zero contribution (i.e., always contributed) in this block (N = 60) scored higher BIS-anxiety (M = 3.20, SD =.58); compared to those who made zero contribution (i.e., free rode) on at least one of the games in the block (N = 19, BIS-anxiety scores M = 2.89, SD =.78; t (77) = −1.83, p =.07).
The dry period from June to September has a zero contribution to storm.
As in Keser and van Winden [ 37], participants were divided into zero contributors (i.e. those, who made at least one zero contribution across all the games in the block,) and non-zero contributors (i.e. those, who never made a zero contribution during any of the games in a particular block).
