Note. Intercept is left out as uninformative from all models. Means 1 and 2 correspond to Cooperative and Competitive for Mode, and Male and Female for Gender, respectively. For Mode×Gender interactions, the rows denote Male and Female, and the columns denote Cooperative and Competitive, in that order. The p-values significant after controlling the false discovery rate are bolded.
