  1. b is the unstandardized slope, CIlower and CIupper are the lower and upper bounds of the slope’s 95% confidence interval, SE is the standard error of the slope, df are the degrees of freedom for that effect, t-value tests whether b is different from zero, p-value reflects the probability of t-value given the slope is zero, and r is a correlation coefficient reflecting the partial effect size. The talking condition was coded with Talking = 1, No Talking = −1. The cooperative condition was coded with Cooperative = 1, Competitive = −1. Talking Cooperative (n = 32); Talking Competitive (n = 32); No Talking Cooperative (n = 30); No Talking Competitive (n = 40).
