  1. DV = dependent variable, SD = standard deviation, CI = confidence interval, Cohen’s d is the standardized effect size. Comparisons were conducted between Collab-Solo (transitioning from collaboration to solo work) and Solo-Solo (working solo in both tasks) conditions. T-tests were used to evaluate mean differences for each dependent variable. Significant results are bolded for emphasis.
