Pearson’s correlation coefficient between COVID-19 responses and CPT performance in Experiment 2. Skill index is calculated as No-go accuracy divided by Go RT

In the correlation analysis between income and other variables, participants who chose the answer “I prefer not to answer this question” were excluded, leading to N = 197. All other analyses had N = 204. Only the following correlation reached Bonferroni adjusted alpha: participants with older age showed slower RT in go responses, Pearson’s r = .23, p = .0007.
