(1) Checking Time has been subject to logarithmic transformation and standardization, hence its mean of ‘0’ and S.D. of ‘1’. When calculations are conducted on the raw data, the mean time taken to check is 275.86 s (approximately 4 and a half minutes), with a standard deviation of 644.92 s; this is heavily skewed however, and the median time to check is: 0 seconds (i.e., immediate checking on alert); (2) ‘Conscientiousness’ is Level‐2 data that has been standardized, but this has been entered into this analysis at Level‐1, meaning that the same score is repeated for each candidate's Level‐1 data correlations; (3) Two‐tailed Pearson's product moment correlations are significant at *p < .05; **p < .01.
