Correlation matrix for the full sample (n = 20) in participants’ slopes.
| Variables | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
|---|---|---|---|---|---|---|---|
| 1– Slope | 1.00 | 0.45 | 0.50* | −0.61** | −0.54* | ||
| −0.67** | 0.62** | ||||||
| 2– Trail making test | 1.00 | 0.17 | −0.29 | −0.42 | −0.42 | 0.70*** | |
| 3– Victoria stroop test | 1.00 | −0.29 | −0.44 | −0.43 | 0.83*** | ||
| 4– Digit symbol coding test | 1.00 | 0.46 | 0.84*** | −0.38 | |||
| 5– Symbol search test | 1.00 | 0.87*** | −0.56* | ||||
| 6– Index of IPS | 1.00 | −0.56* | |||||
| 7– Index of EFs | 1.00 |
Note. *p < 0.05; **p < 0.01; ***p < 0.001. Index was calculated as follows: Index of IPS = mean of scores z of Digit Symbol Coding Test and Symbol Search Test performance, Index of EFs = mean of scores z of Trail Making Test and Victoria Stroop Test performance.
