Correlations between WCST Metrics and Behavioral Validation Variables [95% CIs]
| Number of Efficient Shifts | Cognitive Persistence | |
|---|---|---|
| Abstract Reasoning | ||
| TCFCa | −0.33 [−0.41, −0.24]* | 0.09 [−0.07, 0.25] |
| Working Memory | ||
| WMS-audb | 0.38 [0.22, 0.51]* | 0.01 [−0.15, 0.16] |
| WMS-visb | 0.34 [0.17, 0.48]* | 0.04 [−0.13, 0.22] |
| Performance Consistency | ||
| CPT SEc | −0.13 [−0.31, 0.08] | −0.22 [−0.40, −0.03]* |
Note.
TCFC: trials to complete first category. WMS-aud: Wechsler Memory Scale auditory subtest. WMS-vis: Wechsler Memory Scale visual subtest. CPT SE: Continuous Performance Test standard error of hit reaction time.
Higher TCFC indicates poorer abstract reasoning.
WMS data available for 135 participants.
CPT data available for 108 participants. Higher CPT SE indicates less consistent performance.
95% CIs estimated from non-parametric bootstrap resampling did not include 0.
