- Data is shown as mean ± SD (for normally distributed data) or median (IQR) (for not normally distributed data)
- Test results are expressed in z-scores. TAP: z-scores are based on median reaction-time. Visual recognition—short-term: assessed approximately 10 min after targets were presented. Memory consolidation after long-term took place after one night of sleep (approximately 10 h)
- Abbreviations: WMS Wechsler Memory Scale, LM logical memory, RAVLT Rey Auditory Verbal Learning Test, WAIS Wechsler Adult Intelligent Scale, TMT Trail Making test, BNT Boston Naming Test, TAP Test of Attentional Performance
- *Significant at p < 0.05
