Table 2. Description and screenshots of the cognitive test battery.

1	Spatial span test (based on Corsi block tapping test) Outcome: Spatial short term memory Duration: ~90 seconds (self-adaptive, until 3 mistakes are made) Brain area: Right mid-ventrolateral area, parieto-occipital regions Description: The cognitive system that allows for temporary storage of spatial information in memory. Spatial short-term memory deals with the relationships between objects in space, as opposed to remembering the specific order of numbers or words involved in verbal short-term memory. Score: The maximum length of a sequence that is correctly repeated
2	Odd One Out Task Outcome: Deductive reasoning Duration: 180 seconds Brain area: Anterior frontal cortex, anterior cingulate, anterior insula / frontal operculum, inferior frontal sulcus, pre-supplementary motor area, intraparietal sulcus Description: The core cognitive ability to apply rules to information in order to arrive at a logical conclusion. Score: The number of correct answers – the number of wrong answers
3	Grammatical reasoning test Outcome: Verbal reasoning Duration: 90 seconds Brain area: frontal operculum, posterior temporal lobe, superior parietal lobe, dorsal prefrontal cortex, ventral prefrontal cortex Description: The ability to quickly understand and make valid conclusions about concepts expressed in words. Score: The number of correct answers – the number of wrong answers
4	Digit span task Outcome: Verbal, short term memory Duration: ~90 seconds (self-adaptive, until 3 mistakes are made) Brain area: Mid-ventrolateral prefrontal cortex, left temporo-parietal lobe, basal ganglia Description: Short-term memory is the cognitive system that allows for temporary storage of information in memory. Verbal short-term memory deals with numbers or words in a specific order, as opposed to spatial short-term memory. Score: The maximum length of a sequence that is correctly repeated
5	Double trouble task (based on Stroop Colour-Word Test) Outcome: response inhibition Duration: 90 seconds Brain area: Right prefrontal cortex. dorsolateral frontal cortex, left inferior frontal gyrus, dorsal striatum Description: The ability to concentrate on relevant information in order to make a correct response despite interference or distracting information. Score: The number of correct answers – the number of wrong answers
6	SART (Sustained Attention to Response) Outcome: sustained attention Duration: 4 minutes Brain area: frontal and parietal cortical areas, mostly in the right hemisphere. Description: The ability to maintain concentration for the whole 4 minutes so that one does not click/tap/press after a number 3. Score: The number of correct answers – the number of wrong answers
