Εάν επιθυμείτε να εκτελέσετε το σύνολο της συστοιχίας, παρακαλούμε να ακολουθήσετε την παρακάτω τυχαιοποιημένη σειρά: If you wish to execute the entirety of the battery, we suggest to follow this randomized order:
1 | Δοκιμασιες εργαζομενης μνημης 1 | Working memory tasks
Οδηγίες προς τον εξεταστή: Εκτελέστε την πρώτη προσπάθεια. Εάν είναι αποτυχημένη εκτελέστε και την δεύτερη. Εάν και η δεύτερη είναι αποτυχημένη, σταματήστε την παροχή των ασκήσεων αποθήκευσης και μεταβείτε στις ασκήσεις επεξεργασίας. You will see the activation of 2 lights with white color, and you must remember the order by which they were activated. After all lights are activated with white color, you must deactivate the lights in the order you remember from before, by using the mouse and clicking at each light.
Instructions to the examiner: Execute the first attempt. If the user fails, execute the second. If the second fails too, stop the execution of the Short-term store tasks and move on to the Central executive (processing) tasks.

Εάν και η δεύτερη είναι αποτυχημένη, σταματήστε την παροχή των ασκήσεων επεξεργασίας και μεταβείτε στις ασκήσεις ενημέρωσης. You will see the activation of 2 lights with white color, and you must remember the order by which they were activated. After all lights are activated with white color, you must deactivate the lights, by using the mouse and clicking at each light. Nevertheless, this time you must deactivate them in the reverse order. This means that you will start from the light that was activated last and you will progress to the light that was activated first.
Instructions to the examiner: Execute the first attempt. If the user fails, execute the second. If the second fails too, stop the execution of the Cental executive (processing) tasks and move on to the Updating & Episodic buffer tasks.

2 | Δοκιμασιες εποπτικου συστηματος προσοχης 2 | Attention control tests
3 | Δοκιμασιες εκτελεστικου ελεγχου 3 | Gognitive control tasks
(α) είτε όταν ακούτε νιαούρισμα,
(β) είτε όταν βλέπετε πρόβατο,
(γ) είτε όταν βλέπετε γάτα και ταυτόχρονα ακούτε βέλασμα (βλέπετε μια γάτα να βελάζει).
Ας ξεκινήσουμε με ένα παράδειγμα. Είστε έτοιμος/η; Next, you must do the same, meaning that you must deactivate each light (by pressing Enter), in the following cases:
(a) when meowing is heard,
(β) when the image of sheep exists below the light,
(γ) when the image of cat exists below the light, and at the same time you hear a sheep bleating (i.e. you see a cat bleating)
Lets start with an example. Are you ready?
