ENAC Memory N-Back

IntellectualPSY1

Letters come up one at a time, and for each one you say whether it’s the same letter as the one three, four or five before it. Capitals and small letters count as the same. The exam format is two tests back to back: a 3-back then a 4-back for ENAC EPL, a 4-back then a 5-back for Air France Cadets. It hasn’t been set since 2020.

~7 min

Overview

Each comparison is easy. Holding three to five letters in order while new ones arrive is the test. Keep the last few letters in your head as a string, said by name, so a B and a b need no second look. When a letter comes, compare it with the first of the string, click, then drop that one and add the new letter to the end. So with p c b held and a g on screen: No, and now it’s c b g. For a 4-back or a 5-back, split the string in two (two and two, or three and two), or give each letter a finger. And if you lose the string, don’t dig for it. Click your best guess and hold the next letters as a new string: you’re back in step a few letters later.

Assessments

Part of the ENAC EPL selection (PSY1) battery as “Memory N-Back”.

Letters one at a time, each judged against the one N letters before, with upper and lower case counting as the same letter. Set from 2014 to 2018, as a 3-back then a 4-back from 2016, and not since. The battery brings tests back, so it is worth an hour before the day.

Part of the Air France Cadets selection at ENAC (PSY1) battery as “Memory N-Back”.

The same letter test, set from 2018 to February 2020, last as a 4-back then a 5-back. It has not been set since.

Battery mappings are based on public information and may change.

Eleven letters, three back

On the day these come one at a time. Each shows for 1 second, then it goes and you get 3 seconds to answer. The first three get no question. Each one after that does: is it the same letter as the one three before it? Capitals and small letters count as the same, so C and c are a match.

One letter at a time

The same eleven letters, the way the test shows them. There’s no clock here, the letter stays up while you answer, and each answer is corrected before the next letter.

Game Phases

1

Hold a String, Shift One

Keep the last three to five letters in order. Compare each new letter with the first, then drop that one and add the new one.

2

Click in the Window

The letter’s gone when Yes and No come on, and you’ve got 3 seconds. Click as soon as you know, then use what’s left to update your string.

3

One Place Off Is a No

If a letter matches the one a place nearer or a place further back, it’s still a No. Some letters are put there to catch exactly that.

4

Don’t Race the Letters

Clicking early doesn’t bring the next letter sooner. Wait for it, or you’ll shift your string one letter too far.
