Letter-Number Sequencing

You will hear (or see) a mixed-up string of letters and numbers. Hold it in mind, reorder it, and enter it back:

The rule: numbers first, from smallest to largest — then letters, in alphabetical order.

Presented: R  3  K  1  →  Correct answer: 1  3  K  R

Each sequence is played once — no replays. Sequences get longer as you go. Ten items, three trials each; the task ends early if you miss all three trials of an item. Sequences are generated fresh every session.

□ Spoken (recommended)

Sequences are read aloud, one item per second, like an examiner would. Requires sound on.

□ Visual flash

Each character flashes on screen one at a time. Use if audio isn't available.

Name (optional — appears on the report)

This is an informal instructional analogue inspired by the letter-number sequencing paradigm. It is not the WAIS, is not normed, and should not be used for diagnosis or clinical decision-making. All sequences are randomly generated each session.
