Full Programme
ProLetter-Number Sequencing
See a mixed sequence of letters and numbers, then recall all numbers ascending followed by all letters alphabetically.
Colour-Word Interference

Sustained Vigilance
Numbers flash one at a time. Tap only when you see a 3 followed immediately by a 7. Tests sustained and selective attention.
Immediate & Delayed Recall
Learn a word list, recall immediately, complete a distractor task, then recall again after a delay. Measures true memory consolidation.
Prospective Memory
Remember to do something specific when a trigger event occurs during another task. Directly mirrors medication compliance.
Impulse Brake
Watch a GO bar fill up. When STOP flashes, freeze instantly. Measures response inhibition, false starts, and reaction time.
Object Location Memory
Study where household objects are placed on a grid. After a delay, tap each object then tap where it belongs. Tests visuospatial and episodic memory.
Category Recall Challenge
Learn 9 items from 3 categories. Recall immediately, then complete a distractor task with interference items before recalling again. Tests semantic and delayed memory.
