Memory
Object Pointing Memory
Click every symbol once. After each correct click, the board reshuffles. Previously clicked symbols stay visible and unmarked, so you have to remember what you already chose.

About this test
Object Pointing Memory is based on a self-ordered pointing task. A group of symbols is shown, and the goal is to click each one once. The board reshuffles after every correct click.
The challenge is that already-clicked symbols are not marked. They stay on the board as traps, so the task depends on remembering which items have already been chosen.
This version uses one symbol category per level and removes color from emoji-like symbols. That makes simple color strategies less useful, such as clicking all yellow symbols first and all red symbols later.
What it measures
- Working memory
- Memory for previous choices
- Resistance to repeating an old response
- Search strategy
- Attention under increasing item load
How scoring works
The score is the total number of correct clicks before the run ends. Each level adds more symbols. A perfect run reaches 414 points.
Why categories are used
If every level mixes very different colors and object types, the task can become too easy to chunk into simple groups. For example, a player might click all yellow items first, then all red items, instead of remembering individual choices.
Using one category at a time keeps the symbols more similar in structure, while still making them visually distinct enough to tell apart. The category also changes between levels and does not repeat twice in a row.
