## 🧠 Task Structure and Procedure

The task requires the user to classify a target card based on a hidden sorting rule (Color, Shape, or Number).

### Stimuli and Sorting

1.  **Reference Cards:** Four stationary reference cards appear at the top of the screen. Each card is unique across three properties:
    * **Card 0:** 1 Red Triangle
    * **Card 1:** 2 Green Stars
    * **Card 2:** 3 Yellow Diamonds
    * **Card 3:** 4 Blue Circles
2.  **Target Card:** A fifth card appears below the reference cards.
3.  **Classification:** The user classifies the target card by **clicking on one of the four reference cards**.
4.  **Feedback:** Immediate feedback ("Correct" or "Wrong") is provided after each click, but the sorting rule is not revealed.

### Rules and Progression

* A total of **64 target cards** are presented.
* **Rule Change Criterion:** The sorting rule automatically changes after **10 consecutive correct answers**.
* **Rule Sequence:** The rules are presented in a fixed, repeating order for up to six categories: **Color, Shape, Number, Color, Shape, Number**.
* **Categories:** Successful completion of the sequence allows up to **six categories** to be achieved.
